Since I'm currently missing the "world's biggest" Tucson Gem & Mineral Show," I thought it might be fun to start another geology thread.
Golden Barite BaSO4(also spelled Baryte) crystals from the Meikle gold Mine, Elko Co, NV.
Ain't they purty!

A Gud question. I fully expect rocks without pedigrees, cliffs, mountains, music, & whatever might be related in the minds of those attending.

Depending on the answer to that question, this could be OT... But I like it!
Edit, whew, on topic after all :)

Cinnabar, HgS, sometimes used as a red pigment in tattooing. No thanks on that.

Fine rocks all! Thanks for sharing!
T Hocking. I see limestone cliffs & a limestone cave on an island. Otherwise, I'm stumped.

Since I'm currently missing the "world's biggest" Tucson Gem & Mineral Show," I thought it might be fun to start another geology thread.
And since I, too, am not in Tucson where I'd intended to be this week, I think it might be fun to post to your geology thread...
Can anybody give me a clue about what's going on (geologically speaking) here?
And for scale:

Ghost! Thanks for posting. To call the inner chunk of rock "an inclusion" is not enough.
Looks like a chunk of limestone or maybe dolomite, that has survived being surrounded by other sedimentary rocks.

Bronchanite, a copper mineral Cu4(SO4)(OH6), from the Milpillis Mine, Cananea, Sonora,Mexico. Both the bright green crystals & the larger dark crystals are Bronchanite. When I look through the dark crystals in bright light, they are a slightly deeper green.
I do like the color!

Thanks for the cool thread and great crystals!
Tucson was awesome, as usual. Anyone who is into crystals or fossils or rocks in general should plan to go down there sometime for the February show.
