| 摘 要： | 由牡丹江断裂、敦-密断裂、依-舒断裂和大和镇断裂所控制的中新生代盆地群是东北地区重要的合煤、含油气盆地。该盆地群的中新生代成盆过程以脆性伸展为主，发育断陷或裂陷层序，而坳陷层序(热沉降层序)不发育。古构造发育史、盆地沉降史和伸展史研究表明，研究区盆地群普遍经历了早期快速沉降(断陷期)-盆地衰减、抬升剥蚀-后期快速沉降-稳定衰减(或抬升剥蚀)。区内的成盆与构造演化过程分为涉及全区的中生代陆缘断陷期(J3-K1)、第一构造反转期(K2-E1)、新生代陆内裂陷期(E2-E3)和第二构造反转期(N)4个阶段，反映了两大盆地构造演化旋回。构造演化特征一方面为油气的多期成藏提供了盆地动力学条件，另一方面改造或破坏动、静态地质要素的时空分布及其匹配关系。

| Abstract: | Meso-Cenozoic basins controlled by Mudanjiang fault, Dun-Mi fau lt , Yi-Shu fault and Dahezhen fault are important basins of coal and oil-gas beari ng, NE China. Brittle-extension was the main process of forming basin group duri ng Meso-Cenozoic, so faulting or taphrogenesis sequences were well developed and depression (thermal subsidence) sequence was undeveloped in the basins. The stu dy of structural development, subsidence and extension process histories shows t hat the basin group universally went through early rapid subsidence (fault depre ssion) -basin attenuation and uplift denude-later intensive taphrogenes-sdeady attenuation or uplift denude. The process of forming basins and tectonic evoluti on can be divided into the four stages as Mesozoic epicontinental fault-depressi on all over the region (from later Jurassic to early Cretaceous), the first tect onic inversion(from later Cretaceous to Paleocene epoch),Cenozoic intracontinent al taphrogeny (from Eocene epoch to Oligocene epoch),the second tectonic inversi on(Neogene).The four stages reflect two main tectonic evolution cycles of the ba sin development. The tectonic evolution features of the basins resulted in dynam ic conditions for the multistage of hydrocarbon accumulation, on the other hand, transformed or destroyed the space-time distribution of dynamic and static stag e geological elements and their match relations. |
