摘　　要：大厂锡多金属矿田由西向东分为三个带,东、西部为锡石-硫化物矿带,中部为矽卡岩型锌铜矿带。三个矿带在水平方向上具有明显的不对称,在矿物组合和矿体产出形态上相差也较大,通过对构造形态的空间分析以及成矿流体物理化学性质的比较,阐明大厂矿田成矿分带特征,并解释了不同矿带在垂向上的矿体形态差异。Dachang tin-polymetallic deposit is located in the middle of Nandan-Hechi metallogenic belt,which is one of the famous tin mine in the world.There are three mineralized zone in the ore field from west to east,which is tin-polymetallic belt in the west and east,the Skarn type zinc-copper ore deposit in the middle.They are obviously asymmetric on horizontal direction,and also have greatly different on mineral assemblages and orebody shape.By analyzing the structural configuration and comparing physicochemical property of ore-forming fluid in each metallogenic zoning,it illustrates metallogenic zoning characteristics in Dachang ore field and interprets the orebody shape differences in vertical on different ore belt.
