Book excerpt: Although a small country, Scotland’s geology is complex, internationally renowned and offers an accessible outdoor research laboratory and training ground for earth science. The onshore and offshore geology together encompass examples of all Earth’s geological periods and preserve many classic examples of sedimentary basins and orogenic belts. Palaeontological findings have provided key evidence for the evolution of life. With a wide spectrum of contributors, full-colour figures and photographs and, for each chapter, a Topic Box highlighting key research developments and challenges, this 5th edition of The Geology of Scotland represents a major update and expansion from the 4th edition. A revised Introduction summarizes the geological evolution of Scotland, the nature of the crust and the societal relevance of geology to climate change and sustainability. The final three chapters provide a modern view on energy, water and minerals, environmental concerns and geoconservation. The intervening chapters cover the geological periods, including much new geochronological data and exciting new palaeontological discoveries.
