Paul, thanks, don't knock yourself out, but hope you find the photos you're thinking of.
Arrow, thanks, I think you mean "matrix", not "cortex".
Hoss, thanks, in comparing both under a loupe, the little inclusions you spotted in the bigger piece are whitish, and I think the reason Paul was thinking of a porphyritic felsite. They might be in the same family material wise, not certain, can't ID the material of the smaller one, either. I'll send photos to Moody as well, thanks, hadn't thought of that. Porphyritic felsite seems like a decent candidate, though. I think this one is a porphyry material....
At any rate, it never looked like anything that would lead me to say "can't be RI", and if Paul's right, even less reason to doubt it now. It is nice material too...
