| Zusammenfassung |
| We report an overview of Quaternary glaciers in Turkey, specifically on the southwest
Mediterranean coast. Small-glaciated mountains exist on the western sector of the Taurus
Mountain Range such as Akdağ (36.54oN, 29.57oE, 3016 m). Forty-one moraine boulders
from three glacial valleys on Akdağ were dated with cosmogenic 36Cl. Valleys on the north
side of the mountain were filled with few km long glaciers that terminated at elevations of
about 2000 m above sea level (a.s.l). The oldest glaciers reached their maximum positions
(2150 m a.s.l) by 35.1±2.5 ka ago (ka = 1000 calendar years). They readvanced during the
global LGM and reached their farthest locations (2050 m a.s.l) by around 21.7±1.2 ka ago.
Later, glaciers retreated and shortly stabilized during the Late Glacial at around
15.1±0.9 ka ago. Using the glacier modeling and paleoclimate proxies from the Eastern
Mediterranean, we estimated that if temperatures during the LGM were 8-11 oC colder
than modern, which is suggested by paleotemperature proxies from the region,
precipitation on Akdağ was up to two times more than that of today, in line with
comparable estimation on southwest Turkey. Same model suggests that the central Turkey
requires drier conditions, implying regional heterogeneity on LGM climates in Turkey. |
