平果堆积型铝土矿成矿规律及赋存特征

Regularities of Mineralization and Abundanted-characteristics of Pingguo Stacking-type of Bauxite

广西平果铝土矿属岩溶堆积型铝土矿,其矿体的形成、规模、含矿率、矿石质量与沉积铝土矿层、岩溶洼地大小、矿源层的所处位置、地形地貌关系密切。文章对该矿床的成矿过程、控矿因素及富集特点进行了阐述,对矿床的赋存层位及含矿层的特征等方面进行了分析,为该类矿床的地质工作提供参考。

Pingguo bauxite belongs to karst stacking-type of bauxite, the formatiom, scale, mineral content and qulity of the ore deposite are closely related to the layer of sedimented-type of bauxite, the sizes of karst depres- sion,the locations of the deposite and topography. This article expounds the minerlization process, the factors of ore control and abundanted feature of this type of bauxite, and analyzes the locations of the abundanted layer and the characteristics of mineral-contented layer of the deposite and so on, which gives a reference to the Geological work on the same type of ore deposite.
