华北陆表海盆地海侵事件聚煤作用研究

Study on coal accumulation under marine transgression events in the epicontinental basin of North China

在研究了陆表海盆地聚煤作用特点的基础上 ,提出了海侵事件成煤作用观点 ,分析了其机理。海侵导致了陆表海盆地沼泽环境的形成 ,进而形成泥炭沼泽 ,而随后的海侵事件导致了先形成的泥炭迅速处于深水环境最终成煤。海侵事件成煤作用形成的重要层位如煤层、海相层均具有较好的等时性。

Based on the study of the characteristics of coal formation in epicontinental coal accunulation basin,the viewpoint that coal was formed under marine transgression is put forward by the authors and the mechanism thereof is also analyzed.Marine transgression resulted in the forming of swamp and then the peat swamp. And the transgression later on put the peat formed in advance in deep water environment to form coal in the end. The important stratigraphic horizons, such as coal seams, marine facies layers, formed with marine transgression are of the property of isochronism.
