Abstract
Tectonically,the northwestern Yunnan area may be separated into 3 first-order tectonic units,10 second-order tectonic units and 25 third-order tectonic units. From west to east,the above-mentioned 10 second-order tectonic units consist dominantly of the Dulongjiang arc-basin system,Bingzhongluo block,Mode suture zone,Chongshan block,Lancangjiang volcanic arc,Lanping block,Yunling continental-margin arc,Jinshajiang suture zone,Xianggelila block and Garze-Litang arc-basin system. The boundary faults are assembled,from west to east,by the Gaoligongshan fault, Bangdang fault, Fugong fault, Biluoxueshan fault, Jicha fault, Deqen-Xuelongshan fault, Yangla-Dongzhulin fault, Jinshajiang fault, Xianggelila fault and Sanjiangkou fault. The classification scheme proposed in this paper represents the new progress and refinement of the tectonic units in northwestern Yunnan.关键词
