Abstract
In this paper, the geological and geochemical characterizations of the Kechaldag (a.k.a. Kelbadzhar and Kelbadjar) obsidian source in southwestern Azerbaijan are presented. Samples were collected from primary outcrops, and analyzed by XRF at the University of Missouri Research Reactor. The contents of 12 elements were measured. This allowed us to obtain for the first time a comprehensive geochemical signature of the Kechaldag obsidian source that was less known previously. On the Rb. vs. Sr bivariate plot, Kechaldag is clearly separated from the neighboring Syunik group and other sources of the Lesser Caucasus. The data generated by us can be used for in-depth study of obsidian exploitation in the Paleolithic, Neolithic, and Bronze Age of the Lesser Caucasus and neighboring regions.
