Chemical weathering since the Little Ice Age recorded in lake sediments: a high‐resolution proxy of past climate
Abstract 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. Low magnetic susceptibility, low CaCO 3 , low...

The concordant change in both Sr and CaCO 3 concentrations with δ 18 O values in the Dunde ice core suggests that weak chemical weathering during the wet LIA was controlled by air temperature.
