摘要
通过对个旧西区成矿地质条件和东区典型矿床地质特征的研究,综合地质、地球物理、地球化学和遥感等找矿信息,建立了个旧西区锡多金属矿综合信息找矿模型。根据找矿模型,优选出地层、构造、物探、化探、遥感等12个预测变量,在MORPAS平台上应用特征分析法对矿区进行了成矿预测,圈定了3个一级成矿远景区和3个二级成矿远景区。其中,个旧西区的梨花寨区(A2)和陡岩区(A3)成矿地质条件良好,具有很大的找矿潜力,为个旧西区新一轮的找矿工作提供了依据。
An integrated information exploring model is established to compare metallogenic conditions in the western Gejiu district with those of the eastern Gejiu district using the geological, geophysical, geochemical and remote sensing metallogenic information. According to this model, 12 prediction variables containing stratum, structure, geophysical, geochemical, remote sensing variables are chosen. Then characteristic analysis method was used to predict target areas in Gejiu district on MORPAS system. 3 first-order prediction target areas and 3 second-order areas were recognized in this study. The Lihuazhai （A2） and Douyan （A3） prediction target have largest mineralization potential in western Gejiu district, and are thus recommended for further exploration and prospecting.
