Geochemical Dataset accompanying "Expanding the Tephrochronological Record in the Alps: Discovery of the Laacher See Tephra in Lake Plansee (Austria)"

This dataset contains all supporting data generated for the study:“Expanding the Tephrochronological Record in the Alps: Discovery of the Laacher See Tephra in Lake Plansee (Austria)”. The files include the raw and processed results used to establish the geochemical, chronological, and stratigraphic framework presented in the publication. Contents: 1. Age–depth models – two subfolders containing Bayesian age–depth modelling results for the sequences with and without tephra glass data. 2. XRF results – X-ray fluorescence (XRF) measurement results (raw data). 3. Magnetic susceptibility and spectroscopy results – full dataset of magnetic (MS) and spectral (Spec) measurements supporting the lithostratigraphic interpretations. 4. Micro-XRF raw data (unfiltered) – raw scanning output used for elemental mapping and peak analysis. 5. EPMA results – full electron probe micro-analysis (EPMA) output files of glass shard geochemistry. All data were collected and processed as part of the analytical work for this publication. Please refer to the main paper for methodological details and discussion.
