郯庐断裂系的北延 (东北部分 )的性质及形成机制是东北东部重大基础地质和应用地质研究的重点课题之一。通过对其地质 -地球物理特征的综合研究 ,我们认为 :以抚顺—密山断裂带、伊通—依兰断裂带为骨干 ,长春—哈尔滨 (四平—德惠 )断裂带、东吴—昌图断裂带、新民—康平、洮安—阿荣旗断裂为主要成员的东北东部平移断裂系 ,均可包括在郯庐断裂系北延的“大家庭”中。从晚三叠始 ,随着中生代走滑—拉分张裂型火山沉积盆地的“开合”运动 ,东北东部的平移断裂系历经了 3个构造阶段、 8个地史时期的平移活动 ,并与斜冲运动发生多次更叠。其成因机制受控于泛太平洋板块相对欧亚板块的运动方式和速率的变更。
The nature and formation mechanism of the north extension (northeastern part) of the Tan-Lu fault system is one of the key topics in the study of major basic geology and applied geology in the northeastern Northeast. Based on the comprehensive study of its geo-geophysical characteristics, we believe that the Fushun-Mishan fault zone, the Yitong-Yilan fault zone, the Changchun-Harbin (Siping-Dehui) fault zone, Fault belts, Xinmin - Kangping, Ju’an - Arongtai faults are the main members of the northeastern part of the northeastern movement, may be included in the northern extension of the Tan-Lu fault system “big family.” Starting from the Late Triassic, with the “opening and closing” movement of the Mesozoic strike-slip split-type volcanic sedimentary basin, the transgressive faulting in the northeastern part of China experienced three translational stages and three translational activities during the geo-history and Occasionally more overlap with the ramp movement. Its formation mechanism is controlled by the change of the movement pattern and rate of the Pan-Pacific plate relative to the Eurasian plate.
