摘　　要：利用基于小波多分辨技术的重力场参数相关系数对传统重力场数据进行再处理,并将该方法应用到某磷矿的重力勘探资料解释上,用求取空间各点的重力场参数的相关系数值来表征地下异常的分布情况。相关系数成像结果不仅印证了平面重力资料划定的磷矿矿脉范围,而且能划定更大范围的隐伏矿脉。利用该方法解释重力资料取得了良好的效果。This paper adopts the gravity field parameter and correlation coefficient based on wavelet multi-resolution technique to reprocess the traditional gravity field data,and applies this method to the interpretation of the gravity exploration data of a phosphate rock.The correlation coefficient values of the gravity field parameters at each point of the space are used to characterize the distribution of underground anomalies,which not only verifies the range of phosphate veins delineated by plane gravity materials,but also defines a wider range of buried veins.The application of this method into interpreting the the gravity data has achieved better effect.
