Mineralogy and Mode of Occurrence of Gold, Silver and Bismuth of the Caijiaying Lead‐Zine‐Silver Deposit, Hebei Province

Mineralogy and Mode of Occurrence of Gold, Silver and Bismuth of the Caijiaying Lead‐Zine‐Silver... Abstract The deposit under study is a hydrothermal filling‐metasomatic vein type lead‐zinc‐silver deposit, in which gold and silver can be recovered as by‐products. These metals mainly occur as microgranular native gold, electrum, stephanite, acanthite, pyraragyrite, freibergite, and native silver. Gold minerals tend to be associated with galenobismutite, native bismuth and unnamed Bi2Te. They are either enclosed in pyrite, marmatite, iron‐bearing sphalerite and galens or fill the microfissures of these minerals. Silver minerals usually occur in cleavages or fissures of galena, marmatite and pyrite, but are not associated with gold and bismuth minerals. Gold and silver mineralizations occurred later than lead and zinc, while the silver mineralization was preceded by that of gold. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Geologica Sinica (English Edition) Wiley
