| 摘 要： | 本文依据对冷水江矿区测水组含煤段的沉积环境分析，提出该段为障壁岛──泻湖体系的沉积、垂向上表现为海退序列─—海进序列。聚煤作用受到沉积环境的重大影响。主要煤层含硫低与该区泻湖及表层海水淡化有关。图３，表１，参４。

| Abstract: | Sedimentological studies of coal-bearing member of Ceshui Fomation inLengshuijing coal mine indicate that it is sediments of depositional system of barrier is-land-lagoon and shows vertical sequence from regression to transgression,Coalaccumulation is influenced by depositional environments in a great degree. Low sulfur ofmain coal seams originates from the desalination of seawater in lagoon environments inthis area. 3figs.,1tab.,4refs. |
