Geochemical sources for the terminal Pleistocene/early Holocene obsidian artifacts of the site of Beseka, central Ethiopia

Twenty obsidian artifacts from the terminal Pleistocene/early Holocene phase of the site of Beseka, central Ethiopia, have been instrumentally characterized using EDXRF and electron microprobe. Results show that most of the artifacts were derived from the silicic centers of Fentale and Kone. A nearby source of Abadir, although with better quality raw material, does not seem to have been utilized.
