Be that as it may, the question was what is the most common form of that mineral, not necessarily that sample. gotta read the fine print :geek:

First off that was written quite long ago, and second, that is halite.
Is the answer to the last question going to be posted soon?

Yeah, that was one of the first questions here. Isn't it used as tablesalt? I've seen it being mentioned in numerous places that an identifying test is to lick it, and it has a salty taste. Of course, I wouldn't lick rocks at competition, but that's just me.

I want to say it's either diorite or gabbro, I'm thinking gabbro since it has a sort of dark color about it. In either case, it would be formed by slow cooling and crystallization of magma deep underground. As opposed to the rapid cooling of rocks like pumice.
p.s. i like your signature, that's a beautiful song
