Genesis of the Huangshaping W-Mo-Cu-Pb-Zn polymetallic deposit in Southeastern Hunan Province, China: Constraints from fluid inclusions, trace elements, and isotopes

摘要

The Huangshaping polymetallic deposit is located in southeastern Hunan Province, China. It is a world-class W-Mo-Pb-Zn-Cu skarn deposit in the Nanling Range Metallogenic Belt, with estimated reserves of 74.31 Mt of W-Mo ore at 0.28% WO3 and 0.07% Mo, 22.43 Mt of Pb-Zn ore at 3.6% Pb and 8.00% Zn, and 20.35 Mt of Cu ore at 1.12% Cu. The ore district is predominantly underlained by carbonate formations of the Lower Carboniferous period, with stocks of quartz porphyry, granite porphyry, and granophyre. Skarns occurred in contact zones between stocks and their carbonate wall rocks, which are spatially associated with the above-mentioned three types of ores (i.e., W-Mo, Pb-Zn, and Cu ores).
