Africa a long time source of higher grade uranium ore has deposits on the peripheral edges of what I suspect to be a large impact zone much like the Middle, TN basin and later Howell/Petersburg impacts. Take a look at the Congo river tracing an interior crater circle just like the Elk and Richland river and creek do inside the Howell/Petersburg crater shown below.

Impact lateral wave phenomena. As I have encountered a lateral wave of iron from the Howell/Petersburg impact the Chicxulub impact also made a push of material from the Gulf in to Texas creating a vast arc of gypsum in West Texas, a closer in arc of fossil oyster shells and then a bit closer arc of uranium.

Middle TN is slightly radioactive. The Department of Energy, and DuPont have prospected the Middle TN area for possible mining. Additionally the lead deposits are tested and have various radioactive signatures. https://scholarworks.uark.edu/cgi/viewcontent.cgi?referer&httpsredir=1&article=1038&context=etd&fbclid=IwAR3W-fBYXCbR0WmZy4beMP9OL8BsMtNgtXRddiYQDBM1Ept6vIgmZ_CkEbc
While the extreme dense packing of impact will not cause a nuclear chain reaction; it will alter metals. The Howell, TN impact area is full of altered elements. The amount of energy from this impact is beyond any conventional laboratory can reproduce. It's source is not external but internal. It is not primarily heat based. It rips apart elements to a nano scale. Elements are also in contact with the explosion cloud as it progresses with waves that carry debris outward at different speeds. 
It is an event with cosmic implications. https://www.hillbillyu.com/kinetic-impact-explosion-crater
The physics of large are not linear with small impact explosions. More complete elemental conversion effects are produced with a very large dense bolide. And impact speed may have been even greater in early impacts not sourced from the asteroid belt or observable orbits we tract today. Cosmic speed decay: Big bang early impacts 60+ miles per second, Early earth surface impacts 30 miles per second, captured impacts 20 miles per second. 
Lead already dense contained in the meteor would be very susceptible to enrichment by heavy compression energy.  https://en.wikipedia.org/wiki/Blast_wave

Impact transformation is evident in the impact produced diamonds found. On December 8, 1954, a scientist from General Electric subjected black carbon powder to pressures of 50,000 atmosphere for 16 hours and made two small synthetic diamonds. So why not shock pressure uranium? Which is not becoming radon gas in Middle, TN. 
This article says cosmic but not impact are source of earth radioactive elements. https://www.world-nuclear.org/information-library/nuclear-fuel-cycle/uranium-resources/the-cosmic-origins-of-uranium.aspx
However why is so much radioactivity found in the Chattanooga Shale which is so connected to the Howell impact. https://www.youtube.com/watch?v=uluniXOrXtY

Uranium in Africa- And suspect impact effect. As I have studied with the Howell/Petersburg crater the models of impact lateral flow are all wrong. They use chemical and nuclear modeling and impact is a kinetic based energy. The lateral push wave is many times the subsequent crater. You can see my analysis of this at my study page: https://www.hillbillyu.com/kinetic-impact-explosion-crater and more background on African uranimum and craters is shown in the column to the right. Below is the current uranium estimate by the world nuclear association. 

(Updated April 2020)

  • Africa has considerable mineral deposits, including uranium.

  • Exploration and mine development is proceeding in countries which have not hitherto supplied uranium.

  • Gabon has been a significant uranium supplier in the past.

Please note:
The country papers on NamibiaNigerSouth Africa should be consulted for information in those areas.
This paper deals with other countries in Africa where uranium deposits having JORC or NI 43-101 compliant resources are known or understood to exist.

Algeria

A lot of uranium exploration occurred in the 1970s, resulting in the discovery of the Tahaggart deposit, as well as other mineralisation. The government reports reasonably assured resources (RAR) of 26,000 tU in the under $80/kg category. In September 2009 the National Mining Patrimony Agency put uranium exploration leases in the southern Tamanrasset province out for tender.

Botswana

A-Cap Resources' Letlhakane project in the northeast of the country comprises Gojwane and Serule orebodies, with Gorgon, Gorgon South, Mokobaesi, and Kraken prospects covering the former in a flat shallow deposit, to 75 m over 9 km. It is open to the west. In September 2015 the JORC-compliant project total was upgraded to 33,000 tU at 0.0167%U indicated and 108,000 tU inferred resources at 0.0172%U, all at 100 ppm cut-off. The ore is carnotite in calcrete and shallow open-pit mining with acid heap leach is expected to produce 1150 tU per year over 18 years, exported through Namibia. 

