Impact of volcanic climate perturbation caused by Laacher See eruption onto the proximal environment and terminal eruptive mechanisms

Laacher See喷发特别适合于分析喷发期间岩石圈(岩浆室-喷口系统)、水圈(地下水、地表水)和大气(通过气候影响和喷发引发的强降水)之间的高度相关的反馈。Laacher See Tephra现有的粗略的岩石地层划分将被基于事件的地层划分所取代。这一新的框架将允许对喷发历史进行高分辨率的时间评估。对喷发和非喷发事件的更准确的定义反过来将导致对支配喷发高度复杂的演化的内部和外部过程的组合进行更实质性的分析。拟议的工作将包括彻底修订和重新解释现有的大量数据库，并辅之以实地工作和岩相学、岩石学、矿物学和地球化学分析。更好地了解喷发和非喷发的机制及其原因，对于评估普林尼亚喷发对环境的多种影响是重要的。

The Laacher See eruption is uniquely suited to analyze the highly interrelated feedbacks between lithosphere (magma chamber-vent system), hydrosphere (groundwater, surface water) and atmosphere (via climate impact and eruptiontriggered strong precipitation) forcings during the eruption. The existing rough lithostratigraphic subdivision of Laacher See Tephra will be replaced by an eventbased stratigraphic subdivision. This new framework will allow a high-resolution temporal assessment of the eruptive history. A more precise definition of eruptive and noneruptive events in turn will lead to a more substantial analysis of the combination of internal and external processes that have governed the highly complex evolution of the eruption. The work proposed will include a thorough revision and reinterpretation of the existing voluminous database supplemented by fieldwork and lithological, petrographic, mineralogical and geochemical analyses. A better understanding of eruptive and noneruptive mechanisms and their causes is important in assessing the manifold impacts of a Plinian eruption on the environment.
