英文摘要	This study presents the results of a detailed paleoclimate investigation on stalagmite YL-1 (Yelini Cave, Turkiye). YL-1 grew between 117.13 (+0.57/-0.44) ka and 114.87 (+1.63/-2.89) ka within Greenland Stadial 26, indicating a positive moisture balance during the stadial conditions in this semi-arid region. Rainfall is significantly affected by sub-cloud and surface evaporation and decreasing net effective winter precipitation is recorded by high isotope values. Enriched delta 18O and delta 13C at 116.65 (+0.51/-0.39) ka are interpreted as a drought event that took place ca. 400 years before the end of the MIS 5e. This event, which was reported simultaneously in marine and terrestrial archives in the Northern Hemisphere, is a result of decreased cyclone activity linked to weakening of the Atlantic meridional overturning circulation. 87Sr/86Sr values of YL-1 are close to the host-rock values. Decreased 87Sr/86Sr ratio at 116.67 (+0.54/-0.38) ka reflects the intensified water-rock interaction due to lower precipitation. Along with prior calcite precipitation effect, this is also observed by increased Mg/Ca and Sr/Ca, while low P, Cu, Be, Y, and Zr concentrations indicate a lowered amount of soil-derived colloidal material. The MIS 5e/5d transition is marked by reduced insolation and enriched delta 18O at 116.24 (+0.53/-0.86) ka. The Greenland Interstadial 25 phase at 115.87 (+0.83/-1.71) ka is represented by more negative delta 18O and delta 13C.
