| 摘 要： | 本文对前龙门山区彭县推覆构造进行了详细研究,在推覆体内部划分出若干不同的构造带,强烈压缩变形的白水河断裂带为其“根带”。它们主要是旱第三纪末的陆内俯冲挤压导致的褶皱-逆冲作用以及随后的重力滑动作用形成的。推覆体在滑移过程中发生变形,并对原地岩系的构造进行改造。

| Abstract: | In the pre-Longmenshan range of the northwest margin of the Sichuan basin, the structure within the nappes of the Pengxian nappe structure can be classified into several structure belts. The root zone of the nappes is the Baishuihe fault zone which has been strongly compressed and deformed. The nappe structure was formed by the fold-thrusting resulting from the incracontinental subduction and compression at the end of, mainly, the early Tertiary Period, and subsequently by the gravitational gliding. During the gliding process, the nappes was deformed and the structure of the autochthonous rocks was transformed. |
