Not a carbonates guy, but suspect this is “black marble”…which could be marketed as just about anything…but likely “Black Granite”!

HenningAnd it's probably larvikite?!
1 7AnthropoceneMan 🦋 ✅I was going to say feldspar…but there was just too much of it.
We don’t get these rocks anything close to this!
Time for the HCL!

Gabriel S. JacobsLook at that variation in grain size! Would this qualify as a porphyry?
1 4AnthropoceneMan 🦋 ✅Man, we have pyroxenites, even amphibolites…but no feldsparites!
I’m think Henning pegged it with the Larvikite. Marketed as “Blue Pearl Granite” because, you know, it’s not a granite at all!

Howard LeeLooks like "Blue Pearl" (sometimes with "extra" &/or "GT") countertop ie an igneous rock comprising Labradorite

Mae SaslawI am a carbonates guy *bangs gavel* I don't think that's carbonate
1 7AnthropoceneMan 🦋 ✅Never more happy to be wrong…and thanks for bringing that expertise I will never get on the upper left coast.

Lockwood DeWittThere *is* marble in Oregon, but it's very restricted. Oregon Caves and up high in the Wallowas are two sites that come to mind.
1 4AnthropoceneMan 🦋 ✅True that…no massive marine deposits.
1Mae SaslawI think you're correct that's it's a granite!
1 2AnthropoceneMan 🦋 ✅I am sure it (and many other non-granites) will be marketed that way.
Mine was a failure of imagination…so much glorious feldspar. What a stunning slab.
I think we have “salt and pepper granite” aka diorite.
The only thing worse than these marketers are the water well driller’s descriptions!
Mike KlingI would guess a Quartzmonzodiorite...
But we need thin sections...
