Download or read book The Ice Age written by Jürgen Ehlers and published by John Wiley & Sons. This book was released on 2016-01-19 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a new look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. This period also coincides with important phases of human development from Neanderthals to modern humans, both of whom existed side by side during the last cold stage of the ice age. The ice age has seen dramatic expansions of glaciers and ice sheets, although this has been interspersed with relatively short warmer intervals like the one we live in today. The book focuses on the changing state of these glaciers and the effects of associated climate changes on a wide variety of environments (including mountains, rivers, deserts, oceans and seas) and also plants and animals. For example, at times the Sahara was green and colonized by humans, and Lake Chad covered 350,000 km2 – larger than the United Kingdom. What happened during the ice age can only be reconstructed from the traces that are left in the ground. The work of the geoscientist is similar to that of a detective who has to reconstruct the sequence of events from circumstantial evidence. The book draws on the specialisms and experience of the authors who are experts on the glacial history of the Earth. Readership: Undergraduate and postgraduate students studying the Quaternary, researchers, and anyone interested in climate change, environmental change and geology. The book provides a rich collection of illustrations and photographs to help the readers at all levels visualise the dramatic consequences of glacier expansions during the Ice Age.
Book Synopsis Lake Systems from the Ice Age to Industrial Time by : Daniel Ariztegui
Download or read book Lake Systems from the Ice Age to Industrial Time written by Daniel Ariztegui and published by Springer. This book was released on 2013-03-07 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 20th century, lake research has become an internationally recognised field of scientific activity, improving our understanding on physical, chemical and biological processes, on fresh water ecology, and water resources among others. The interdisciplinary approaches mainly developed in historical research, as performed by archaeologists and earth scientists, to reconstruct the environmental and climate history of the continents, of human settlements and culture, and to evaluate human impact on the local and global environments. The Geological Society of Switzerland publishes in this volume a selected number of contributions presented during a scientific conference on "Lake Systems from Ice Age to Industrial Time" at Yverdon from 17 to 20 October 2001.
Book Synopsis Holocene Delta in Western Lake Geneva and Its Palaeoenvironmental Implications by : Ira Baster
Download or read book Holocene Delta in Western Lake Geneva and Its Palaeoenvironmental Implications written by Ira Baster and published by . This book was released on 2002 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Des investigations sismiques et sédimentologiques ont été entreprises dans le but d'étudier l'évolution sédimentaire de la région au large de Nyon, en relation avec les processus lacustres et les changements climatiques qui ont eu lieu depuis le retrait du glacier du Rhône (18000 années BP) jusqu' à aujourd'hui. La source des sédiments a progressivement changé des eaux de fonte glaciaires aux cours d'eau locaux et un cône deltaïque, alimenté par les apports de la Promenthouse, de l'Asse et du Boiron, a commencé à se former dans la partie occidentale du Lac Léman. D'importants changements des apports sédimentaires ont eu lieu au cours de l'Holocène: six différents lobes deltaïques, progradant sur les sédiments tardiglaciaires, ont été reconnus au milieu du bassin par l'analyse séismostratigraphique. L'étude des propriétés magnétiques des séquences sédimentaires récoltées a fourni une courbe des variations séculaires du champ magnétique terrestre pour les derniers 16000 ans.
Book Synopsis Flood and Megaflood Processes and Deposits by : I. Peter Martini
Download or read book Flood and Megaflood Processes and Deposits written by I. Peter Martini and published by John Wiley & Sons. This book was released on 2009-03-05 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this publication is the understanding of large floods and their impact on the Earth's surface. The major objectives are: 1) to take a second look at what constitutes a megaflood that the principle of uniformitarianism is at some loss to explain and 2) to try to determine what could happen in such large floods by analyzing those that occur in front of glaciers, in alluvial-fans and in alluvial valleys. The products of these floods are presented in terms of sedimentary deposits, erosional features and damage to human activities. The volume bears out the concept that sedimentological analysis can be a powerful tool, not only for reconstructing processes that have acted on ancient landscapes, but also as a technique for risk assessment of certain troubled areas. Therefore, this volume is of interest not only to sedimentologists/gemorphlogists, but also to engineers, landuse planners and anyone interested in the interrelation between humans and the environment. If you are a member of the International Association of Sedimentologists, for purchasing details, please see: http://www.iasnet.org/publications/details.asp?code=SP32

