According to geological features, geochemical characteristics and geochronology, the endogenic molybdenum deposits in the region are divided into porphyry type, contact-metasomatic hydrothermal type and medium-high temperature hydrothermal type. The research results show that porphyry deposits are associated with high-potassium calc-alkaline granitic magmas, while contact-metasomatic hydrothermal deposits are related to calc-alkaline granitic magma and the nature of host rocks. Metallogenic materials possess the characteristic of crust-mantle mixing source. The Mo mineralization in the study area mainly occurred in 195~165Ma and 115~110Ma. The corresponding geodynamic mechanisms responsible for the Mo mineralization in different times may be closely related to the subduction of paleo-Pacific plate and Izanagi plate towards the Eurasia continent, respectively. %K Endogenic Mo deposit types %K Ore-forming episodes %K Geodynamic setting %K The eastern edge of Xing-Meng orogenic belt
