摘要
分析了东北地区的重、磁场特征,同时对研究区的布格重力异常和航磁异常数据进行水平和垂直求导。水平和垂直参量图能给出断裂和走向的信息。结合布格重力异常图可以得出东北地区重力梯度带的走向和边界,并对比重力和磁力的垂直和各个角度的水平二阶导数来综合确定东北地区梯度带。利用求重力和磁力的水平和垂直二阶导数来划分东北地区梯度带。
Analyse the character of the gravitation and magnetic force of the Northeast China and at the same time vertically and horizontal differential coefficient of the gravitation and magnetic force can gave the faulted plate model and tend towards.So,we can gained the information of the Northeast China compare the map of the gravitation and magnetic force.Compare the map of the vertically and horizontal differential coefficient of the gravitation to find the synthesize result of the Northeast China.This disserta...
