中国南方二叠纪聚煤规律的探讨

本文讨论了中国南方二叠纪含煤岩系沉积特征、沉积类型、含煤性及聚煤规律。着重探讨了古构造及岩相古地理与聚煤作用的关系。三角洲平原及潮坪——泻湖是中国南方二叠纪最重要的聚煤环境。富煤带往往分布于次级坳陷或隆起与坳陷的斜坡部位,同时也受同沉积断裂的制约。

On the Permian Coal Accumulating Law in South China

This paper discusses the sedimentary characters, sedimentary types, coal-bearing properties and coal - accumulating law of the permian coal-bearing series in South China, especially the rela- between the paleostructures and the lithoface paleogeography and the coal - accumulation. In South China, in the Permian Period, delta plains and tidal flat-lagoons are the most important coal-accumulating environments whose coal-rich belts are distributed in the subdepressions or the slopes between the uplifts and depressions, and meanwhile controlled by syn- sedimentary faults.
