Since 1980, progress in research on the fission-track dating method and its applications to earth and related sciences has been evaluated during an International Workshop that takes place every four years. This volume contains a selection of papers presented at the International Workshop held in Gent (Belgium) from 26 to 30 August, 1996. Primarily the articles will be of interest to the active fission-track scientists but the combination of research papers and critical reviews that is presented may also provide the interested non-specialist reader with a valuable insight into the fission-track dating method and its role in the earth sciences. This reader will undoubtedly note the evolution that the method has undergone during the last fifteen years, from a technique that was debated in most of its facets to an established chronometric tool with unique qualities in geothermochronology.
Flood Geomorphology describes and analyzes global causes, effects and dynamics of floods and includes methods for related environmental management. It reviews recent advances in the interdisciplinary study of floods and their effects on landforms, sediments, human works, and populations. The use of morphometric parameters of drainage basins is covered and standard procedures for measuring geomorphically significant variables following a major flood are established. Specific chapters present data on the neglected topic of sedimentation in bedrock fluvial systems, and discuss, from the viewpoint of Holocene stratigraphy, common alluvial systems leading to flood plains. The book includes numerous photographs, illustrations and diagrams of flood effects around the world.
The newspaper advertisement for volunteers to accompany Ernest Shackleton on his planned traverse of Antarctica in 1914 was frank in its offering. "Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in event of success." Still, hundreds applied. There were few chances left to be the first to reach the last challenge on Earth. As the 20th Century came of age, explorers had uncovered most of the world's mysteries, sailing to the far corners of the globe, ascending many of its most forbidding peaks, crossing its greatest deserts and penetrating its thickest jungles. Frozen, alien, inhospitable, dangerous, and close to impossible to reach, there were only two tiny dots on the globe that human beings had not yet set foot on--the North and South Poles. The Greatest Polar Exploration Stories Ever Told is a visceral, exciting and stunning collection of twelve stories recounting the bravery, resoluteness, and strength of the men who willingly traversed frozen hells to be the first to reach the North or South Pole. It is a collection that will both inspire and inform--and answer questions about the limits of human endurance. Many men would die during their challenging, frozen journeys, and their deaths were not pleasant. Yet they continued to try again. Here are stories, wrought by the challenging landscape and weather, that made these explorers household names and heroes: Peary, Scott, Amundsen, Shackleton, Franklin, Cherry-Garrard, Scott, Kane, Cook--and others lost to history whose bravery was nonetheless as admirable. Each of these men knew success would bring glory for their countries and financial security and fame and eminent places in history for themselves. Each knew also the odds of success were slim and the chance of dying great. Nations held their collective breaths for news of each expedition and those years later were termed the Heroic Age of Exploration--there were simply no other endeavors that captured the world's attention the various races to the poles. The Greatest Polar Exploration Stories Ever Told recaptures the spirit, drama, and tragedy of a time in history that will never come again.
Recent studies indicate that - due to climate change - the Earth is undergoing rapid changes in all cryospheric components, including polar sea ice shrinkage, mountain glacier recession, thawing permafrost, and diminishing snow cover. This book provides a comprehensive summary of all components of the Earth's cryosphere, reviewing their history, physical and chemical characteristics, geographical distributions, and projected future states. This new edition has been completely updated throughout, and provides state-of-the-art data from GlobSnow-2 CRYOSAT, ICESAT, and GRACE. It includes a comprehensive summary of cryospheric changes in land ice, permafrost, freshwater ice, sea ice, and ice sheets. It discusses the models developed to understand cryosphere processes and predict future changes, including those based on remote sensing, field campaigns, and long-term ground observations. Boasting an extensive bibliography, over 120 figures, and end-of-chapter review questions, it is an ideal resource for students and researchers of the cryosphere.
