摘　　要：内蒙古自治区以阿拉善右旗—乌拉特后旗—白云鄂博—化德—赤峰为界,划分为华北陆块和兴蒙造山系两大构造单元。由于多期次的构造变动和频繁的岩浆活动影响,致使全区形成极为复杂的构造格架,岩浆活动表现为多旋回、多期次的特点,特别是华力西期—燕山期大规模的酸性、中酸性岩浆岩分布广泛,是形成金矿产的重要因素。全区已探明矿产地218处,其中大型矿床10处,中型矿床27处,小型矿床62处,矿（化）点119处。划分了18个矿产预测类型,确定5种预测方法类型。圈定最小预测区515个,其中A级最小预测区86个,B级最小预测区175个,C级最小预测区253个,100~2 000 m以浅预测资源量913 t。全区共圈定13个金矿找矿远景区,并对其进行了资源潜力分析。The Inner Mongolia Autonomous Region,with a vast territory,bounded by the Alashan Right Banner- Urad Rear Banner- Bayan Obo- Huade- Chifeng area,can be divided into two tectonic units,i.e.,the North China Block and Xing- Meng Orogenic System.The multi-stage tectonic movements and frequent magmatic activities resulted in complex tectonic framework in the region.The magmatic activities in the region are featured by multiple cycles and multiple stages,and the widely-distributed Hercynian-Indosinian acidic and intermediate-acidic magmatic rocks exert a critical role on gold mineralization.Till now,an overall of 218 proven mineralproducing areas have been discovered in the region,including 10 large deposits,27 medium-sized deposits,62 small deposits and 119 ore occurrences.A total of 18 mineral prediction types and five prediction methods have been determined.We have delineated 515 minimum prediction areas,including 86 A types,175 B types and 253 C types,and estimated the resource amount at depth of 100 ~2 000 m to be 913 t.In addition,13 gold ore prospective areas were delineated,and their resource potential was analyzed.
