Abstract:Xingjiashan large molybdenum tungsten deposit is located in eastern QixiaPenglaiFushan gold and polymetallic metallogenic area in Jiaodong. The deposit mainly occurs in the metamorphic strata of the external contact zone of the late Jurassic adamellite, and the reverse oblique distribution area is the favorable place for MoW mineralization. Xingfushan rock body is the oreforming parent rock. The carbonate rocks of Fenzishan group are easy to metasomatize and form a shield layer. Tensional and torsional faults with the trend of NW are leading ores, and minerals precipitate in interlayer fissures, joints and mineral gaps. The mineralization of molybdenum and tungsten is closely related to skarn, potassic and silicification. The industrial type of the deposit belongs to skarn porphyry type, the genetic type belongs to post magmatic hydrothermal deposit, and the ore formation belongs to W-Mo formation. This achievement is of great significance for searching the same type of molybdenum deposits in Jiaodong area.
