| 摘 要： | 松辽盆地位于西太平洋大陆边缘北部,其主体部分位于黑龙江板块群的中部.松辽盆地整个上部地壳所受到的挤压应力场在南北两大地区存在空间差别.在板块构造理论指导下,利用研究区内的地震长剖面资料,研究松辽盆地滨北地区区域构造特征.通过分析认为,滨北地区东、西部多为隆起或斜坡区,而中部多是凹陷,从南向北,地层沉积厚度逐渐变薄.早期的断层活动导致了凹陷内凹隆相间的构造特点.

| Abstract: | Songliao basin is located in north west of the Pacific continental margin, its main area lies in the middle of Heilongjiang plates. The compression stress field of the upper crust in Songliao basin is different from place to place especially from north to south of the area. With plate tectonics, the authors studied the regional tectonic characteristics of North Harbin in Songliao basin using the long seismic profiles. With seismic analytic interpretation the authors gained that there are uplifts and depressions in East and West of the area, and most of the depressions are in the middle part of the basin. From South to North the sedimentary thickness gradually becomes thin. The earlier fault movements resulted in the tectonic characteristics of the area with alternating uplifts and depressions. |
