摘　　要：由于逆冲断层产出构造环和规模的不同，其前缘可以有拆离型、褶皱型、前冲型、反冲型等多种样式；每种样式又可各具不同特征。此外，逆冲前缘还常伴生一些重力构造、盆地构造和不同方向的反转构造。各种构造样式可以相互转化和过渡而共存于同一逆冲带，或发育于不同道冲带中。它们是研究逆冲作用的动力状态、扩展方式和发展阶段的重要依据。Because of the differences of tectonic environments and. scales of development,the frontal zone of a thrust system may be of various types such as decoupling,folding,fore thrust and back thrust.Every type can occur with different characteristics of development which are distinguished by the association of structures such as gravity gliding,foreland basins and different directional inversion structures.All these patterns can be exchanged or transformed and coexist in one thrust frontal zone.They become an important basis for research of the dynamic state,propagation pattern and developmental stage of thrusting.
