摘　　要：以潜山形成机制为原则 ,以潜山结构类型为基础 ,将济阳坳陷中生界潜山分为断块型潜山、块断型潜山、滑脱型潜山、褶皱型潜山、残丘型潜山。从潜山成因及圈闭组合特征出发 ,在区域上将济阳坳陷中生界潜山划分为 6个潜山构造带。认为潜山的分布主要取决于断陷盆地的结构单元特征及基底断裂的活动性质 ,济阳坳陷中生界潜山的形成和演化主要经历了三叠纪印支期褶皱隆升阶段、燕山期侏罗—白垩纪块断抬升阶段和第三纪喜山期拉张块断改造及覆盖掩埋阶段。Based on the formation mechanism and structure types of the buried hills, we can divide the buried hills in Mesozoic in Jiyang Depression into five types. They are fault-block type,block-fault type,surge type,drape type and monadnock type. According to the analysis on the cause of formation and the character of traps of the buried hills, the buried hills in Mesozoic in Jiyang Depression can be divided into six buried hill tectonic zones. It is thought that the distribution of the buried hills mainly lies in the structural features of rift basins and activity of basement fault. The formation and evolution process of the buried hills in Mesozoic in Jiyang Depression has experienced four periods: the Triassic draped and uplifted period, the Yanshan Jurassic-Cretaceous block-faulted and uplifted period, the Tertiary extended and block-faulted period and the buried period.
