From: Spatial and temporal variations of Rb/Sr ratios of the bulk surface sediments in Lake Qinghai

Figure 2

Plots of Rb/Sr ratios vs. Sr contents. The mean Rb/Sr ratio of the surface sediment in Lake Qinghai is less than 0.15. The mean Rb/Sr ratios of loess in Lake Qinghai catchment and of the river sediments are 0.33 and 0.62, respectively, which are similar to the Rb/Sr ratio of upper continental crust (UCC, 0.32) and that of the shale (0.80). Sr contents and the Rb/Sr ratios of upper continental crust (UCC) and shale are from reference [4].
