Geology Quiz

There's a geology quiz up at Eunoia.  Identifying rocks from photos is a pain in the arse, but really, who can resist a good challenge?

If you can't, head on over and give it a whirl.

Pretty confident about 1: black shale w/pyrite, and 3,4,5 look like various forms of calcite crystals. Not sure about 2- maybe Cu minerals? or 6- possible limestone or similar.
