Texas, USA Craters - Follow the money. In geology you will find a lot of interest in resource finding like minerals, oil, water. That is how they found Chicxulub, looking for oil. Craters can be an oil sink and impact is the source of surface minerals and gem stones. Most of the earth impacts pre date the oil forming period or so they think. The burnable rocks in Middle, TN are carbon impactites from one or more of the many pre high carbon periods.

Derrick Whitehead collected this specimen outside LaGrange. Alien facehugger? High shock, may have been a conglomerate. Besides iron, manganese, and silica it has a beautiful shock particle storm surface. A sequence however small the time during the impact chaos. The surface particle storm "constellationing" is also in a high shock state and has clustered into a "constellationing galaxy."
Specimen above was collected by David Chidgey at Persimmon Gap near Big Bend National Park in SW Texas. It is a high shock impactite. Silica based sand that has multi minerals it received in nano form from the shock impact blast. It also has a "Constellationing" flow surface where the shock particle storm is blasted away from the explosion. While Trinitite from the atomic bomb test is melted to this degree, impact is a kinetic based explosion and melts by shock pressure wave. Atomic weapons are a heat dominate explosion that also produces a pressure wave.
<< Would you look at all those crater wall faults! Was a really big Gulf Impact.
The only thing they got right here is the depth and perhaps the date.
And here you can see the big offshore crater. This is way bigger than Chicxulub. Perhaps 5 times as big or more. Later the Chicxulub Impact modified the east side of the crater.

Katie Cook of Comanche, TX found this tri welded impact spheroid group. This is a phenomena like hail stones but caused by the explosion melt on impact which is launched outward. In this case the spheres did not get a chance to form independently.

OBITUARY OF MICHAEL STUART STANTON
October 1, 1917 – June 23, 2014 With loving memory and great sadness, our family announces the passing of our dear Michael at the age of 96 years on Monday, June 23, 2014 at the Foothills Medical Centre, Calgary. Michael passed away peacefully with his family at his side. Michael Stuart Stanton was born in Leamington, Warwickshire, England on October 1, 1917, and immigrated to Canada in 1919 with his parents. He attended the University of Manitoba receiving a Bachelor of Science degree (Honours) in Geology in 1939 and Queens University, Kingston, Ontario, receiving a Master’s degree in Geological Engineering in 1941. He served as a navigator with the RCAF during the Second World War from 1943 to 1945, and married his life-long companion, and best friend, Ellie, in 1945. Mike and Ellie were married for over 62 years until Ellie passed away in 2007. Mike has been greeted by his dear Ellie and his loving parents Elizabeth and Peter. In his early career, Mike worked as a geologist, pioneering field work, mapping and mining geology in Manitoba, the Northwest Territories, the Yukon and the Arctic. During these years Mike worked with the Geological Survey of Canada, the Manitoba Mine’s Branch and the Hudson’s Bay Mining and Smelting Company (Flin Flon, Manitoba). Mike continued his career as a petroleum geologist with Chevron Standard (California Standard) in Calgary for over 33 years, from 1949 until he retired in 1982 at the age of 65 years. Mike was an accomplished and respected Geologist. He is credited with many professional papers, scientific articles, reports, publications and discoveries. His very active and inquiring mind did not dim with age. He was writing scientific articles well into his mid 80’s, several of which were picked up for publication in both Canada and the United States. Mike was a proud and lifetime member of APEGA, the CSPG and the AAPG.

