| 摘 要： | 大同侏罗纪煤田内不存在边缘相带,也不存在湖泊相带,它不是一个完整的聚煤盆地,只是一个规模巨大的侏罗纪聚煤盆地的一个部分。大同煤田的大同组含煤岩系形成于这个大型盆地的中心地带与边缘地带之间的周期性地被湖水淹没的冲积平原地带。

| Abstract: | There is no periphery facies in Datong Jurassic Coalfield, and no lalee facies eituer. Datong coalfield is only a part of the vast Jttrassic coal-accumulating basin. Datong formation which bears coal-beds formed on the alluvial plain between centrial and fringing zones of the basin and P-eriodically covered with lake water |
