Site Event/Activity record ESF26161 - Tree-ring Analysis - Norton Hall Barn, Hall Lane

Denrochronological analysis was request following the provision of a Historic England repair grant, to provide independent dating evidence. Twenty-four core samples were taken from primary phase timbers of the roof and wall framing and a further 12 from timbers associated with later alterations relating to the doorways. Each sample was given the code NRT-N. Four of the samples, one from the primary phase timbers and 3 from timbers associated with the doorways had too few rings for secure dating and so were rejected. Felling date ranges and terminus post quem dates for felling have been calculated using the estimate that 95% of mature oak trees from this area have between 15 and 40 sapwood rings. Three site sequences were seen NRTNSQ01 for the primary timbers, NRTNSQ02 for the alteration timbers and the third site sequence, containing samples taken from two studs thought to be associated with the primary construction phases, is undated.
