“…The pattern of raw material exploitation is identical, with use of local flint strongly predominating. At Bondi Cave, as at Ortvale Klde (although few "imported" pieces are present in MP layers), obsidian is used increasingly in the UP levels (Le Bourdonnec et al, 2012). The sourcing methods (element compositions, K/Ar series dating) used to correlate obsidian found in Bondi (as well as in Ortvale Klde) and geological sources, demonstrate that the only source unambiguously identified is Chikiani volvano, located more than 120 km SSE of the cave, while some other types would correspond to farther sources in, Armenia, Eastern Anatolia or Azerbaijan.…”
