- Abstract
There are three types of bauxite deposits in Guangxi: sedimentary-diaspora, accumulation-diaspora, and accumulation-gibbsite. Considerable amounts of bauxite of various types are medium- to large-scale and the best ore quality is from the accumulation-diaspora type. The bauxite ore concentration areas in Guangxi are mainly distributed in western and central Guangxi, followed by southwestern Guangxi. Among them, most high-quality diaspora type bauxite deposits are distributed in two ore concentration areas: Napo–Jingxi–Debao and Pingguo–Tiandong–Tianyang. The accumulation-gibbsite type deposits are mainly distributed in the ore concentration area of central Guangxi, while some are found in the Fusui–Longzhou ore concentration area in southwestern Guangxi. In Guangxi, sedimentary-diaspora type deposits are controlled by the coal strata of the Heshan Formation, Upper Permian, and were formed by later weathering products. Accumulation-gibbsite type deposits formed mainly from Quaternary laterite weathering of the carbonate distribution area. There are two combinations of bauxite deposit series in Guangxi, separately related to sedimentation and weathering. Based on a unified national metallogenic prediction method, we forecasted the bauxite resource potential of Guangxi and delineated seven bauxite metallogenic prospecting areas. The next prospecting will focus on sedimentary-diaspora type deposits.
