| 摘 要： | 根据岩石学，古生物学，煤岩学，地球化学的研究，对冷水江矿区则水组合煤段的沉积环境进行了详细论述，表明该区为障壁岛－泻湖－潮坪－潮道沉积，运用成因地层分析方法，将含煤段划分为三个成因不同的生长层序，它们分别代表填积－进积－退积过程，同时还详细阐述了各生长层的沉积环境的演化，海水进退的情况，水介质古盐度的变化及聚煤规律最后总结出矿区测水组的成煤模式。

| Abstract: | Based on the study of petrology, palaeoecology, coal petrology and geochemistry, the sedimentary environment of coal bearing member of Ceshui Formation in Lengshuijiang Mine Field is discussed. It is deposits of barrier island lagoon tidal flat tidal channel. By using the method of genetic strata analysis, the coal bearing member is divided into three increment sequence which represent process of aggradation progradation retrograding. The evolutional process of sedimentary enviroment, transgression and regression, change of salinity level of water and accumulation laws of coal seams for every increment sequence are discussed in detail. Finally, the model of accumulation of the coal seams of Ceshui Formation in Lengshuijiang Mine Field is summarized. |
