Petersburg, TN Mega Clast Mosaic Surfacing. Unlike chemical or nuclear bombs, heat is not a primary energy of an impact, shock is. But heat is a product of so much shock compression and expansion friction. The sea was blasted out of the crater and then came back in, quenching very hot semi-liquid material.
Heat mosaic bricking is not a common phenomenon. It is a fractal by nature.

Consider the picture below. For this to be a sedimentary rock it must be oriented as shown since the "sun baked it's surface." Yet is also claimed to have worm fossils. So that entire block would have to be made concurrently because the "fossils" overlap vertically. That is not sediment since it is only one layer. Logic problems are many here. Why would all the worms point vertically? These are not voids but thin quartz alignments. Worms make poor fossils, yet all these are distinct. This is easier explained as shock aligned and quenched.
Shown below is a type of Shock Septarian Mosaic heat shrinking. This is the only specimen of it's type I am aware of. It is from the off shore San Clemente, CA impacts and was found shoreside in a canyon. You can read about the San Clemente Impacts at: https://academic.oup.com/gji/article/159/2/803/2067497?fbclid=IwAR0a2_15nlxpuGvMbgFYuI6r0SJcbYUXy8u96K40r-_I7sXAldFBnLQka8I
Shown below is a specimen from Midlothian, TX USA This surface was very hot. The amount of space in between the mosaic represents evaporation. The black of course is iron oxide. You can also see the granular particles that make up the shock particle storm from large earth impacts. It is my belief that these small size uniform particles represent distance for the particles to sort into a uniform size away from the impact center. A rock this size can also be kicked a long distance. The original Texas kicker.

Shown above is an unknown surface effect as shown on the bottom of a dry lake bed in California. It could be a shock type of Mosaic Surface.

Shock Hieroglyphs - This is a surface type of Mosaic effect that does not crinkle very deeply. It was found on a bolder near Pearl City, TN.
Blast Crevasse is not the same as impact Mosaic. The blast crevasse is formed by a shock particle impact storm and is therefore not a heat surface cooling effect. The bolder is from the Washington State Park Missouri Impact Structure.
Interesting impactite with a cooling surface which made voids and drying marks. It has a slight dark matrix Fe3O4 the white shock particle storm inclusion matrix.
The mosaic pattern is heat cracking but depending on how hot and the total mass it can crack the whole rock. This one almost is. Has a slight iron mist surface which came from the meteor.
A Sequence Mosaic - Follow the crack shown left and you will see a Linear Constellationing Particle stream crossing it. Specimen from Lake Logan, TN Dam.
Specimen from central Alabama. Linear mosaic. Cracking from heat like wrinkles based on the stress relief in the material. It is interesting that on a larger scale you see this sometimes in mountain rock exposures.
The green is shock olivine. The surface is the shock constellationing particle storm. It is building a heat dispersing network. A type of mosaic. Specimen from Hatice Yüce
Classic Mosaic Pattern - Magnified you can see the granular particles forming circles. That is a shock resonate effect. This is an impactite. It would be called a mudstone that cracked when dried to anybody who does not understand shock particle theory. Specimen from نيازك تنجداد كشتام
Impact sphere from the Wetumpka Alabama Crater. It has heat mosaic cracking. Specimen collected by Jennifer Collier Simpson
The septarian mosaic solution to heat exchange as an energy signature may represent the most efficient heat exchange solution.
Square crystal polymorph shock harmonic - This is a rare shock made figure, a compressed bubble form. It is from an earth crust breaking impact centered near Winston County. Specimen collected by Savannah Whisnant of Gadsden, AL. While not a true heat exchanging mosaic as it's origin, it does have the same property of cooling surface. This is commonly called boxwork.
Double shock mosaic - I think this may have been shocked Silurian strata which was reshocked by the Frankewing Impact. It makes an effect I call a pancake mosaic. It also contains thin plane insert high energy quartz tree fractals. This is not a slow fill by deposit, it is the opposite, a lightning type of energy dispersal.

