This session forms a general platform for (paleo-)climate studies where stable isotopes are used as 'proxy' for environmental paramateres. The temperature dependency of isotopic fractionation with formation of phases such as carbonates, phosphates or other materials, is traditionally used for climate determination, although a number of studies have shown much wider application possibilities, ranging from variations of rainfall amount, moisture source, biogenic activity, volcanic deposition, to name a few. All kinds of presentations dealing with stable isotope analyses in (paleo)climate research are highly welcome.
