Cloveri Posted September 30, 2014 Share Posted September 30, 2014 I found these on my ranch...I have no idea what it is and would appreciate any help Quote Link to comment Share on other sites More sharing options...
AuTSaurus Posted September 30, 2014 Share Posted September 30, 2014 (edited) If you have access to a geiger counter, I'd check the stuff in the first picture. Looks like some small pieces of uranium rock/ore that I have seen, but I am far from being an expert. I wouldn't carry it in my pocket though, until I found out for sure.Little piece(shiny/waxy) in center of last picture resembles jasper.Greg Edited September 30, 2014 by AuTSaurus Quote Link to comment Share on other sites More sharing options...
weaver hillbille Posted September 30, 2014 Share Posted September 30, 2014 The yellow coloration in the first pic reminds me of Orpiment((( Arsenic Sulphide)- but then I've only seen pics of it. Others resemble jasper. Quote Link to comment Share on other sites More sharing options...
El Dorado Posted September 30, 2014 Share Posted September 30, 2014 Maybe some opalite too Quote Link to comment Share on other sites More sharing options...
Haderly Posted September 30, 2014 Share Posted September 30, 2014 The green and brown pieces look like common opal. See if you can scratch them with a knife. The yellowish pieces might also be a low grade common opal but it is hard to tell from the pictures. Quote Link to comment Share on other sites More sharing options...
d_day Posted September 30, 2014 Share Posted September 30, 2014 (edited) Hard to tell from the pictures. First picture looks like rhyolite to me, though some parts look more like jasper. Could be it's jasper and it only looks like rhyolite because of the surface weathering. The rest of the pictures look like jasper to me. some of them may be common opal, or opalite as suggested. If you do the knife test Haderly suggested and it leaves a scratch, then you've most likely got common opal.
