This is a reprint of the second edition of Dr Rayner's standard text on the stratigraphy and historical geology of the British Isles. The book is written for undergraduates and other readers who may have only a general acquaintance with the broad principles of geology. An introductory chapter reviews the basic principles of stratigraphy, geochronology and tectonics. The various geological systems found in the British Isles are then considered in turn. A valuable feature of the book is the extensive treatment of different regional areas within the discussion of a particular geological system. In the final chapter the author reviews briefly those major economic resources that are related to stratigraphy. Throughout the text care has been taken to introduce the plate tectonic interpretation of stratigraphic features. Much more is known about the neighbouring continental shelf and the geology of sea floors and this also is included in order to provide a comprehensive integrated account of the geological history of the British Isles.
