| 摘 要： | 桂西岩溶堆积型铝土矿赋存于岩溶洼地中的红土层中，具有矿床规模大、矿石质量优的特点。成矿物质来源于上二叠统底部的古风化壳型铝土矿层，成矿时代为早更新世，矿床成因与岩溶作用、红土化作用有关。成矿受矿源层、地层岩性、气候、构造、地貌等因素控制。

| Abstract: | The Karst-accumulation-type bauxite deposits in west Guangxi occur in the laterite crust develped in karst basins. The deposits have the characteristics of large scale of ore reserves and high quality of ore. The ore-forming materials come from the bauxite-bearing paleo-weathering crust. The metallogenic age is early Pleistocene. It is a bauxite deposit related genetically to karstification and laterization. The mineralization of the bauxite deposits is controlled by source-bed,lithology,climate,structure and geography. |
