The influence of near-surface winds on the Sr isotope composition of aeolian sediments: a wind tunnel experiment

► 87Sr/86Sr ratios varied with wind velocity and the amount of the fractions < 10 μm. ► Samples collected at the same site showed large variation in the 87Sr/86Sr ratio. ► The variations in 87Sr/86Sr ratios affect their use as clues to the dust sources.
