Coaldale Crater Gemstones, Meteorite Impact Produces Rare Specimens Options

[ASTROBLEME]

Members and Guests of Colorado Prospector,

Many years ago I discovered a highly eroded, geologically complex and very ancient impact crater centered 3 ¼ miles northwest of Coaldale, Colorado (USA). I am announcing this discovery as a long-time contributor to this forum in an effort to assure that the public has access to this information. Dan (the owner and operator of Colorado Prospector) is preparing some of my "Coaldale Crater" specimens for jewelry settings. He has graciously agreed to document his work progress so that others can gain a better understanding of the effort it takes to transform these raw materials into valuable gemstones. Please take time to follow this project along the way. I hope you find the subject interesting.

I'll be sharing the science behind this amazing discovery as our work progresses. This research builds upon my work at Gunnison Crater, Westcliffe Crater, Silver Cliff Crater and Hillside Crater that proved an extension to the 38th Parallel Crater Chain dating to the Late Devonian Period. Although the Coaldale Crater is also along the 38th Parallel, it is not part of the well documented crater chain system. My efforts in the Coaldale Colorado region included collecting field survey data, acquiring and analyzing numerous geologic specimens followed by an extensive review of the relevant scientific literature. The results support an impact event that occurred during the Oligocene Epoch.

For now, I'm providing the attached map depicting the present peak ring exposure. It is fascinating that this impact crater has survived the deep erosion and strong fault deformation that Mother Nature has provided continually over the past 27+ million years.

Sincerely,

ASTROBLEME

Slickensides:

Earlier this year (without revealing the specific crater location at that time) I posted information about slickenside features that I had observed at what is now named Coaldale Crater. There was some interest expressed in slickenside development in impact craters earlier in this thread, so I'm posting the link for those that want further info.

World Record Specimen?

Now I'm wondering if valuable gemstones can be crafted from some of these "world record slickenside" specimens. There must be a way to reveal a hidden beauty that far surpasses the natural stone. If so, perhaps they could be marketed in order to fund further research ....
