In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.
