The meteorite impact theory was not based on just a couple of stones, there were hundreds of stones/gemstones that were found to have been altered, modified or morphed. This stone is just one of so many. 41.jpg 42.jpg

These samples do appear to show high-pressure "spallation" shock evidence. Samples from a 1986 impact crater study resemble some of the unique features within your suspected impact rocks. I'll include a couple of reference photos below...and good luck with your future research on the topic.

* I would guess that 99.9% of everyone speculating the origin of this material by sight would classify it as volcanic/obsidian related. And, of course they would be wrong.

Thanks for sharing the images. When I researched this specimen, I could not find anything to compare it to as an impactite. Some of these have turned out to be a real head scratcher.

You make statements like the bolded one, but I am curious, what are your credentials in this field? These rocks and most of the ones posted recently are clearly terrestrial rocks that are not impacted related and even a well-versed layman can determine that. So, I am wondering, if this well-versed layman (me) is wrong, then I want to know how knowledgeable and qualified the opposing opinion is. I freely admit that I have no academic credentials in the planetary sciences, but I have also been an active member of the meteorite scientific community for over a decade. I collect and study impactites, tektites, melts, and other impact-related specimens that I have acquired from respected sources in the field. I have owned and held in my hands every type of impactite known to science, from localities around the world. Nothing in my experience resembles these. So, before this parade of dubious rocks continues unabated, please tell us a bit about your credentials to be making authoritative judgements on specimens in defiance of what several experienced and knowledgeable people are trying to tell you.
