There is so much going on with this large, rich plate of copper minerals that it is hard to describe it correctly. Basically what you have is layers of copper minerals with very similar chemistry layered atop one another. The greatest mass of the plate appears to be chrysocolla. There is a thin layer of cornetite that appears to be topped by micro-botryoidal, lustrous malachite. I believe there is even some heterogenite here. The surface is quite lustrous.
