摘要
昆秦接合部造山带逆冲滑脱构造,发育在造山带苦海—赛什塘构造混杂带南侧,由一系列断面南东倾,规模大小不一的韧性逆冲断层、韧脆性叠瓦状逆冲断层及同斜紧闭褶皱、平卧褶皱、逆掩断层构成多层次逆冲滑脱构造带。它的形成及演化奠定了昆秦接合部造山带复杂的构造结局,标志着昆秦接合部造山带印支期大规模陆内造山活动的结束。
The thrust-decollement belt in the orogenic belt of junction part of Qinling and Kunlun is developed on the south side of Kuhai-Saishitang tectonic melange belt.It is constituted by a series of ductile thrusts with fault plane dip to southeast and various scale, ductite-brittle imbricate thrusts,isoclinal folds,recumbent folds,and overthrusts.Its for- mation and evolution have established the complex tectonic pattern of the orogenic belt in junction part of Qinling and Kunlun marked the end of the large scale inter continental oroge- neses.
