It's a fossilized coral

I'd stick to the marble deposits, or any other deposits of limestone/salt/gypsum/ ECT. I don't really see any typical formation of solution caves in igneous or metamorphic terrains.

The tumbled rock is probably a granitoid

Turbinosamente posted:It's been a couple of chaotic days but here comes an image dump of some of the unidentified shopping network rocks. I'm starting with the ones that have been bugging me the most for decades at this point. This looks like a quartz cluster. Turbinosamente posted:This one has been pissing me off for years because it has always looked fake to me: as in the green crystal bubbles always looked like an induced chemical reaction instead of something naturally occurring. if it is natural I assume the bubbles are the reason this rock would have been advertised for sale on cable television. In a way you are right about this one, in what that is, is a secondary reaction to the original rock which is that dark possibly basalt stone. There is a clear crack in the rock where this secondary mineral has deposited. It is natural, probably a hydrothermal inclusion, of what would be called a botroyidal mineral, possibly gibbsite? Really hard to tell from the photo for me but maybe you'll get a few more shots at ID on that one. It's a cool rock. Turbinosamente posted:and the last for this round of ID request is this that I don't remember having at all, but is neat. I think this is Fluorite Dr. Fraiser Chain fucked around with this message at 02:42 on Oct 12, 2023 |

You got it. It's probably Biotite
