The Non-Residual Rb/Sr Ratio of the Huguangyan Maar Lake and Its Implications for Paleoclimate Change
详细信息   
摘要

Through comparative analysis of Rb/Sr ratios in non-residual, residual and bulk samples, the authors found that the Rb/Sr ratios in non-residual samples were the closest to the chemical weathering in the catchment basin.  During AD740~860 and AD1400~1750, the non-residual Rb/Sr ratios were much lower, indicating that the chemical weathering of the two periods were relatively strong. The results showed that chemical weathering in the catchment was dominantly controlled by precipitation, while the effect of temperature was not obvious.
