Magma chamber dynamics beneath the Rockeskyller Kopf volcanic centre, West Eifel: A combined field and experimental study

了解岩浆系统的动力学是火山学的一个基本目标。如果要开发喷发预测模型，岩浆流量和在岩浆室中的停留时间是需要估计的重要参数。一种有效的方法是使用反应结构或化学扩散剖面，通过将这些观测与反应动力学的实验数据结合起来，来评估岩浆-矿物相互作用的持续时间。这项研究结合了对西埃菲尔Rockeskyller Kopf火山中心的实地研究，以及随后的实验工作，以校准直接适用于这些岩石的反应。测绘将确定火山历史，并提供一个从与连续喷发事件有关的单位进行采样的框架。来自自然样品的分析数据将与实验结果相结合，以模拟矿工-ALS与熔体之间的接触时间，从而评估Rockeskyller Kopf火山中心生命周期内多个阶段的岩浆停留时间。

Understanding the dynamics of magmatic systems is a fundamental goal in volcanology. Magma fluxes and residence times in magma chambers are important parameters that need to be estimated if predictive models of eruption are to be developed. One powerful approach is to use reaction textures or chemical diffusion profiles to assess the duration of magma-mineral interaction by coupling these observations with experimental data on reaction kinetics. This study combines a field study of the volcanic centre at Rockeskyller Kopf, West Eifel, with subsequent experimental work to calibrate reac-tions that are directly applicable to these rocks. Mapping will establish the volcanic history and pro-vide a framework for sampling from units related to successive eruptive events. Analytical data from the natural samples will be combined with experimental results to model contact-times between miner-als and melt, and therefore assess magma residence times at a number of stages during the lifespan of the volcanic centre at Rockeskyller Kopf.
