SHRIMP U-Pb dating of zircons in mineralized porphyry of the Dongyuan W deposit in Anhui province and its Geological significanceof the newly found Dongyuan W-Mo deposit in Huangshan area, Anhui province
Abstract: Dongyuan W deposit is a newly found large-scale scheelite deposit, which is also the biggest one in south of the Anhui province. The found of the Dongyuan W deposit set the direction for mineral exploration and laid groundwork for further exploration. This paper preliminarily analyzed regional structural background and metallogenic controlling factors, firstly obtained U-Pb age of zircon by using SHRIMP. The results showed that ore-forming age of the granite-porphyry in the Dongyuan Porphyry W Deposit is 148.6±1.8Ma （N=16, MSWD=1.5），and the granite porphyry rock was product of late Jurassic magmatic movement. The results also suggested that the regional tungsten mineralization might extend from South China to the Middle and Lower Reach of the Yangtze River.
