摘要：

In order to research the geological phenomenon of coal and oil shale paragenetic development in continental fault basin, sedimentology, tectonics, energy geology, sequence stratigraphy related theories and methods are used for studying coal and oil shale paragenetic development characteristics. The study found that five types of coal and oil shale association exist in continental fault basin; The development of coal seam and oil shale similarly need stable tectonic and fewer terrigenous detrital material supply, and organic matter composition both contain higher plants debris and algae in paragenetic coal seam and oil shale; The basin basement episodic tectonic activity mainly controls the sedimentary environment development and evolution of coal seam and oil shale; The climate conditions, terrigenous detrital material supply and organic matter supply are secondary control effect; In sequence stratigraphic framework, all kinds of coal and oil shale symbiosis combination could developed in lake expand system tracts, from early to late, from the lakeside to center, the thickness of coal seam gradually reduce, and the thickness of the oil shale gradually increase; In early high water system tracts, the large thickness and stable distribution of oil shale and coal paragenetic assemblage was mainly developed. Visible, the factors of basin basement episodic tectonic activity, sedimentary environment evolution, climate condition, terrigenous detrital material supply, organic matter supply factors collectively control the coal and oil shale paragenetic development characteristics in continental fault basin, and those paragenetic assemblage mainly appear in lake expand system tracts and early high water system tracts. © 2016, Editorial Department of Earth Science.
