Supergene sulfide enrichmentgeologyBritannica

Supergene sulfide enrichment, also called Secondary Enrichment, in geology, natural upgrading of buried sulfide deposits by the secondary or subsequent deposition of metals that are dissolved as sulfates in waters percolating through the oxidized mineral zone near the surface. The ore thus enriched forms the secondary, or supergene sulfide, zone and overlies the primary, or hypogene, zone.

Gossan or the iron cap supergene sulphide ore enrichment

Gossan is a term from mineral economics. The gossan may also be called iron cap. This is so because it denotes a concretion of iron hydroxides that has formed on top of sulphide mineral vein, where it reaches the surface. It forms during the supergene sulphide ore enrichment, when weakly acid surface water perloctaes through the mineral deposit.
