界于东经 10 8°30′～ 110°,商丹带 -勉略带 (或大巴山带 )之间的山柞旬 -安康构造带是在古生代 -三叠纪南北向裂陷 -裂谷板内海相沉积盆地基础之上转化形成的 型造山带 ,它与东、西两侧的武当 -商南带、佛坪 -汉南带的组成、结构均不相同。南秦岭的山柞旬 -安康带开始从南向北以及后来再自北向南的两次逆冲推覆所形成的构造格局 ,与目前都认为该区是从北向南指向四川盆地的滑脱—逆冲式的薄皮构造模式是完全不同的。笔者还简要讨论了 型造山带的基本特征
The Yasunan-Ankang tectonic belt between the Shangdan-Mianle belt (or the Dabashan belt), which lies between 10 8 ° 30 ’and 110 ° East longitude, was formed during the Paleozoic-Triassic north-south rift-rift plate The formation of the orogenic belts on the basis of the intracontinental sedimentary basins is different from the composition and structure of the Wudang-Shangnan belt and the Foping-Hannan belt on the east and west sides. The tectonic structure formed by the two thrusting of the Anqin belt that started from south to north and then from north to south in the south Qinling Mountains is now considered to be the slippage and inversion of the Sichuan Basin from north to south Chong-style thin-skin construction model is completely different. The author also briefly discussed the basic characteristics of the orogenic belt
