引言涟邵地区,包括湖南中部湘乡、涟源、新化、双峯、邵东、新邵、邵阳、隆回、武岗等县的全部或部分区域,二迭系在本区分布甚广,并组成了十余个较完整的向斜。由于本区适处于华南地块的中心,具有华南二迭纪沉积的一定代表性;加上二迭系在这里出露比较良好,构造在有些地点还十分简单,容易进行地层的观察和研究;更因为该系上部是一个重要的合煤地层,所以,将涟邵地区二迭系加以分层和对比,是有很大意义的。
Introduction The Liantiaoshan area covers all or part of the counties in central and southern Hunan, including Xiangxiang, Lianyuan, Xinhua, Shuangfeng, Shaodong, Xinshao, Shaoyang, Longhui and Wugang counties, And formed more than ten more complete syncline. Since this area is located in the center of South China block, it has certain representativeness of the sediments of the Second Permian in South China. Coupled with the fact that Permian is relatively well exposed here, the structure in some places is also very simple and easy to observe and study stratigraphy. Because the upper part of the department is an important coal seam, it is of great significance to stratify and contrast the two sedimentary systems in Lianshuo.
