Climatic changes and their influences for the archaeological events during the holocene in central turkey and northern Syria

The project is a multidisciplinary geologic research program collaborated with archaeological excavations made clear the history of the climatic changes in Central Turkey and Northern Syria. The warming and very dry climate could be observed in the data from all our drillings in the early Holocene. The humid climate recovered at first in the northern part of Syria at 8500 years BE in the drillings from Lake Khatouniyeh. After 2000 years, the Holocene humidity started at the northern part of the central Turkey, at Lake Seyfe and Kultepe, Kayseri. However a dry climate continued in the southern part of the central Turkey such as Konya basin and the area of Lake Tuz. The above-noted recovery of humidity and its regional variability in the Holocene presumably was one of the major causes for the archaeological events, especially with regard to water availability.
