研究了济阳坳陷中、新生代构造体制转换时期的断裂组合特征,并对济阳坳陷构造体制转换与郯庐断裂带的关系进行了探讨。研究结果表明:济阳坳陷中、新生代盆地演化主要受控于欧亚构造域的板块拼接挤压以及滨太平洋构造域和郯庐断裂带的活动2种动力学背景,郯庐断裂在中生代末—新生代初由左旋到右旋的转变是济阳坳陷中、新生代构造体制转换的最直接的原因。
Studied the characteristics of fault assemblages during the Meso-Cenozoic tectonic regime transition in the Jiyang Depression, and discussed the relationship between tectonic regime transition and the Tan-Lu fault zone in the Jiyang depression. The results show that the evolution of Mesozoic and Cenozoic basins in Jiyang Depression are mainly controlled by the plate tectonic extrusion of the Eurasian tectonic domain and the two dynamic backgrounds of the activities of the Binhai Pacific and Tanlu Faults. The most direct reason for the transition from Mesozoic and Cenozoic tectonic regimes in the Jiyang Depression at the end of the Late Cenozoic to the dextral rotation at the beginning of Cenozoic.
