S-Pb isotopic geochemistry of Xiuwacu magmatic hydrothermal Mo-W deposit in Zhongdian area ，NW Yunnan :Constrains on the sources of metal. Acta Petrologica Sinica ， :3171 － 3188 31 (11) Abstract A Late Cretaceous Mo-Cu-(W)metallogenic belt was found in the Zhongdian area ，southern portion of the Yidun Arc ， which is not only distinguished from contemporary Sn-Ag-Pb-Zn mineralization in the northern Yidun Arc ，but also different from the Late Triassic porphyry Cu mineralization in the same area. The reason why the metals of that above mineralization in the Yidun Arc are different remains unclear ，as a lacking of researches on the sources of ore-forming materials of those Late Cretaceous deposits in the Zhongdian area. The Xiuwacu deposit is a large-scale Late Cretaceous Mo-W deposit in the Zhongdian area ，with ages ranging from 85Ma to 83Ma. Three stages of the Late Cretaceous granites deve
