This is a new and completely revised edition of The Geology of Devon, first published in 1982 and reprinted three times. Each chapter in this new edition has been thoroughly revised and rewritten to reflect the major changes in knowledge since the first edition. There are four additional chapters, on Geological Pioneers, Engineering Geology, Environmental Geology and Off-shore Geology. The book also lists all official and local sites of geological and geomorphological interest and includes an expanded reference list and a colour geological map. The Geology of Devon is aimed at all readers with an amateur or professional interest in geology and undergraduate fieldworkers will find the book particularly helpful. It is a companion volume to The Geology of Cornwall, also published by University of Exeter Press.
