2006 m. Nr. 4 Siliceous rocks as a raw material of prehistoric artefacts in Lithuania
The goal of the project and all the work was to establish the distribution, composition,
origin and possible directions of transportation of prehistoric siliceous (flint) artefacts in Lithuania. Siliceous concretions and nodules from outcrops and quarries, artefacts from well-investigated Stone Age ancient settlements (Margionys, Kretuonas, Jara, Biržulis, etc.) stored at the funds of Lithuanian museums were surveyed and petrographically described. For revealing the distinctions in the composition of siliceous rocks and distribution of major and trace elements, the samples were analysed by Direct Current Arc Emission Spectrophotometry. The data processing by statistical methods (correlation and cluster analysis) allowed a conclusion that siliceous artefacts could belong to three genetic types of raw material. The artefacts of Margionys ancient settlement can be identified as made of local flint concretions. However, the raw material of Biržulis artefacts is presumably of two types: flint concretions imported from the south and the local stratified flint (silicified gaize). The raw material of Kretuonas and Jara artefacts is also of two genetic types: imported Upper Cretaceous flint from the south south east and the relatively local Upper Devonian siliceous rocks.
