摘要
Based on geological and geochemical theories with respect to ore formation and halo formation,prospecting geochemical data in different scales,GIS information geochemical model of mineral resources is set up and the quantitative prediction is made.Anomly characteristics of typical ore field(ore deposit clustered area) and deposit are summarized and prospecting geochemical model of typical ore deposit in typical ore belt is set up so as to provide correlative evidence for geochemical and quantitative prediction of mineral resources of the predicted area.New factors of comparability,denudation degree,contrast value etc.are added during the prediction and confidence of optimization of prospecting targets is improved a lot.The correlation result and plane metal result are weighted averagely to give reasonable predicted mineral resources volume.Increment of copper mineral resources about 21 812.9 t is made for Caohezhang-Huanren area by the prediction.
