Thank you for posting this strata. It could be mined as decorative stone. Let me offer a few ideas based on forensic physics and impact tectonics. Sand pushed around and as sandstone into hills and even mountains needs a mechanism to be a solid and up so high. The slow pressure of sediments does not lend itself well to this terrain difficulty. Well then you have raft/plate tectonics, an interesting shadow theory like Plato's cave. You can easily disprove this theory with sheets of aluminum foil at your kitchen table. Push them together and they crinkle but do not make circles.

Next is the idea that toxic minerals condense out of earth seas. Chemical condensates or precipitates tend to be salts.

Iron oxide is not a salt.

This is contrary to the continuation of fossils found in all of these time periods. It is an old theory dating back to the 1800's originally called "spring release" from some earth crack and later renamed Mississippi Valley Type (MVT). No such crack has ever been found to source this theory after more than a century.

Lateral flow and step cracking or bricking is a phenomenon common to impact. Shock of high magnitude makes matter liquid and presents with wavelength layered step banding cracks which as so powerful the cracks are joined vertically by the excess energy. Iron and cobalt are common to impacts and present as surface ores. They are from the impacting bolide.

The physics of this presentation are easier to explain with impact tectonics than with sedimentary raft theory. This stratum is from a big crater shown on the attached link it is large and takes up the NE state crossing over into South Dakota. May 3, 2024.

Geo-Note! This heavy-mineral sandstone outcrop is exposed near an unnamed tributary of Black Butte Creek in Sweetwater County. "Heavy" minerals like ilmenite and zircon are denser than quartz. Flowing water—in this case waves on a beach—sorted the sand grains by density and deposited the heavy minerals together.
