I think it might be petrified wood permalink fedilink source parent hideshow 1 child comment replies: [–] Masterkraft0r@discuss.tchncs.de 1 point 7 months ago* (last edited 7 months ago) I don't know. Petrified wood isn't all that common. Why do you think it's that? To me it looks like a finegrained, silicious, sedimentary rock. Might be slightly hydrothermally altered or metamorphosed, can't really tell from the photos. That's not to take away from the coolness of the rock though. It absolutely is a cool rock. I absolutely adore that quartz vein. permalink fedilink source parent
