Synthesis of the Caledonian Rocks of Britain


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.




The Geology of Scotland, 4th edition


Book Description

This 4th edition of The Geology of Scotland is greatly expanded from the previous edition with 34 authors contributing to 20 chapters. A new format has been adopted to provide a different perspective on the geology of Scotland. A brief introduction is followed by a chapter outlining some of the important historical aspects that in the 19th century placed Scottish geologists in the forefront of a new science. Scotland is constructed from a number of terranes that finally combined in roughly their present positions prior to about 410 million years ago. Thus the geology of each terrane is described up the time of amalgamation, providing chapters on the Southern Uplands, Midland Valley, Highlands, Grampian and Hebridean terranes. At the end of this section, a brief synthesis summarizes the events that resulted in the amalgamation of the various terranes into the present configuration. Traditional practice is followed in the description of the Old Red Sandstone, Carboniferous, Permo-Trias, Jurassic, Cretaceous, tertiary and Quaternary strata. A separate chapter covers Tertiary igneous rocks. An attempt is made to tell the story of the geological evolution of Scotland, rather than catalogue all areas and formations. Priority is given to the onshore geology, encouraging the reader to go into the field and visit some of the world-class geology on show in Scotland. The chapters are broadly-based, attempting to integrate the sedimentary and igneous histories, and summarize changes in palaeogeography and palaeoenvironments. Economic aspects are covered with chapters on Metalliferous Minerals, Bulk Resources, Coal and Hydrocarbons. A new departure is the chapter on aspects of Environmental Geology and sustainability. Additionally, this publication contains a colour section of 32 plates, illustrating aspects of Scottish Geology, as well as a coloured geological map of Scotland.




Geological History of Britain and Ireland


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













Continental Tectonics and Mountain Building


Book Description

The thematic set of 32 papers in this Special Publication celebrate the 100th anniversary of the 1907 Memoir on The Geological Structure of the North-West Highlands of Scotland by placing the original findings in both historical and modern contexts, and juxtaposing them against present-day studies of deformation processes operating not only in the NW Highlands, but also in other mountain belts.




The Cadomian Orogeny


Book Description




The Geology of Ireland


Book Description

The Geology of Ireland is about the island of Ireland as a physical whole and includes chapters on marine geology and the history of geology in Ireland. The text is intended for professional geologists and students of geology.




Ore Deposits in an Evolving Earth


Book Description

Ore deposits form by a variety of natural processes that concentrate elements into a volume that can be economically mined. Their type, character and abundance reflect the environment in which they formed and thus they preserve key evidence for the evolution of magmatic and tectonic processes, the state of the atmosphere and hydrosphere, and the evolution of life over geological time. This volume presents 13 papers on topical subjects in ore deposit research viewed in the context of Earth evolution. These diverse, yet interlinked, papers cover topics including: controls on the temporal and spatial distribution of ore deposits; the sources of fluid, gold and other components of orogenic gold deposits; the degree of oxygenation in the Neoproterozoic ocean; bacterial immobilization of gold in the semi-arid near-surface environment; and mineral resources for the future, including issues of resource estimation, sustainability of supply and the criticality of certain elements to society.
