| 摘 要： | 利用钻孔岩心数据,对青海北部木里煤田外力哈达矿区侏罗纪湖盆相陆源碎屑含煤岩系进行了层序地层学和聚煤作用的研究.研究区侏罗系共划分出5个三级层序及相应的体系域.在每个层序中,低位体系域由河道相或分流河道相灰白色粗砂岩、细砂岩组成,湖侵体系域由泛滥盆地相或分流间湾相砂质泥岩组成,高位体系域由湖泊相或分流间湾沼泽相泥岩和碳质...

| Abstract: | Sequence stratigraphy and coal accumulation of the Jurassic lacustrine clastic coal measures in the Wailihada mining area of northeastern Qinghai were studied using borehole data.A total of 5 third-order sequences and corresponding systems tracts were subdivided.Within each sequence,the lowstand systems tract(LST)is composed of grayish white coarse-grained sandstones of fluvial or distributary channel facies,the transgressive systems tract(TST)consists of sandy mudstones of flood basin and interdistributary... |