Australian-based A-Cap Resources applied for a mining licence in September 2015. In May 2016 the Department of Environmental Affairs approved the environmental impact statement (EIS), and in September a 22-year mining licence was issued. Construction was expected to start in 2018, but has been deferred for two years.

Jiangsu Shengan Resources Group Co Ltd (41.04%) and Ansheng Investment Co Ltd (19.78%) are the two largest shareholders in A-Cap. The company also has the Mea coal project about 120 km northwest and the Bolau coal project adjacent on the north, which it aims to sell.   

Along strike from Letlhakane, Impact Minerals based in Western Australia was exploring some prospective deposits in eastern Botswana including Lekobolo, with uranium mineralisation down to 45m. Further south, it had the Shoshong and Ikongwe prospects in calcrete. In May 2013 Impact announced the sale of four prospecting licences to local company Sechaba Natural Resources but this fell foul of licensing delays, and in 2014 Impact put its uranium exploration on hold.

Central African Republic

Having taken over UraMin Inc, Areva was proposing to develop the $200 million Bakouma project in the east of the country, originally discovered by Cogema (Areva) and more recently taken forward by UraMin Inc of Toronto. It aimed to start open pit mining at 1200 tU/yr, with ore grading 1.27%U. Following a test phase from 2010, the project was to ramp up to full production in 2014-15, but this is now delayed after expenditure of €107 million, due to low uranium prices and the need for further research on the metallurgy. It is a continental phosphate deposit unusual for its uranium content. Inferred resources of 36,475 tU at 0.03% were reported by Areva at the end of 2016. Areva Resources Centrafrique holds a 90% interest over ten discrete deposits, while the government holds a 10% free carried share. Civil unrest in the country is also a disincentive to development.

Congo, Democratic Republic

The Belgian Congo, as it then was, provided much of the uranium for the Manhattan Project in the early 1940s, particularly from the Shinkolobwe mine, 25 km west of Likasi in Katanga. There was some uranium mining subsequently by Union Miniere, to independence in 1960, when the shafts were sealed and guarded. About 25,000 tU was produced in the two decades until then.

The deposit has been unofficially mined since 1997 for cobalt. A UN report in 2004 described the situation as anarchistic. This has prompted some concern by the International Atomic Energy Agency on account of the possibility that some uranium might be finding its way to countries with illicit weapons programs. In the south-eastern region of Katanga the geology is contiguous with the Zambian copper belt.

In 2009 Areva signed a uranium exploration agreement for Katanga with the government, focused on Shinkolobwe, but has since said that it will not embark on any plans for mining while the country remains politically unstable.

The country ratified the Nuclear Non Proliferation Treaty in 1970.

Gabon

No current uranium mining occurs in Gabon, but exploration continues. Historically, uranium mining in Gabon has been closely linked with Niger due to the role of the French Atomic Energy Commission and Cogema (now Orano).

The Mounana uranium deposits in southeastern Gabon were discovered in 1956 by French Atomic Energy Commission (CEA) geologists and were mined from 1960 to 1999, producing nearly 28,000 tonnes of uranium. The best known of these deposits is Oklo, discovered in 1968, which produced over 14,000 tU. (Oklo is famous for its fossil nuclear reactors, which operated naturally in the wet sandstone orebody about two billion years ago.)

The Franceville Uranium Mines Company (COMUF) was formed in 1958 and undertook the mining and processing. It was 68.42% owned by Cogema and 25.8% by the national government.

The ore was mined largely in open cut operation but also underground, from five discrete orebodies with average ore grade of 0.37%. Milling was at Mounana. Production fluctuated from 400 to 1250 tU/yr, with a total of 12,147 tU coming from open pit mining and 15,725 tU from underground mining. Operations were shut down in mid 1999 due to a lack of economically recoverable reserves – RAR of 4830 tU @ under $130/kg is quoted. The facilities were dismantled and the site is in the final phase of rehabilitation.

