摘　　要：文章对罗河-小包庄西侧、南侧重磁低缓异常进行研究,预测了深部存在铁矿体,并通过钻探证实,取得了找矿重大突破;推测其向东、北存有较大延伸,预测资源量有较大幅度增加。小波多尺度变换将重磁异常分解到不同尺度空间,可有效分离具垂向叠加重磁异常。The gravity-magnetic lower anomaly in the west and south area of Luohe-Xiaobaozhuang ore district is studied and the existence of ore body in the deep is predicted .T he predicted ore body is con-firmed by drilling exploration .The gravity-magnetic anomaly indicates that the ore body has large ex-tension eastward and northward and the ore body should be a large-sized one .The wavelet multi-scalely transform can decompose of gravity-magnetic anomalies to space in different scales ,w hich can effectively separate vertical superposition of gravity-magnetic anomalies .
