摘要
推覆构造体系是由几条逆冲断裂带及其逆冲席、逆冲片组成,主干断层与次级断层组成叠瓦式构造。本文对研究这四条主干道冲断裂带及其间的逆冲席、前缘区的特征进行了详细描述,并通过野外观察和室内泥。模拟试验研完了推覆构造的发展演变及形成机制,指出其前缘三角区是最有利的油气勘探区。
The structural system of nappe consists of several overthrust fracture belts, thrust sheets and thrust slices, and master fault and secondary fault form an imbricate structure. This paper desofibes in detail the characteristics of four master thrusts, and thrust sheets in between and frontal zone, and studies the development and formation mechanism of the thrust nappe by field observation and by simulated test of mud materials indoor. It has been pointed out that the frontal triangular zone is the most favourable exploration region of oil and gas.
