Hydrothermal Environment

Part of Hall of Minerals.


A hot, fluid residue, usually of magmatic origin, that is chiefly water contains a rich supply of metallic elements. It becomes further enriched through chemical reactions with the surrounding crustal rock. As it cools, this solution many form massive concentrations of minerals bearing gold, copper, and zinc and other metallic elements that may have great commercial value. Some of the world’s richest deposits of these metals were formed under such hydrothermal conditions.
