Thus this variant is much nearer to the Hungarian obsidian varieties in chemical composition, and not so close to Carpathian 1. The obsidian samples analysed from Armenia (samples 105-107) are fairly uniform contrary to previous experience, and can be characterized on the basis of their high Na and Al content, relatively low K and Fe content and their relatively high Ca content. The archaeological samples that were selected as belonging to Carpathian 1 macroscopically, all agree well with the chemical composition of the geological reference pieces of Carpathian 1 obsidians. Measurement series 9 (date: 05/1985) This series comprised mainly samples coming from foreign archaeological sites — from territories where the existence of local obsidian sources has been claimed. Apart from the geological étalons of Carpathian 1 and both Carpatian 2 types, all measurements were performed on samples from archaeological sites outside Hungary. One of the pieces came from Tasád (Tusad), Romania, from a child's grave of the Neolithic period,
