摘要：

The strontium isotopic composition of 13 rainwater samples collected in November 1988 during a single rain event in the People's Republic of Congo range from 0.71326 to 0.71035 between the beginning and the end of the event. The isotopic variations are correlated with major and trace cation ratios. The coupled variation of isotopic and major elements ratios clearly implies the existence of at least two different aerosol sources. However, the lack of correlation between the Na/Sr, K/Sr and Sr-87/Sr-86 ratios indicates a more complex process than a simple binary mixing.
