“三湾运动”是黄汲清、徐克勤(1936)创建的。近年来,它的存在有三种看法:1.轻微的褶皱运动;2.大有问题的褶皱幕;3.假整合。 一、“三湾运动”上、下盘地层的地质时代 所谓造山幕或褶皱幕,是依据两套地层间的角度不整合关系建立起来的;一般来说,上、下盘地层的产状、接触关系、岩性、岩相、构造形态,以及古生物面貌等都不相同。关于“三湾运动”上、下盘地层的地质时代问题,黄汲清等认为均属早侏罗世;李英鉴等(1959)
The “Three-Bay Movement” was created by Huang Jiqing and Xu Keqin (1936). In recent years, its existence has three kinds of views: 1. Slight fold movement; 2. Great problem pleat curtain; 3. False integration. 1. In the “Three-Bay Movement”, the so-called orogenic curtain or fold curtain in the geological era of the lower plate strata was established from the angle of the unconformity between the two strata; in general, the shape of the upper and lower strata , Contact relationships, lithology, lithofacies, tectonic forms, and paleontological features. On the “Three-Bay Movement”, the geological conditions of the lower plate strata, Huang Jiqing and other think are early Jurassic; Li Yingjian (1959)