How large a body would it take to make a crater as wide as the Gulf of Mexico?
JIM BOWERS, NEWTOWN SQUARE, PENNSYLVANIA
Published: Sunday, May 1, 2005 Astronomy Magazine
The Gulf of Mexico is the result of plate tectonics, or "continental drift," in which the plates comprising the Earth's crust change position over time. The Gulf did not even exist in the distant past, and its size and shape will slowly change as time progresses and tectonic plates move.
To simplify matters, let's replace the Gulf with a perfectly circular sea having the same total area. The Gulf has an area of about 600,000 square miles (1,554,000 square kilometers), which means we can replace it with a circular sea 875 miles (1,410 km) across. Now, there are two ways to estimate the size of an impacting object from the size of the resulting crater. The first is an old rule of thumb: An asteroid or comet will make a crater about 10 times its size, or in this case, 87.5 miles (141 km).
A more rigorous approach is to adopt mathematical relations for crater size developed from nuclear weapons tests. With some assumptions on the ground composition, this will give us the explosive energy needed to make the crater, and we can translate this number into the body's size by assuming an impact speed. To form a Gulf-size crater in rocky soil, the energy required is 14 trillion megatons. If we assume an impact speed of 45,000 mph (72,000 km/h), the culprit body must be about 51 miles (82 km) across.
Both numbers are estimates. The rule-of-thumb approach ignores the body's impact speed, the composition of the ground at the place of impact, and the composition of the comet or asteroid, among other things.
The second method is designed to account for some of these variables, but it is based on nuclear tests with relatively small explosive yields — at least in comparison to the impact energies we're discussing — and there's no way to validate the results at such energies.
However, the fact that the two numbers are in the same ballpark suggests our estimates probably aren't too far off. So it would take a comet or asteroid between 50 and 100 miles (80 to 160 km) across to produce a crater the size of the Gulf of Mexico. — BILL COOKE, MARSHALL SPACE FLIGHT CENTER, HUNTSVILLE,
Now what this model fails to consider is impact absorbing. An object this large does not surface explode which is how the model is based. As you can see from the gravity magnetic anomaly maps the crater contains much of it's original mass as a shock made deposit in the earth's crust. Objects this large can also even penetrate the earth's crust if going fast enough and be absorbed by accretion and inflate the mass and size of the earth.
Jacobs well near Wimberley, TX north of Austin. This is a karst feature common to crater wall rubble areas.
Improved mapping of the Gulf of Mexico shows what the earth really looks like showing cratering without vegetation. Mars has over 600,000 craters of a mile diameter or more and is about half the Earth's size. You are seeing cratering along the slope of the very large crater that made the Gulf as cratering is a progression of large to small over time as the Universe sorts its explosion material.
So lets take a look at this post Gulf of Mexico making crater, a smaller crater. It hit into a salty sea and compressed the organic material into oil. It was a direct compression hitting almost straight down but not a sphere as you can see the crater shows the mass arrangement of the impacting bolide. Jan. 19, 2023

Found this on a property we purchased in Athens Tx. I’m loving the deep red and black. Any idea what it may be? I don’t usually see these deep colors in northeast Texas unless it’s iron but this feels a bit waxy/smooth- not rough like iron. Of course it could have come from a different location….

Found at Wright Patman Lake in East Texas. There is iron ore all over this beach. I found this strange little guy and I’m just trying to figure out more about it. It looks like it was molten iron that got flash frozen. I don’t know enough to guess. That’s why I’m here.

Has anyone ever seen anything like this? Maybe some kind of fossil. Found in West Texas near Andrews.
An impactite with plasma hole burns. Impact releases trillions of mega tons of explosion energy. While a bomb wants to make a single source explosion the impacting bolide is not uniform and it is a multi source explosion with "local effects." While the tunnels in your specimen are what you notice most the holes are indicative of plasma burns. The tunnels are just moving bubbles. Attached is a lab experiment of high energy plasma discharge. So why not worm tunnels? To petrify this effect you would need an instant method to turn moist dirt into rock. So now you have two events required. The ceramic process would be 2,000 plus degrees. Requires a catastrophic event. Also you need to produce a nodule not a strata. A piece of unfired greenware like a nodule is fragile and will dry out and crumble. Impact plasma burn holes satisfies the physics required with one event. Feb. 21, 2024.

Most impacts that make a crater make a round crater. This is because explosions expand in all directions equally. But when an incoming meteorite strikes the ground at a shallow angle — less than 15° above the local horizon — the resulting crater is no longer circular. Low-angle impacts produce craters with an oval outline. Here you can also see it came in from the west. June 19, 2024.
Big crater with crossing fault pattern in OK. The crossing pattern of faults is what you can see in smaller crater that are not buried. It is what you see when a bullet hits glass, radial and vertical cracks. See picture below. July 6, 2024.
Impact sphere cluster which would make it botryoidal. Type 2 impactite. A type 2 impactite is one that has both the impacted surface and meteor/bolide composition. A close look shows bits of iron and cobalt from the meteor/bolide. It is mostly the impacted limestone which it turned to liquid and expelled as round drops. Why a cluster? The closer to the impact the more crowded the impact drops. Are clustered impact spheres common? Not really although I have many on my encyclopedia of this phenomenon, but I collect variants for the public benefit. So where is the crater? You can see the crater on geology maps and topo maps. It is a relatively large crater and came in from the west which is a type 2 subduction type crater or what is called a crater complex. Is your rock valuable? Yes, people are fascinated by impact spheres, and it is my most popular chapter. July 17, 2024.

