Climatic change in northern Ethiopia during the past 17,000degreesyears: A diatom and stable isotope record from Lake Ashenge

isotopic values d18O of calcite precipitating in the surface waters of Zoi¿½ar Lake obtained from a buoy and anchor rope concretion growth show values (between ?2 to +1? vs V-PDB) coherent with calcite formation in isotopic equilibriumwith epilimnetic lake waters (+1 to + 6??18Owater (V-SMOW))

BM, ZK 04/01/2019: wrong longitude, should be W not E

XRD, SEM; calcite layer composed almost only by rhomboedric calcite crystals, 5?15 ?m long

However, the continuous enrichment of 18O, due to evaporation, during spring and summer results in heavier isotope values at the end of the warm seasons. Consequently, the isotopic oscillations can be interpreted as a reflection of changes in the intensity of the evaporation processes (Li and Ku,1997) that cancel out the opposite effect of the temperature increase (decreasing isotopic fractionation with increasing temperature; McCrea, 1950).
