采用仪器中子活化分析（INAA）测定了希腊爱琴海多个火山源（米洛斯岛、尼西罗斯岛、亚利岛、科斯岛和锡拉岛）的浮石中的 29 种元素，为鉴定考古中发现的浮石和火山灰层奠定了数据基础。锡拉火山“米诺斯喷发”的广泛产物现在可以与所有其他来源清楚地区分开来，并将用于在公元前二千年东地中海地区建立基准线。在来自 Miles 的 14 个样品、来自 Nisyros 的 25 个样品、来自 Yali 的 7 个样品、来自 Kos 的 7 个样品和来自 Thera 的 17 个样品中测定了元素 Al、As、Ba、Ca、Ce、Co、Cr、Cs、Dy、Eu、Fe、Hf、K、La、Lu、Mn、Na、Nd、Rb、Sb、Sc、Sm、Ta、Ti、Th、U、V、Yb 和 Zr。应用两个照射周期和四次测量运行。对结果进行比较，并对每个岛屿典型的合适群体进行分类。由于数据集的可比性不足，之前的研究尚未揭示区分不同来源的标准。这些基本知识被用来将来自 TelI-el-Dab'a（埃及）和青铜时代克诺索斯发掘的浮石与其特定的火山起源联系起来。
instrumental neutron activation analysis (INAA) was used to determine 29 elements in pumice from several volcanic sources (Milos, Nisyros, Yali, Kos and Thera) in the Aegean Sea, Greece, to establish a data basis for the identification of pumice and tephra layers found in archaeological context. The widespread products of the "Minoan Eruption" of the Thera volcano can now be distinguished clearly from all other sources and will be used to establish a datumline in the Eastern Mediterranean Region in the second millenium B.C. The elements Al, As, Ba, Ca, Ce, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Ti, Th, U, V, Yb and Zr were determined in 14 samples from Miles, 25 samples from Nisyros, 7 samples from Yali, 7 samples from Kos and 17 samples from Thera. Two cycles of irradiation and four measurement runs were applied. The results were compared and suitable groups, typical for each island, were classified. Due to insufficiently comparable data sets, the criteria for distinguishing the different sources have not been revealed by previous studies. This basic knowledge was used to relate pumice from excavations in TelI-el-Dab'a (Egypt) and Bronze Age Knossos to their specific volcanic origin.
