Experimental studies on formation and thermal history of Surtsey.With the aim to provide constraints for a better understanding of the Surtsey eruptions 50 years ago and to find answers to still open questions about the eruption mechanisms, the energetics, and the production of volcanic ash by subaerial and submarine processes, fragmentation experiments will be conducted using representative basaltic melt at magmatic temperatures. The experiments will cover explosive magmatic and phreatomagmatic fragmentation and thermal granulation by non-explosive interaction of melt and watery coolants. Thermal granulation experiments will be performed in a calorimeter, thus information on the thermal history of the products (i.e. hyaloclastites) will emerge. In cooperation with the working group of PI Bach (Univ. Bremen) hydrothermal calorimetric experiments using fresh, experimentally produced glass particles (later also original samples from Surtsey) are proposed to investigate the early post eruptive thermal history, especially the influence of material properties of the deposits and geothermal fluids on the heat transport. This will have particular relevance to reference heat flow models.

Surtsey地层和热史的实验研究。为了更好地了解50年前的苏尔特塞岛火山喷发，并找到关于喷发机制、能量学以及海底和海底过程中火山灰产生的尚未解决的问题的答案，将在岩浆温度下使用具有代表性的玄武岩熔体进行碎片化实验。实验将包括爆炸性岩浆和潜水岩浆碎裂以及熔体和水样冷却剂非爆炸性相互作用的热造粒。热造粒实验将在量热计中进行，因此产品（即透明质碎屑岩）的热历史信息将出现。与PI Bach （Univ. Bremen）工作组合作，提出利用新鲜的、实验产生的玻璃颗粒（后来也包括来自Surtsey的原始样品）进行热液量热实验，以研究喷发后早期的热历史，特别是沉积物和地热流体的物质性质对热传输的影响。这将与参考热流模型特别相关。
