Crisson Gold Mine in Dahlonega, GA
Woodbury to Manchester Structure could be as old as 900mya. >>>>>
Shown above is a gold nugget from Crisson Gold Mine in Dahlonega, GA. Notice the fractal energy forms going from bottom to top. That is energy directional.
Georgia Gold Belt. March 2, 2025.
Quarry at Graves Mountain, Lincolnton, GA - While a volcanic process can make this, it is also a suspect impact energy strata. Large boulders impale the upward strata. Ash in foreground. And of course the iron. Iron does not occur as a mist in a volcanic eruption. A close up inspection of this site would tell a lot about mechanism.
Dexter Craig of the Knoxville Gem and Mineral Society shock made agate from James H. Sloppy Floyd State Park near Summerville, Georgia. The matrix surface exposed in the vugs show a shock constellationing pattern of squares and circles. The black dots are late arriving micro impact sphere type particles separated in the shock chaos storm. Iron present is the atomized meteor in the shock wave.

I need to add this to my on-line encyclopedia of phenomena if you don't mind. Shock made mega clast with iron splatterform expansion constrained bubble from. Late arriving iron from the impacting bolide with very high heat making this two dimensional geometric form. You can see this with a bubble wand as the bubble surfaces will press against each other making geometric forms. Note the lower section as a less iron fractal inclusion which arrived before the higher iron splatterform.

My buddy picked this up at a rock yard in GA, it was mined locally. They used it to hold down a huge tarp, but let him buy it.
I was told this is called "iron boxwork formation".
Never seen anything like it...
Impact clast type 2 high heat slow cool. The blue is likely cobalt. A type 2 impactite is part surface part meteor mix. This is part of the bedrock strata highly shock modified metamorphic. When magnified the vug contains thin fractal quarts surface veins. These are fiber crystals a phenomena like volcanic Pele Hair. They arrive late in the impact event as shredded matter.

This specimen was found further inland than is typical. Ordivician types have been found in middle, TN. As recent as 19,000 years ago there was a late flooding period with the sea reaching all the way up into southern AK with not fossilized shells present in the sand deposits. See attached map. July 8, 2024.

Found in Madison, GA.
Madison, GA. As it only takes 10,000 years to make a fossil I think the data on the inland sea of Georgia should be reconsidered. July 7, 2024.
Impact made blast crevasses. These impressions point towards the center of an impact. It is highly likely that the boulder was in a simi liquid state as the blast occurred. The gravity map of Georgia shows several impact craters. Aug. 30, 2024.

Impact sphere gas bubble collapse implosion. You see this variant shape physics with plasma/gas. As it is also ejected at speed from a kinetic explosion the collapse has a motion component. Without motion, the physics is explained in this technical article. Sept. 20, 2024.

The Evolution of a Gas Bubble Near an Inclined Wall
​
-
Jul 1998
The nonlinear dynamics of a gas bubble close to an inclined wall is investigated numerically. The fluid is assumed to be inviscid and incompressible and the flow irrotational. A time-integration boundary integral method is used to solve the Laplace equation for the velocity potential to calculate the shape and position of the bubble.

It is also one of the tektite sphere deformation shapes, From sphere to disk. Sept. 20, 2024.
Polk County, GA
While it is likely the sphere, i.e. a liquid drop is the origin off disk and tubular impactites, the flow drag as ejected from the kinetic explosion has a shaping effect cycle. It is something like the lava lamp blob shapes that keep changing shape. Sept. 20, 2024. Chart is from this article.

The internal inspections of some submerged structures require the use of remote operated underwater vehicles. However, such kinds of vehicles demand power, handling, and resilience characteristics in order to work properly without compromising its structure and its internal components.
Impact sphere/nodule, chert, jasper banding, geode type hollow expansion center. The material in the center was over cooked as impact shock waves form a resonate wave effect and cook from the inside out like your microwave oven. The banding is another resonate effect where the minerals attenuate at different frequencies and are separated. It contains specks of iron which is blast fragments from the impacting meteor/bolide. Sept. 30, 2024.

Looking to identify this rock found in Walker County, Ga. I don’t know much about rocks yet but to describe how it looks, it looks like a knot from a tree. And it has bands that make me think of agate, red/orange part is translucent. When I washed it off, the center crumbled out and is now hollow.

Impact disk variant. It may contain iron and impact ash/slate/shale. Magnified you can see the common particle structure. The common particle structure is impact pulverized material sorted by distance or from a uniform impact storm. You can see the crater in the lower left of this USGS magnetic anomaly map (circled). So why a geometric shape? Type 1 impact bricking crossing grid harmonic. Jan. 28, 2025.

