摘　　要：利用重力、航磁、航电、航空γ能谱、地震测深等多种地球物理资料,对新疆北部的康古尔塔格断裂带深部地质特征进行了探讨。认为该断裂带两侧的地壳结构有较大差异,北侧地壳为二层结构,上地壳中发育有高密度、强磁性、高速度的镁铁质岩;南侧地壳为三层结构,同时有低速度层发育。康古尔塔格断裂带是划分准噶尔与塔里木两大板块的一条重要界线。The deep geology of the Kanggur Tag fault zone in northern Xinjiang has been studied according to the data obtained using many geophysical means such as gravity,airborne magnetic and airborne electric surveys, airborne γ energy spectrum analysis and seismic sounding.There is appreciable difference in crustal structure on the two side of the fault zone:the crust on the northern side has a two-layer structure and there occur very dense,strongly magnetic and high-velocity mafic rocks;whereas the crust on the southern side has a three-layer structure and there is also a low-velocity layer.The Kanggur Tag fault zone is an important boundary between the Junggar plate and Tarim plate.