Book Synopsis Geological and Structural Setting, Age, and Geochemistry of the Orogenic Gold Deposits at the Pataz Province, Eastern Andean Cordillera, Peru by : Yves Haeberlin
Download or read book Geological and Structural Setting, Age, and Geochemistry of the Orogenic Gold Deposits at the Pataz Province, Eastern Andean Cordillera, Peru written by Yves Haeberlin and published by . This book was released on 2002 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: La province de Pataz au Nord-Pérou est la plus septentrionale des ceintures paléozoïques d'or, antimoine et tungstène orogéniques (mésothermales) de la Cordillère Orientale des Andes Centrales. Longue de plus de 160 km, elle est connue pour ses veines épigénétiques de quartz aurifères riches en sulfures (ressource : 40 millions d'onces d'or). Les minéralisations, datées à ~314 Ma, sont localisées dans des fractures inverse-décrochantes dextres et d'extension le long des marges et à l'intérieur du batholite de Pataz (329 Ma) et dans les roches métasédimentaires avoisinantes. L'intrusion hôte n'exerce qu'un rôle passif dans leur genèse et fonctionne uniquement comme un réceptacle structural très favorable. La minéralisation est temporellement liée à un stade d'exhumation du bâti et à l'addition d'un flux de chaleur dans une croûte épaissie. Le piégeage de l'or au contact des sulfures microfracturées interviendrait à 5-10 km de profondeur par dilution d'un fluide salin précoce par des eaux superficielles.

Book Synopsis High-resolution Seismic Facies of Alluvial Depositional Systems in the Lower Freshwater Molasse (Oligocene-early Miocene, Western Swiss Molasse Basin) by : Didier Morend
Download or read book High-resolution Seismic Facies of Alluvial Depositional Systems in the Lower Freshwater Molasse (Oligocene-early Miocene, Western Swiss Molasse Basin) written by Didier Morend and published by . This book was released on 2000 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD research showed the contribution of the high-resolution seismic reflection method to the seismic stratigraphic analysis of variable-scale, alluvial depositional systems in the Lower Freshwater Mollasse of the western Swiss Molasse Basin. Seismic data acquired offshore with an airgun source imaged alluvial architectural elements. Metre-thick, channel-fill complexes and flood plain deposits were clearly distinguished. On land, two types of data were recorded, each with a different source : in-hole shotgun and explosives. Data acquired with the former source imaged sandstone-filled multistory channels, but the resolution was not high enough to define their internal structure. The frequency content of the data recorded with explosives did not surely permit the distinction between sandstone- and shale-dominated bodies. More generally, the results demonstrated the potential of the method for predicting subsurface lithologies in cemented fluvial deposits, in association with outcrop and borehole studies.

Book Synopsis Palaeoenvironmental Reconstruction of the Mufara Formation (Upper Triassic, Sicily) by : Alexis Carrillat
Download or read book Palaeoenvironmental Reconstruction of the Mufara Formation (Upper Triassic, Sicily) written by Alexis Carrillat and published by . This book was released on 2001 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude apporte une nouvelle contribution à la reconstruction du cadre géologique et paléoenvironnemental de la Formation Mufara (Trias supérieur, Sicile), et à la compréhension de l'évolution paléogéographique de la Néotethys. Les investigations intègrent l'analyse sédimentologique, l'analyse qualitative et quantitative des palynofaciès, la pyrolyse Rock-Eval, l'analyse des isotopes stables ([delta]13C et [delta]18O), la biostratigraphie haute résolution, et la stratigraphie génétique. L'analyse des palynofaciès et l'analyse des microfaciès ont permis de proposer un nouveau modèle environnemental pour la Formation Mufara. L'étude palynologique indique que les dépôts de la Formation Mufara se sont sédimentés entre le Longobardien terminal/Cordévolien basal et le Tuvalien terminal (Carnien). Quatre assemblages palynologiques ont été mis en évidence à l'intérieur de la phase à "Camerosporites secatus". Les analyses géochimiques associées aux palynofaciès confirment l'origine essentiellement terrestre de la matière organique et indiquent que celle-ci s'est accumulée sous des conditions oxiques à suboxiques.

Book Synopsis 40Ar/39Ar Dating of Late Pleistocene Marine and Terrestrial Tephra from the Tyrrhenian and Ionian Seas, Mediterranea by : Thao Ton-That
Download or read book 40Ar/39Ar Dating of Late Pleistocene Marine and Terrestrial Tephra from the Tyrrhenian and Ionian Seas, Mediterranea written by Thao Ton-That and published by . This book was released on 2001 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce doctorat a permis l'établissement de nouveaux âges 40Ar/39Ar sur des échantillons très jeunes. Le premier chapitre est publié dans "Earth and planetary science letters". Un âge a été obtenu sur un tephra très jeune, provenant des champs phlégréens. Il permet une calibration d'autres événements climatiques et géologiques tels qu'un pic de 10Be (identifié dans des carottes de glace, des océans atlantique, pacifique et méditerranée), une excursion magnétique nommée Laschamp (marqueur global), une calibration des âges 14C>35 ka. Les autres données provenant de l'île de Pantelleria et de tephra marins (mer Ionienne), permettent de comparer des échantillons terrestres et marins. La datation simultanée est un outil puissant pour déterminer la source d'un échantillon marin dont l'origine est incertaine. Une fois la source définie, on peut ensuite facilement travailler sur les échantillons terrestres, disponibles en plus grande quantité et dont les cristaux sont plus grands (datation de monocristaux).
