SHRIMP zircon U-Pb and molybdenite Re-Os isotopic dating of the tungsten deposits in the Tianmenshan-Hongtaoling W-Sn orefield, southern Jiangxi Province, China, and geological implications

► High-precision ages of W-Sn ores and related granites are Late Jurassic with a peak at 150 to 160 Ma in southern Jiangxi. ► There is none, or only slight (1-6 Ma), time difference between W-Sn mineralization and parent granite crystallization. ► Quite low Re contents in Molybdenites suggest continental crustal provenance of the ore metals in tungsten deposits. ► The major W-Sn metallogenesis in southern Jiangxi took place in Jurassic intraplate extensional setting.
