摘　　要：八家子东部钼矿床为八家子多金属成矿带的一部分，位于锦西一青龙断裂南侧。矿床为斑岩型钼矿床，区内钼矿主要产于花岗斑岩与其他岩体的内接触带以及断裂带附近，外接触带次之。热液蚀变较为强烈，硅化、云英岩化与辉钼矿化关系最为密切。钼矿化对于地层并没有明显的选择，燕山期岩浆活动和构造是该区钼矿的主要控矿因素。该多金属矿床距侵入体具有明显的分带性。The east Bajiazi molybdenum deposit is a part of the Bajiazi polymetallic metallogenic belt, located in the south of Jinxi-Qinglong fault zone. This ore deposit is porphyry molybdenum, and mainly hosted near fault zone and the inner contact zone between granite-porphyry and other rock mass. Hydrothermal alteration is relatively strong here, and silicification and greisenization are most closely connected with the molybdenite mineralization. Molybdenum mineralization is no obvious selectivity for stratum, and magmatic activity and structure in yanshanian are the main ore-controlling factors. The intrusive body of this polymetallic deposit has obvious zonation.
