广西红土型高铁三水铝土矿资源潜力预测

摘要

在对区域成矿特征与典型矿床研究的基础上,系统总结了广西红土型高铁三水铝土矿的成矿地质特征,深入分析了红土型高铁三水铝土矿成矿的控制因素.进而运用基于GIS的“矿床模型综合地质信息预测方法”对广西红土型高铁三水铝土矿进行了综合定位和定量预测,共圈定了42个最小预测区,估算未查明预测资源量7.67×108t.该成果对广西红土型高铁三水铝土矿进一步勘查开发具有重要的指导意义.%According to characteristics of regional mineralization and typical ore deposits in Guangxi, the authors made a systematic summarization of features of lateritic high-iron gibbsite bauxite mineralization and a thorough analysis of the factors controlling this type of bauxite deposits. Comprehensive localization and quantitative prognosis of lateritic high-iron gibbsite bauxite deposits were carried out by using the GIS-based deposit model comprehensive geological information prediction method. 42 ore targets were delineated, and potential resources are estimated to be about 767 million tons. These results have important guiding significance for further prospecting and development of the lateritic high-iron gibbsite bauxite deposits.
