En esta nueva edición (cuarta edición española correspondiente a la 21a edición americana del Manual de Mineralogía) se intenta conseguir un equilibrio entre conceptos y principios por una parte y el tratamiento mas descriptivo y sistematico de la Mineralogia por otro.Este objetivo equilibrado requiere el tratamiento de muchos temas. No todos ellos pueden tratarse en un curso de un año y mucho menos en un curso semestral o trimestral. En esta edicion, los capitulos 2 a 9 se refieren a los conceptos, principios y tecnicas.Los capitulos 10 a 13 tratan de la Mineralogia sistematica y descriptiva. El capitulo 14 es una introduccion a la Petrologia y el capitulo 15 ofrece una introduccion a las gemas mas comunes.

El objeto de este libro es analizar diversos problemas desde el punto de vistadel Ingeniero, o precisar algunos aspectos que tienen gran interés para un correcto dimensionamiento de un sistema de tratamiento biologico. Se proporcionan datos practicos de los diversos parametros que influyen en los calculos, aportando los autores su propia opinion sobre los valores mas recomendables que deben adoptarse para un diseño razonable de un tratamiento biologico. Igualmente se ha procurado elegir los valores de las variables mas razonables para facilitar a los tecnicos la acometida al diseño de un proyecto de depuracion biologica. El libro se completa con unos capitulos dedicados a calculos hidraulicos, a pesar del caracter monografico del tema tratado. Se incluyen las formulasde calculo mas usuales, con un apartado dedicado al estudio de los registros de las redes de saneamiento, y otro con el calculo de tuberias de conduccionesde fangos, aspectos que no se encuentran muy frecuentemente en los manuales deHidraulica.INDICE: Medida de contaminacion organica. Principios basicos de la oxidacion biologica. Caracteristicas de las aguas residuales urbanas. Fundamentos de los fangos activados. Eliminacion de la contaminacion organica.

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.

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.

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.

Una colección de cuarenta y siete historias vinculadas de diversas maneras a los volcanes de Islandia, que van desde las aventuras de los primeros colonizadores de la isla hasta las hazañas de exploradores extremos, desde las antiguas sagas nordicas hasta las misiones de la NASA en los cañones lunares de las tierras altas, alternando ciencia, poesia, cronica y leyenda. El Atlas de los volcanes de Islandia es un curioso recorrido por la singularidad geologica de una isla que cuenta con una treintena de sistemas volcanicos activos diferentes, de todos los tipos conocidos. Es el retrato de un pais que es un experimento, primero natural y luego humano, y que por ello ha atraido a lo largo de los siglos a estudiosos, aventureros y poetas, convirtiendose en una fuente inagotable de relatos.