Mosaic Fizzing Surface - This high shock megaclast was located between Huntland, TN and Skyline, AL, it shows a very high suface evaporation heat. The fizzing evaporation also makes Turing Pattern sequence.
I first thought this to be a mosaic heat cracking around an inclusion. On closer examination I noticed it was so hot the central surface cracked and fell off. Johnson Top Madison County, AL. This is located on the otter crater wall of the Howell Impact in Tennessee. The Howell Impact landed in a previous large crater wall the Highland Rim lower section and pushed it out into North Alabama.
Notice the Mars Impactite below was hotter. I suspect the specimen above was quenched by rain or on rushing sea back into the crater.
Wopmay in False Color .
NASA's Mars Exploration Rover Opportunity examined a boulder called Wopmay before heading further east inside Endurance Crater. The frames combined into this false-color view were taken by Opportunity's panoramic camera during the rover's 251st martian day (Oct. 7, 2004). The coloring accentuates iron-rich spherical concretions as bluish dots embedded in the rock and on the ground around it. The rock is about one meter (3 feet) across. Credit: NASA/JPL/Cornell

Scatter mosaic with hole and linear cavitation.
High heat surface melt impactite evaporative mosaic shown on top left. I think it was once part of a lower strata blasted from the Chesapeake Bay Impact. It has various mineral pressure heat combinations from the powerful explosion which imparts some of the meteor's own minerals. Found in Central Pennsylvania by Cory Lucas.
Shock melt very high heat and column expansion. This is beyond typical heat mosaic. This specimen was in a partial evaporation sequence. Susan Imler specimen.
Oblate Mellon Mosaic - Impact nodule with heat mosaic surfaces. Likely from Wells Creek Impact. These nodules are the lowest strata in the impact crater splashed outward for many crater distances as basically a hot liquid/plasma drop.
Lives in McEwen, Tennessee
Mosaic cross - this is a final effect a stress reaction to release heat most effectively.
Linear mosaic impactite from Chesapeake Bay Impact. Why linear? Why tubular? First linear implies a consistency that would cause cooling breaks in a uniform heat relief way. Also the tube form is conducive to stretch breaking. Alas the striation cracks are not exactly uniform which is normal. The tubes are coning wave structures. Impact makes shockwaves and these are many frequencies including the triangle sine wave form. Magnified in the upper section you can see a fiber crystal. These are shredded matter. Landing on specimens in a hot plasma state and bonding. Uncommon specimen collected by:

It’s not a flower, and it’s not in Colorado. I stopped in the Bisti wilderness of New Mexico holding back from Colorado and taking a photo there. I wasn’t there a few years ago and my photography was the last time I visited. I was glad I got this recording this time (yes, it’s on the ground). It’s amazing what happens to these rocks after the sun goes down - they get amazing light

Found: Eastern Oregon.
Splatterform geometric mosaic - You are seeing a freeze frame in time of an impactite sequence effect. The core nodule was splashed with the melted sand/silica involved in the impact site. It was so hot that it wrapped the core nodule and cooled pulling it into the wrapped net mosaic. It is a very nice specimen.

Not found in MN but thought I'd share as it was a cool fossil. Delete if not ok...found in Indiana river rock.
Isolation mosaic - not just cracks but quartz filled cracks. This heat has refined the quartz out, 5,000 degrees F. Vague cobalt composition. It was once bedrock impact ejecta, a relic from a big earth impact, usually a type 3 exploding type. Type 1 earth accretion are absorbed into the earth and make the earth bigger causing expansions of the crust like the separation of Africa and South America. Type 2 subduction craters come in at angle and uplift mountains and make crust faults. Type 4 do not explode.
Douglas Lake Impact Crater Impact nodule with high heat mosaic shrinkage. An excellent find. These bits and pieces are thrown out as ejecta in a plasma condition then cool, some crack and some shrink as a mosaic condition. Hope you don't mind but I need to add and share your post as it represents an illustration teaching example.

