摘要

The Zhaiwa Mo deposit in the Xiong’er Mountain of western Henan Province is a quartz vein-type molybdenite deposit newly discovered in the hypometamorphic rocks of Archean Taihua Group. In order to determine the age of the deposit, the authors selected pure molybdenite grains from 10 quartz molybdenite vein-type ore samples for Re-Os isotopic dating. It is suggested that the ore-forming process of the Zhaiwa Mo deposit occurred in an extension-broken setting of North China Craton at the late stage of Paleoproterozoic and hence the deposit might be the oldest Mo deposit in China.
