Orogenic gold deposits of all ages, from Paleoarchean to Tertiary, show consistency in
chemical composition. They are the products of aqueous-carbonic fluids, with typically 5–20 …

Formation of hydrothermal ore deposits requires a fluid with the capability to transport and
deposit metals, and the sources and physical and chemical characteristics of these …

China produces about 450 t Au per year and has government stated in-ground reserves of
approximately 12,000 t Au. Orogenic gold, or gold deposits in metamorphic rocks, and …

Raman spectroscopic and petrographic analyses were performed on samples collected from
zones distal and proximal to the Macraes gold deposit in the Otago Schist of New Zealand to …

The Daqiao gold deposit is hosted in organic-rich Triassic pumpellyite-actinolite facies
metamorphosed turbidites in the West Qinling orogen, central China. Gold mineralization is …

Many ore deposits are hosted by metamorphic rocks, and metamorphic fluids have been
invoked as a source for various deposits, especially gold deposits. Metamorphic fluid …

The temporal-spatial distribution of metallic ore deposits in China, including magmatic Ni-
Cu±platinum group elements (PGE), porphyry, skarn, volcanogenic massive sulfide (VMS) …

Metamorphic devolatilization is thought to be the critical process that can liberate gold from
amphibolite facies source rocks to form orogenic gold deposits. However, a growing number …

The large intrusion–related Qukulekedong Au–Sb deposit was recently discovered in the
East Kunlun Orogenic Belt (EKOB). Mineralization occurs in the Late Triassic granitoid …

Orogenic disseminated and Carlin gold deposits share much similarity in alteration and
mineralization. The disseminated orogenic Zhenyuan Au deposit along the Ailaoshan shear …