Mosaic Breccia
<Granular fractal
Late arriving inclusion with iron
Inclusion mosaic cross
The inclusion is a late arriving impalement, as is the iron surrounding it. Left of that is its most interesting feature, mosaic breccia. Above the inclusion if magnified you can see upward granular fractals. Right side is an inclusion that made an x mosaic. The matrix is milky quartz in a high shock.
Impactite, Septarian fade sequence mosaic. It is cooling by mass, therefore the mosaic pattern is changing.
Impactite, silica iron oblate sphere, with high heat mosaic and outward radiating points (very very rare feature), thin plane iron insertions, and possible fiber crystals. So what does all that mean? Well first of all the tektite definition was not far off. Is not a fossil or meteorite. While I live in a very powerful impact structure it did not make any of these, so lets figure the source of this specimen was a larger crater say 100 miles diameter up. It was a close in orogeny to have sustained this much energy. It is also very old. I would think early Devonian and before for the iron to weather away this much. The color is high silica with black iron oxide as a nano particle. Nano pulverization is a product of the great energy involved and the iron is from the impacting bolide. Finally as specimens can attract hairs it is difficult to tell if you have a fiber crystal on surface. Fiber crystals are a shredded matter not dissimilar to thin plane insertion i.e. shredded matter. It is the same phenomenon as Pele hair.
Mosaic surfaces of this nature are from a very high resonance energy which is gassing this specimen from the center towards the surface radially.
Phillip Corey Denton
Anyone have a clue as to what this is? I got it and was told it’s a meteorite, also been told it’s a tektite, and lastly a piece of obsidian. It is semi-translucent and about 2lbs( which is larger than tektites typically are.
Impactite, Botryoidal, Fractal, Mosaic, High Iron Content - Energy sequence directionality shows the bubbling, then the larger fractal to small fractal all of which are energy dissipation forms. Tim Williams specimen is from the Howell, TN Impact and while similar has less energy, so lets figure your specimen came from a larger impact of a 100 mile crater up.

Anthony Schmid specimen.
This is an impactite from one of the big Oregon Craters. Yes the center is a chert type, however the outer rock is a bubbling quartz. It's most interesting feature is a second order energy tree fractal mosaic surface. Very Rare! So what is a second order tree fractal? A fractal energy form will branch when it exceeds its quanta bracket form. In other words it will keep making an energy trunk unless it has too much energy or too little energy as energy has a form that matches its quanta power state. Horizontal branching is a second order where the energy is so strong it must start a series of new sub branching each independent of the main trunk branch length structure. This energy was made in the shock chaos storm of turbulent nano particles swirling at very high speeds generating electric charge like a volcano does. A volcano will make lightning in its cloud up to 10,000 times the water vapor clouds propensity. The tube on the right is a collapsed bubble tube. The colors are nano cobalt and iron from the impacting bolide/meteor.

Heat made rejection patterns not resonate. While it was able to blend some nano iron the surface shows not mixing (rejection) going on.
Shock white impactite, botryoidal, mosaic splitting. Shane Vaughn specimen.
Slag or impact splatterform? If it is slag it will have some provenance of dumping or an industrial site near. I rather think it is a splatterform, quartz olivine melt. It also has a round bead present as in more melt type attachment. The crackle glaze mosaic septarian is also seen in ceramics.

High heat mosaic bricking, fractals shown left side and crossing planar features.
Bricking is not normal for mosaic surfaces as they are a fractal like the one in front. The bricking mosaic is following the bricking imprint laid down by the cross planar shock. The fractal left is thought to be a petroglyph, but is a long fractal energy signature. Remember this is a crater that has Iceland as a central uplift so this energy is at a scale much larger than the smaller craters. Sept. 4, 2023.

Impactite, surface high heat Septarian mosaic with resonate shock circles and mineral separation. RARE. Valuable like a gemstone. the matrix shifted to higher black iron oxide during forming. Very how and cracked while cooling the surface mosaic. The shock impact that made it separated minerals by resonance which also makes circles. March 5, 2024. Amon Montgomery specimen.
Impact sphere with impact sphere impalement and high heat mosaic and delamination. It is from the Big MO Impact which takes up most of the state from the SE outward. The iron etc. is from the impacting bolide. It was the limestone strata where hit which was liquified and expelled. The delamination is in a higher heat facing side that over cooked it whereas mosaic is simple cracking. Squares are rare with mosaic cracks they generally crack as fractals that overlap or circular that press against each other forming polygons. These pushed up and against each other more uniformly. March 5, 2024. Coral Cranmer, specimen.
David Buthman Information theory - after many hard knocks with rocks I have to use information theory with look alike rocks. The coral fossil will have Too Much Information i.e. too many levels of complexity for a physics form to make. In the case of this specimen it is too little information for coral. This is a type of heat mosaic expansion, compressing bubbles similar to column basalt. The rock was so hot it has isolated the quartz on the surface in a mosaic expansion. Coral fossils attached with the multi level repeating forms. Three levels of forms is always a candidate for fossil which has DNA information. March 15, 2024.

