Can anyone help me identify these rocks I found in a new hampshire mine around 4 years ago? I would like to use them on a bookshelf as bookends and as display pieces, but I need to know if I can tumble them. Thank you!

@rocknoobie,
Tes and the rest will probly ID 'em better than I could but I betcha :

1 (?), 2, 8, 12, 13, 14, 15, 18, 21 be granite (mebbe 25, 26);

5, 9, 22 some sort of volcanic--mebbe basalt-- with sparkly mica inclusion;

7, if shiny, obsidian;

8, 19, 24 quartz; 23 and mebbe 20 (if not calcite, which oft looks a lot like quartz)

10, doubtless mica

If a diluted solution of denatured alky doesn't produce bubbling, then it's probly limestone, calcite. Quartz and similar substances. esp w/silica, and which don't scratch easy, can oft be polished. Doubtless somewhere in there is an example of agate or calcedony (maybe 1) taking nice polish

Thanks Noob for the chance to guess

I take my daughter to Ruggles Mine in Grafton every year. It used to be a mica mine and the place is littered with large chunks of mica even now. We've also found some very nice (but small) Beryl's as well.

@rosborne979,
been there on a damned field trip to uncover the Acadian orogeny "Sutures". Everybody wanted to look around for rock specimens.
Ive got a bluish beryl and some watermelon tourmaline that was supposed to be from Ruggles.

Neat place, reminded me of the "Indiana Jones and the Last Crusade" site (Palmyra).

@farmerman,
NO, thats Petra, in Jordan, not Palmyra.
