| 摘 要： | 济阳盆地中生代构造主要包括：印支期ＮＷ向压性构造（褶皱及逆断层）、消亡的ＮＷ向负反转半地垒及半地堑、燕山期ＥＮＥ向压性构造（褶皱或逆断层）、ＳＮ向地垒。印支期ＮＷ向压性构造是华北板块同扬子板块的聚敛运动的产物，而ＮＷ向负反转地垒和地堑、ＥＮＥ向压性构造及ＳＮ向地垒导源于郯庐断裂的左旋剪切作用，新生代郯庐断裂右旋剪切运动导致上述构造消亡并成为隐伏构造。中生代隐伏构造为济阳盆地深层勘探提供了潜山圈闭（

| Abstract: | Mesozoic structures in the Jiyang basin mainly include Triassic NW - striking compressive structures (folds and reverse faults) , NW-striking negative inverted half - grabens and half -horsts, Jurassic-Cretaceous ENE - striking compressive structures (folds or thrust faults) and N-S-striking horsts. NW - striking compressive structures resulted from the convergence between the North China plate and the Yangtze plate during the Triassic, while all the others originated by the sinistral shear of the Cenozoic Tanlu (Tancheng-Lujiang) fault, an active continental strike-slip fault in East China. Mesozoic structures became inactive due to the variation of the strike slip of the Tanlu fault, i. e. , the Mesozoic structures were buried by the Cenozoic strata. Therefore, promising traps for petroleum exploration below 4000 m in depth are as follows- buried hill traps (NW -striking folds, overriding blocks and half horsts, ENE -striking folds or overriding blocks, N-S-striking horsts) , Paleogene drape anticline traps and lithologi-cal traps. |
