  Abstract:  We measured the significant elements for provenance studies of obsidians by INAA at IBR-2 pulse reactor from, JINR, Dubna, Rusia. The aims of this study are to identification an obsidian source in Orasu Nou (Maramures country from Romania). Comparatively with geological studies, the results of correlation and dendrological diagrams of the analyzed elements from irradiated samples are presented in this paper. Until now the geologist assumed that the obsidian from Oaş area is of a new source. But this isn’t confirmed by our experimental results. By this we can say that in Paleolithic these materials were extracted from Slovakia and they were brought by the river Tisa and exchanged for any kind of products.
