This book is one of a popular series that seeks to tell the story of some of Britains most beautiful landscapes. Written with the general reader the walker, the lover of the countryside firmly in mind, these pages open the door to a fascinating story of bygone oceans, deltas, mineralisation and glacial landscapes.Millions of years ago, rocks that now form the lovely terrains of the Moors and Wolds were laid down on the floors of shallow seas, and were then deformed by plate tectonics before being shaped by streams and rivers. The sandstones were left to form the high Moors, whereas the chalk was carved into the rolling Wolds. Ice Age lakes came and went, and all the time wave action was fretting the coastline into glorious and varied profiles.With the help of numerous maps, diagrams and photographs, most of which are taken from his personal collection, geologist Tony Waltham tells the fascinating story of eastern Yorkshire, explaining just how the landscapes of sandstone uplands, chalk hills and clay vales came to look as they do. Including suggestions for walks and places to visit to appreciate the best of the inland and coastal landforms, this accessible and readable book opens up amazing new perspectives for all who are interested in the diverse landscapes of this beautiful area.

From Scafells towering volcanic crags to the deep lake-filled glacial valleys of Wasdale and Buttermere, the Lake District possesses an extraordinary variety of scenery in a relatively small area. This dramatic landscape has inspired writers, climbers, painters, and all who seek the solitude and beauty of the high fells and wish to understand the forces that have shaped this unique place. With over 230 illustrations including maps and superb photographs with unique aerial views and panoramas, it includes: easy-to-understand explanations of how the rocks formed; how the geology affects the landscape and an exploration of the long human story of Lakeland landscapes. There are guided excursions to seven easily accessible geological locations and a dedicated website, with a Google Earth photographic guide to all the main localities mentioned in the book: lakedistrictgeology.co.uk This book will enable you to read the landscape, understand how the regions rocks were formed, how glaciers and rivers sculpted the fells and valleys, and how human interaction with geology and climate has helped to create the Lake District today.

This book is a geological history of Britain from over 2,000 million years ago to the present day and describes the enourmous variety of rocks, minerals and fossils that form this fascinating island.

West Somerset is an area of great geological diversity, straddling the TeesExe Line between highland and lowland Britain. The story of the last 400 million years of Earth history can be gleaned from its rocks: the opening and closing of oceans, the collision of continents and a journey across the Equator. The area may also provide the key to settle the controversy about the origin of South-West England, whose ancient geology is so different from the rest of the country. This unique and diverse geology is also the reason why it is one of the most beautiful and varied stretches of landscape in England. With nearly 170 illustrations, including maps, charts, diagrams and colour photographs, this book describes and explains the evidence for the geological history of the area, from the Palaeozoic, through the Mesozoic to the Pleistocene and Holocene. Regional guides, which discuss the factors that led to the landscape we see today and offer places of interest to visit, cover: the Northern Brendon Hills and Minehead; the Southern Brendon Hills; Wellington and the Blackdown Hills; Wiveliscombe and the Vale of Stogumber; the Quantock Hills; West Somerset coast and the Cannington and Bridgwater Lowlands.

This book is intended to be the most complete and up-to-date guide to the geology and fossils of the New Forest, providing a wealth of information of interest to both the amateur fossil collector and the professional geologist. It includes some 200 field photographs, palaeogeographic maps, digitised borehole/outcrop logs, and geological cross sections. Also included is a tour of the regional geological evolution of southern England since the Permian Period (-280 million years ago), based on deep boreholes and coastal exposures, including the world-famous Jurassic coast of Dorset and east Devon. The author discusses the petroleum geology of southern England and the New Forest and gives a detailed overview of the stratigraphy of the Hampshire Basin, followed by related aspects of economic geology within this area, including ironstones, freshwater aquifers, geothermal energy, sand, clay and peat resources. Finally, there is an up-to-date and complete account of the principal fossil localities, together with a comprehensive gallery of photographs with accompanying descriptions of the most abundant fossils within the New Forest National Park.

