摘　　要：初步查明测区侵入岩时空分布特点及形成构造环境。解析德母拉岩带、阿扎贡拉岩带,按花岗岩类的成分和结构演化序列,将测区花岗岩划分为三缅村、竹瓦根2个序列及7个单元,归于侏罗纪、白垩纪两大岩浆活动期。We have a preliminary grasp of the characteristics of time - space distribution and the structural environment of formation of intrusive rock in this area. The Demula rock zone and Azagongla rock zone have been analysed. The granite rocks in this area have been divided into Sanmiancun and Zhuwagen 2 series, 7 units and Jurassic, Cretaceous 2 magmatic periods.
