Sulfide Minerals (and Sulfates)

The sulfide minerals are repackaged and expanded in this new gallery. They include some striking metallic minerals and major metal ores, like chalcopyrite, shown here.

Today I'm working on the oxide minerals, then after that come the silicates, a challenge to present. Once they're done I'll open all of the new galleries for your contributions.

Update: I see that I haven't mentioned the sulfates, which I did last week. Check 'em out.
