Abstract: The western of Guixi conducted its first comprehensive exploration of sedimentary bauxite deposits, carrying out ore prospecting prediction studies to provide more precise target areas for exploration. This article comprehensively reviews the latest exploration results of major sedimentary bauxite deposits in western Guangxi, conducts comparative studies on the characteristics of ore−bearing rock series, orebody geology, and ore quality of typical deposits in the area, explores the controlling effects of stratigraphic lithology, sedimentary paleogeography, paleogeomorphology, and tectonics on mineralization, extracts key information on mineralization, summarizes prospecting indicators, and carries out prospecting prediction research in combination with regional metallogenic geological conditions. Research indicates that sedimentary bauxite deposits in western Guangxi are primarily located within isolated carbonate platforms, with the surrounding reef limestone serving as the natural boundary for the ore bodies. The ore bodies occur within the aluminum−bearing rock series at the bottom of the Upper Permian Heshan Formation (P₃h) strata, which exhibit a typical “iron−aluminum−mud” rock (ore) assemblage. The central aluminum−bearing rock layer is the primary host for sedimentary bauxite deposits, and outcrops of this rock series serve as direct indicators for locating sedimentary bauxite deposits. Fold structures since the Late Paleozoic have reshaped the morphology of the ore bodies. Ore layers within anticlinal structures have been weathered and eroded, forming accumulated bauxite deposits, while those within synclinal structures have been preserved intact. Accumulated bauxite deposits are indirect indicators for locating sedimentary bauxite deposits. Synclinal structures surrounding high−quality accumulated bauxite deposits are favorable locations for exploring industrial ore bodies of sedimentary bauxite deposits.The Heshan Formation(P₃h) of the Upper Permian in the isolated carbonate platform facies area of the western Guangxi region contains an aluminum−bearing rock series, which is the main target layer for exploring sedimentary bauxite. Based on four prospecting prediction elements including the geological structure characteristics of the area and the previous engineering verification results, a total of 14 sedimentary bauxite prospecting targets have been delineated in the Napo−Pingguo and Fushui areas, including 6 Class A, 5 Class B and 3 Class C prospecting targets. This provides more precise prospecting targets for the exploration and investigation of sedimentary bauxite in this area.
