Obsidian exploitation and utilization during the Oldowan at Melka Kunture (Ethiopia)
Résumé
The Oldowan assemblages of Melka Kunture represent so far the earliest known example of utilization of this raw material. The proximity of primary and secondary sources of Balchit obsidian, a high quality raw material easily available in large quantities, is a unique situation in East African Oldowan sites. Obsidian represents indeed a large component of lithic assemblages at Melka Kunture, not only during the Oldowan but during the Acheulian times as well, along with other volcanic rocks like different types of basalts, ignimbrites, trachytes and trachybasalts, which present a completely different aptitude for knapping.
