摘要：Obsidian, as a natural volcanic glass, was one of the best siliceous rocks available for prehistoric societies for
manufacturing various tools. Due to distinctive trace and rare earth element composition, both its geological
sources and chemical types can be precisely determined. This feature made obsidian an excellent record for
reconstructing its distributions routes, exchange, mobility, communication network and contacts between human
groups. In recent years studies devoted to recognition of obsidian provenance and variant by means of
instrumental, non-destructive methods (i.e. prompt gamma activation analysis – PGAA, energy dispersive x-ray
fluorescence – EDXRF) have been distinctively developed. The strong increase of application this kind of
analyses has been observed also in reference to obsidian archaeological collections from present-day Poland.
The paper aims primarily to give a comprehensive overview of Carpathian obsidian distribution within the
assemblages from Palaeolithic, Mesolithic and Neolithic, registered in Poland. Furthermore, we will focus on
the changeable obsidian flow intensiveness – rather small in the Palaeolithic and Mesolithic to significant
increase in the Neolithic, especially over the time of Malice development.
