Radiocarbon dating and the prehistoric archaeology of china Sms sexchat luxemburg
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools.The artifacts indicate that the cave was a Late Paleolithic foragers' camp.While there have been previous excavations of Late Pleistocene cave sites in the Yangzi Basin, the dating of these sites has been problematic.First, the complex deposition of interdigitating lenses of ashes, clays, and sometimes fine gravel requires systematic dating based on a series of radiocarbon determinations and this has been lacking.Secondly, accurate and precise radiocarbon dating of these sites in the past has proven to be difficult.
This results in a much clearer understanding of the chronology of Yuchanyan Cave and the age of the pottery found in this site, as compared to other Late Pleistocene caves in East Asia. The cave is 12–15 m wide along its east-west axis and about 6–8 m wide from north to south.
The Terminal Pleistocene warming was interrupted by the Younger Dryas ca. Although the Younger Dryas is seen in other regions as a generally cold and dry period, in South China the main effect of the Younger Dryas was probably the sudden onset of greater seasonality.
Understanding the local impact of the Younger Dryas on the basin of the Yangzi River and in particular in the limestone region south of the main river channel is still not possible (20).
The dates range from around 21,000 to 13,800 cal BP.
We show that the age of the ancient pottery ranges between 18,300 and 15,430 cal BP.
Numerous caves in the vast karstic landscape of the southern area of the Yangzi River basin of China are known to have been inhabited by hunter-gatherer groups during the Late Pleistocene and early Holocene.
