| 摘要: |
| 大别山北麓石炭系杨山组是本区唯一的含煤地层,通过分析杨山组野外剖面及钻孔的沉积特点,详述了该区冲积扇、扇三角洲沉积体系的发育特点及其演化规律;探讨了沼泽发育的有利地区,沼泽的形成与沉积体系演化之间的关系;认为杨山组的可采煤层一般都形成在退积型扇三角洲的平原相。 |

| Abstract: |
| The Carboniferous Yangshan Formation is the sole coal-bearing strata in the northern Dabie Mountains.The present paper deals in detail with the development and evolution of the alluvial fan and fan delta depositional systems,potential areas of the swamp develop-ment,the relationship between the swamp formaton and the evolution of the depositional systems in the study area.The conclusion is that the commercial seams within the Yang-shan Formation generally lay down in the retrogradational fan deltaic plain facies. |
