Bauxite deposits located in the Wuchuan-Zheng’an-Daozhen, northern Guizhou Province, are important bauxite resources of bauxite belt belonging to paleo-weathering crust sedimentary deposits. Bauxites occur in argillite and shale of Lower-Middle Silurian Hanjiadian Group (S1-2hj), or on the limestone erosion surface of Upper Carboniferous Huanglong Formation. Ore controlling strata are Middle Permian Liangshan Formation. Geochemistry of immobile elements and correlation coefficients show that Al, Ti, Zr, Nb, Cr, Ga, Hf, Ta, Th and V were immobile during the bauxutization process.