I'm posting in both the GA and NC/SC groups, since it was found near the state line...
This one has me stumped... Found yesterday at Lake Chatuge near one of the locations where corundum has been hunted to death for a hundred years.
Weathered, with remains of a steel-gray surface color. A slightly tapering hexagonal crystal form; opaque; SG = 2.8; hardness varies depending where scratched but consistently < 3; brown streak. These physical properties don't match any mineral that I know of.
I'm thinking that this is a type of pseudomorph, where the original crystal forming material (possibly corundum) has been altered into whatever this is now, while retaining the original crystal shape.
<<< Warms Springs, Meriwether County, GA
Is the Roosevelt Impact Crater Complex the biggest Crater in Georgia. No. A very large crater series crosses Georgia, but the biggest internal crater is the coastal craters of Georgia. Now that one is a woomper. Warms springs and F. D. Rosevelt State Park has some small craters hence the warm springs that cracked the crust. Jan. 28, 2025.
But here is the real biz going on at Warm Springs an old punch through type 1 accretion impact. This is a crater complex of many earth impacts. Remember the average US state has around 2,000 based on Mars. Jan. 28, 2025.
Not One Crater >>>>
Craters and rivers. Rivers naturally find their way around a crater. Sometimes they go outside the wall and sometimes hug the inside wall. Feb. 3, 2025.
Impact Sphere, Helena, GA in the above crater zone see below. Notice how closely this resembles the Tektites. If held to a light shining through it may be a tektite. Feb. 3, 2025.
The topo diamond shape crater near Woodbury, GA. Thought to be a tear in the Roosevelt Impact Structure wall but with the average US state having around 2,000 surface impact craters of a mile diameter or greater is more likely to be an impact crater. Feb. 3, 2025.
So is the Roosevelt Impact Structure one or many craters? Many. Here is the Georgia part as shown on the Chegg Products & Services Geology Anomaly Map. These maps are like x-rays and MRI's they show things differently. This big crater would not have a central dome at the Roosevelt Park. The closer tektite maker is shown by arrow also a crater series. Feb. 3, 2025.
Here is another test just like x-rays and MRI's, the Strontium test. Some meteors have it and some don't. You can see the separate circular Strontium crater on the Alabama side i.e. what happened in Georgia stayed in Georgia. Feb. 2, 2025.
Now here is a look at cobalt. There is no unified impact structure crossing over the Georgia to Alabama area from a meteor containing cobalt. No 120 km crater. This is a bunch of craters not a single crater. The Roosevelt Impact Structure is being over hyped. I don't think crater mapping is a skill set for planetary geologist as they are so limited with only two diagnostic tools, shatter cones and Planar Deformation Features (PDF). I found a PDF recently but that does not map a crater. You could have PDF on a side of a crater from 5 to 500 miles diameter. The PDF you find 500 miles away could be from a 5 mile crater there. Shatter cones are not understood by geology in general including planetary science. Striated shatter cones are a low pressure made signature usually found at smaller craters. Feb. 3, 2025.
Liquid not resonate impact sphere. This is the kind of thing you see when you stir color into paint. No, it did not happen over eons of time more like minutes again like paint stirring. Crater shown below. Feb. 3, 2025.

And there is Towns County, GA
And there is the Towns County Crater as shown on the gravity anomaly map. As you can see in the picture above the Towns County Rutile is atypical a shock made variant. These variants are often the result of higher energy and fast formation. Feb. 6, 2025.
Impactite splatterform. Kinetic explosions make explosion strings. Kinetic explosions have great chaos as matter is being ripped apart. Nano iron has been imparted to the specimen as Fe3O4 black and red. If you wet it you will have a "dark matrix" specimen. These type impactites also appear as fossil conglomerate pieces in dark matrix but this is not fossils. The most interesting feature is linear Constellatioining. This can be seen at highest magnification. Linear Constellationing is a type of fiber crystal but encased in the matrix. This is a type 2 impactite containing both surface and impacting bolide material. Feb. 17, 2025.

​Chattooga County in Red Mountain Formation. I was looking for seashell fossils but this seems really unique. Any idea what causes this?
The Floyd/Chattooga County, GA Crater. Angled impact with central uplift a type 3 surface exploding impact a stop and pop. Feb. 17, 2025.

Lee Isham neat is that the black circle? This rock came from one ridge to the west of that circle. Private property
Shale or sandstone? Shale as an impact ash is more likely. Some good fiber crystals on surface. The Red/Black is iron oxide. The black is a charged effect similar to a lightning discharge but makes a deposit. These broken shards show they were once connected and got this surface effect from the shock chaos storm. Feb. 17, 2025.