The Isle of Wight is a geological gem with its 110km (68 mile) long coastline displaying a range of rocks dating from Lower Cretaceous to Oligocene age. Many of the sands and clays yield fossil bivalves and gastropods, and its famous dinosaur footprints attract much attention from geologists and tourists alike. Yet the scenic beauty of the island is the product of its differing strata, former earth movements and the erosive power of the sea and the rivers. The monoclinal fold that crosses the island forms the chalk downland ridge that ends in the splendid cliffs of Culver in the east and The Needles in the west. By contrast, the softer rocks produce low, slumped cliffs often cut by steep-sided chines or alternatively, on the north coast, branching estuaries and salt marsh creeks. With over 120 colour illustrations this book discusses the geological processes that created the islands distinctive landscape; it provides a field guide to the identification of rocks and fossils and includes details of nineteen itineraries to discover the geological examples and fossils discussed.

This book is one of a popular and exciting series that seeks to tell the story of some of Britains most beautiful landscapes. Written with the general reader - the walker, the lover of the countryside - firmly in mind, these pages open the door to a fascinating story of ancient oceans, deltas, mineralization and tundra landscapes. Over millions of years the rocks that now form the spectacular terrains of the White Peak and the Dark Peak were laid down on the floors of tropical seas and deformed by plate tectonics before being shaped by streams and rivers. The white limestone was fretted into its own distinctive landscape above hidden cave systems; then generations of miners and farmers modified and contributed to the landscapes we see today. With the help of photographs that are largely his own, geologist Tony Waltham tells the remarkable story of the Peak District, explaining just how the landscapes of limestone plateau, grit moors and river valleys came to look as they do. Including suggestions for walks and places to visit in order to appreciate the best of the National Parks landforms, this accessible and readable book opens up an amazing new perspective for anyone who enjoys this varied and beautiful area.

The characteristic landscape of the Lake District is influenced by its geology. The huge array of different rocks found there determines the shape and appearance of the fells and dales. Also, as the dominant building material in the region, rocks impact both the local architecture and the economy through quarrying. A simple easy-to-read guide to the rocks of the English Lake District, with nearly 200 colour illustrations including diagrams, maps and photographs, this book provides an understanding of the main types of rock and characterizes over sixty of the most common rocks. It describes where to find them and how to recognise them in the landscape. Details are given of the use of rocks in local buildings and how the rocks are still quarried today, and finally, their importance to the local economy.

Cada tipo de roca contiene una historia que se entrelaza con la nuestra, moldeando la vida de la Tierra y la de sus habitantes de forma invisible y poderosa. La Tierra se ha reinventado a sí misma durante mas de cuatro mil millones de años, y las rocas han custodiado el registro de toda su existencia. La mayoria de nosotros ignoramos la extraordinaria historia que esconden, porque somos incapaces de interpretar la valiosa informacion cifrada en ellas. Durante las ultimas tres decadas la geologia ha experimentado una revolucion silenciosa, pasando de ser un conjunto gris de datos descriptivos a ofrecer una vision del mundo unificada, capaz de abordar grandes preguntas existenciales sobre los origenes y los posibles destinos de nuestro planeta.De la mano de la geologa Marcia Bjornerud nos adentramos en las atribuladas vidas de las rocas, descubriendo como se entrelazan con las nuestras de maneras sorprendentes, ya que son la infraestructura oculta que mantiene al planeta en funcionamiento, desde los acuiferos de arenisca que purifican el agua que bebemos hasta las formaciones de basalto que regulan lentamente el clima global. Arquitectas de la topografia del mundo y administradoras de la quimica oceanica, las rocas, con sus largas y complejas vidas de miles de millones de años, tienen personalidades propias y distintas, su propio lenguaje. Algunas son extrovertidas, mientras que otras son reservadas y cripticas. Otras son como celebridades, famosas y bellas, aunque de poca importancia funcional para el mundo, mientras que aquellas que parecen simples y aburridas son esenciales para la estabilidad a largo plazo del planeta.En esta apasionada reivindicacion de las piedras y su papel fundamental en nuestro ecosistema, Bjornerud sostiene que los humanos deberiamos sentirnos parte de una comunidad que incluye otros animales, plantas, agua y rocas, y tambien nos invita a sentirnos habitantes de un planeta antiguo y solido como las rocas. Una perspectiva de gran valor en un momento en el que muchos sistemas humanos que alguna vez parecieron robustos muestran signos de fragilidad.
