From Pembrokeshire to Stonehenge
Anew paper in Archaeology in Wales, produced by Dr Rob Ixer of Leicester University and Dr Richard Bevins of Amgueddfa Cymru – National Museum Wales confirms, for the first time, the exact origin of some the rhyolite debitage found at Stonehenge. This work could now lead to important conclusions about how stones were transported from Pembrokeshire to Stonehenge.
Over a period of nine months, Bevins and Ixer have been carefully collecting and identifying samples from rock outcrops in Pembrokeshire to try and locate the provenance of rocks that can be found at what is today, one of the world’s most iconic archaeological sites.
Their recent discovery confirms that the Stonehenge rhyolite debitage originates from a specific 70m long area namely Craig Rhos-y-felin near Pont Saeson. Using petrographical techniques, Ixer and Bevins found that 99% of these rhyolites could be matched to rocks found in this particular set of outcrops. Rhyolitic rocks at Rhos-y-felin are distinctly different from all others in South Wales, which gives almost all of Stonehenge rhyolites a provenance of just hundreds of square metres.
