通过对明水-绥化地区构造及地层层序分析,使用构造变形时期、生长指数、断层活动速率以及构造演化史剖面确定断裂形成和活动时期,结合平衡剖面获得的构造几何形态明确明水-绥化地区断裂的形成演化过程及其特征。研究认为,明水-绥化地区断裂的形成演化经历了火石岭组-营城组时期的伸展变形,登娄库组-嫩江组时期主要发生整体拉张变形,形成了一系列沿着主干基底断层发育的断裂密集带,四方台组-古第三系时期主要发生反转构造变形,表现为部分主干基底断层发生反转构造变形。从明水-绥化地区的地震剖面和所做的典型地质剖面的构造演化史剖面中可以看出断裂在不同时期表现为不同的变形特征。深入研究明水-绥化地区的构造演化特征,将对油气勘探起一定指导作用。
Based on the tectonic and stratigraphic sequence analysis of the Mingshui-Suihua area, the tectonic deformation period, growth index, fault activity rate and tectonic evolutionary history are used to determine the fracture formation and active period. The structural geometry obtained from the balanced section is determined by the explicit water-Suihua Formation and evolution of regional faults and their characteristics. The study suggests that the evolution of the Mingshui-Suihua fault has undergone extensional deformation during the period of the Huoshiling Formation-Yingcheng Formation, and that the total delamination deformation has occurred during Denglouku Formation-Nenjiang Formation, forming a series of faults along the main basal faults In the Sifangta Formation-Palaeozoic period, the reverse tectonic deformation mainly occurs, which is characterized by the overturning of structural deformation of some main basal faults. From the profile of the Mingshui-Suihua area and the tectonic evolution history of the typical geological sections, it can be seen that the faults show different deformation features at different periods. In-depth study of the tectonic evolution characteristics of the Mingshui-Suihua region will play a guiding role in oil and gas exploration.
