| 摘 要： | 本文概述了７０年代中期以来逆冲推覆构造研究的几个方面，指出逆冲推覆构造广泛产出于不同大地构造单元，今后应注意造山带内尤其是活动性高的地台上这类构造的研究。台阶式结构是逆冲构造的基本型式，但对各种模型应采取分析态度。文章分析了与逆冲推覆系相关的褶皱构造及其产出关系。逆冲推覆构造常呈一定型式产出，以隆起构造为中心的背冲和以构造拗陷为中心的对冲是具有普遍品格的模式。挤压性推覆与伸展滑覆常密切伴生，并与构造热隆作用相关，常常表现为推覆→侵入→滑覆的规律性顺序。笔者最后提出了这类构造今后研究的意见。

| Abstract: | The research of thrust-nappe tectonics since the middle epoch of 1970s is re-viewed.It is suggested that the thrust-nappes occur extensively in various tectonic ele-ments and indicated emphatically that these structures in orogen,particularly those in ac-tive platform should be studied seriously.Stepping style is the basic pattern, however,various models of the structures must be analysed comprehensively,The relationship ofthe thrust-nappe system with the associated folds is analysed.Depending on the geologicalsetting,thrust-nappes occur with various patterns, and fan-shaped thrust structure refer-ring to uplifting and ramp-shaped thrust structure referring to depression are the dominantstyle being of universal significance,Compressive nappes usually are closely associatedwith extensional gliding nappes,and are controlled by thermal uplifting.The sequence oforigin is ordered as follows:thrust-nappe→igneous intrusion→gliding nappe. In theend of the paper the author proposes some remarks for the further research of thrust-nappe tectonics. |
