综合物探方法在玄武岩覆盖区的应用——以三道砬子河—马鞍山剖面为例

Application of comprehensive geophysical method in basalt covered area:take Sandaolazihe-Ma'anshan section as an example

通过在长白山玄武岩覆盖区进行的重力、电法、磁法等物探技术手段,采取物探多方法、大深度、高精度、长剖面的工作方式,推断了覆盖层下基岩岩性、分布特征及断裂构造位置及产状。

mBy means of geophysical technology such as gravitational, electrical and magnetic methods in the Changbai Mountain basalt covered area, the method of geophysical exploration with multiple methods, deep depth, high accuracy and long section is adopted. The lithology and distribution characteristics of the bedrock, and the location and occurrence of the fault structure are deduced.
