摘　　要：在对研究区区域地层、构造、岩浆岩以及矿体地质特征认识的基础上,从岩浆岩、地层、构造和地球化学场四个方面对研究区的控矿因素进行了分析,从而认为断裂构造是本矿床的主要控矿因素。断裂构造作为金矿床形成和空间分布的主要控制因素,不仅提供了成矿流体运移通道,而且还提供了矿体就位空间,这一点也同时在地球化学异常显示上得到证明。On the basis of understandings of regional strata, structures and magmatic rocks as well as features of ore bodies in the study area, this paper made an analysis of ore-control factors in terms of magmatic rocks, strata, structures and geochemical fields and concluded that firing structures are the major ore-control factor, which, as the controller of gold ore deposit formation and its spatial distribution, not only provided a passage for ore-forming fluid to move within and also a space for ore body to emplace in, which is reflected in the show of geochemical anomaly.
