| 摘 要： | 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

| Abstract: | Along the southwest bank of the Second Songhuajiang river, from Xiwangjia to Hadashan, there are two patterns of stratigraphic variation. One is the faults and fractures of small scales of Quaternary. Another is the landslides of larger scales along the bank of the river. Detailed studies show that those stratigraphic alteration, faults and geofractures of Quaternary are not tectonism-genetic. They are mostly related to landslides. On the basis of analysing the geological characteristics, making use of the drilling, seismic reflection data and geophysical exploration results, it is suggested that the Second Songhuajiang fault had been inactive since Tertiary. |
