Controls on the Distribution of Invisible and Visible Gold in the Orogenic Gold Deposits of the Yangshan Gold Belt, West Qinling Orogen, China [PDF]
Minerals, 2019 Six orogenic gold deposits constitute the Yangshan gold belt in the West Qinling Orogen. Gold is mostly invisible in solid solution or in the sulfide lattice, with minor visible gold associated with stibnite and in quartz-calcite veins. Detailed textural and trace-element analysis of sulfides in terms of a newly-erected paragenetic sequence for these ...

Discriminating fluid source regions in orogenic gold deposits using B-isotopes [PDF]
, 2016 The genesis of orogenic gold deposits is commonly linked to hydrothermal ore fluids derived from metamorphic devolatilization reactions. However, there is considerable debate as to the ultimate source of these fluids and the metals they transport ...

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.
