Description :
Variation in the rubidium to strontium (Rb/Sr) ratio of the loess-palaeosol sequences has been proposed to reflect the degree of pedogenesis and weathering in the northwestern region of China. To characterize the Rb/Sr ratio of the dissolved loads of a single catchment, the AA. analysed a 12.08 m sediment core from Daihai Lake in Inner Mongolia. Dating control was provided by Pb 210, Cs 137 and AMS C 14. The Rb/Sr ratios of the Holocene lake sediments are interpreted to be the direct results of changes in fluxes of dissolved materials controlled by climatic change within a single catchment.
