Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The History of Geoconservation written by Cynthia V. Burek and published by Geological Society of London. This book was released on 2008 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to describe the history of geoconservation. It draws on experience from the UK, Europe and further afield, to explore topics including: what is geoconservation; where, when and how did it start; who was responsible; and how has it differed across the world? Geological and geomorphological features, processes, sites and specimens, provide a resource of immense scientific and educational importance. They also form the foundation for the varied and spectacular landscapes that help define national and local identity as well as many of the great tourism destinations. Mankind's activities, including contributing to enhanced climate change, pose many threats to this resource: the importance of safeguarding and managing it for future generations is now widely accepted as part of sustainable development. Geoconservation is an established and growing activity across the world, with more participants and a greater profile than ever before. This volume highlights a history of challenges, set-backs, successes and visionary individuals and provides a sound basis for taking geoconservation into the future.

Download or read book Stratigraphy of the British Isles written by Dorothy Helen Rayner and published by CUP Archive. This book was released on 1981-06-04 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book British Stratigraphy written by Frank A. Middlemiss and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is primarily intended to assist candidates studying geology for the Ordinary Level of G.c.E., and examinations of comparable standard, but it should also be found useful by the" reader requiring a rapid conspectus of the geological history of Britain, and as forming a basis for more advanced work. The scope of the subject matter necessitated a narrow and slippery path be tween over-simplification and excessive detail, but the balance adopted is based upon the experience of many years of teaching at all levels, and of examining for the London G.C.E. Board. The maps, combining outcrop dis tribution with palaeogeography, presented some difficulty, especially for periods of continuously changing geography, such as the Cretaceous. It was necessary in these cases to make an arbitrary choice of one small part of the period, the geography of which could be illustrated. Candidates are advised not to spend time learning every detail of the outcrop patterns, but to con centrate upon the main areas of outcrop. I am indebted to Mrs. Jean Fyffe for the cartographic work.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes a search for geological evidence of meteorite impact structures in Britain. The statistics of impact structures indicate that Britain should have Phanerozoic impact structures up to tens of kilometres in diameter. A constant theme is the importance of atmospheric break-up of small asteroids and comets. These fragmenting bodies produce anomalously shallow craters with low rims and central peaks; three British structures of this type are identified. Analysis of fireball statistics implies that damaging fireball explosions occur over the British Isles on a time-scale of decades. On a time-scale of millennia, however, more damage is done by Atlantic impact tsunami.

Download or read book British Upper Carboniferous Stratigraphy written by C.J. Cleal and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarizes the results of a survey of British Upper Carboniferous sites, undertaken between 1978 and 1990 as part of the Geological Conservation Review (GCR). The GCR was the first attempt to assess the scientific significance of all Britain's geological sites and has proved a landmark in the development of a coherent geological conservation strategy in this country. To ensure that the assessments were based on a firm logical and scientific foundation, the range of scientific interest was divided into ninety-seven discrete subject 'blocks', reflecting the natural divisions of stratigraphy, palaeogeography and geological process; Westphalian stratigraphy and Namurian stratigraphy were two of these blocks. The first stage in the survey was a review of the literature, to establish a compre hensive database of sites. From this, a provisional list of potentially significant sites was made and this was circulated to all relevant specialists in this country and abroad. At the same time, the sites were visited to assess their physical condition and whether the interest was still extant. In some cases, excavation (so-called 'site-cleaning') was carried out to see if the interest of a site could be resurrected or enhanced. The com ments made by the specialists and the field observations were then used to produce a second site list, which again was circulated for comment.
Download or read book Quaternary of South West England written by S. Campbell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: STRUCTURE OF THE VOLUME AND TERMINOLOGY USED This book contains scientific descriptions of 63 localities (Figure A) of at least national importance for Quaternary geology, geomorphology and environmental change in South-West England. These sites were selected by the Geological Conservation Review and are accordingly designated 'GCR' sites. Chapter 1 provides an introduction to the Quaternary. Chapter 2 synthesizes the geomorphological development and Quaternary history of the region, and outlines the principles involved in site selection. The individual GCR site descriptions form the core of the book. In the following chapters, sites are arranged and described in broad geographic areas and by research topic. This is necessitated by the widely disparate nature of the field evidence in Soutb West England: sites demonstrating the full range of Quaternary and geomorphological features are not evenly and conveniently dispersed throughout the region, and some areas have significant gaps. Neither do the individual chapters contain sites that neces sarily equate with particular site selection networks. Rather, the chosen chapter headings provide the least repetitive means of describing the sites and background material. Where possible, a chronological approach, from oldest to youngest, has been used to describe sites within a given chapter. Again, this approach is not always possi ble, and a group of sites may show variations on landform or Stratigraphie evidence broadly within one major time interval or chronostratigraphic stage; inevitably there are many overlaps.
Download or read book Igneous Rocks of South West England written by P.A. Floyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume illustrates some of the significant aspects of magmatic activity from Devonian (408 million years ago) to early Permian (270 million years ago) times in SW England. This period covers the progressive development of the Variscan mountain-building episode, from initial basin formation to final deformation and the subsequent development of a fold mountain belt - the Variscan Orogen. Both extrusive (volcanic) and intrusive (plutonic) rocks are found in the orogen, and chart the various stages of its magmatic development. The sites described in this volume are key localities selected for conservation because they are representative of the magmatic history of the orogen from initiation to stabilization. Some of the earliest volcanic activity in the Devonian is represented by submarine basaltic and rhyolitic lavas developed in subsiding basins, caused by the attenuation of the existing continental crust. In some cases, extensive rifting and attendant magmatism produced narrow zones of true oceanic crust, whereas elsewhere basaltic volcanism is related to fractures in the continental crust at the margins of the basins. After the filling of the sedimentary basins, and their deformation caused by crustal shortening (late Carboniferous Period), further activity is manifested by the emplacement of the Cornubian granites and later minor basaltic volcanism in the early Permian. Accounts of the constituent parts of this history have enriched geological literature from the nineteenth century onwards, and have contributed to the advancement and understanding of magmatic and tectonic processes.
Download or read book Geological History of Britain and Ireland written by Nigel H. Woodcock and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Landscapes and Landforms of England and Wales written by Andrew Goudie and published by Springer Nature. This book was released on 2020-05-10 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the geomorphological diversity of England and Wales. These regions are characterised by an extraordinary range of landforms and landscapes, reflecting both the occurrence of many different rock types and drastic climatic changes over the last few million years, including ice sheet expansion and decay. The book begins by providing the geological and geomorphological context needed in order to understand this diversity in a relatively small area. In turn, it presents nearly thirty case studies on specific landscapes and landforms, all of which are landmarks in the territory discussed. These include the famous coastal cliffs and landslides, granite tors of Dartmoor, formerly glaciated mountains of Snowdonia and the Lake District, karst of Yorkshire, and many others. The geomorphology of London and the Thames is also included. Providing a unique reference guide to the geomorphology of England and Wales, the book is lavishly illustrated with diagrams, colour maps and photos, and written in an easy-to-read style. The contributing authors are distinguished geomorphologists with extensive experience in research, writing and communicating science to the public. The book will not only be of interest to geoscientists, but will also benefit specialists in landscape research, geoconservation, tourism and environmental protection.
