Bedrock Bob 3,996 Posted October 20, 2020 Share Posted October 20, 2020 It is difficult to tell with no other info than a picture. Is it heavy, light or just about right for the size? Does it scratch glass? Will a hard copper wire scratch it? We're there mines in the area? It looks like it could be sphalerite (zinc) crystals. But it could be a lot of other things too. Specific gravity, streak and hardness would help to identify. The trouble is your rock is a couple minerals (at least) and identification is going to be tough. Quote Link to post Share on other sites

Bedrock Bob 3,996 Posted October 20, 2020 Share Posted October 20, 2020 I have no idea. If it streaked blue green it is indicative of a copper mineral. So I am going to say it is a copper sulfide mineral with some quartz and some hematite in there in places. Not meteoritic in my opinion. Definitely an terrestrial rock.
