Tree-Ring Analysis of Timbers from the roof of St Margaret's Chapel, St Nicholas' Cathedral, Newcastle upon Tyne, Tyne and Wear

Summary Twelve samples from the roof timbers of St Margaret's Chapel in St Nicholas' Cathedral, Newcastle upon Tyne, were analysed by tree-ring dating. This analysis produced a single site chronology of 11 samples, having a combined overall length of 302 rings long. Neither this site chronology, or the remaining single ungrouped sample, could be dated against any available reference chronology. It is possible that the climatic data of the site chronology is not represented in any reference material. This is possibly because the trees used in the roof are from an isolated source in Britain or, possibly, the timbers have been imported from an area abroad for which reference data is currently unavailable.
