Quartz cataclasite
« on: January 27, 2021, 01:32:05 AM »

Found out what this material is called. It is called a cataclasite. Finally got around to slabbing some up. Much nicer than I was expecting.  Found it in green, purple and a mix of the two. Here is the rough:

And the slabs I cut from one of the purple pieces.

Attractive rocks. Would be interested to know where they're from.

Interesting stuff! Looks like it would have a lot of texture or variation in hardness.

Cool brecciated material.  Is it fairly well cemented together?
