Project TIME will be using innovative sampling and measurement methods to produce hundreds of new radiocarbon measurements from sites dating to the period 3500–1500 BC. The sites selected for new measurements (see ‘sites’ page) are the locations of enclosures (including ‘henges’), stone circles, timber circles, occupation sites and other locations which have not yet been dated with precision, but offer great potential to provide detailed chronological information about human lives and activities
one of their chosen sites is Bryn Celli Ddu a famous passage tomb on the island of Anglesey off the north Wales coast. As such it represents one of the few examples of such monuments outside the concentrations on the Orkney Isles and the famous examples in Co. Sligo and Co. Meath in Ireland. Passage tombs have common features including famous rock art panels and the solar alignments noted at Newgrange and Maes Howe.
GeoMon’s interest in Bryn Celli Ddu is the use of blue [glaucophane] schist, a very rare rock type which is actually abundant locally.
