摘　　要：哲北农场-联合屯堡一带多金属矿化区位于内蒙古通辽扎鲁特旗西北部,大地构造位置地处华北板块北部陆缘增生带上,成矿地质条件优越。通过地质勘查、物化探测量,结合槽探、钻探验证,认为区内矿(化)点主要赋存于上侏罗统满克头鄂博组及中二叠统哲斯组的蚀变带内,其中上侏罗统满克头鄂博组酸性火山岩是主要成矿地层,成因类型属于热液充填型,岩浆作用为成矿的主导因素,构造作用提供了空间和通道。褐铁矿化、硅化、绿帘石化、孔雀石化等蚀变信息对于后期找矿极为关键。The polymetallic mineralization zone in Zhebei farm-Lianhetunpu is located in the northwest of Zalut Banner,Inner Mongolia.It lies in the northern epicontinental accretionary zone of north China plate and has excellent mineralization geological conditions.Through geological,geophysical and geochemical surveys and trenching and drilling verification,it is concluded that the mineralized points in the area are mainly deposited in the alteration zone of the upper Jurassic Manketouebo Formation and the middle Permian Zhesi Formation,among which the acid volcanic rocks of the Upper Jurassic Manketouebo Formation are the main metallogenic stratum.The genesis is of the hydrothermal filling deposit.Magmatism is the dominant factor,and tectonics provides space and channels for mineralization.As prospecting marks,limonitization,silicification,epidotization and malachitization are critical for later prospecting.
