英文摘要	[1] To determine the timing and spatial distribution of mid-Holocene drying over northern China, the mineralogical and oxygen isotopic composition of authigenic carbonate from a closed lake at Bayanchagan, southern Inner Mongolia, were measured. Further analysis and synthesis of the spatial geological data were performed. Results from Lake Bayanchagan show a significant drying at 6000 calendar years (cal years) B. P., indicated by dolomite precipitation and a striking rise in delta(18) O values. The synthesis of spatial data reveals a zonal distribution for timing of drying over northern China in the mid-Holocene, which began at 9000-7000 cal years B. P. in deserts of north-central China. At 7000-5500 cal years B. P., drying extended into the desert-steppe transitional zone and at similar to 4500 cal years B. P. into northeastern and south-central China. This pattern indicates that the east Asian summer monsoon has significantly retreated southeastward since the mid-Holocene, which may be related to orbitally induced Northern Hemisphere insolation changes. A retreat of similar to 400-550 km is inferred for the front of the summer monsoon from 6500 to 4500 cal years B. P.
