摘要: Bone chemical treatment for radiocarbon dating has drawn the attention of different laboratories because dates bones and charcoals found in same layer often disagree. Excluding diet-related reservoir effects, this observation is likely due to a nonoptimized procedure contaminant removal from extracted collagen. In study, systematic work on bone was performed with aim investigate effect each known (i.e. AAA, GEL, ULTR) collagen used 14C dating. Isolation purification lipids animal tissues were estimate eventual offsets induced by applied methods, comparing ages those Moreover, cremated treated first time at CIRCE. Measured isotopic ratios these samples evaluate accuracy against results archaeological context as bones.
