| 摘 要： | 恰功铁矿是近几年新发现的矿山,矿体的形态、大小、走向、位置、产状、边界等几何特征还没有清楚的认识。为了弄清这些问题，笔者通过小波多尺度分析理论模型数据和实测数据进行分解处理，对比了向上延拓和小波多尺度分析方法在磁测资料处理中的应用效果，证明了磁异常小波多尺度分解方法对矿山的深部找矿具有积极的作用。

| Abstract: | ：The Qiagong iron deposit is a newly discovered deposit, but geometric characteristics of its ore body such as the shape, size, strike, position, attitude and boundary have not been systematically studied. Based on a wavelet and multi scale analysis of theoretical model data and measured data and a comparison of the application results between the upward continuation and the wavelet and multi scale analysis, the authors hold that the wavelet multi scale decomposition of magnetic anomaly can play an important role in search for deep buried mineral deposits. |

| Keywords: | discrete wavelet transform upward continuation magnetic anomaly spectrum analysis 2.5 D inverse Qiagong iron deposit |
