The origin of the Quemocuo carbonate-hosted Pb-Zn deposit in the Sanjiang Tethyan Belt, SW China: Constrained by Sm-Nd isochronic age and Sr-S-Pb isotope compositions

The newly discovered Quemocuo Pb-Zn deposit (7.1 Mt of sulfide ores, grading 1.65–7.17 wt% Pb and 1.13–5.7 wt% Zn) is located in the Tuotuohe area of the Sanjiang Tethyan metallogenic belt, SW China. The stratiform and veined ore body is hosted in the limestone of the Upper Permian Labuchari Formation and occur along the NE-trending fault. Four main mineralization stages are distinguished as follows: (i) pyrite + calcite + quartz, (ii)...
