1975年和1976年,作者和安徽省地质局332队宿立先、黄清涛同志先后观测了皖南的铺岭组和井潭组剖面,并将部分资料作过初步介绍。1977年作者又到现场观测和收集了牛屋组、板桥组、漳前组的有关资料。本文就是根据已收集的初步资料整理而成。研究地区元古界变质杂岩包括休宁组以前的地层。安徽省区域地质调查队将它分为漳前、板桥、木坑(环沙)、牛屋、邓家和井潭(铺岭)六个组分别归于震旦系和前震旦系(表1)。 In 1975 and 1976, the authors and the 332th team of Anhui Provincial Bureau of Geology, Su Lixian and Huang Qingtao successively observed the profiles of the Puling Formation and the Jingtan Formation in southern Anhui Province, and introduced some of the data preliminarily. In 1977, the author went to the site to observe and collect the information of Niuwu, Banqiao and Zhangqian. This article is based on the preliminary information collected. The Proterozoic metamorphic complexes in the study area include the previous strata of the Xiuning Formation. Anhui Province Regional Geological Survey team divided it into Zhangqian, Banqiao, Mukeng (Huansha), Niuwu, Dengjia and Jingtan (Puiling) six groups were attributed to the Sinian and the former Sinian (Table 1 ).
