Last deglaciation was interrupted by an abrupt cold event known as the Younger Dryas (YD), following the Allerød warm period. This cooling event initiated by an unknown trigger was exacerbated by subsequent shifts in diverse climatic factors. A significant challenge in understanding the alteration in the climate system during this transition stems from the limited knowledge about how the dust source regions (i.e., the Asian deserts and the Sahara) changed in their relative contributions to Arctic dust from the Allerød to the YD. In this study, in order to constrain the provenance of dust in Greenland ice we examined high-resolution mineralogical and geochemical characteristics of individual insoluble particles retrieved from the Greenland Ice Core Project (GRIP) ice core samples, which cover the Allerød/YD transition. The analysis was performed by using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX). Our findings revealed relatively lower chemical index of alteration values and kaolinite-to-chlorite ratios during the late-Allerød period, indicating a predominant contribution from the Asian deserts. In contrast, the early phase of the YD showed the opposite trends, implying an increased contribution from the Sahara. These temporal changes in the relative contributions from the dust source areas were believed to be driven by variations in dust emission rates in the source regions and atmospheric circulation patterns that affected dust transport from the source areas to Greenland.
