摘　　要：结合１∶５万区调工作，经过对安徽境内的梅山群和河南境内的杨山煤系的系统剖面观察、研究与对比，认为梅山群相当于杨山煤系中上部（胡油坊组、杨小庄组、灰冲组）的东延部分，其时代归属于晚石炭世—早二叠世。同时对梅山群的变质作用、糜棱岩的形成期次、“前寒武纪岩块”According to the surveying and studying of sections and comparing Meishan Group in Anhui Province with Yangshan coal bearing series in Henan Province, the Meishan Group is considered as the eastward extension of the middle and upper parts of the Yangshan coal bearing series and its time is the Late Carboniferous Early Permian. Some structural questions, such as metamorphism of Meishan Group, forming stages of mylonites and Precambrian massif, are discussed in the paper.

关 键 词：梅山群 晚石炭世 地质构造 煤系 煤矿床
