Heinrich events recorded in a loess–paleosol sequence from Hexigten, Inner Mongolia
We describe the last glaciation climatic history Marine Isotope Stage (MIS, 2–4) from 66.7 ka to 14.5 ka in Hexigten, northeast Inner Mongolia, North China. The climate of the region experienced frequent and significant fluctuations between dry-cold and less dry-cold during the late MIS4. The climat...
