湖南印支运动的研究,始于本世纪三十年代。印支运动是一次强烈的构造运动,它结束了湖南海侵的历史,并奠定了现今湖南构造面貌,使尔后形成的侏罗系或瑞替克-里阿斯统为孤立山间盆地磨拉式堆积。笔者综合分析了已有成果,结合参加湘中石油会战野外观察资料,通过对三叠系重新划分、对比,认为湖南印支期处于由海洋向陆地转变的时期,上三叠-下侏罗统为陆缘海型的淡水一半咸水的碎屑沉积。晚三叠-早侏罗世地壳运动并不十分强烈,除湘东遭受褶皱外,其它地区主要为巨型坳褶,且愈往西愈微弱,湖南现今构造面貌主要为安源前幕所形成。
Research on the Indo-Chinese Movement in Hunan began in the thirties of this century. The Indosinian movement was a strong tectonic movement that ended the history of the transgression of Hunan and laid the foundation for the present-day structural structure of Hunan so that the Jurassic or Reith-Riith formed later would be regarded as the moss of the isolated mountain basin Stacked. The author has comprehensively analyzed the existing achievements and combined with the field observation data in the battlefield of the oil in Hunan Province. Through the redistribution and contrast of the Triassic, the period of the Indosinian Period of Hunan Province is changing from the ocean to the land, the Upper Triassic-Lower Jurassic Detritus sediments of brackish water in continental marginal seawater. The Late Triassic-Early Jurassic crustal movement is not very strong. Except for the folds in the eastern part of Hunan Province, the other parts of the Late Triassic-Jurassic crust are mainly giant colliery folds, and the more the west is weaker. The present-day Hunan-Nanjing tectonic features are mainly formed by the front curtain of Anyuan.
