Climate change during and after the LGM in Central Turkey

Dogan from Ankara University published a new paper in the Journal of Quaternary International about the fluvial responses of Kizilirmak terraces to Late Quaternary climatic changes. A numerical chronology was established by AMS dating of fluvial sediments and Ar–Ar dating of a basalt sample capping the youngest terrace (Late Pleistocene terrace), indicating that the main incision phase was completed at the end of the LGM (Last Glacial Maximum, ~21,000 years ago). It appears that the major climatic transition from the LGM to the Late Glacial gave rise to aggradation in the fluvial system, and this event seems to be consistent with the timing of the regression phase of pluvial lakes and the termination of paleoglacier advances in the high mountains of Anatolia. doi:10.1016/j.quaint.2009.08.004
