Out in the Black Hills of South Dakota we found an old abandoned mineshaft, possibly a tin, gold, or silver mine. I've never seen something like this but it was super cool.
I did some research on the rocks we saw in there and came to these conclusions:
1) The "coal" we saw is actually probably graphite
2) The greenish crystals we saw is Melanterite or Iron (II) Sulfide, which is a common byproduct of mines. It actually is a little toxic and can gradually turn to sulfur gas over time...
3) The blueish crystals are something along the line of copper sulfide or the like. The copper is likely what gives it the bright blueish-green look.
