| 摘 要： | 依据缓坡带对层序类型、地层结构特征的控制及地貌特征、成因将济阳坳陷缓坡带分为单断-沉积坡折型、单断-斜坡型和双断-构造坡折型三种类型.三种缓坡类型构造-沉积演化背景不同,形成了不同的层序格架特征.济阳断陷盆地的构造演化史决定了较完整的缓坡带层序演化由双断-构造坡折型向单断-沉积坡折型再向单断-斜坡型演化.

| Abstract: | Based on ramp belt control the sequence type and the features of strata structure along with its physiognomy feature and the cause of formation, Jiyang depression ramp can be classified into three types of single fault-sedimentary, double fault-structural slope break type and single fault-clinoform type. As a result of the different structural-sedimentary evolvement background, there formed distinct features of sequence framework. The structural evolvement history of Jiyang depression results in comparatively whole sequence evolvement of gentle slope belt, that is transition from double fault-structural to single fault-sedimentary slope break type, and then to single fault-clinoform type. |