Extraction of the ore began at the Mounana open pit mine (1960-75), followed by the mine at Oklo (1970-85). Ore was also extracted from underground mines, first at Mounana, then at Oklo (1977-97), and at Boyindzi (1980-91). During the last two years, the open pit at Mikouloungou, 60 km away, was mined (1997-99).

Up to 1975 some two million tonnes of tailings were released into the local Ngamaboungou creek and Mitembe-Likedi River system, along with mill effluent. Then four million tonnes were emplaced in the Mounana pit. In 1990 a tailings dam was built across the Ngamaboungou creek for the balance.

In 1985 COMUF started works to stabilize the course of the Ngamaboungou creek with rock, and to cover the tailings deposits formed in the valley along the creek with a layer of 30 - 50 cm compacted laterite. The tailings deposit in the former Mounana open pit was covered with broken rock and laterite soil. Contaminated areas at the processing site were covered with a layer of 0.7 metres minimum of lateritic soil. The rehabilitation work was completed in July 2004, at a total cost of €10.7 million including €7 million from EU funds.

At the end of 2013 Areva quoted 5420 tU at 0.027% inferred resources at the Bagombe deposit.

Gabon is party to the Nuclear Non-Proliferation Treaty and signed a safeguards agreement in 1979, but does not have a comprehensive safeguards treaty in force.

Guinea

Several companies are exploring for uranium in Guinea. In August 2007 the government noted that Murchison United NL, which became Forte Energy NL, had encountered some encouraging mineralization (or even "commercially viable deposits") at its Firawa prospect, 600 km east of the capital, Conakry. Forte announced 7400 tU JORC-compliant inferred resource at Firawa, with 1-2% rare earth elements present. In 2015 Forte Energy was delisted and its leases apparently lapsed.

Toro Energy and Contico also hold exploration licences.

Equatorial Guinea

The government has commenced airborne geophysical surveys to locate uranium mineralization, and has launched a new mining code.

Malawi

Paladin Energy, based in Perth, Australia, developed the Kayelekera uranium mine in northern Malawi, west of Karonga. Having produced about 4190 tU, the mine was placed on care and maintenance in May 2014. In March 2020 Paladin Energy completed the sale of its 85% interest in the mine to Lily Resources, a joint venture between Lotus Resources and Kayelekera Resources. The remaining 15% of the shares in the mine are held by Malawi's government. 

Lotus Resources (formerly Hylea Metals Ltd.) holds 76.5% of the shares in Lily Resources, with Kayelekera holding the remaining 23.5%.

In March 2020 Lotus announced an increase in JORC-compliant resources to 1580 tU measured resources, including run of mine stockpile, 10,445 tU indicated, and 2428 tU inferred, including a low-grade stockpile. The average grade overall is 0.053%U and the figures assume a 0.026%U cut-off.

The deposit was discovered by UK's CEGB and a feasibility study was subsequently undertaken in the 1980s. Paladin acquired the deposit in 1997, accepted a Bankable Feasibility Study early in 2007, and following environmental approval undertook a US$ 220 million mine development. The mine was opened in April 2009. Paladin (Africa) Ltd held Paladin's 85% interest following the Development Agreement with the Government of Malawi, and the government holds 15%.

The Livingstonia uranium deposit is in similar geology some 100 km southeast of Kayelekera, but as yet unquantified.

Mali

The Falea uranium deposit in southwestern Mali, 250 km west of Bamako, is being explored by Vancouver-based GoviEx Uranium. It was discovered by Cogema in the 1970s. This was formerly a project of Denison Mines, which acquired it through the takeover of Rockgate Capital Corporation in January 2014. Denison now owns 21% of GoviEx. There are three licences: Bala, Madini and Falea.

Uranium is envisaged as a co-product with copper and silver from Falea. Indicated resources (NI 43-101 compliant) are 8500 tU at an average grade of 0.1%U and inferred resources of 6200 tU at 0.06%U (2015). Mining would be underground. Radiometric sorting shows promise and several flowsheets are being considered to give three products. Original focus was on the central zone but in 2012 a further higher-grade north zone was identified. Mineralisation is in sandstones, mostly flat-lying, and the project is 20 km north of the Guinean border. A pre-feasibility study is envisaged after 2020.

Areva was exploring the Saraya East uranium deposit, 80 km from Falea.

