DOI: 10.1002/esp.4779
Abstract: Permeability differences in multi‐cycle loess–paleosol aeolian sediments, which are still poorly understood, have the potential to significantly improve our understanding of climatic change during the glacial–interglacial periods of the Quaternary. In this study, the permeability… read more here.
