Holocene climate change in the eastern Mediterranean region: a comparison of stable isotope and pollen data from Lake G�lhisar, southwest Turkey

Using Leng and Marshall's (2004) expression of Kim and O'Neil's (1997) equation, the surface sediment 18O value of 6.2? (core top taken in 1999) and 18O water of 8.1? (average between 1997 and 2001, Table 2) suggests precipitation temperatures of around 23C, higher than the measured mean annual air temperature of 18C.

no mineralogical data are available, the range of oxygen isotope values is consistent with other calcite producing lakes in Ethiopia

Rainfall at Addis Ababa has a weighted mean 18O composition of 1.2?, while groundwater values recorded in Ethiopia range from a6.2? to a1.3? (table 2 in Lamb et al., 2000). It seems likely that the oxygen isotope values for the lake surface water (up to 9? VSMOW) result from evaporative enrichment (confirmed by the hydrological balance, Table 1), which is also represented in the high values for the carbonates in the surface sediments (18O 6.2? VPDB).