Mauritania

Australia's Aura Energy has JORC-compliant measured and indicated resources of 6450 tU at 0.01%U, and inferred resources of 4580 tU at April 2018, with 100 ppm cut-off for its Tiris project. This comprises several tenements – one some 250 km west of the others, with shallow calcrete deposits on the Reguibat Craton in the north of the country, close to Algeria and Mali in the Sahara desert. The exploration target would double the resource. Hippolyte is the main eastern deposit and will be the plant location. In 2014 Aura announced positive results in beneficiating ore about sevenfold to concentrate fine carnotite, with tests showing rapid alkaline leaching. In 2017 the company said that the operating cost would be reduced by one-third due to metallurgical optimization, and in 2018 it was evaluating the feasibility of vanadium recovery as by-product.

The company applied for a mining lease in May 2017 and this was granted in December 2018 following an environmental and social impact assessment. A definitive feasibility study was completed in July 2019 for a simple truck and shovel mine up to 5 metres deep on the eastern deposit feeding a $45 million plant, with production at about 317 tU/yr from 2020, over 15 years. Production could be tripled subsequently. Good quality artesian water will come from 100 km away. In February 2016 Aura signed an agreement with Guangdong Power Engineering Co Ltd (GPEC) for engineering services and finance, the latter involving an offtake agreement for part of the production. GPEC is a subsidiary of CGN’s China Nuclear Power Engineering Group. The government holds a 15% interest in the project.

Forte Energy NL based in Australia in 2012 had prospects near Bir Moghrein in the north of the country near Western Sahara and at Bir En Nar nearby. In 2015 Forte Energy was delisted and its leases apparently lapsed.

Morocco

The government's Office National des Hydrocarbures et des Mines (ONHYM) is encouraging exploration for uranium to build upon that done by French and Russian geologists prior to 1982. Three areas are under investigation: Haute Moulouya, Wafagga and Sirwa. The first two have palaeochannel deposits. Toro Energy holds tenements in Haute Moulouya area.

In October 2007 Areva signed an agreement with Morocco's Office Cherifien des Phosphates (OCP) to investigate recovery of uranium from phosphoric acid. The amount of uranium in Morocco's phosphates is reported to be very large, and the feasibility of recovering uranium as a by-product of mining them is under active consideration. In 2007, 27 million tonnes were mined for fertilizer.

Morocco also controls Western Sahara to its south.

Nigeria

In March 2009 Russia signed a cooperation agreement with Nigeria, including provision for uranium exploration and mining in the country. A further broad agreement in June 2009 envisaged the construction of a Russian power reactor and a new research reactor. See also Emerging Nuclear Countries paper.

Tanzania

Several companies are exploring for uranium in Tanzania.

Uranium One is undertaking a definitive feasibility study for its Mkuju River project in the Namtumbo district of southern Tanzania, incorporating the Nyota deposit which is the main part of it, 470 km southwest of Dar es Salaam. Government environmental and other approvals are well advanced and Mantra Tanzania Ltd was granted a Special Mining Licence for the project in April 2013. The government has allocated 345 km2 of land inside the 50,000 km2 world heritage Selous Game Reserve to the project – 0.7% of its area – and with hypothecation of some $5 million per year of mine taxes (ten times the Reserve’s present budget) to its management, along with investing US$800,000 in anti-poaching activities. The UNESCO World Heritage Committee in July 2012 had accepted the Tanzanian government request to excise the area required for mining.

Uranium One expected to start mining in 2013, eventually producing 1400 tU/yr, but has suspended the project due to low uranium prices. CIM-compliant resources are 58,620 tU, including measured and indicated resources of 48,000 tU and inferred resources of 10,600 tU with average grade 0.026%U at 100 ppm cut-off (March 2013). Proven and probable reserves early in 2016 were quoted at 25,876 tU at 0.041%U. The resources are extensive, in sandstone at shallow depths, and present plans are to mine in multiple pits feeding a single mill with conventional acid leach and resin in pulp recovery. ISL mining using acid may be employed, especially for the 13% of resources outside designed pits and also below the water table. One-third of the total resource is below the water table, so the ISL potential could be greater, and the company early in 2016 was actively considering this. Capital costs were estimated at US$ 430 million for the treatment plant and infrastructure, open pit mining would be contracted. Cash cost is $25/lb for conventional mining but overall cost will be over $50/lb U3O8. A preliminary feasibility study on heap leaching lower grade ore as phase 2 of the project was under way, and results look very promising.

