2-2-2-2-2-2-2-2-2-2-2-2-2 From: "Adriano HG. Pimentel" <Adriano.HG.Pimentel@xxxxxxxxxxxxx> Dear all, Abstract submission is open for the IAVCEI 2025 Scientific Assembly, which will be held in Geneva (Switzerland) from June 29 to July 4, 2025. We invite submissions to our session on â??Applications, advances and challenges in tephrostratigraphyâ??. The deadline for abstract submission is December 20, 2024. Abstract submission form is available at https://on-line-form.eu/iavcei2025sa/abstracts/ <https://urldefense.com/v3/__https://on-line-form.eu/iavcei2025sa/abstracts/__;!!IKRxdwAv5BmarQ!bEL1SsyRDxn96Q6yfZkEm2i6NNCz_ITySPRoFFr_jx-etmPhY3kod7NBi8k2zN9SAlKRRHVZ2z-XSQjP6Jbs5wtZ9Q$> Theme: 3. Volcanic processes Session: Applications, advances and challenges in tephrostratigraphy Explosive volcanism is recorded as tephra layers in a wide range of sedimentary environments (including ocean basins, continents, islands, lakes, and peatlands) and at varying distances from the source (proximal, medial, and distal settings). The study of tephra sequences requires a combination of stratigraphic, geochemical and geochronological tools, and is key to reconstruct eruption histories, ultimately helping to forecast the timing, style and hazards of future volcanic eruptions. Primary tephra layers and cryptotephras are also invaluable for multi-disciplinary studies, allowing for the dating and correlation of volcanic events across regions. However, the incompleteness of volcanic records, dating inaccuracy, reworking, and inconclusive geochemical signatures (among other factors) still represent major challenges in many tephra studies. This session invites contributions on recent applications, advances and challenges in the stratigraphy of individual volcanoes or volcanic regions, and aims to stimulate discussions on new scientific findings and methodologies in tephrostratigraphy.
