I'll try to post some more throughout the day. We have a friend that works at Brushy Creek Mine and he brings us a lot of stuff. Eventually I'll get pictures of my personal collection, but here's a few neat ones. Calcite Crystals on dolomite, pyrite and galena matrix. I think this is marcasite on dolomite. Some of have told me pyrite, some have said marcasite, either one is common with Brushy Creek materials. Hope you enjoy and if I start posting too many pictures, just yell at me!

Look at the crystals with a magnifier. If they are cubical, it's pyrite. If they have a kind of rectangular shape, they are marcasite.
