Isolution 1.0: An Isotope Evolution Model Describing The Stable Oxygen (Δ18O) And Carbon (Δ13C) Isotope Values Of Speleothems, Michael Deininger, Denis Scholz

International Journal of Speleology

Stable oxygen and carbon isotope ratios (δ¹³C and δ¹⁸O) are the most applied climate and environmental proxies in speleothems allowing to infer past changes in cave drip water δ¹³C and δ¹⁸O related to climate and environmental variations from above the cave. However, disequilibrium isotope fractionation processes can modify δ¹³C and δ¹⁸O values in speleothems, which is in most cases difficult to estimate due to inter-dependencies on various cave specific parameter. To better understand the effect of these disequilibrium isotope fractionation processes proxy system models were developed in recent …
