This work reviews the correlation of the British and Irish Cambrian with the current (though incomplete) international standard for the Cambrian. Since the earlier edition of 1972, the basal and upper limits of the Cambrian system have been internationally agreed; so this account excludes Tremadocian rocks but includes some that were formerly considered Neoproterozoic. Half of the series and stage subdivisions are internationally agreed, but for the undefined divisions of the Cambrian the standard used here makes use of data from Avalonian successions. Since the first edition was published, almost every aspect of the Cambrian in the British Isles has been subjected to new study. Here, the plate tectonic make-up of the British Isles is reviewed, new radiometric ages and isotopic studies are summarized and the biostratigraphy is enhanced by the study of acritarchs, especially in the Irish successions.

&Quot;This Report is revised and expanded from the 1972 publication, providing an up-to-the-minute account of the British Ordovician formations and their correlation nationally and internationally. It also includes the most comprehensive treatment of Ireland ever attempted. The reference list is a comprehensive bibliography of papers on the subject published since 1970.". "This Special Report will be a valuable reference for research and applied geoscientists working with rocks of Ordovician age. It will be of particular interest to those working in, or visiting, the Welsh mountains and the English Lake District."--BOOK JACKET.
Britain and Ireland have a remarkably varied geology for so small a fragment of continental crust, with a fine rock record back through three billion years of geological time. This history would have been interesting enough if it had been played out on relatively stable continental crust. However, Britain and Ireland have developed at a tectonic crossroads, on crust once traversed by subduction zones and volcanic arcs, continental rifts and mountain belts. The resulting complexity is instructive, fascinating and perplexing. Geological History of Britain and Ireland tells the region's story at a level accessible to undergraduate geologists, as well as to postgraduates, professionals or informed amateurs. This second edition is fully revised and updated, reflecting our continually developing knowledge of the region's geology. Full coverage is again given to the rich Precambrian and Early Palaeozoic history, as well as to later events more relevant to hydrocarbon exploration. The book is an essential starting point for more detailed studies of the regional geology. Additional resources for this book can be found at: http://www.wiley.com/go/woodcock/geologicalhistory
This second edition of 'The Geology of England and Wales' is considerably expanded from its predecessor, reflecting the increase in our knowledge of the region, and particularly of the offshore areas. Forty specialists have contributed to 18 chapters, which cover a time range from 700 million years ago to 200 million years into the future. A new format places all the chapters in approximately temporal order. Both offshore and economic geology now form an integral part of appropriate chapters.
