| 摘 要： | 万全煤田为一中生代聚煤盆地,含煤岩系为白垩系下统青石砬子组。本文通过对煤系地层的沉积特征、沉积环境和相的分析,探讨了盆地的沉积演化历史,沉积环境演变与聚煤作用的关系;并指出本区主要煤层形成于扇前和扇间冲积谷地,扇前和扇间浅水湖盆中。

| Abstract: | The Wanquan coalfield is a Mesozoic coal-accumulational basin in which the coal-bearing strata are the Qingshilazi formation, Lower Cretaceous period. This paper deals with the sedimentary evolution and its relation with the coal-accumulation within the basin based on the analysis of the sedimentary features, environment and lithologie facies of the coal-measures. It presented that the main workable coal seams in the coalfield were formed in the interfan and fan-front shallow lake basin and alluvial belt. |
