鲁西陆表海盆地富煤单元的形成与分布

FORMATION AND DISTRIBUTION OF COAL-RICH UNIT OF EPICONTINENTAL SEA BASIN IN WESTERN SHANDONG

讨论了鲁西煤田富煤单元的形成及分布同沉积体系类型、沉积环境演化的关系．运用现代综合沉积学、地层学的新理论──层序地层学分析方法，研究了含煤地层层序地层格架与富煤单元的成因联系．研究表明，海平面变化控制了沉积体系的类型和演化，而沉积体系控制着煤聚积以及富煤单元的形成和分布．

The relationship among the formation and distribution of coal-rich units , the types of depositional system and evolution of depositional environment of units were discussed using the modern methods of a new theory synthesized from sedimentology and stratigraphy──sequence stratigraphy,the authors studied the genetic relation between the sequence stratigraphical frame and the coal-rich units.It shows that change of sea level controlled the accumulation of coal and the formation and distribution of coal rich units.
