Could somebody tell me the right chemical formula for the new ima
"Pezzottaite"? And does it belongs to the nesosilicates?
Thank you.

NASA finds a way to get kids to look at rocks.  Looks like a good
opportunity for a little local outreach.  I'm going to contact local
science teachers and offer some assistance.

Does every body have any information (biblio or other) on kaersutite (and
green hornblende) as a product of augite tardi-magmatic transformation in
mafic gabbroic rocks. I can give some other petrographic information if
necessary.
