Websupergene 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 … WebOres produce cracks in the surrounding rock that generate inverse gravitational fields. Metal enrichment in subduction zones is a result of: a. Dissolution and precipitation. b. Differential melting and density stratification. c. Magmatic segregation and mantle convection. d. Hydrothermal activity and fluid enrichment of magmas.