The project was commenced by Australia's Mantra Resources, which was taken over by ARMZ in mid-2011 for $1.16 billion, allowing Uranium One (then 51% owned by ARMZ, now wholly owned) to take over development of the Mkuju River project and other exploration activities. The Tanzanian government was claiming $196 million in capital gains tax from ARMZ, plus $9.8 million in stamp duty.

In the south, close to Uranium One's Mkuju River project and with similar geology, Australia's Uranex NL was developing its Mkuju Uranium project, with Likuyu North and other deposits which have significant mineralisation. A mineral resource estimate for Likuyu North in 2012 suggested about 2350 tU. In central Tanzania some 80 km west of Dodoma and adjacent to its Bahi deposit, Uranex in 2010 reported inferred resources of 12,000 tU in a shallow deposit at Manyoni, which it hoped to mine in 2013. The Itigi prospect is 50 km west of Manyoni. Mining approval for Bahi was given by the government in 2009. In 2014 Uranex suspended its uranium developments and turned to graphite, focused on its Nachu deposit, and it changed its name to Magnis Resources.

In the south-east, East Africa Resources based in Perth was investigating its Madaba-Mkuju sandstone roll-front deposits, originally discovered in 1978. In December 2011 Korea Resources (KORES) agreed to invest $3.5 million for a 50% stake in the Mkuju South project. In  2015 the company exited uranium exploration and merged with Threat Protect Australia.

US-based Uranium Resources Inc (URI) in May 2013 announced inferred resources of 770 tU for its Mtonya project in southwestern Tanzania, most of which is potentially an ISL operation in similar geology to Uranium One’s Nyota deposit and 60 km south of it. URI subsidiary Uranium Resources PLC (URA) manages the project. Drilling was undertaken in 2010, but as of mid-2017 no resource data had been published.

Tanzania-based Kibo Mining entered into an agreement with Metal Tiger regarding a 50/50 joint venture on its subsidiary Kibo Uranium’s Pinewood uranium-coal tenements near Songea in southern Tanzania. Metal Tiger was farming into 50% of Kibo Uranium for $800,000 over three years from early 2015, but in February 2017 Kibo relinquished its licences over the deposit.

The government announced a new uranium mining law to be put in place in November 2010 to assist diversification of its mining sector. It quoted known resources of 21,000 tU at the above sites.

In July 2017 a radical new mining law came into effect requiring the government to own at least 16% of projects, and increased royalties. The president announced that no new mining licences would be issued until Tanzania "puts things in order" and that the government would review all existing mining licences with foreign investors. The changes seem focused on gold.

Zambia

GoviEx Uranium Inc of Canada is planning to develop its US$ 118 million Mutanga uranium project in southern Zambia, close to the Zimbabwe border, when uranium prices improve beyond $65/lb. This was previously being developed by Denison, which announced a NI 43-101-compliant resource in March 2009, based on shallow orebodies: Mutanga, Dibwe and Dibwe East. Following successful licence renewal, a feasibility study was undertaken for an open pit mine with acid heap leaching, producing at $38/lb U3O8. The project has two contiguous 25-year mining licences, environmental approval and radioactive materials licence. The Mutanga pit would be 750x550 m and the Dibwe pit 10 km southwest would be 1500x300 m. First production is envisaged in 2023. The project, formerly known as Kariba, was developed by OmegaCorp prior to its acquisition by Denison and then GoviEx.

The Chirundu project also close to the Zimbabwe border comprises the Njame and Gwabe deposits and has 2850 tU as measured and indicated resources, with 1460 tU inferred (mid-2017). A mining licence was granted for the project in October 2009, with a view to a 500 tU/yr acid heap leach operation. It includes the Siamboka prospect. A feasibility study was commenced but then deferred due to low prices. The company was also exploring the Kariba Valley/Chisebuka prospect 250 km along strike southwest, on the other side of the Mutanga mining licence tenements. African Energy Resources originally held these deposits but in 2017 sold the whole Chirundu project and Kariba Valley tenements including the Chirundu mining licence to GoviEx, giving it almost contiguous tenements of approximately 140 km in strike length parallel with the border, including three contiguous mining permits. The combined mineral resources are 5800 tU measured and indicated resources at 0.028%U and 17,400 tU inferred resources at 0.025%U (Nov 2017) for its Mutanga project including the Chirundu deposits.

