摘要：In 2008-2009 we started to work on archaeological obsidians from Croatia and Bosnia-Herzegovina within the
frame of a Croatian-Hungarian project. The main objective of our work was to perform a provenance study of
these obsidian artefacts. The chemical compositions of the systematically collected samples have been
determined non-destructively with Prompt Gamma Activation Analysis. Obsidian is among the important raw
materials of prehistoric tool production in the Carpathian Basin, and a popular subject of archaeometric
studies. According to previous studies, three main groups could be separated. The main categories are the
transparent-translucent Carpathian 1 (C1 – Slovakian) type, the non-transparent Carpathian 2 (C2 –
Hungarian) and the Carpathian 3 (C3) type from Ukraine. In order to determine the origin of obsidian raw
materials, we have analysed Carpathian (C1 and C2) and Mediterranean (Melos, Lipari, Sardinia) geological
samples as well as archaeological pieces from Hungary and Romania. Our PGAA database on obsidian is
continuously expanding with the new analytical results.
In our earlier studies, we concluded that PGAA is suitable for differentiating between various Carpathian and
the Mediterranean obsidians. Adding Croatian and Bosnian archaeological obsidian data to our library, we
found that some of them can be best identified as C1 (Slovakian) and some are chemically similar to the Lipari
obsidians.
