Since Caledonian movement, the earth's crust in Henan area has been uplifted for so long time that the denudation of CambrianOrdovician strata has lasted for 140 Ma, which has provided preferable environmental conditions for the formation of bauxite. The material sources of bauxite were derived from both carbonate rock basement and silicate basement. Some changes of active elements might have taken place during the weathering, immigration and sedimentation, whereas for the stable elements certain connections did exist before weathering and after sedimentation and mineralization, especially for the ratios of the stable element couples. On the basis of a study and stimulation of the oxidation couple ratios between carbonate rock basement, silicate basement, aluminumbearing rock series and bauxite deposits, the material sources of bauxite can be judged. This is a quick and convenient mathematic statistic method for judging the material sources of the bauxite.