GoviEx also bought the Northern Luangwa Valley project in northern Zambia from African Energy Resources, including the Sitwe North prospect where the uranium mineralisation occurs in multiple horizons and is open in all directions.

Equinox Minerals, based in Perth, Australia, is operating the US$ 762 million Lumwana project in NW Zambia. This is primarily a large copper mine, with two open pits 7 km apart. In 2010 it produced 146,690 tonnes of copper. Following a bankable feasibility study on uranium recovery the company announced 3800 tU indicated resources at 0.079%U and 2570 tU in inferred resources. The uranium is in discrete uranium-enriched zones that are being mined separately from the copper ore and stockpiled. An environmental impact assessment of the uranium project was approved in December 2008 and treatment of uranium ore to produce 700 tU/yr was planned from 2010. However, investment in the $230 million uranium mill was deferred due to low prices and difficulty in financing this part of the project. The Malundwe open pit is the first of two uranium sources within the overall project, where the mineral is in discrete veins in the broader copper mineralisation. In January 2011 the company said that it had 4.6 million tonnes of uranium ore stockpiled containing 0.09% uranium and 0.8% copper. "This uranium-copper stockpile may be treated at a later date, if and when the Company builds a uranium plant." Meanwhile it is being classified and expensed as "waste" to the copper project. In mid 2011 Equinox was taken over by Barrick Gold Corp. for C$ 7.3 billion, in the face of a rival bid from China Minmetals.

Zambia has upgraded its mining legislation to take in uranium, following detailed consultation with the IAEA. It started issuing uranium mining licences late in 2008, and in 2017 was undertaking a further revision of regulations regarding uranium exploration and mining. It is a signatory to the NPT and has been a member of the IAEA since 1969.

Zimbabwe

The 2018 Red Book notes 1400 tU as reasonably assured resources recoverable in the $130-260/kg bracket, and also speculative resources of 25,000 tU. Other reports mention a deposit at Kanyemba, north of Harare, in which Iran has expressed some interest.

While doing a sub millimeter study of the shocked, splattered fossil I noticed that the cold rolled steel millimeter rule has the shock Septarian effect. It was rolled at around 1 GPa over and over. So the shock waves not in contact are able to produce this effect from distance as a traveling force. While the etched matte finish of the rule is producing a prism rainbow effect the specimen has imparted nano color. The average size of the chromatic nanoparticles can be controlled from 230 to 310 nm That is millionth of millimeters. An atom is a million times smaller than the thickest human hair. The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 × 10−10 m to 5 × 10−10 m). I keep finding smaller and smaller shock effects which is supporting even an atomic effect to impact events. 
1024px-Trinitite-detail2.jpg
Trinitite shown above from the Nevada dessert. Although the blast is thought to be as low as 13 GPa but higher heat than impact explosions, the impact glass shows venting holes from gas/vaporization effects. It also has particle inclusions. While atomic explosions are not thought of as kinetic events the explosion is precipitated by a chemical explosion percussive fuse that smashes the unstable elements together fracturing the atom. Now think about a meteor traveling through celestial space colliding with exploding stars and unstable debris forms then smashing into earth at cosmic speed 30 + miles per second. The meteor could contain exotic elements highly unstable who knows if we even know of them all and this compression on impact is the true first atomic explosion on earth. 

The Meta Mining Game - You can take geology reports that cost the government a lot of money back in the day and get a great understanding of geology misunderstanding. I play "pick a page" sometimes. I have read through this big report already but sometime any page will show what they did not know and still don't know. Let's get started.

So in the picture you can see what I call "thin plane insertion" of uranium. That is a fractal plasma stream like lighting shot out at hyper velocities in an impact explosion. In the chart above you can see the term "unconformity." That is better termed "wiping event." It is an impact blast that occurred at that strata point. 

The term Oolitic Limestone is a common misconception in geology. They somehow postulate it as circles that just appear. They are in fact spheroids produced in an impact explosion. Liquid explosion drops. Of course this is a physics much greater than is taught in geology or physics for that matter. Impact is a progressive event. The shock spheroids were formed and the uranium plasma some micro seconds later bisects the sphere. The matrix was in a shock liquid/plasma state. Additionally the Oolite contains fiber crystals and particles from the shock particle storm. The fractal fiber crystals are forming septarian forms.

