On the basis of previous studies, characteristics of provenance of bauxite in Guizhou were comprehensive analyzed, and draws the following conclusions: 1) All he Cambrian, Ordovician, Silurian, Devonian and Carboniferous have provided ore-forming materials for the formation of bauxite, but for different metallogenic regions, the main provenances are not the same; 2) Different parent rocks can provide ore-forming materials for bauxite formation in different stages, the same mother rock can also provide ore-forming materials for the same bauxite in different stages; 3) The sea level changes of South China Sea and Yangtze Sea have controled the formation of bauxite in Guizhou.
