Geological Characteristics and Ore‐controlling Factors of the Beiya …
Based on comprehensive petrological, geochronological, and geochemical studies, this study analyzed the relationships between the Beiya gold‐polymetallic skarn deposit and quartz syenite porphyries, and discussed the source(s) and evolution of magmas. Our results suggest that syenite porphyries (i.e. the Wandongshan, the Dashadi, and the …
Iron isotope constraints on the genesis of giant Beiya Au-base …
(c) Simplified geological map of the Beiya Au-base metal deposit. Modified after He et al. (2015). Considering that Fe minerals are in close association with Au in the Beiya deposit, Fe isotopes provide a good opportunity to unravel the formation processes of Au-bearing iron minerals, such as magnetite and iron sulphides.
Formation of Au-polymetallic ore deposits in alkaline porphyries at Beiya, Yunnan, Southwest …
The Beiya gold deposit is located in the central part of the Jinshajiang–Honghe strike–slip belt, at the junction zone of the Tethys-Himalaya orogenic belt and the Yangtze plate in SW China. This large-scale (125.6 million metric tonnes with a mean grade of 2.42 g/t) Au-rich polymetallic deposit is related to alkaline porphyry …
Mineralogy and mineral chemistry of Bi-minerals: Constraints on ore genesis of the Beiya …
Beiya is the largest gold deposits in the "Sanjiang" Tethys–Himalaya orogenic belt. • Bismuth minerals were recognized from both the skarn and porphyry mineralization at Beiya. • Bismuth assemblages indicate prevailing temperatures exceeding 271 C and fluctuant fS 2 –fTe 2. ...
