内蒙古东乌珠穆沁旗格尔楚鲁银矿构造特征及找矿方向
|
摘要
格尔楚鲁银矿位于内蒙古东乌珠穆沁旗NE向100 km,大地构造位于天山—兴蒙造山带南缘褶皱带,查干敖包—阿荣旗深大断裂带以北,属于二连—东乌旗多金属成矿带。区域成矿条件优越,在该区域已发现了索纳嘎银多金属矿、朝不愣多金属矿、萨麦钨矿等矿床,但由于草原覆盖,区内地质工作程度较低。通过对东乌旗区域构造特征及格尔楚鲁银矿矿区地质构造特征进行研究,认为区内成矿受NE向与NNW向断裂构造带组成的"丰"字型构造控制,下一步找矿方向为"丰"字型构造的断裂交汇部位。
Geerchulu silver deposit is located 100 km to the north east of in Dong Ujimqin Banner in Inner Mongolia.The geotectonic location is the fold belt of the southern margin of Tianshan-Xingmeng orogenic belt,north of Tsagaan Ovoo-Arun Banner deep fault belt,it belongs to Erenhot-Dong Ujimqin Banner polymetallic metallogenic belt.The regional metallogenic geological conditions are good,Suonaga silver polymetallic deposit,Chaobuleng polymetallic deposit and Samai tungsten deposit are found in the area.However,due to grassland coverage,degree of geological work in the area is relatively low.Through the study of regional tectonic characteristics of Dong Ujimqin Banner and geological tectonic characteristics of Geerchulu silver mining area,it is indicated that metallogenic activities in the mining area are mainly controlled by "Feng" type structure composed by NE direction NNW direction fault tectonic belts,the intersection part of fault tectonic belts of "Feng" type structure is the further prospecting direction of the mining area.
