圣托里尼岛大规模爆发的浮岩产物在光学外观和化学成分上都显示出高度的相似性。对这些喷发产物进行明确分类的需求是从考古研究中提出的，其中浮石可以被解释为“喷发后”的时间标记。这项工作的目的是寻找因地球化学过程而发生重大变化的元素，这些元素可以指示五次主要爆炸性喷发所产生的浮石的区别。INAA的25个元素可以明确的分类，并提供了新的信息，圣托里尼火山的化学演化。
The pumiceous products of the large-scale explosive eruptions at Santorini show a high grade of similarity in their optical appearance as well as in their chemical composition. The demand for a clear classification of these eruption products was raised from archaeological research, where pumice can be interpreted as a "post-eruption" time marker. The aim of this work was to find elements that underwent significant changes because of geochemical processes and that could be indicative for a distinction of pumice produced by the five major explosive eruptions. INAA of 25 elements allows a clear classification and contributes new information to the chemical evolution of Santorini volcano.