This significant new book by foremost experts in the field will be the first that truly covers the topic of engineering geomorphology as a distinct discipline and, as such, will be of paramount importance to both practitioners and students. Engineering geomorphology is concerned with the evaluation of landform changes, especially the effects of construction on the environment, notably on the operation of surface processes and the risks from surface processes, whether current processes or the legacies of past processes. Engineering geomorphology provides practical support for engineering decision-making (project planning, investigation, design and construction) and engineering geomorphologists form an integrate part of the engineering or environmental team. Engineering geomorphology has developed in the last few decades to support a number of distinct areas of engineering, including river engineering, coastal engineering, and geotechnical engineering, where engineering geomorphology has complemented engineering geology and has proven to be valuable, especially for rapid site reconnaissance and slope stability studies.Geomorphology provides a spatial context for developing site models and explaining the distribution and characteristics of particular ground-related problems (e. g. landslides, permafrost or the presence of aggressive soils) and resources (e.g. sand and gravel). Engineering geomorphology can also be applied to agricultural engineering, primarily in the investigation and management of soil erosion problems. This book includes basic concepts that underpin efforts to explain the causes, mechanisms and consequences of landform change. It then considers how the land surface works in the context of wetland, flatland, hills, mountains, rivers and coasts; and the techniques that are available to the engineering geomorphologist in the field, in the laboratory, in the office and in the various forms of remote sensing. Each succinct chapter is packed with vital information, well-illustrated with diagrams and tables and fully referenced so that the detail of subject matter can be followed up.
Tuzo is the never-before-told story of one of Canada's most influential scientists and the discovery of plate tectonics, a pivotal development that forever altered how we think of our planet. In 1961, a Canadian geologist named John "Jock" Tuzo Wilson (1908-1993) jettisoned decades of strongly held opposition to theories of moving continents and embraced the idea that they drift across the surface of the Earth. Tuzo tells the fascinating life story of Tuzo Wilson, from his early forays as a teenaged geological assistant working on the remote Canadian Shield in the 1920s to his experiences as a civilian-soldier in the Second World War to his ultimate role as the venerated father of plate tectonics. Illuminating how science is done, this book blends Tuzo's life story with the development of the theory of plate tectonics, showing along the way how scientific theories are debated, rejected, and accepted. Gorgeously illustrated, Tuzo will appeal to anyone interested in the natural world around them.

Dieses Buch soll keine lehrbuch-oder handbuchartige systematische Darstellung und ebensowenig eine fur den Anfanger bestimmte Ein. fuhrung, sondern eine grundsatzliche Erorterung der auf die Ober flachenformen des Festlandes gerichteten Untersuchungen und ihrer Ergebnisse sein. Eine solche grundsatzliche Erorterung ist in einer Wissenschaft dann notig, wenn Arbeitsweise und Auffassung weit aus einandergehen und die Gefahr besteht, dass sie auf ein falsches Geleise kommen. Das ist jetzt in der Lehre von den Oberflachenformen des Landes der Fall. Die Arbeitsweise und Auffassung, die von Amerika zu uns heruber gekommen sind, der sich viele Forscher mit Begeiste rung angeschlossen, und die auch in weiteren Kreisen Verbreitung ge funden haben, scheinen mir, trotzmancher Verdienste im einzelnen, doch im Ganzen der Theorie und namentlich in der Methode verfehlt zu sein. Darum habe ich mich bereits in einer Reihe von Aufsatzen, die seit I9II in der "Geographischen Zeitschrift" erschienen sind, damit auseinandergesetzt und dabei auch andere Grundfragen der Wissen schaft erortert. Das vorliegende Buch fasst nicht nur die genannten Aufsatze, vielfach umgearbeitet, zusammen, sondern vereinigt damit eine ebenso grosse Zahl neuer Aufsatze und stellt so eine grundsatzliche Prufung des ganzen Lehrgebaudes von den Oberflachenformen des Landes dar. Es soll ein Buch der Selbstbesinnung der Wissenschaft sein; man wird begreifen, dass ich dabei gern von personlichen Er fahrungen ausgehe. Ich erhebe nicht den Anspruch, uberall das Rich tige zu treffen; aber ich hoffe, zum Nachdenken anzuregen und den Gesundungsprozess unserer Wissenschaft, der schon eingesetzt hat, zu fordern."
