广西龙州—扶绥地区堆积型铝土矿床地质特征及勘查技术创新

Geological characteristics of accumulated bauxite deposit in Longzhou-Fusui area of Guangxi and innovation of exploration technology

龙州—扶绥地区柳桥—山圩和水口—金龙2处堆积型铝土矿大型矿床,其矿石自然类型为一水硬铝土矿,工业类型属高铁低硫铝土矿。在龙州—扶绥地区新发现了产于容县组与都安组平行不整合面上的铁铝层或铝土矿层。运用ENVI等多种方法提取多种遥感找矿信息,应用多元信息找矿技术圈定找矿远景区,并对地质取样方法进行了创新。

Two large-sized accumulated bauxite deposits are discovered in Liuqiao-Shanxu and Shuikou-Jin-long of Longzhou-Fusui area,and the ore natural type of both deposits is diaspore bauxite,and their indus-trial type is high-iron low-sulfur bauxite.Moreover,ferralite or bauxite ore beds which occur on accordant unconformity surface are newly discovered in Longzhou-Fusui area.The authors made use of various meth-ods including ENVI in extraction of multiple remote sensing prospecting information,and applied multi-in-formation prospecting technology in delineation of prospecting prospect area,and made innovations of geo-logical sampling methods.
