I'm rolling out the whole enchilada now

[Spacetime]

These pieces are a small fraction of the large box of what I thought was lapidary rocks and here we go again something I bought sometime in the last 10 years and in November of 2016 I just realized I had some impactites and some meteorites about 250 different specimens of crystals ranging from a few centimeters to 10 220 centimeters tall there is either a red rustic color on them with some shiny Red Metallic melts that doesn't come off or the yellow melt that covers the other group after reading the traces of catastrophe. available for free in PDF download from the lunar and planetary Society some of these are so severely shot I'm assuming you would take over 25 gigapascals to produce some of the shocks they are sheared PDF planar deformation and fractures melting complete melting and partial vaporization of the crystal all kinds of massive shocked .is the black and white speckled one on the bottom isn't that a form of Martian meteorite this phone will not spell the meteor words and I suck at spelling more to come anybody knowledgeable of the impact crater formation process please make comments now theas pictures do not do these crystals just. I have looped with a 30x Loop every Nano centimeter of these things and they have classic PDF they have extensive high-level shocked planing fracturing twinning these things are extreme the two that are on the red felt as one rock the one that has partial vaporization jetting on the back side crispy in the middle and then on the other side you can just a millimeter or two Of the clear crystal. Left. that one Is just amazing

I fear most are terrestrial rocks. Quartz is in majority in the pics. Are the blackish ones magnetic? Do a streak test. (google it)

 

[Spacetime]

The quartz crystals of course are terrestrial but I'm talking about the massive shock effects in them

 

[DDancer]

As EU says, some crystalline quartz and chalcedony. Shock effects? Nahh. Those are pretty common fractures and the stones are natural not caused by any impact events... except maybe rolling down a hill. The last stones are not meteoric in origin nor do I see anything to indicate that they are anything but terrestrial stone.

Whats the silver looking one?

 

[Eu_citzen]

Just as DD says, I don't see any shock effects in them either.

 

[Spacetime]

What would you describe as shocked effects then

 

[Eu_citzen]

Whats the silver looking one?

Possibly Diorite or a similar rock. The silvery look, I'd guess, is from reflections.

Spacetime look up "shock metamorphism and meteorites" and do a bunch of reading. You'll quickly find out that shock events are associated with large meteoric falls and that the materials created by shock events are very similar to most metamorphic materials. Its good to see your interested in these materials however I also suggest picking up some field guides on rock and minerals and even find a club as this will help immensely in your search.

I have read all the chapters of traces of catastrophe plus several PDFs from the lunar and planetary Society and the photographs I sent them they said clearly these were impacted from a meteorite with the Earth I've also read" in plain sight" Chesapeake Bay meteor impact site and had correspondence with the author David griscom I find it hard to believe that nobody even recognize the Gold Basin meteorite in that picture
