SESSION 6 - Characterising lithic sources
The archaeometric study of obsidian from Gran Canaria (Canary Islands, Spain): new results, new directions

Obsidian was exploited by the original populations on Tenerife, Gran Canaria and La Palma Islands, but no exchange of obsidians has been reported so far. At Gran Canaria, obsidian is found in ignimbritic deposits of small size and the only important sources have been found on Hogarzales and El Cedro Mountains, where numerous mining galleries and mining instruments are known. Besides these, Las Vacas Mountain is also known for the existence of ignimbritic obsidians which were exploited from open air deposits.
