AMMA_SOP0 campaign													
Mineralogical concentrations (µg)													
Filter samples collected on Nuclepore membranes (0.4 µm, 47 mm)													
Columns provide with the mass of major minerals 													
<DL indicates that values were below detection limit													
A quantitative detection has not been performed for smectite. Symbols indicates samples for which smectite was detected (D) or not detected (ND)
