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. 相似文献