I was wondering if this is coprolite. I hope it is because I tell everyone its dinosaur poop lol. Found in Seguin Tx . Reminds me of what fossilized horse poop would look like. I've had to move a few times and unfortunately it's started crumbling in a few areas.
Impact Sphere/Nodules. Notice how they vary. This is related to the amount of melt when formed. Kinetic explosions are not uniform. They are multiform explosions. The iron came from the impacting bolide. Concretion theory: The idea that iron precipitates from a toxic sea is not credible. Chemically salts precipitate. Is iron oxide a salt? Not a salt
Iron oxide is not a salt1. Iron (II) oxide adopts the cubic, rock salt structure, where iron atoms are octahedrally coordinated by oxygen atoms and the oxygen atoms octahedrally coordinated by iron atoms. Next we have the Mississippi Valley Type Theory, formally known as Spring Release 19th century. It conjectures that a crack in the earth's crust released iron. In the century plus life of this theory no such crack has ever been found in association with the specimens. Impact theory: Impact explains the iron and the forms associated with the iron. Unlike Spring Release/MVT you can find a crater associated with specimens found. Take a look at the gravity map of TX. It clearly shows the associated crater. Sept. 7, 2024.

Fairy stone variant, impactite. These high shock melt formerly bedrock specimens are associated with large earth impacts. The tubular point version is aerodynamically made by the high velocity of the ejected melt drop. So, what does the crater look like? Big, see attached gravity map. Crater name, Big Texas is distorted by the later impacts as the sorting nature of impacts goes from big to small over time.
Fairy stone variants, impactites from big earth impact. The teardrop shape is a result of it being liquid when ejected from crater. The false strata striation is from the imprinting shock waves.

I don’t know much about geology and fossils. Found these building a fence in central Texas. Very odd looking for rocks. Are these some sort of fossil? Thank you!
What is interesting about these impact spheres is they are small, indicating a smaller crater. Sept. 7, 2024.
I would love some insight into what they articles might be - located in South Texas - Sonoran desert area. These are beautiful spheres - several are darn near perfect. Also, they do show a weak magnetism. My geology background isn’t too extensive (maybe 18 or so college hours) and my son, 8, is an avid collector of all things mineral, rock, fossil related.
Impact nodules, the iron is from the impacting meteor/bolide which forms melt blobs in the impact explosion. Note, these are also found at the Barringer/Meteor Crater, AZ. Some are cojoined as these spheres get too close and merge. Some have mosaic cracks as they cooled too fast. Cooling too fast can cause them to crack apart. Cooling slow allows for the formation of crystals which your 7 o clock specimen is doing. Impactites can be found in a blast spray like your yard. The crater that made these is a large Type 2 subduction impact. It came in from the west exploding and burying into the earth's crust. Nov. 9, 2024.

Needle Peak, TX Impact Crater. It contains shock agates. It also has impact basalt as found at the Wetumpka, AL Impact Crater. Nov. 9, 2024.
Conglomerate/breccia impact sphere from east side of Needle Peak. Nov. 9, 2024.
Impact craters above the relative lower topography. There are two ways this can happen. The first is the impacting meteor/bolide hit into a higher area in this case the Bandera Mesa which just modifies it with an impact crater. This would include the intermountain cratering. The second is a delayed explosion uplift called a crater retark. Nov. 9, 2024.
This is actually one of the best classic craters in the United States. The reason being the angle of impact. Most impacts are at 45 degrees on average this one was more straight up. The Needle Peak feature is an up-splash phenomena. Consider the attached picture by Robert A. Jones it shows plasma cavitation holes in the midground boulders. This feature is also found in Trinitite from the first atomic bomb crater only small in proportion to the explosion this explosion being thousands of times greater. Nov. 9, 2024.
Impact nodules. The boxwork type patterns are an energized pattern i.e. fractals like lightning. It was so hot you also have high heat mosaic voids. They are dense because shock has compressed them. So, let's discuss a little physics. Sedimentary theory would have you believe that the veins were once cracks and filled under pressure and the surface has eroded away to cause the voids. So, why is it on the earth's surface? Why would the crack filling mineral be identical? Mud crack impression theory would say the ridges are just fill impression of mud cracks. Not possible to fill that way as a circular process with wrap around ridges. Jan. 25, 2025.

