梅山群为一套浅变质岩系，分布于大别山北麓安徽省金寨县—河南省商城县一带。据１∶５万区调新资料，讨论了梅山群的含义、岩石组合、变质变形、区域对比、时代归属等方面的一些看法。认为梅山群不同于佛子岭群和石炭系，岩石组合、变质变形特征上存在着明显差异。梅山群是位于佛子岭群之下逆掩于石炭系之上的构造岩片。据区域对比分析，梅山群的原岩形成于早古生代
Meishan Group as a set of shallow metamorphic rocks, located in the northern foot of Dabie Mountain, Jinzhai County, Anhui Province - Shangcheng County, Henan Province area. According to the new data of 1: 50000 areas, some opinions on the meanings of the Meishan Group, the rock assemblage, metamorphism and deformation, regional contrast and the ownership of the time are discussed. It is considered that the Meishan Group is different from the Foziling Group and the Carboniferous, the rock assemblage, and there are obvious differences in the characteristics of metamorphism and deformation. Meishan Group is located beneath the Foziling Group, which is underlain by the Carboniferous. According to the regional comparative analysis, the original rocks of Meishan Group formed in the Early Paleozoic
