Coal occurrence characteristics of Paleogene coal measure strata and coal accumulation discipline in Shandong Province

In order to rveal the characteristics of Paleogene coal measure strata and the coal accumulation discipline in Shandong Province,the paper used the seque nce stratigraphy and the coalfield geology as the guide in combination with the structural geology and sedimentolo-gy related theory,the coal-accumulation discipline and C haracteristics of Paleogene coal measure strata was discussed. It turns out conclu-sion:Wutu group Ljiaya formation is the paleogene coal measure strata in Shandong Pr ovince,which hosts in the Cenozoic fault basin con-trolled by the fracture,coal and oil shale interbedding sedimentary formation, syndepositional structure contral the coal m easure strata's sed-imentation,the sediment flling and evolution of the basin are mainly controlled by the boundary faults activities. Huangxian coal accumula-tion and fault basin is the continental facies fan dalta and lake sedimentation,the coal measures can be divided into fan delta, braided riverdelta,near shore-lacustrine marsh sedimentary system,coal accumulation is the most intense in braided river delta system,the coal accu-mulation is controlled by the basin flling and the variation of basin water mechani sm and when the boundary faults activities is stable,ter-rain differences is lttle,lakeside zone of basin water in the period of expansion,the coal accumulation mostly take pl ace.
