摘要: Abstract The Rb/Sr ratio of lake sediments has been demonstrated to be a potential indicator chemical weathering by increasing work. However, Rb and Sr in are derived from both physical erosion. different forms may record environmental processes information. In this study, the variation patterns Daihai Lake were investigated. results show that display noticeably due their sources associated processes. Using ratios bulk reflect is not accurate. non-residual without detrital carbonates, representing leached catchment, can used as an index because minerals very sensitive climate change, content sediment determined more Sr2 + influx than physicochemical conditions water. correspondence between TIC/TOC also indicates good catchment.
