Book Description
The Advanced Science Institute on which this publication is based took the somewhat unusual form of a geological field symposium held during late August 1984. It was designed to demonstrate to experienced earth scientists from the North Atlantic area the full range of geological phenomena encountered in the British Caledonian rocks. The ASl travelled from South Wales to the far northwest of Scotland by the route shown on the map and in doing so examined sedimentary, igneous and metamorphic rocks from Pembrokeshire (Dyfed), Cardigan (Ceridigian), Snowdonia, Anglesey, the English Lake District and the Southern Uplands and Highlands of Scotland. Thus the fifty or so participants in the ASl studied the geological history and major structures of rocks exposed on either side of the supposed Lower Palaeozoic Iapetus Ocean the British sector of which closed to the south of the present Southern Uplands. Wales (1-5) afforded insight into the nature of the late Precambrian basement of England and Wales and the relationship of sedimentary and volcanic cover sequences to this basement. The Ordovician sequence in Wales is a sample of the volcanic rocks typical of a marginal basin, and were examined in Pembrokeshire and Snowdonia. The English Lake District (6) displays rocks from an island arc also of Ordovician age.

Book Description
This volume deals with those sites selected as part of the Geological Conservation Review (GCR) within the southern British part of the Caledonides, that is, the paratectonic Caledonides - a Caledonian terrane without strong and pervasive deformation and metamorphism, such as occurred further north. This orogenic belt formed by long and complex processes of earth movements between 500 and 380 million years before the present (?late Cambrian to mid-Devonian times), and has been classic ground for geologists for two hundred years. It is perhaps no accident that James Hutton in 1795 chose to illustrate his geostrophic cycle (and unconformity) with three visually explicit examples of the deformation wrought on Lower Palaeozoic rocks by Caledonian events. The former Caledonian mountain chain, which can be seen today in fragmented pieces in Scandinavia, Britain and Ireland, and North America, was ultimately the result of the collision of two continental plates and the closure of a former ocean, Iapetus. Some of these fragments, including those in Scandinavia, southern Britain, and the Republic of Ireland and the Maritime Provinces of Canada, are thought to have lain on the south side of the ocean before collision: the rest of North America, northern Ireland, and Scotland are thought to have lain north of the former Iapetus.

Book Description
This memoir summarizes the current knowledge of New Caledonia’s geology, geodynamic evolution, and mineral resources, based on published and unpublished information. It comprises 10 research papers, each addressing a particular geological assemblage or topic. After an introductory chapter, and a review of the published geodynamic models of evolution of the SW Pacific, chapters 3 to 5 focus on the main geological assemblages of Grande Terre: the Pre-Late Cretaceous basement terranes, the Late Cretaceous to Eocene cover, and the Eocene subduction-obduction complex, one of the largest and best-preserved in the world. Chapter 6 is devoted to the Loyalty Islands and Ridge. Chapter 7 deals with the mostly terrestrial post-obduction units including regolith. Chapter 8 deals with palaeobiogeography and discuss plausible scenarios of biotic evolution. Chapters 9 and 10 provide an comprehensive review of New Caledonia’s mineral resources. The volume will interest stratigraphers, sedimentologists, marine geologists, palaeontologists, palaeogeographers, igneous and metamorphic petrologists, geochemists, geochronologists, and specialists in tectonics, geodynamic evolution, regolith, ophiolites, and economic geology.

Book Description
Britain, Ireland and their surrounding areas have a remarkably varied geology for so small a fragment of continental crust. This region contains a fine rock record from all the geological periods from Quaternary back to Cambrian, and a less continuous but still impressive catalogue of events back through nearly 2500 million years of Precambrian time. This protracted geological history would have been interesting enough to reconstruct if it had been played out on relatively stable continental crust. However, Britain and Ireland have developed instead at a tectonic crossroads, on crust traversed intermittently by subduction zones and volcanic arcs, continental rifts and mountain belts. The resulting complexity makes the geological history of this region at once fascinating and perplexing. Geological History of Britain and Ireland tells the geological story of the region at a level accessible to undergraduate geologists, as well as to postgraduates, professionals or informed amateurs. The book takes a multi-disciplinary rather than a purely stratigraphical approach, and aims to bring to life the processes behind the catalogue of historical events. Full coverage is given to the rich Precambrian and Early Palaeozoic history, as well as to later events more relevant to hydrocarbon exploration. The book is profusely illustrated and contains guides to further reading and full references to data sources, making it an essential starting point for more detailed studies of the regional geology. All British Earth science undergraduates will be required to spend some time studying British Geological History, and this book will be the only one available to British undergraduates The book takes a process-based approach, rather than simply describing the regional stratigraphy Lavishly illustrated with high-quality diagrams

Book Description
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.
