Tectonic implications from Re–Os dating of Mesozoic molybdenum deposits in the East Qinling–Dabie orogenic belt

The East Qinling–Dabie molybdenum belt is part of a larger East–West trending metallogenic belt in eastern China. Most of the molybdenum deposits occur as porphyry or porphyry–skarn type, but there are also some vein type deposits. Following systematic Re–Os dating of molybdenite from 13 deposits and comparisons with two previously dated deposits, we have recognized that the molybdenum mineralization in the East Qinling–Dabie belt was developed...
