Re-Os isotopic dating of molybdenite from Dajishan tungsten deposit in Jiangxi Province
摘要
Abstract
Located in the Nanling metallogenic belt of Jiangxi Province, the Dajishan tungsten deposit is a famous large-size tungsten deposit. Precise Re-Os isotopic dating of molybdenite from the Dajishan tungsten deposit was carried out, which yielded an isochron age of (161.0±1.3) Ma. This age is interpreted as the formation age of the molybdenite, representing the formation period of the Dajishan quartz-tungsten type deposit, I.e., the ore deposit was formed in Early Yanshanian period. The precise dating provides convincing basic reliable data for further study of the ore deposit, and also suggests that the period of 170~150 Ma was an important period for tungsten formation in South China.关键词
