摘　　要：甲查铅锌矿是大兴安邻得尔布干成矿带上的一个大型铅锌矿床,矿床主要是受断裂构造的控制。研究表明,该区中、新生代以来经历了印支期、燕山期和喜山期三期构造运动。成矿由两个中心和六组构造体系组成,两个中心点是成矿的源泉,构成了矿床的高温内带,也是中低温矿物的载体。北西-南东向应力挤压形成了甲查矿区的基本构造格架,伴之而生的断裂构造与后期断裂叠加,是主要导矿、容矿空间。JiaCha Pb-Zn deposit is a large deposit in Deerbugan metallogenic belt,and controlled by fracture structure.The area has experienced the Indosinian,Yanshan and Xishan tectonic movements,and the mineralization is composed of two centers and six sets of tectonic systems.The two centers are the source of mineralization,which constitute the high-temperature inner zone of the deposit and the carrier of medium-low temperature minerals.North west-south east to stress extrusion formed a mining area's basic tectonic framework,accompanied by superposition of late fault and fracture,the ore is the main ore guide the space.
