Abstract

Ten fragments of bronze age frescoes from the Greek group of volcanic islands known as Santorini have been examined by powder X-ray diffraction. A qualitative phase analysis based on line positions only was supplemented by the Rietveld method which uses complete diffraction profiles to increase the credibility of the phase analysis.
