摘要
Bsaed on informations of geology and geography, the Paleogene sequences including 1 first order sequence, 4 second-order sequences and 14 third-order sequences are recognized in the Bohai area. According to fracture shape, contact relations and section style of strata, 5 sequence stratigraphy and sedimentary system composition models are setted up including steep-slope zone, gentle structural slope zone, gentle slope zone, uplift and depression.
