SUMMARY:Geology of Stonehenge and the bluestone controversy
DESCRIPTION:talk given by Prof. Peter Worsley\, Emeritus Professor of Quaternary Geology\, University of Reading \nAbstract \nStonehenge has recently come into the public eye due to the publication of the results of new geochemical work.  The Sun newspaper declared ‘Mystery of where the giant rocks came from SOLVED’ whereas The Guardian was more cautious with a headline ‘Archaeologists discover likely source of Stonehenge’s giant sarsen stones’.  The senior English Heritage properties historian said that she was delighted that one of the most intriguing questions about Stonehenge had been answered.  The background to this ill-judged euphoria will be critically examined and the geological fundamentals reviewed. \nApart from the sarsens\, the other geological problem lies with the assemblage of ‘foreign’ rocks incorporated into the henge structure\, i.e. the so-called Bluestones.  There now appears to be little doubt that the Bluestones are primarily derived from outcrops in south-west Wales but the mechanism whereby they arrived to Salisbury Plain are far from being resolved.  Most archaeologists have accepted the hypothesis that Neolithic people were responsible for the transport of the lithostats from their source to the plain but over time the favoured routes have changed drastically.  In contrast geologists have been split between those who accept the human transport mode and those who favour natural earth surface processes as being responsible for transportation – glaciation.  The strengths and weaknesses of these competing ideas will be assessed.
