| Zusammenfassung |
| The development of a measurement system for tiny water quantities (submicroliters) enables
the precise determination of water contained in fluid inclusions of speleothems. The
comparison of the specific water content (water per g calcite) in selected stalagmites with
precipitation related proxies such as δ18O and Mg/Ca ratios from stalagmites and pollen
abundance in lake sediments revealed a correlation between precipitation and water content in
the according growth periods. Investigation of stalagmites from Central Europe (Bunker
Cave) and Southern Chile (Marcelo Arévalo Cave) confirm this relation, which is
independently constrained by modelled drip rates using a reverse stalagmite model. The
obtained data already enable a first interpretation of the speleothem water content records
with regard to paleoprecipitation. |
