摘　　要：喀喇沁旗位于华北地台北缘中段槽台交界处台区一侧，ＥＷ向超岩石圈断裂与ＮＥ（ＮＮＥ）向新华夏构造体系交汇处．境内晚太古宙含金绿岩建造、元古宙浊积岩建造，以及燕山期金铜系列花岗岩广泛出露．中生代地台活化过程中造成的含金结晶基底重熔及构造活化作用使该区广泛发育显生宙花岗岩建造全矿床、绿岩建造金矿床和浊积岩建造金矿床．根据活化成矿理论估算的全旗金矿资源总量在２５０ｔ以上。Kalaqin County is situated in the middle part of the north fringe of Hua-Bei platform where the geosyncline meets the platform, and also the transcending lithosphere fracture of EW trend and the new Hua-Xia structural system converges.The whole area of the county belonged to goldbearing greenstone formation in late archean era and turbidite formation in proterozoic era with granite of gold-copper series of Yanshan Period widely cropped.The sold-bearing crystaline basement re fusion resulted from the platform activation in mesozoic era and the activation of structure enabled the wide development of gold deposits of granite,greenstone and turbidite formations since the existence of life had taken place on the earth. According to the theory of mineralizing activation,the total gold of the resources in the whole county are more than 250 ton
