Self-ordering and complexity in epizonal mineral deposits

Epizonal base and precious metal deposits makeup a range of familiar deposit styles including porphyry copper-gold, epithermal veins and stockworks, carbonate-replacement deposits, and polymetallic volcanic rock-hosted (VHMS) deposits. They occur along convergent plate margins and are invariably associated directly with active faults and volcanism.

NASA - Prospecting from Orbit

Prospecting from Orbit. Mining for ore isn't what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
