The Jinzhuping molybdenum-polymetallic deposit from Shangrao, Jiangxi province is located in Lizi volcanic basin, which is one of volcanic rock area in the northern Wuyi and in which larger-scale of molybdenum-polymetallic mineralization was found.
The Jinzhuping mine is close situated to the center of the Basin and molybdenum-polymetallic ore bodies mainly occurred within contact zone between underlying granite and overlaid volcanic rock, following the shape of the zone. Re-Os isotope dating for molybdenite from the contact zone yield an isochron age of （135.5 ±5.7） Ma with MSWD = 16, which indicates that the mineralization took place at the Cretaceous. The ore body occurred adjacent to the granite, thus it is inferred that mineralization stage is syngenetic or slightly later than emplacement of the granite, suggesting that mineralization of Mo, W, Pb, Zn and Ag was closely related to emplacement of the Yanshan period granites, and providing a new model for prospecting intrusive-related resource inside the volcanic rocks.
