尕林格第四纪堆积物盖层厚度达150 m~220 m,属第四纪砂砾层下伏基岩及矿体。该区主要运用磁法勘探方法,该方法中的小波多尺度分解经过多阶细节分解能把不同深度的磁异常特征划分开来,并能确定底部的磁异常边界。再结合地质体特征运用二度半人机交互正反演能发现剩余磁异常,利用剩余磁异常推测深部隐伏矿体的位置及倾向,可以指导深部地质找矿。

The thickness of Galinge guaternary deposits cover layer is 150-220 meters,rock and ore body quaternary is under the gravel layer.The magnetic exploration is mainly used in this area.Multiscale wavelet decomposition after order detail can make different depth of themagnetic anomaly characteristics to separate,and determine the boundary at the bottom of the magnetic anomaly.The residual magnetic anomaly with geological features can be found using the two degree half interactive in-version.The location and orientation with the residual magnetic anomaly that deep concealed ore body were used as a guide fro the deep geological prospecting.
