龙门冲

本文以L14、L55地震大剖面为主，论述了龙门山逆冲推覆构造带北段的结构、模式、形成期、推覆距及油气远景。

Mainly based on seismic profile L_ ( 14 ) and L_ ( 55 ), the authors discuss the texture , mode , formation time , thrusting distance and oil and gas prospects of the northern sector of thrusting nappe structure of Longmen Mountains .

同时，估算龙门山逆冲推覆体在各个不同时期的抬升高度和抬升速率。

The thrusting and uplifting rates of the Longmenshan thrust nappe are estimated for various geologic times .

扬子地台西北缘前陆逆冲带（即龙门山逆冲带）的形成和演化控制着扬子地台内部及其西北缘煤炭资源的聚积和赋存。

The accumulation and occurrence of coal resources in Yangtze platform and its northwest margin are controlled by the formation and evolution of foreland thrust belt in its northwest margin .

川东北地区位于扬子地块的北缘，其北与秦岭造山带、西与龙门山逆冲带、东南部与华南褶皱系毗邻。

Northeast Regional Of Sichuan lies in the north of Qingling and Yangzi Block , abus Longmen mountain thrust nappe tectonics in west , abuts South China fold systerm in Southeast .

由于晚三叠世以来龙门山的逆冲推覆，使得扬子台地西缘中二叠世出露具有不完整性。

As the thrusting of Longmen Mountain towards southeast since late Triassic , the middle Permian strata in the western margin of Yangtze platform are not exposed completely .
