| 摘 要： | 以光薄片观察、X射线衍射分析及电子探针等先进方法为手段,对靖西县三合铝土矿的硬水铝石和三水铝石的矿物特征进行研究,并探讨其成因机制。研究认为该地区在表生条件下,含铝母岩经红土化风化作用形成三水铝石,三水铝石经变质作用脱水形成硬水铝石。

| Abstract: | Taking optical thin section,X-ray diffraction and electronic probe as testing methods,the study has researched the mineral characters of the diaspore and gibbsite from the Sanhe bauxite deposit in Jingxi County with its ore-forming mechanism being discussed.The study has believed that the gibbsite in this area is formed as the aluminum-bearing parent rocks were weathered by lateritization under supergene conditions;while diaspore is formed as the gibbsite was metamorphosed and dehydration. |
