Abstract：The Luohe-Xiaobaozhuang iron ore district is located in Lujiang County, Anhui Province. The newly discovered Xiaobaozhuang ore deposit is buried at the depth of 1 350~1 800 m, 800~1 000 m under the Luohe main orebody. Before drilling engineering, it is necessary to separate Luohe magnetic anomaly in the upper part and Xiaobaozhuang magnetic anomaly in the lower part. Through the wavelet multi-scale transform, Xiaobaozhuang magnetic anomaly at the depth was separated and extracted perfectly. The large-size orebody predicted by six-step detailed anomaly was used to guide drilling exploration. The wavelet multi-scale transform can decompose gravity and magnetic anomalies in space at different scales and can effectively separate vertical superposition gravity-magnetic anomalies. The results achieved by the authors can be applied to exploration of the same type of iron deposits.
