Abstract

Abstract

To obtain the exact metallogenic age of Xiaoxi'nancha copper-gold deposit, the quartz-molybdenite vein newly discovered in the Beishan ore block is studied and dated by Re-Os isotopic dating of molybdenite. The quartz-molybdenite vein is parallel to adjacent lode copper-gold ore bodies, which indicates that both are controlled by the common structure system. The dominant metal minerals in molybdenum ore is molybdenite which is occasionally cut by later pyrite and chalcopyrite. Due to the intergrowth of different metal minerals, the lode molybdenum mineralization in Xiaoxi'nancha deposit is clearly earlier than major copper-gold metallogenic stage. Accordingly, it can be concluded that the lode molybdenum mineralization belongs to early metallogenic stage of copper-gold mineralization. Six samples of molybdenite for Re-Os isotopic dating are analyzed. The model ages vary from 109.2±3.4 Ma to 110.8±4.0 Ma, average 109.9±3.9 Ma, and a good isochron age of 111.1±3.1 Ma. These results are consistent with new isotopic dating of granitic intrusions related to copper-gold mineralization in this deposit. It indicates that the large copper-gold mineralization took place in late Yanshanian periods and both the granites and copper-gold mineralization were generated under extensive active continental margin resulted from the obliquely subduction of Pacific Ocean slab. Moreover, petrological & geochemical characters, isotopic dating of ore-forming intrusions as well as low content of Re in molybdenite demonstrate that granitic intrusions and copper-gold mineralization were derived from deep source, mainly upper mantle.
