本文基于三维地质环境，综合白象山矿区积累的地质资料和物探成果，首先开展三维地质建模工作，详细刻画了白象山矿区的三维地质结构；在三维地质模型基础上，利用三维空间分析手段对三维控矿因素进行定量挖掘，提取了多种三维控矿因素；最后采用人工神经网络方法进行三维成矿定位预测。预测结果显示，人工神经网络三维成矿定位预测能很好的定位出已知矿体，同时显示，在已知矿体北部及东部的深边部具有较高的成矿概率，可作为开展进一步找矿勘探的靶区。因此，人工神经网络三维成矿定位预测对于白象山矿区的应用是有效的，可服务于新老矿区的深边部三维成矿定位预测，同时可为隐伏矿、盲矿的成矿预测和优选靶区提供定量、定位新的方法和途径。

This study integrates geological and geophysical data for the Baixiangshan iron deposit within the Ningwu Basin of the Middle and Lower Yangtze Metallogenic Belt,China,creates a three-dimensional geological model that can describes three-dimensional geological structure of Baixiangshan mining area in detail.Based on three-dimensional geological models,several quantitative exploration criteria have been extracted by using 3D spatial analysis,which were then used for the prospectivity mapping by using Artificial Neural Networks.The result shows that the prospectivity map can identifies the known orebody very well and highlights some high prospectivity areas in the north and east of known orebody that are favorable for exploration in the Baixiangshan mining area;these areas should be considered as high priority targets for future exploration. In addition, the result shows that 3D localization and quantitative prospectivity mapping by using Artificial Neural Networks is effective for the Baixiangshan Mining area.It can be used for the future mineral exploration in deep and peripheral areas of the new and old mining area and also provide a new localization and quantitative method for predicting the concealed mineralization and optimizing the prospecting target.
