In ore deposit geology ,
hypogene processes occur deep below the earth's surface, and tend to form deposits of primary minerals, as opposed
Kaynak: Hypogene (geology)Metals that have been leached from the oxidized ore are carried downward by percolating groundwater, and react with
hypogene sulfides at
Kaynak: Supergene (geology)This
hypogene process is applicable to the original copper sulfide deposition; however, it is difficult to account for the many features
Kaynak: TurquoiseSarabauite's formation makes it the only
hypogene antimony mineral whose fluid inclusions can be studied in thin section under normal light
Kaynak: Sarabauitethey were of
hypogene origin Other precious metals such as platinum form nuggets in the same way. Composition: Nuggets are usually 20K to 22
Kaynak: Gold nuggetThe operation of mining was divided into mining the
hypogene sulfide mineralization (chalcopyrite ) at depth and the shallow supergene
Kaynak: San Manuel Copper Minedescending surface water in the supergene enrichment zone oxidizes and redeposits covellite on
hypogene sulfides (pyrite and chalcopyrite).
Kaynak: CovelliteThe main sulfides are pyrite and chalcopyrite and all mineralization came from processes occurring deep below the surface (
hypogene).
Kaynak: Kerr Sulphurets MitchellThe deeper sulfide (
hypogene ) ore was much more difficult to work and had to be roasted prior to amalgamation. Milling and concentration
Kaynak: Austin, Nevadasecondary sulfides arise from the leaching of the overlying ore and its re-deposition on and replacement of the deeper primary (
hypogene) sulfides.
