Newgrange Geology
The majority of the stones at Newgrange including most of the kerbstones are Greywacke, a variety of sandstone found on the coast at Clogher Head, north of Newgrange. Geraldine Stout in Newgrange and the Bend of the Boyne states "This type of rock weathers well and provides a good surface for decorating; it is the favoured stone type of the tomb builders. Given the quantity of stone used (c.200,000 tonnes) there must have been organised extraction of this material. Recent research suggests that the greywacke was quarried.
Similar stone has been identified in the Lower Palaeozoic Silurian zone which runs between counties Longford and Down and extends to within five kilometres of the area. The precise location of these prehistoric quarries has yet to be discovered. The maximum depth of these deposits does not exceed three metres, so exploitation of many sites would have been necessary. Primitive quarries, if backfilled, would not be easily noticed today"
