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 ...
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 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 …
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 …
