| 摘 要： | 海拉尔盆地为海西褶皱基底上发育的晚中生代—古近纪断-坳陷盆地,控盆的边界断裂主要为北东向和北北东向,形成于早白垩世,之后经受了多期反转。海拉尔盆地的沉积可划分为3大构造层:兴安岭群上段、铜钵庙组和南屯组为断陷构造层,大磨拐河组和伊敏组为断-坳转换构造层,上白垩统青元岗组和古近系为坳陷构造层。该盆地在古近纪发生萎缩并闭合,在近东西向的挤压力作用下形成北东向的反转构造带,为油气的聚集提供了良好的圈闭。新近纪开始新一阶段的拉张和沉陷。该地的新构造运动相当活跃,本文论述了其主要表现为断陷湖盆的形成、地表径流的分布和断阶构造的发育,指出其特征为继承性和加强性,使盆地发育阶段的坳(凹)陷在新近纪内进一步沉陷。在此基础上讨论了海拉尔盆地的油气勘探前景。

| Abstract: | The Hailar Basin, in northern part of the Inner Mongolia Autonomous Region and to the west side of the Da Hinggan mountains, was a Late Mesozoic-Paleogene basin, with the basement being Hercynides. The boundary faults to control the basin developing of NE- and NNE-strikings created in Early Cretaceous, and overprinted by later deformations. The sediments in the Hailar Basin could be divided into three main structural layers, in ascending order, the Upper Member of Hingganling Group, the Tongbomiao Formation and Nantun Formation making up the fault-depression layer, the Damoguaihe Formation and Yimin Formation making up the faulting-sinking transitional layer, and the Upper Cretaceous Qingyuangang Formation and the Paleogene being dawn-warping layer. The basin shrank and closed in Paleogene, and the NE-striking faults reversed and trapped the oil-gas by a nearly W-E compressive stress field. Another generation of rifting and extension occurred in Hailar area during Neogene, so that the neotectonics was relatively active in the area. The paper described the main neotectonic phenomena, such as the Pleistocene lacustrine basins, nowadays surface runoffs and the tilting structures, and point out the neotectonics being characterized with inheritance and enhancement, which resulted in the depressions of the Hailar Basin subsided further in Neogene. Based on the basin evolution, the potentials of oil-gas exploration in the Hailar Basin were discussed and the NE-striking structures might be main targets. |
