摘　　要：利用宁芜地区(江苏部分)地质资料,结合磁场特征,重点对该区侵入岩体、断裂等地质构造进行了推断,编制了1:5万磁法推断地质构造图,为铁矿预测提供了地质构造等综合信息要素。采用RGIS2008软件2.5D人机交互拟合方法,累计估算铁磁性矿体资源量84642.6万t并分级。通过已知矿床的分布特征分析,结合磁测资料解释应用的成果,对宁芜地区(江苏部分)铁矿资源潜力进行了探讨和预测。Based on the geological data of Ningwu area（the Jiangsu part） and the characteristics of the magnetic field,the authors concluded the geologic structures including intrusive bodies,faults and so on in the study area,mapped a 1：50,000 tectonic map that was concluded by the magnetic method to provide the geologic structure and other comprehensive information for the iron resource prognosis.By using the method of 2.5D human-computer interaction fitting in software RGIS 2008,the authors estimated and graded the amount of 846,426,000 tons of ferromagnetic ore body.Through analysis of the known deposits distribution features,combined with the results of application of magnetic data interpretation,the authors carried out the discussion and the prognosis on the iron resources potential in Ningwu area（Jiangsu part）.