Earth impact nodule, impactite, various high heat mosaic patterns and flow fractals. It may contain sulfur. So how does this happen. A large meteor/bolide hits earth like the one in Arizona. It and pieces of the earth are shock liquified and ejected outward. The sulfur would have come from the meteor. Impact melt objects are not meteorites, they become impactites if melted and reformed.

Mosaic fingering - You usually see this in blast surface strata, seeing this as a specimen is rare, so this may have slabbed off. So why not a more typical mosaic pattern? This type of mosaic cracking comes from an edge and simply satisfies the heat cracking stress by going from the edge linearly inward. May 31, 2024. From Lower California/Baja Impact. Steven Cole Specimen.
Rejection Pattern Mosaic - Two factor physics in play here. One is the typology of rejection patterns i.e. surface not mixing with environment, like paint color added to a can of paint base. This pattern is the more classic "Turing Type Pattern." It is also the surface wrinkling as the stone cooled. It is from the lower California/Baja Impact and found by Steven Cole.

Hi ya’ll! I appreciate that this group allows ID requests from people with strong MI connections -EVEN when the specimen was not found in MI. I live between Light house beach and Pier cove ( to speak your love language ) I reciently traveled to Northern CA, I asked people in the Northern CA rock hound groups for help ID;ing this lumpy thing but the best I got from them was Avocapoo -lol! It is So different from all the colorful jasper, granite, jadite, agate, nephrite, serpentine I was finding it stuck out like an avocado in a fruit bowl! I dont recall what beach i found it at but it was one of the ones i went to near Jenner where the Russian river meets the ocean, I was on the ocean beaches… not river bank. So here I am asking if any of you know #pleaseidentify. The photos with the sharpie are wet, the last is dry. It is very hard, not magnetic and weights 312 grams and is approx 3.5” L x 2.5” W x 1.5“ D- thanks !! -
Impactite. The surface is a fractal mosaic which is not common. It has direction with the trunk of the fractal being the source of the energy direction and the branching the direction of flow. Quartzite was once sand. Surface color is due to iron blasted out as a mist forming black iron oxide and some red, the mosaic splitting occurred thereafter. In magnification you can see the development of thin line quartz fractals forming fiber crystals. Fiber crystals are shredded matter like found in Hawaii called Pele Hair but your specimen is in the proto process stage of forming these thin structures. The QLD southeast crater complex is shown on the attached map with the two nested craters in the much larger older crater. The bigger two are the prime suspects as this took a whole lot of energy.

Impactite or meteorite. The surface is ablation with high heat mosaic separation. In the cleavage plane inside you can see very narrow coning which is its formation showing a directional origin. That favors impactite as a liquid oblate drop. The surface shows some directional cavitation like meteorites. Tektites can be launched into lower space and return btw. So can impactites which tektites are a type of. I really like this specimen. It is interesting. July 29, 2024.
I found this recently in a river near my town in central British Columbia. I've been trying to find an accurate identification. The closest id I can find is a tectite. I'm planning on taking it to a mining company this week to see if they can do some tests on it and give me a clue. I waited a couple weeks and then we gave in to curiosity and cut it. We cut it with a diamond blade on a chop saw most of the way through and then used a chisel and hammer to break it the rest of the way. Any thoughts?

My friend found this rock. Any ideas? Just outside Tonapah, Nevada.
Impact sphere. Tektites are a sub class of impact spheres. Surface mosaic/rejection patterning. The surface forms are not directional, therefore this is not an earth entry ablative skin. This surface is a type of rejection pattern/ablation high heat mosaic effect. It is a cusp of both physics. While high heat mosaic surfaces are the most understood the physics of rejection patterns is not. First let's start with the most common. When color is added to the paint bucket it is unmixed and will require energy to mix it. A specific type of energy by vibrating it. The next most understood type is "Turing Patterns" (Alan Turing, 1952). While this specimen is not a typical Turing type it is close. Turing patterns are a sub class rejection pattern of the over arching group "Constellationing." Sept. 29, 2024.
