Seven pumice samples from excavations in North Sinai have been investigated with respect to their geochemical composition. This type of volcanic rock has been used as an abrasive and thus has been an object of trade since antiquity. With the help of Instrumental Neutron Activation Analysis, six of these Bronze Age samples could be correlated to their volcanic sources on the islands of Santorini, Nisyros and Giali (Greece) using the typical element concentrations ("chemical fingerprint"). The source of one pumice sample remains unidentified excluding, however, the Santorini eruption as a possible source. The concluding section of this article discusses the possible contribution, however indirect, of the pumice from Sinai and elsewhere in the Eastern Mediterranean to the controversial issue of the accurate date of the "Minoan" eruption of Santorini.
对从北西奈半岛发掘出的七个浮石样本进行了地球化学组成方面的研究。这种火山岩一直被用作磨料，自古以来就是贸易对象。借助仪器中子活化分析，利用典型元素浓度（“化学指纹”），其中六个青铜时代的样本可以与希腊圣托里尼岛、尼西罗斯岛和贾利岛的火山源相关联。然而，排除圣托里尼火山喷发作为可能来源后，一个浮石样本的来源仍未确定。本文的结论部分讨论了来自西奈半岛和东地中海其他地方的浮石对圣托里尼岛“米诺斯”火山喷发准确日期这一有争议问题可能产生的贡献，尽管这种贡献是间接的。
