..., the metallogenesis of this province has long been a matter of debate. In this study, molybdenite Re-Os, pyrite Re-Os, and Rb-Sr isotope methods are used to date the Yinachang and E’touchang Fe-Cu deposits in the central part of this province. Fine-grained (<0.1 mm) molybdenite occurs as veinlets along bandings...
