Genetic implications for the Damajianshan W‐Cu‐As polymetallic deposit in Lvchun, Southwest China: Constraints from H–O, He–Ar, S, and Pb isotopes

Abstract: The Sanjiang Tethyan domain in SE Asia is one of the most important mineral belts in China. The Damajianshan (DMJS) W‐Cu‐As polymetallic deposit is located in the southern part of Sanjiang Tethyan domain, related to Triassic quartz porphyry. Detailed exploration thereafter shows that the reserves of W, Cu, and As are 0.09, 0.42, and 0.12 Mt, respectively. The W is a typical oxyphile element and always coexisted with Sn–Li–Be–Nb–Ta. The Cu–As are typical sulphophile elements and always coexisted with Au–Ag–Pb–Z… Show more

“…The results show that rapid spaceborne reconnaissance of alteration minerals at 20 m resolution can help geological surveys over large areas. In the paper by Zhang et al ( ) , a model is presented for the formation of the Damajianshan W–Cu–As deposit in Lvchun, Yunnan Province, SW China, that developed above a Triassic quartz porphyry intrusion. Pb isotopes and H–O, He–Ar, S isotopes were used to determine that multiple sources of the ore‐forming fluids were derived mainly from the upper crust, mixed with a little mantle component.…”
