AbstractAeolian dust deposits from continent and ocean have been extensively investigated to reflect past changes in source aridity and atmospheric circulations. Aeolian flux (AF) as a quantitative dust proxy has been widely used in both palaeoenvironmental reconstruction and numerical simulation. However, available AF data on the Chinese Loess Plateau (CLP) is too limited to assess the temporal-spatial variations at glacial-interglacial timescales, and therefore cannot be used as robust input parameters in palaeoclimate models. Here we investigate eight loess profiles along two N-S-aligned transects on the CLP to quantitatively estimate the AF variations over the last glacial-interglacial cycle. We first establish a refined chronological framework based on optically stimulated luminescence chronology and pedostratigraphic correlation. AF was then estimated by multiplying the sedimentation rate and bulk density. The results show that the AF increases from 2-18 g cm(-2) ka(-1) in the southeastern CLP to 14-105 g cm(-2) ka(-1) in the northwestern CLP. At glacial-interglacial scales, the AF varies from 2-20 g cm(-2) ka(-1) during the last interglacial to 8-105 g cm(-2) ka(-1) in the last glaciation. Due to more spatial coverage and better age constraints, our AF data can be used to refine other AF datasets and to improve the proxy-model comparison.
