Abstract
We analyzed mineralogical characteristics, and major as well as rare earth element concentrations from a cryptotephra layer in sediments of the infilled maar of Auel (Eifel, Germany). The results of detailed geochemical analyses of clinopyroxenes and their glassy rim of the specific layer are most similar to those from the Campanian Ignimbrite (CI) Tephra occurrence in a loess section at Urluia (Romania). Both records show idiomorphic green clinopyroxenes and formation of twisted minerals up to millimeter scale. The cryptotephra in the Auel core has an age of around 39,940 yr b2k in the ELSA-20 chronology, almost identical to the latest Ar/Ar dates for the Campanian Ignimbrite/Y5 eruption. These observations suggest that parts of the CI ash cloud were transported also northwestward into Central Europe, whereas the main branch of the CI ash plume was transported from southern Italy towards the NE, E and SE.
