【论文摘要】
<正>[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 inδ~(18)O values.The synthesis of spati...
