Characterization of Modern and Fossil Mineral Dust Transported to High Altitude in the Western Alps: Saharan Sources and Transport Patterns
Figure 6
87Sr/86Sr values as a function of the aerosol surface, the mica and chlorite contents, and the EF Pb for the Colle Gnifetti ice-core (CG, circles) and Jungfraujoch samples (JFJ, crosses). Pre-1910 CG samples are represented by empty squares, whereas post-1910 samples are represented by filled circles. Correlation coefficients are calculated over the entire dataset (CG record and JFJ samples), except for EF Pb (CG samples after 1910). The color-shaded areas correspond to the aerosol surface classes of Figure 3 (<30 and >100 mm2/kg).
