Mineralogy and mineral chemistry of Bi-minerals: Constraints on ore genesis of the Beiya …
The Beiya deposit is situated to the north of Dali in western Yunnan, China. Geologically, Beiya is located in the southern Sanjiang Tethys tectonic domain and to the east of the Jinshajiang suture (Fig. 1).Sanjiang Tethys is named after the three major rivers (Chi: Jiang) in the region, i.e., Jinshajiang, Lancangjiang, and Nujiang.
The Influence of the Ailaoshan‐Red River Shear Zone on the Mineralization of the Beiya …
The Beiya gold polymetallic ore deposit is one of the largest gold deposit in the world. Previous studies have suggested the formation of the Beiya deposit is closely related to the porphyritic alkaline intrusions. Different tectonic models have been proposed by geologists to explain the alkaline intrusions. However, no consensus has been reached and data for …
Trace element geochemistry of magnetite from the giant Beiya gold-polymetallic deposit in Yunnan Province…
1. Introduction The giant Beiya gold–polymetallic deposit lies in the middle of the Jinshajiang-Ailaoshan alkaline porphyry metallogenic belt and is the largest skarn gold deposit in China with estimated reserves of 130.8 million tonnes (Mt) of Au (average grade: 2.47 g/t), 170 Mt of Fe (average grade: 33.3 wt%), 125 Mt of Cu (average grade: 0.52 …
Metallogenic setting and ore genetic model for the Beiya porphyry-skarn polymetallic Au orefield, western Yunnan…
1. Introduction Recent exploration conducted by Yunnan Gold & Mineral Group Co., Ltd in the Beiya orefield in western Yunnan province, southwest China, indicates that has proven reserves of more than 370 tonnes (t) Au at an average grade of 2.52 g/t Au, approx. 200 million t Fe at an average grade of 33.92% TFe (total iron), 0.8 million t Cu at an average …
Beiya Au-Cu ore field, Heqing County, Dali, Yunnan, China
Beiya Au-Cu ore field, Heqing County, Dali, Yunnan, China : A giant porphyry-skarn deposit. The third largest Au deposit in China with estimated 323 t of Au, by the 2.47 g/t concentration. The gold-copper-polymetallic ore bodies are hosted in Triassic ...
Geochemistry and geochronology of Beiya giant Au polymetallic …
The Beiya Au deposit, covering an area of ∼800 km 2, is the largest in the Jinshajiang-Ailaoshan metallogenic belt and the largest Au-bearing skarn deposit in China (Deng et al., 2014; He et al., 2015, He et al., 2016, Chang et al., 2019, Bao et al., 2022
Origin of biotite-rich xenoliths in the Eocene Beiya porphyry: …
Revealing the mechanism of metal enrichment in upper crust is important for understanding the formation of giant porphyry Cusbnd Au system. Whereas, it remains unclear when and how this enrichment process operated in a collisional setting. In this study, abundant Neoproterozoic biotitite xenoliths, entrained by Eocene monzogranite porphyries, are …
Garnet geochemistry of the giant Beiya gold–polymetallic deposit …
Garnets from the Beiya gold-polymetallic skarn deposit have U-Pb ages of 36.4 ± 1.8, 34.8 ± 0.7 and 33.4 ± 1.0 Ma. • They record the fluid evolution history of the deposit from oxidized and acidic to oxidized and nearly-neutral conditions. • In the proximal skarn, the ...
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 …
