Describes the igneous rocks of Great Britain that formed as a direct result of the Caledonian Orogeny, between 500 and 390 million years ago. Contains 130 detailed GCR site descriptions illustrating the widespread and varied nature of the igneous activity and highlighting critical localities of historical and continuing international importance. The descriptions are linked by chapter introductions that provide more complete discussions of the various sites in their full geological context and the magmatism is related to the overall tectonic history of the orogeny in an introductory chapter. The volume constitutes a comprehensive summary of a major province that has increased worldwide understanding of igneous rocks and their origin since the earliest days of geological investigations.
