试论局限台地碳酸盐岩型含煤建造--桂中马滩一带合山组的某些沉积特征

上二叠统合山组是桂中地区主要含煤地层,它在马滩一带沿红水河出露特别完整。合山组是较为少见的局限台地碳酸盐岩型含煤建造,研究它的物质成分、沉积结构和构造、生物化石、沉积相类型、垂向层序及沉积模式等,为探索含煤建造的形成条件和分布规律提供了必要资料。这一研究课题,无论在沉积学理论上或成煤理论上都有重要意义。笔者先后于62年、78-81年多次到野外进行观察,82年又补充了一定的野外工作。其中78-81年广西150煤炭勘探队参加了野外工作。

THE COAL-BEARING FORMATION OF CARBONATITE TYPE IN RESTRICTED PLATFORM-SOME SEDIMETARY CHARACTERISTICS OF HESHAN FORMATION IN THE MATAN REGION OF CENTRAL GUANGXI

The Upper Permian Heshan formation,the most industrial important Coal-bearing stra-ta in central Guangxi, is a main source of industrial coal.The Heshan formation iS coal-bearing formation of carbonatite type of re-stricted platform. It belongs to a special type. To study it in detail is of great significance to sedimentology, the theory of coal-formation and to the industrial production.
