Jining iron ore in the Shandong province is the richest iron deposit areas in China. The iron ores discovered so far have been estimated to be more than 5 billion tons, although most deposits contain some iron ore bodies up to 1000m in depth. Jining iron deposits are primarily of Superior-type (Ni and Ma et al., 2010).The thickness of Iron ore strata drilled in Tuntou village is 85.53 m. The depth for iron ore is in the range of 1612.89–1796.54 m. The corresponding analysis (CA) on profile of gravity and magnetic anomalies is a method that can be used to indicate that the moving-window application of Possion’s theorem allows rapid estimation of source magnetizationto-density ratios (MDR) from multisource data sets (Chandler et al., 1981). The intercept of CA in interpretations of regional gravity and magnetic anomalies should only be the contribution of remanence anomalies,which can be obtained by total anomalies subtracting induced magnetism background and gravity anomalies related parts (Zeng et al., 2006).Jining magnetic anomaly was cause of magnetite-bearing quartzite with strong remanent magnetization .Through an analysis of the intercept of CA , combined with the drilling data in this area, it is show that CA is an efficient method to delineate prospect areas for Jining iron ore .
