DIGGING IN PEGMATITE

[605dano]

Went out today to an old pegmatite prospect and this what I found. I don't know what it all is, especially the black metallic stuff in the quartz. To bad the garnet isn't whole. Some more nice yard rocks for an hours digging.

For only an hours digging you got some nice material, a good garnet, rose quartz and a grab bag of oddities I'm scratching my head on. The last picture is a pretty cool bit with the flat crystals and I'm not sure if I'd call it a feldspar or something else. Hope some of or pegmatite digging members can chip in

The last picture is actually mica. Was lots of mica there but I liked the diamond shapes. Picture is not the best.

Nice finds! I was going to say Mica on the last one.

An interesting color for mica

awesome. just got done panning some material for gold and some gems. reading this makes me want to go back out and keep on panning.

yeah, them are some fat books of mica that's for sure

The pink stuff is likely rose quartz, some nice looking ones at that - if you have a tumbler or have a friend with one, they would probably tumble up real nice.

That silver coating on the one rock is interesting, anyone have any ideas on that one? If it were schist type rock I would think it would just be a phyllite type sheen, but it could very well be silver. Not a pro when it comes to recognizing silver though so I'd like to see what some of the guys think that mine the stuff regularly

605dano, maybe take a look at this link to see if it fits the bill for the silver stuff

Lithium-bearing mica, lepidolite.

I was looking at the dark black metallic material and noticed some small gold colored crystals. I thought probably pyrite, but the crystal shape was not the cubic crystals I usually think of with pyrite. I took a knife blade and scratched the black tarnished part and it was shiny and gold colored underneath. Very hard, the knife would not scratch it. It is heavy but could not get SG because it is in matrix. A powerful magnet had a very weak response. Also I looked at the shiny part on one of the rocks and it was a green mineral with mica. Some pictures, any ideas?
