摘　　要：在赣西蒙山岩体北缘某硅灰石矿普查区开展高精度重力勘探,利用小波分析方法对重力异常分解,并分析重力异常的细节和逼近特征及其地质成因,利用径向功率谱计算其场源埋深,推断可能的成矿有利部位。经钻探工程验证,见矿效果良好,表明小波多尺度分析在重力数据资料处理中具有较大的应用研究价值。High precision gravity exploration is carried out in the survey area at a wollastonite deposit in the northern margin of Mengshan rock mass in Jiangxi Province,and the wavelet analysis method is used to decompose gravity anomaly,and the details and approximation characteristics of gravity anomaly and its geological genesis are analyzed,and the field source burial depth is calculated by radial power spectrum.The possible favorable parts of mineralization are inferred for,and drilling verification work is also carried out.The verification result shows that the multi-scale analysis of wavelets has the great application research value in gravity data processing.
