CHARACTERIZATION OF OBSIDIAN FOUND IN ROMANIA BY NEUTRON ACTIVATION METHOD

Significant elements for provenance studies on obsidians were measured by INAA at IBR-2 pulse reactor from JINR, Dubna, Rusia. The aims of this study were to identify an obsidian source in Orasu Nou (Maramures County, Romania). Comparatively with geological studies, new results of correlation and dendrological diagrams of the analyzed samples are presented. So far, the geologists assumed that the obsidian from Oas area (from Romania) is a new source, but this was not confirmed by our experimental results. We can therefore conclude that in Paleolithic these materials were extracted from Slovakia and were brought by the river Tisa and exchanged for any kind of products.