Dug these up today while hunting for fossils in north Texas, for reference they were both about 10-15lbs and I wear a size 11 boot. Does anybody have any idea what these could be?
Impact nodule, fluidized flow around inclusion. So why not fossilized wood? Is no grain continuation it exists as a free form. How about a slow formed sedimentary concretion? So, what did it concrete from, the rock is homogeneous? It looks like sandstone which is totally inert and does not precipitate. Jan. 26, 2024.

First let me say although the slow concretion theory is popular it is an impossible physical chemistry. While you can get rust deposits on your tubs, sinks and commodes, if you see something like this, panic. This is a fast formed impact made concretion/drop. As an impactite its crystal structure will be as random as the explosion chaos that made it. Most iron impactites are not magnetic, but more will be magnetic than will be radioactive statistically. Back in the 1960's NASA proved you can make iron magnetic with shock and vice versa. The USGS does fly over magnetic charts which I often consult when looking for impact craters. Brown County being in the center of the state is part of a large magnetic disturbance. Like impactites magnetism is helpful but requires a gravity map and topo map to sort out the multiple craters. March 7, 2025.

Not sure what this could be, it is very heavy. Not magnetic. Found in Brown County Texas.

That is an impactite, a rock made in an earth impact. The holes are plasma bubble burns. It is however a rare example. Most impactites of this nature have red iron oxide colored holes. You have black iron oxide and no iron oxide trace holes. The little black specks are from the meteor material. It was formed in a hotter environment than most. Excellent specimen. March 11, 2025.

A strong earthquake in Texas. 46th this month.© us geological survey
On Saturday night, an earthquake with a magnitude of 5.3 occurred in the Texas and New Mexico area. Fortunately, this region is sparsely populated, so no major damages were reported.
While pumping all that oil out has made the earth crust unstable it was always unstable and the voids impact makes store oil. The earthquakes are just the crust resolving stress in and around impact made rubble which is not compressed well. May 4, 2025.
Impactite called a shock floor. Is from the "up splash" portion of the impact as the coning is usually pointed up. You will notice the small dots in the specimen these are tiny micro sphere bits which are pulverized and fly out from the impact. The Neapolitan banding is called filtering through rock. Basically the minerals get filtered the red iron oxide being from the impacting meteor/bolide. The clouds are a phenomena you also see with shock dolomite a type of fast formed crystal. Specimens like this are somewhat rare. So let me show you the crater. On the attached map you can the big 1,2,3 of Central TX. They are in order from top to bottom. Your crater hit from the NW and is called a type 2 subduction crater which pushes up a side higher because of its low angle impact. Why is this not raft/plate tectonics? Circular forms require a circular cause as simply smashing things together will just make crinkles. May 10, 2025.

The Lamesa Crater. Craters are named for their central town/city or some easy to identify location in or near the crater. This old crater is the source of the oil and gas as it hit and cooked the organics into oil and gas. Illustration is from Stan McDaniel article. The seeping in theory would not make a ring more like a pool. Figure 2 is the subsequent craters which further refine the organics. Now it is a crater complex with more unknown to most people towns as centers. Shale is impact ash as pressure compressed. Depending on how much it is cooked is how much organics remain in it. As a guideline the center crater would not have any organics left but I have found oil shale in the center of the Howell, TN Impact Structure just not much of it. June 17, 2025.
Figure 2
Angle of impact on average is 45 degrees. As you can see the pressure from this impact was toward the SW. June 17, 2025.
And here is that big pile up as shown on the gravity map. As meteor/bolides explode the center is a gravity void. The oil and gas would make a simi parabola on the SW with the deeper plays going towards the center. That assumes a perfect crater which this is not. The incoming bolide was not uniform, and this is not physics class so do not assume a sphere. June 17, 2025.
The Solitario (El Solitario) is a large geologic formation in Big Bend Ranch State Park in West Texas.

Magnification. 1. Circles and lines, this is a Shock Constellationing effect. The linear alignment develops into fiber crystals. The circles are proto shock circles. 2. What is likely fiber crystals. Fiber crystals similar to the metal whisker effect are found in impactites and also some volcanoes known as Pele Hair. 3. Black Iron Oxide or Manganese imparted as a fluid which has filled the crevasses conformally.
So, lets discuss a little about concretion theory. In chemistry, precipitation refers to the formation of an insoluble solid. It can occur by:
-
Reacting two salts.
-
Changing the temperature to affect solubility.
-
A precipitation reaction between two dissolved substances.
-
Emergence of an insoluble solid from solution. As you can see sandstone over sandstone precipitation is an impossible physics. Impact however has no problem melting impact solids into sphere melt drops and blasting them into the debris field.

