I'm not in the least bit offended! I can see how I might have sounded that way - no I'm serious, without actually holding the thing in my hand, sniffing it, cracking it open and licking it, it could well be just about anything at all! The HCL test does tell me it aint carbonate (limestone), though.
Although my wife (geology PHD, I'm actually a geophysicist with an extra undergrad degree in geology) thinks I'm right too. This is very unusual... normally when you show two geologists the same rock you will get three opinions. It's taken me 20 years to learn that you can be wrong about stuff and that it's not necessarily a bad thing.
And as I'm fond of shouting at my peers, and to quote the great Sheldon Cooper - 'geology isn't real science'
cheers,
Andrew.

I respect your opinion, you have 20+ years experience as a geoscientist, I flunked out in first year geology at Uni. (A reflection on my bad attitude at the time when I had a personal war with the entire geology department.)
