The Upper Permian reefs of South China are last reefs of the Рaleozoic
Subject of research. The upper Permian reefs of the Yangtze block of southern China are considered. Among them there are two species which differ in location in the basin and the nature of the internal structure.Methods and results. On the basis of geological and lithological methods of research it...
