Sedimentary Features of the Bauxite-Bearing Rock Series in Central Guizhou
Keywords:Bauxite-Bearing Rock Series, Continental Deposition, Paleogeography Environment, Central Guizhou, Carboniferous.
Bauxite resources are abundant in Central Guizhou. Through systematically analyzing the sedimentary records of bauxite-bearing rock series, this paper reveals the paleogeography environment of this region, and explores the ore-control significance of favourable zone. The research shows that the ore-bearing rock series of bauxite in Central Guizhou is the continental deposition based on karst landform. Surrounding the paleo-land, the diluvial fan-diluvial uvala sedimentary system is developed in the eastern Xiuwen region and the diluvial fan-diluvial-control fan delta-diluvial-control lake sedimentary system is developed in the western Qingzhen region. Diluvial-fan channel sediments and diluvial-control-fan delta front sediments are the most favourable facies belt for bauxite occurrence. Moreover, serious dissolution areas in the diluvial uvala can also become the favourable aggregation sites for bauxite by rapid accumulation effect.
