Description :
Because of the different geochemical behaviour of rubidium and strontium in earth surface processes, variations of the Rb/Sr ratios in lake sediments were used as a geochemical proxy of chemical weathering and past climate in a single watershed. In this paper the AA. provide data of decadal-scale chemical weathering since the Little Ice Age (LIA) by analysing the distribution of the Rb/Sr ratio in the Daihai lake sediments in combination with magnetic susceptibility, CaCO3, and clay mineralogy.
