| 摘 要： | 青海尕林格铁矿区由于地表有近200 m覆盖层,磁法勘探是直接而有效的方法.但是由于覆盖层厚,矿体埋深大,造成磁异常形态简单,难以进一步分析深部是否存在盲矿体.笔者在前人工作的基础上,运用小波多尺度方法分析了该区的平面磁异常,发现小波5阶细节(场源似深度600 m)为矿异常特征,推断了该区深度500 m以下可能存在磁铁矿...

| Abstract: | Although magnetic survey is a direct and efficient method for ore search,its effect is limited in the Galinge iron deposit of Qinghai Province.The reason is that thick cover and big depth of buried ore bodies characterize this deposit,thus the magnetic anomalies are of simple form that makes detection of deep concealed ore bodies difficult.Based on previous work,we used the wavelet multiple-scale method to analyze magnetic anomalies on the plane of this area.We discovered that five-order wavelet details are... |
