Early Holocene multi-centennial moisture change reconstructed from lithology, grain-size and chemical composition data in the eastern Mu Us desert and potential driving forces
The sequence of paleo-aeolian sands and sandy paleosols from the Shenmu section in the eastern Mu Us desert was used to reconstruct the history of moisture change during the early Holocene. Analyses of lithologies, grain size distributions and elemental compositions revealed that the early Holocene...

The sequence of paleo-aeolian sands and sandy paleosols from the Shenmu section in the eastern Mu Us desert was used to reconstruct the history of moisture change during the early Holocene. Analyses of lithologies, grain size distributions and elemental compositions revealed that the early Holocene climate in the eastern Mu Us desert experienced at least seven multi-centennial oscillations between humid and arid episodes. Four humid episodes occurred at 10,800 to 10,200 cal. (calendar) yr BP, 9800 to 9400 cal. yr BP, 8900 to 8300 cal. yr BP and 8000 to 7700 cal. yr BP. Three arid episodes occurred at 10,200 to 9800 cal. yr BP, 9400 to 8900 cal. yr BP, and 8300 to 8000 cal. yr BP.
