摘要
湘鄂西及邻区二叠系茅口组顶部广泛发育了岩溶角砾岩,并形成了一个分布范围广阔的不整合面,该不整合面特征在各地存在明显差异,其上覆孤峰组与龙潭组也存在不同程度的缺失。东吴运动为两幕式构造运动,上述现象正是东吴运动Ⅰ幕、Ⅱ幕在不同地区的沉积学响应。
Abstract
The karst breccia extendedly developed on top of the Permian Maokou Formation in the western Hubei-Hunan and neighboring areas.So that,it forms a large unconformity.The unconformity appears differences in different areas.The Gufeng Formation and Longtan Formation,overlying the unconformity,are absent in different degrees in those areas.So,the Dongwu Movement can be subdivided to two episodes in this paper.The above phenomena indicate the sedimentary response to the two episodes of the Dongwu Movement.
