Very very impressive. It's amazing how good a "simple" isosurface can look :)
Can you post the source please? I'd love to have a look at the isosurface and
radiosity settings.

Except mineral deposits don't hover in mid-air!

Maybe, but there isn't any water around...
For rocks, it's much too smooth, probably. Will have to work on that...

It's really fairly simple, lighting worked quite well, but the geometry is
far from being realistic.

That's a general problem with isosurfaces, you often can't prevent parts
to separate from the surface.

Thanks, but 52 hours for a simple test scene are really quite a lot IMO.