Proto boxwork with conformal developing inner circle. While the crossing pattern brickwork is not well established as a crossing grid effect (type 1 impact bricking), the developing internal circle is a resonate shock effect much like your microwave oven cooks from the inside out.

The SW Texas Cerium Impactor. 2 July 2025.
Impactite, chert with iron veins, also has a crinoid fossil. The matrix is composed of the common particle which is configured in a shock particle crystallization habit called Constellationing. The iron fractals are grounding as a energy dissipation of high charge. The charge comes from the particle friction in the shock chaos storm and the ionization caused by the extreme temperatures and pressures of an impact event. You of course can recognize the lightning tree fractal structure of the iron veins. What is interesting about your specimen is the secondary calcium vein, Calcium conducts electricity well. Its electrical conductivity is 2.9×107 S/m. It is worse than copper and aluminum by volume but better by mass. It is also a better conductor than potassium and other transition metals generally. However, calcium is unsuitable for electronic circuitry and wiring use because it is highly reactive. 7 July 2025.

Trying to help a friend out near Juno, Tx, anyone have any ideas on this rock?
My first thought was granite/sandstone woth prehistoric root system thats been stained red from iron and oxidation.
The replacement vein root theory. That would presume cracks and void created by the root system however the crinoid fossil is intact and not a void. Nor is the crinoid replaced by iron. Where did the iron come from? Why is the iron being substituted by a secondary calcium vein. What made the hole in the bottom? Attached is the Juno Impact Crater as shown on the topo relief map.

The Val Verde County Crater. Val Verde County is part of a large crater evident by the blast excavation circle in the strata. 7 July 2025.
The Llano Uplift is a geologically ancient, low geologic dome located in central Texas, oil negative crater - An oil negative crater would be assumed to be a non-permeable structure or post carboniferous. Given the size of this crater the former is more likely as impact size decreases over time. All impacts are unique, and the Texas oil negative crater is a deep excavator burrowing all the way into the Cambrian. Non permeable structures resist seepage and therefore increase oil field pressures. 9 July 2025.
The Llano Uplift is a Retarc, a deeper impact explosion. 11 July 2025.
Can you have a triangular impact crater? Yes, it is a fan type which is a variant of the oval type. It is caused by low angle impacts as is the oval. The average impact angle is 45 degrees, but low angle impacts are very oblique. They may or may not be type 2 subduction craters depending on the explosion typology. The Howell, TN Impact Structure is a fan shaped crater. This map:
The Bouguer (pronounced Boo-gay’) gravity anomaly map is a map of the Earth’s gravity but corrected for the height at which it is measured and the attraction of the terrain (free-air, terrain, and geoid corrections). This can be broadly interpreted to indicate changes in the Earth’s crust (low-density felsic crust versus high-density mafic crust). The Precambrian Midcontinet Rift (https://eos.org/features/new-insights-into-north-americas-midcontinent-rift) is seen in pink in Minnesota and Iowa. The Cambrian Southern Oklahoma Aulacogen is seen in pink along the Red River. Both ancient rift systems have been filled with dense mafic rocks. While the Rocky Mountains are a thick accumulation of low-density felsic rocks, resulting in the blue colors. 21 July 2025.

Not sure what I found. Picked it up in the desert of west Texas.
Mark Kohnitz I found this rock in central Texas near San Antonio. In the hills. Middle of nowhere. No houses, railroads, industries, rivers, or paved roads within miles. Very heavy, around 5 to 7 pounds. Faintly magnetic. Not a natural stone to this region which is limestone). It lay on top of the grass. It had only been there for a short time, as the grass was yellow under it.
Appears to have been subjected to high heat. Probably some kind of slag, but no industry here to have produced it.
I cannot imagine how it got there as the area is remote and untrafficked. Someone would have had to carry it for miles before randomly discarding it within a few days of me running across it.
So everybody assumes this is slag even though there is no provenance to prove how it would have gotten there. 15 August 2025.
Looks like slag also but it is not. 15 August 2025.

Zhamanshin Impactite glass foam!
By Norm Lehrman / July 1, 2017
Figure 2: Zhamanshin glass impact bomb fragment. Laminations within the glass conform to both the form of the foam core and the external morphology of the overall stone.
The piece is a little larger than an open hand and consists mostly of a fragile, coarsely vesiculated glass foam (some reports say similar materials have been shown to be pure lechatelierite indicating temperatures of formation over 1700 degrees C).
