第二松花江西南岸西王家—哈达山一段,存在两种地层变动现象。规模较小的变动为第四系中的小断层和地裂缝,规模较大的变动为沿江岸边的滑坡。研究表明,第二松花江岸第四系中的断层、地裂缝等地层变动现象大部分与滑坡有关,属于非构造成因。根据第二松花江沿岸的地质特征,利用平原覆盖区的钻孔、地震反射等资料,结合地球物理探测结果,从地层、地貌、构造等方面分析第二松花江断裂的新活动性,认为研究区内第二松花江断裂第三纪以来是不活动的。 The second West Songhua River West West - Hadada a paragraph, there are two kinds of formation changes. Smaller changes are small faults and ground fissures in Quaternary, and the larger changes are landslides along the banks of the river. The study shows that most of the stratigraphic changes such as faults and ground fissures in the Quaternary of the second Songhuajiang River are related to landslides and belong to non-structural causes. According to the geological characteristics of the second coast of the Songhua River, the new activity of the second Songhua River fault is analyzed from the aspects of strata, geomorphology and tectonics based on the data of borehole coverings and seismic reflection in the plain coverage area and geophysical exploration results. The second Songhuajiang fault in the area is inactive since the Tertiary.
