There are several competing hypotheses for the origin of loess in Europe but quantitative evidence is still rare. Here, Sr-Nd isotopic and bulk elemental composition of loess from Marine Isotope Stages 2 and 3 from three study regions in Central Europe -Nussloch (Germany), Grub (Austria) and Tokaj (Hungary) -are analyzed. This study aims at examining di erences and similarities of loess deposits throughout Europe, correlating loess with potential source rocks from major mountain ranges and comparing loess with oodplain sediments from main rivers as integrated samples of the drainage areas. The results show that European loess deposits are largely uniform and that sediment sources have been rather stable in the Southern and Eastern parts of Central Europe and more variable in West Central Europe. However, the methods used are not su cient to unequivocally con rm and reject potential sediment sources but, in combination, help to identify the most likely sediment origins. While a direct correlation of loess and potential source rocks is difcult, the comparison with oodplain sediments is most promising and con rms previous hypotheses. Loess from Tokaj and Grub is most likely a mix of material transported by the Danube River and sediments from the surrounding mountains. Rhine River sediments are probably the main source of loess at Nussloch.
