Anthology I --finally finished!

I still need to clean it up a bit-then it is on to the other 2 matching pieces that will make it a triptych. I really like this piece-- the materials are so wonderful. There area couple of things that I might have done differently (like the white marble) but not much.

This piece has so many different types of minerals in it- I'm not sure what they all are! I do know marble, iron ore, pyrite, chrysocolla, malicate. I don't know what the green colored stone is- or the black with crystals running through it. Any ideas? Anyone?

Below is a close up-- i love the areas with the mineral "dust".
