摘要
From the analysis of sedimentary sequence of coal-bearing strata and sedimentary environment, the influencing factors of coal accumulation of Lower Jurassic Badaowan Formation in Junggar Basin are discussed. It is shown that the balance-standing time/period between the rate of accommodation changes and the rate of peat deposition is a major controlling factor to form a stable distribution of the coal seam. So the isochronous distribution of the coal seam can be as a sequence boundary. This paper presents the model for sequence stratigraphy of the Badaowan Formation, which could be as a guide for high-precision sequence stratigraphic correlation and lithologic reservoir exploration in this area.