From Morocco. Here we have dendrites a shock made form on Vanadinite a radioactive mineral source. Same rock, can't help but be from the meteor.

Of course you can have compression alteration of minerals. That is how the first atomic bombs were constructed and it worked of course. Now consider how much greater the compression alteration is from a celestial impact. These kind of pressures are not reproducible in laboratories they are so high. Now also consider the picture below and it's curious implications. If you posted it on line for identification I dare say you would have agreement it is a petrified tree stump. It is in fact a large "shatter cone." Shatter cones are no one particular size. As all impacts are unique shatter cones are as well. While most geology as practiced in 2020 is largely unaware of impacts as a science the amount of unidintified and misidentified geology is so large as to render geology a malpractice akin to medicine in the four body humors era, which lasted for 2,500 years and also claimed to be a science. It is a historical fact that your health prospects were better without the quack doctors in that age and the same is true for geology, most of it is so wrong as to be dangerous. If you pull up the USGS map of the lake where I live which is dated in the 1970's you will see no lake although the lake has been here since the 1950's. Did they just keep using a very old map? Yes, and was there any geological understanding of the dam construction, no. And that is true to this day. The lake leaks by the way.

ANALYSIS

Mining the world’s rarest mineral in meteor craters

SHARE

An ultra-rare mineral named reidite has been found in what is possibly the world’s largest crater at Shark Bay in Western Australia. The crater is only the sixth-known on Earth to hold the mineral, which starts as common zircon before transforming to reidite under the pressure of space rocks slamming into the Earth’s crust.

Around 360 million years ago, in what is now Western Australia, a meteorite crashed to Earth, creating a crater some 120km wide. Now known as the Woodleigh crater, it sits in Shark Bay and is potentially the biggest crater in the world.

Despite geological examination in the 1990s and 2000s, the incredibly rare mineral reidite was discovered just last year in Woodleigh. This is only the sixth time it has ever been discovered on Earth, as it requires very exacting circumstances to be created, and it is rarely looked for.

“Reidite is so rare that one doesn’t ‘set out’ to look for it – the chances of finding it are slim,” explains Aaron Cavosie, Curtin’s School of Earth and Planetary Sciences research supervisor. “One of my Honours students, Ms. Morgan Cox, decided that it was worth it to take a look at zircon grains in the Woodleigh core, and so we requested core samples to study. We were expecting just to find damaged zircons, not reidite. Finding reidite really blew our hair back – it was a serendipitous find.”

An accidental discovery

Given the length of time between the impact and current studies, it is hard to understand the full impact of the meteorite that caused the Woodleigh crater.

“The time period is called the Devonian, and Earth was quite different back then,” says Cavosie. “Plants had just started to colonise land surfaces, and sharks ruled the seas. The impact could have caused giant tsunamis if it hit in a shallow marine environment. If it hit entirely on land, it could have caused global climate shifts.”

The impact was so powerful it changed the landscape and the geology, creating reidite out of zircon, which is commonly found across the world. It is an alteration that could not happen without a meteorite.

“Impact events create crushing pressures in Earth’s surface that do not naturally occur under any other circumstance,” says Cavosie. “The pressures to form reidite – ~300,000 atm of pressure, or ~30 Gigapascals – cause the atoms in zircon to re-arrange into a tighter arrangement. Imagine having a packed room full off 25 people, and then suddenly shoving 25 more people in the same room – they are packed in a lot closer together. This is what happens to the atoms in zircon – this process causes it to recrystallize into the high-pressure mineral reidite.” 

In 1999, investigatory work began on the Woodleigh crater by the Geological Survey of Western Australia. It drilled into the rock examining, amongst other things, the shock metamorphism of minerals. At the time however, given its rarity, reidite was not looked for and studies stopped after just a few years.

“Reidite has only been found from six impact structures on Earth, and Woodleigh represents the first time it has been found in Australia,” says Cavosie. “All of the naturally occurring reidite that has ever been reported could probably fit under your thumbnail, so there isn’t that much.”

