摘要
在区域成矿特征与典型矿床研究的基础上,系统总结了广西堆积型铝土矿的成矿地质、地球化学和遥感特征,深入分析了堆积型铝土矿的成矿控制因素,建立了区域成矿模式。在此基础上,运用基于GIS的矿床模型综合地质信息预测方法对广西堆积型铝土矿进行了综合定位和定量预测,共圈定了102个最小预测区,估算未查明预测资源量3.03×108t。该成果对广西堆积型铝土矿进一步找矿工作具有重要的指导意义。
Based on existing study on regional metallogenic characteristics and typical deposits in Guangxi, we not only summaried systematically geology, geochemistry and remote sensing features of accumulative type bauxite mineralization in this area, but also deeply analyzed major ore-controlling factors. Thus, regional metallogenic model is set up. We＇ve got comprehensive localization and quantitative estimation of accumulative type bauxite in Guangxi by GIS-based deposit modelling comprehensive geological information prediction method. The conclusion is as follows： 102 minimum tracts are given out, and potential resources amount to about 303 million tons, which has highly indicative significance for further ore-prospecting of this type.
