| 摘 要： | 本对华北地台的山西太原西山上石炭统太原组的7、8和11号煤层及其顶板灰岩的地球化学特征、煤核和生物化石进行了系统分析，发现煤层形成过程中有海水的影响，煤层上覆石灰岩形成过程中亦有淡水参与，说明煤层及其顶板灰岩在相序上是连续的，其海侵模式并不是突发型海便。而为渐进型海侵。本还应用层序地层学原理论述了海平面变化与聚煤作用的关系。

| Abstract: | The geochemistry,coal ball and fossils of the No.7,No.8,and No.11 coal seams and their overlying limestones of the Taiyuan Formation in the western Taiyuan Mountains of Shanxi Province have been systematically analysed.The results show that the coal deposition was associated with the marine transgression and the deposition of the overlying limestone was influenced by the influx of fresh water.It is believed that there is no facies break between the coal seam and its overlying limestone and the transgression across the boundary of these two lithological units was gradual rather than abrupt.The relationships between sea level changes and coal accumulation is further discussed based on the sequence stratigraphic principle. |
