摘要：Since 2001, several archaeometrical projects were started on the prehistoric collection of the Hungarian National Museum. The aims of the investigations were to distinguish between macroscopically similar or inadequately identified types of rocks. Further aim is to associate the archaeological finds with potential raw material sources. Among the analytical methods applied, non-destructive Prompt-gamma Activation Analysis has a special importance. Based on major and trace elements, characterisation of stone tools and their raw materials were performed. Until now, more than 300 pieces of various materials (i.e. flint, radiolarite, Szeletian felsitic porphyry, obsidian, etc.) from the Carpathian Basin and from the surrounding areas (Romania, Croatia, Ukraine, Poland and the Mediterranean region) have been analysed, including both archaeological and geological pieces. The characterisation of obsidian and Szeletian felsitic porphyry objects by PGAA is seemingly effective while the identification of the high silica content siliceous rocks, however, is much more difficult
