    • Abstract
  • Based on results of sequence stratigraphy and depositional system analysis,Jurassic system in Chaoshui basin is devided into two tectonic sequences,three first-order sequences,four second-order sequences and eight third-order sequences.It is showed that paleoclimate condition,tectonic movement and sedimentary emvironment are the main control factors of coal-enrichment zone contribution,and the units of coal-enrichment are located in fan delta depositional system and alluvial fan depositional system.
