That makes sense and it's good to know. I'll have to knowledge up on my rock facts.
Thanks!
i posted a few microscope pictures up top. what i neglected to mention is that the stretched crystals recrystalize, so single crystals won't lock stretched under the microscope. but you can (maybe) see the white crystals, which is quartz, then some brownish stuff, which is either impure quartz or mica crystals, and some black platey stuff, which may be biotite mica
but please: see disclaimer in above post. i could be talking out of my ass
Damn, you brought your A game to this rock community. Those pics are fantastic.
what can i say? i do like rocks. ¯\_(ツ)_/¯
