I thought I'd share this specimen of mine with you folks. I knocked several pieces out of a fracture in granite. This stuff is very rare world wide. A lot of the owyhee mines contained this material, but since it was ore it all went through the mills.(Crushers)I had some better examples, but I gave them to some of my mining buddies up in the Boise basin who had never seen an example of it. Anyway! it's a pseudomorphic mineral where calcite or possibly barite was completely replaced by quartz. The plates are composed of cryptocrystalline quartz grains and some of the plates have microscopic quartz crystals radiating up from their surface. Robert

This is the only picture I could find quick. I find a lot with more of the plates than this one has but this is about as big as I find them. I have not dug there only surface collected. Keith

I have never found any loose Quartz points there, only this type with crystals and small plates covered with crystals

kap! Thanks for posting the pic. I wish I had taken pic's of the pieces I gave away, one was red & white with some yellow, the other was yellow & red, and they both had a lot more of the triangular cells showing. I can get more if I want them, but it requires driving way back in, ( where the hoot owl done the chicken ) then a long hike up a very steep mountain. I can get pieces up to 50 pounds, but with my bad ankle, trying to carry them down that mountain is darn near impossible for me, so I just grab chunks 5 to 6 inches across. That size fits into my ore bags and my back pack real nice and leaves both hands free for catching myself during the occasional stumble during the descent. The big pieces would be destroyed if I tried to roll them down, so I just leave them in place. If you find more pic's post them here. Robert

That is cool!
If you need help packing some out give me a holler, I would be happy to help you pack some larger ones out.

Very interesting. We have found some small pieces like that but didn't know for certain what it was.
