| 摘 要： | 邢家山大型钼钨矿床位于胶东栖霞-蓬莱-福山金及多金属成矿区东部,矿床主要赋存于晚侏罗世二长花岗岩外接触带的变质地层中,倒转向斜分布区是钼钨成矿有利部位。幸福山岩体为成矿母岩,粉子山群的碳酸盐岩既易交代成矿亦形成了屏蔽层,NW向张扭性断裂导矿,层间裂隙、节理和矿物间隙沉淀成矿。钼钨矿化作用与矽卡岩化、钾化、硅化密切相关,矿床工业类型属矽卡岩型-斑岩型,成因类型属于岩浆期后热液矿床,矿石建造属钨钼建造,该成果对在胶东地区寻找同类型钼矿床具有重要意义。

| 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. |