A controversy arose over the size of the crater during these studies, eventually drawing attention to other aspects such as minerology. “One camp interpreted the data to mean the structure was ~40km-60 km in diameter, the other favoured a size of ~120km diameter,” says Cavosie. “In other words, there was a big disagreement among the early researchers.”

“Our find of reidite, and its occurrence in the lower section of the drill core, supports the interpretation that the crater was larger than 100km,” he adds.

Could meteor sites be mined?

While the discovery of reidite is interesting and important from a geological point of view, how practically useful it is, is another question. This is partly due to the incredibly small amount of what has been found and the difficulties of creating synthetic reidite.

“It has been synthesised in the laboratory using different types of high-pressure instruments, but it’s not easy to make in bulk,” says Cavosie. “Much is known about the crystal structure, but there are other things to explore, such as if it can be used to date impact events. We’re working on this, but it’s tricky, given the limited material.”

Both when it naturally occurs due to extreme pressure caused by meteors and when synthetically created, the base of reidite is zircon. This is a gemstone that occurs in a number of colours and has been popular predominantly for decorative purposes for 2,000 years. It is also the primary ore used to make Zirconium, which is added to metals to make them heat and corrosion resistant.

“Reidite is 10% denser than zircon, and so it has a high specific gravity,” says Cavosie. “Zirconium is used as a refractory, and reidite has the same chemical composition as zircon, so in principle, there could be material applications.”

Therefore, reidite could be used for many of the purposes that zircon currently is. It is also technically possible to mine within craters, and there are operations around the world currently taking advantage of the mineral wealth within these sites. However, it is unlikely that reidite will ever be commercially mined, in Woodleigh crater or elsewhere, due to its scarcity.

“Large impact craters in South Africa and Canada are mined for gold and nickel, but reidite is probably not economic enough and in a high enough abundance to represent a target worth pursuing, unless someone discovers something special about it,” says Cavosie.

But the importance of the discovery goes beyond mining prospects, giving us a glimpse into history, mineralogy and Earth’s relationship with space.

“Reidite is incredibly rare, and when it is found it is always associated with a cataclysm from space,” says Cavosie. “In principle it could occur in Earth’s mantle, however many zircons have been recovered from the mantle and reidite has never been reported. So when it is found, it symbolises violence from space.

“Some impact events are minor occurrences, whereas others have profound implications for life, such as the impact in Mexico 65 million years ago, that resulted in the extinction of the dinosaurs, and the rise of mammals (us!). That’s a big deal.”

Now this is interesting. Shown above is Ishikawaite from Japan. (U,Fe,Y,Ca)(Nb,Ta)O4 (?) Now take a look at the specimen below from The Spinelli prospect, located in Glastonbury, Hartford County, Connecticut, USA.(John Betts Fine Minerals)  So above you have shock Septarian forms and below you have a sign wave, constellationing, fractals, and triangle wave. These are Impactites.

The Central TN radon is from the Howell Impact. It was stopped by the walls of the previous Middle TN Basin Buster which made the Highland Rims but since it hit in the lower crater wall rim the old crater is distorted but did allow the radioactive debris to shoot straight up through the middle of the large crater to the north crater wall Highland Rim. NE edge is distorted by some smaller impacts. East TN is a much larger event.

Radioactive Minerals and Objects

Just finished caving for about 9 hours in a Tennessee cave near Sparta. I recently got a Geiger counter, and I brought it into its first cave. Background levels were up around 300-600 CPM throughout most of the whole cave, especially the deeper we went.

However, I started placing it on our gear and clothes after a particularly long crawl where we were covered in dust and all of our gear were over 1000 CPM. Should we be concerned and can we “wash” it off? Is this normal for caves in this area as well?

This corresponds to the Strontium Crater shown above and the Sparta Crater. An impact like the Sparta crate can spread the radioactive particles widely. March 11, 2024. 

Shatter cones and variants. The stream has excavated down to the "shock floor." The pink is the impact iron mist that bond to impactites (a plasma late stage fallout.) Coning is a shock wave form set up as a sine wave, however this shock floor has variants with concave cones and cross striations. While the NW and SW state has some big old craters as shown on the geology anomaly mapping the central state is radioactive. Like meteorites the large earth impacts vary in meteor/bolide minerals. Even though later geological events alter the original crater like a glacier flow these minerals are embedded throughout the original crater area. You can still see this large crater on the uranium map. June 25, 2024.
