Since I'm currently missing the "world's biggest" Tucson Gem & Mineral Show," I thought it might be fun to start another geology thread.

Choss ;)

Is this thread for rocks of any size and type or strictly
minerals and gems?

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

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.

Fritz ,
yer analysis is gud so far.
Heres a hint,

Heinous approach I know. :)

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?

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.
