摘要
小波变换是重力异常分解的有效工具,利用小波多尺度分析方法,可以将重力异常分解到不同尺度空间中。不同尺度的重力异常反映了不同地质体的规模和埋深。作为一种新的有效的位场分离途径,小波多尺度分析方法为重力资料解释和研究地壳结构提供了新的思路,在目前广泛开展的深部找矿工作中将发挥重要的作用。
Wavelet transformation is an important tool for decomposing the gravity anomaly. With it, gravity anomaly canbe transformed into different scale anomalies. And the gravity anomalies with different scales correspond to the differentore bodies with different scales and buries. As a new and effective means for potential field decomposition,the waveletmulti-scale analysis method provides a new way for gravity data interpretation and the earth＇ s crust study, and plays important roles in the current deep exploration.
