First discovery of the Laacher See Tephra in the Eastern Alps: Necessity for reassessing fallout patterns
Original language description
We report the pioneering identification of the Laacher See Tephra (LST) in the Eastern Alps, specifically in Lake Plansee, Tyrol, Austria. Using a comprehensive core-scanning workflow (magnetic susceptibility, computed tomography, XRF, μXRF, and electron probe microanalysis), we identified the LST despite the near-total dissolution of volcanic glass in alkaline lake sediments, by focusing on both the volcanic minerals associated with the eruption and the remaining geochemical signatures. This approach highlights the critical need to extend detection strategies beyond glass shards, particularly in cases of significant alteration and minute amounts of tephra glass shards.
