摘　　要：运用节理等密图、节理玫瑰花图分析了矿床在成矿期的主应力,对比区域构造演化历史,对矿床发育的断裂和节理进行了分类,确定了控矿断裂的级别和期次并与控矿节理相互配套,分析了矿床的构造控矿机制与成矿规律。分析认为成矿期的主应力方向为NNE-SSW,矿（化）体主要以雁列脉状矿（化）体的形式产出,控矿断裂的级别主要分为3级,成矿可划分为3个阶段。结合成矿地质背景和矿床地质特征,指出了今后找矿方向。The main stress in the mineralization period of the deposits is analyzed by using the joint contour diagram and the joint rose diagram.Compared to the regional tectonic evolution of the deposit,the fracture and the joint of deposit are classified.Then,the levels and time of the ore-controlling faults are determined and matched with the ore-controlling joints.Meanwhile,the ore-controlling mechanism of deposits and its metallogenic law are analyzed.The analysis shows that the main stress in the mineralization period is in the direction of NNE-SSW.The deposit is mainly grown in the form of echelon vein ore-body.The ore-controlling faults are divided into three levels,and the mineralization is classified into three stages.Combining with the geological background of mineralization and the geological feature of the deposit,the ore prospecting direction is proposed.
