| 摘 要： | 依兰盆地为伸展作用下形成的半地堑式断陷盆地,油页岩发育于古近系达连河组中。油页岩与煤层伴生,分布在煤层顶部,是最主要的含矿层位。它形成于湖泊体系与沼泽体系,主要发育在水进体系域与高水位体系域中。其中,高水位体系域即上煤层顶板存在油页岩密集段,使得盆地油页岩资源潜力大幅度提高。达连河矿区是油页岩富集成矿的中心区带,东西向断裂控制着达连河组油页岩矿层的埋深以及展布成矿过程。

| Abstract: | The Yilan Basin belongs to a half graben faulted basin of extension of regime.The oil shales are found in the Palaeogene Dalianhe Formation.The Dalianhe Formation is the main mining horizon where the oil shales lie on the top of coal beds.The oil shales form in the system of lake and wetland,mainly in transgressive system tract and highest system tract.The richest horizon of oil shale has been found in the highest system tract which increases the potential of oil shale in the Yilan Basin.A fault trending east-west controls the buried depth,distribution and ore-forming process of the oil shale. |
