| 摘 要： | 本文在对贵州省织金地区含煤岩系进行成因地层分析的基础上,概括出了受潮汐作用影响的三角洲沉积体系的地方性沉积模式和聚煤特征。将三角洲体系划分为六种地貌单元:上三角洲平原、下三角洲平原、水下三角洲平原、边缘三角洲盆地、边缘三角洲潮汐平原及边缘三角洲沼泽平原。其中三角洲沼泽平原是最好的聚煤场所。

| Abstract: | Based on the genetic stratigraphic analysis of coal - bearing strata, in Zhijin county of Guizhou province, the local sedimentary model and coal-accumulating features of tide - modified delta system are established. The delta system may be classified into six types of geomorphic units: upper deltaic plain, lower deltaic plain, subaqueous deltaic plain, marginal deltaic basin; marginal deltaic tidal plain and marginal deltaic swamp plain. The marginal deltaic swamp plain is an excellent place for coal-accumulation. |
