内蒙甲一查银多金属矿床是由燕山期构造岩浆作用形成的后火山热液脉状矿床。矿体的形态、产状、厚度、品位等完全受控于成矿期断裂的性质及其产状、规模。本文论述了矿区的控矿断裂特征，并指出在进一步找矿中应注意采用构造地球化学方法、追索和寻找活动时间较长、规模较大、成矿期为张剪性或压剪性的NWW、NNW向断裂。
The Inner Mongolia Jiayi Zhayin polymetallic deposit is a post-volcanic hydrothermal vein deposit formed by the Yanshanian tectonic magmatism. Ore body shape, shape, thickness, grade and other completely controlled by the nature of the metallogenic fracture and its production, scale. This paper discusses the ore-controlling faults in the mining area and points out that in further prospecting, we should pay attention to the tectono-geochemical method, recourse and find activities for a long time, large scale, and the metallogenic stage is shearing or compressive shear NWW, NNW fracture.