Chattooga county in Red Mountain geology. Whats going on with the black lines? Is it shale?
Impact mega clast Redtop Mt. State Park Bartow County, GA. This crater is primarily in Cherokee County.
The big 4 radon circles of Georgia. These are the same typology as impact circles with a central uplift and the crater wall push out. March 1, 2025.
Another interesting Georgia Circle as was mentioned above rivers and streams often conform to old craters. Now the new theory is these tektites (Georgiaites) are from the Chesapeake Bay Impact. (March 2. 2025.)
Even if you ignored the statistical weighting of the concentration of the tektites to a couple of counties and extend the counties as a line it does not point to the Chesapeake Bay Impact Crater. Also the impact debris would not extend that far as a concentration. A strewn field would deposit back to the crater of origin. March. 2, 2025.
So, the convoluted theory posits that the tektites landed in the then sea and were washed up by the tidal wave caused by the impact. Wow, how does this stuff get published? A tidal wave would not align with these two locations. As you can see in the above topo map the old shoreline faced the ocean and there is not backstop facing the Chesapeake Bay. And never mind you can see a crater between the rivers encircling it. March 2, 2025.
The average angle of impact is 45 degrees. So, you can see the angle and that makes a back blast. The ejection velocity is roughly twice the impact velocity caused by the explosion compression. March 2, 2025.
Weak but present gravity signature from the tektite maker impact. Why weak? Tektites are impacts into sand and 37 million years ago a sandy sea more likely and impacts generally decrease in size and power over time whic his why the Chicxulub impact is considered an extinction event and the Chesapeake Bay Impact not. March 2, 2025.
So, now let's look at the Georgia Volcano Theory. Shown below is Hawaii. Just look at the difference in intensity. Impact makes a circle of these crest whereas a volcano tends to crest together. March 2, 2025.
Two more topo craters and an oval as identified by the water flow stream structure. March 2, 2025.
Radium Springs, Georgia
The Big and Old Crater.
USGS Uranium Map -
Radium Springs is an unincorporated community located on the southeast outskirts of Albany in Dougherty County, Georgia, United States. It is part of the Albany Metropolitan Statistical Area.
Radium Springs is best known as the location of one of the "Seven Natural Wonders of Georgia": the largest natural spring in the state. The deep blue waters of Radium Springs flow at 70,000 gallons (265,000 liters) per minute and empty into the Flint River.[1] There is also an extensive underwater cavern system.
The water contains trace amounts of radium, and the water temperature is 68 °F (20 °C) year-round.
Prior to the discovery of radium in the water in 1925, the site was known as "Blue Springs".

And there is that big SE USA crater. It appears it was later hit by not radioactive meteor/bolides and broke up the ring however the radiation would still be there, just pushed around, like into the underground aquifer. March 4, 2025.
You can see the later smaller impacts into this large SE crater wall much better with the USGS Thorium map. March 4, 2025.
USGS SE USA Uranium. Now you can see much better the subsequent impact into the SW Georgia area. Including the topo crater remnant wall shown right you can see other traces of impacts into the big SE crater wall. March 4, 2025.
Impactite, chert/shock metamorphic. First let's start with vugs. Not a tectonic process for obvious reasons. Next the iron inclusion which is indicative of some iron inclusion making process (see attached circle 1). And finally, it is a multitude of chevrons mostly pointing in the same direction (see picture circle marked 2). While shatter cones are sign waves the triangle wave is also likely to emanate from an impact disturbance. In the Howell, TN Impact Structure I found cones, sawtooth wave and triangle wave imprinted side by side. How far are you from a crater if you find an impactite? Usually not far or inside the crater.

Could this be a fossil? It was found in a creek in Decatur, DeKalb County, Georgia.
Dekalb County, GA is in a complex of craters. March 6, 2025.
Here is a little better look at this crater complex. Gravity low craters are innies that did not make the surface dense. This could be a low iron meteor/bolide that mostly explodes on the surface and distributes itself. Some go into the earth through the crust. You have to remember that meteorites today can vary in speed from 10 to 28 miles per second. The high-speed impacts are more likely to penetrate the earth's crust as a ballistic impact. March 6, 2025.
Natural shock made citrine with slow cool which allowed it to make crystals. It is rare. The body appears to have been impaled in flight. How can I tell it is an impactite? When magnified you can see the linear flow direction of high velocity flight while in a high heat state certainly higher than 2,000 degrees F which is the limit for volcanic lava. Look closely at attached magnification and you can see the striations. March 6, 2025.

Acanthite presents as dark gray to black crystals with a distinctive metallic shine. These crystals often form elongated prisms or tubes, and sometimes appear in pseudo-cubic shapes.
An interesting feature of acanthite is its ability to change form at different temperatures. Above 173°C, it transforms into a different crystal structure called argentite. This transformation can create unique patterns and shapes in the specimens.
The crystals often group together in complex arrangements, forming branching or tree-like structures. These intricate formations make each specimen unique and visually striking.
Acanthite is considered one of the most important silver ores, second only to argentiferous galena. Its high silver content makes it particularly valuable for collectors and rockhounds.

Here is some interesting detail showing the moving gradient and plasma cavitation in this formation. This is the type of blast crevasse you get when inside a crater. The slope will be more consistent with distance. March 10, 2025.
Coquina, and beach rock theory. It is thought that this is a normal sedimentary rock from currents and waves. It sometimes contains iron and is often high in phosphate. Meteorites often contain iron and can be high in phosphate. Coquina is found in Twiggs and Wilkerson Counties which are not next to the Savannah River which would be the sedimentary theory for the active pressures. The gravity map of Georgia circular features aligns with where Coquina is found. See attached USGS gravity map. March 18, 2025.
