Mayum: an orogenic gold deposit in Tibet, China
Ore Geology Reviews, 2009 Abstract Located in western Tibet, China, the Mayum orogenic gold deposit was discovered in 2002 with estimated resources of > 80 tonnes gold. The gold mineralization is hosted by Neoproterozoic–Cambrian schists, and is controlled by nearly parallel E–W trending bedding-concordant fracture zones.
