C14 Radiocarbon Dating - Sample - SUERC-10823

Sample CH06#13 Context 1311 Floor 1311 in House 401 (the lowest floor in the middle roundhouse). Deposit of laminated black and orange lenses of peat ash forming a composite floor layer above sterile windblown sand and sealed by fill layer 1310. This is the basal component of floor 1311, micro-excavated within a 0.5 m square and floated as a sub-layer of 1311. Micro layer 2982/12. Site Phase 9. The carbonised barley grain is most likely to have been deposited as the result of activities within the house in which material became charred from contact with the hearth fire. Very little time is likely to have elapsed between the seed's charring and its incorporation into the archaeological context of the floor deposit.
