Radiocarbon dating and marine reservoir correction of Viking Age Christianburials from Orkney

Dating the earliest Christian burials in Viking Age Orkney is complicated b y marine reservoir effects which can make radiocarbon assays on bone from f ish-eaters appear inappropriately old. This paper provides corrected dates for burials from two chapels which may pre-date the traditional conversion of Scandinavian Scotland and highlights unresolved aspects of calibrating s amples of mixed terrestrial and marine origin.
