摘要
从砂岩体的微观特征及粘土岩的染色特征(如碎屑沉积岩、粘土岩等特征)切入,分析了童子岩组一段的岩性相、沉积组合以及相的空间配置。提出了滨海碎屑沉积体系、潮坪沉积体系、障壁岛—泻湖沉积体系和浅海沉积体系为天湖山煤矿区上姚井田主要含煤段P(1t1)的沉积环境,并探讨了其聚煤规律。
Proceeded with microscopic features of clastic sedimentary rocks and staining features of claystones, analyzed lithofacies, sedimentary association and facies configuration in space of No. 1 member of Tongziyan Formation. Put forward littoral clastic, tidal flat, barrier island - lagoon and neritle sedimentary systems were depositional environments of main coal-bearing member （P1t1） in Shangyao mine field, Tianhushan coalmine area. Then coal accumulating pattern was discussed.
