John77 Posted June 23, 2021 Share Posted June 23, 2021 (edited) These are pieces of a large rock I found in Utah by a giant copper mine. I smashed it up with a hammer. I love collecting rocks bit I'm terrible at identification. I have tried for a couple hours to figure out what this chunk of stone is made of but I have no idea and need help. It is a composite, so I want to know what the amber and dark orange glass like rock is, what is the slightly reddish red or green rock, and what is the slightly crystalline gray stone it is all surrounded by. Thank you in advance, I appreciate it greatly! And I'm sorry I'm such a newb to rock identification.These are pieces of a large rock I found in Utah by a giant copper mine.

I got most of them wet so they would be more visible in the photos and not just look dusty. Thank you in advance, I appreciate it greatly! And I'm sorry I'm such a newb to rock identification.

Guest Posted June 23, 2021 Share Posted June 23, 2021 The name of the mine would help grestly. Quote Link to comment Share on other sites More sharing options...
chrisski Posted June 23, 2021 Share Posted June 23, 2021 To me it just looks like mineralized quartz. Some phots show what I think are vugs, which is just a hole in a rock mass where minerals precipitate and form.. The brown staining on the quartz is fairly common in AZ.

Bedrock Bob Posted June 23, 2021 Share Posted June 23, 2021 The colored glassy material is chalcedony. The crystalline mineral is quartz. Quote Link to comment Share on other sites More sharing options...
