摘要
贵州扬子准地台燕山期形成的褶皱主要由东西向、南北向、北西向、北东向和北北东向的褶皱先后叠加而成。不同地区,各方向褶皱表象明显程度不同,各方向褶皱主体形成的先后顺序依次为东西向,北西向、南北向和北北东向、北东向。叠加褶皱存在跨褶和推褶两大类。跨褶中横跨、斜跨和重褶三种形式都有。推褶中也有斜推和横推两种形式。
The folds of Yangtze paraplatform formed in Yanshan period in Guizhou were mainly superim- posed early and late in the directions of EW,SN,NW,NE/,and NNE,etc. In different areas,the folds in different directions obviously show different degrees. Tne main bodies of the folds in different directions show early or late sequences which are in the directions of EW, NW, SN, NNE and NE,etc. The superimposed folds can be divided into bestrided folds and pushed folds,with transatlantic folds,slanting folds and duplicated folds existinfg in the bestrided folds and slanting folds and transatlantic folds existing in the pushed folds
