Origin of the Wangpingxigou Pb-Zn deposit in East Qinling orogenic belt, China: Distal response to the giant Donggou porphyry Mo system?

摘要

The southern margin of the North China Craton (NCC) hosts many world-class porphyry Mo and vein-type Pb-Zn +/- Ag deposits, forming an important polymetallic metallogenic belt in China, even over the world. Although the Mo and Pb-Zn +/- Ag mineralization are temporarily and spatially associated with each other, their possible genetic links are still unclear. To delineate the relationships between the two types of ore mineralization, we carried out in-situ geochemical and S-Pb isotopic analyses on sulfides from the two spatially associated deposits, i.e., the Wangpingxigou Pb-Zn and Donggou porphyry Mo deposits in the ore district.