As major actors in the unfolding drama of climate change, glaciers feature prominently in Earth's past and its future. Wherever on the planet we live, glaciers affect each of us directly. They control the atmospheric and ocean circulations that drive the weather; they supply drinking and irrigation water to millions of people; and they protect us from catastrophic sea-level rise. The very existence of glaciers affects our view of the planet and of ourselves, but it is less than 200 years since we realised that ice ages come and go, and that glaciers once covered much more of the planet's surface than they do now. An inspiration to artists, a challenge for engineers, glaciers mean different things to different people. Crossing the boundaries between art, environment, science, nature and culture, this book uniquely considers glaciers from a myriad perspectives, revealing their complexity, majesty and importance, but also their fragility.
Unless they research the subject for themselves, many people do not realise that the origins and development of the human entity are largely an unresolved mystery. Before the Author's own research, he was among them. He found that he also had been subtly indoctrinated with such remarks 'cousins' and 'relatives' with regard to the apes and assumed like most others, that all the facts where in. When you read the work, you will find that this is simply not true. So begins 'The Human Enigma', a truly epic enquiry into the origins of our world and the creatures that walk upon. In particular, it examines the human brain as a uniquely wonderful creation which can be viewed as a gift from God (or was it the gods?) besides Darwinian evolution and Biblical creation. This book explores the fanatic proposition that mankind's rapid development with regard to the human brain may have been influenced by extra terrestrial sources. This work refers to, and draws together the previous work of respected scientists and looks at the future scenarios that the latest genetic and environmental sciences are pointing towards.
Die deutsche und zum groBen Teil die europaische geologische Wissenschaft steht im Gegensatz zur amerikanischen und anglo-indischen den Gedankengangen, die sich mit der Theorie der Isostasie verknupfen, relativ fremd und ablehnend gegenuber. Das hat vor allem darin seinen Grund, weil sich mit dem Wort "Isostasie" der Name DUTTONS assoziiert als des angeblichen Grunders dieser Theorie, gleichzeitig aber auch als des Begrunders der Hypothese der isostatischen Gebirgsbildung. Aber es ist ebenso falsch, DUTTON als Begrunder der Theorie der Isostasie zu feiern - er ist lediglich Erfinder des W ortes "isostasy" - wie die Theorie der Isostasie als Gebirgsbildungstheorie aufzufassen. Die Untersuchung der Faktoren, die zur Gestaltung des Antlitzes der Erde gefiihrt haben, hat erkennen lassen, daB die Formierung der Erdoberflache die Folge eines hochst komplizierten Ineinanderspiels verschiedener Krafte ist. Endogene Energieverschiebungen und kos mische Krafte greifen ineinander, 16sen erdo berflachlich V organge a us, die ihrerseits Ursachen neuer Storungen werden. Sie heben sich in ihren Wirkungen auf oder summieren sich. Von allem Ineinanderspiel sehen wir nur das Ergebnis: die heutige Morphologie der Erdoberflache. Palaogeographische Forschung zeigt uns jedoch bis in ferne geologische Vergangenheit die Veranderungen im morphologischen Bild. Wir erkennen den Wechsel im Relief der Erde, die Verschiebungen von Hoch- und Tiefgebieten. Von den Ursachen dieses Wechselspiels stellt die Hypothese resp."
Your interest is bound to be held by the contents of this work and the amazing characters, their achievements and the other topics dealt with herein. A search team was formed to find any remains of the Ark of Noah. They recorded on tape, the amazing account by an elderly Armenian living in the USA who had climbed onto the petrified hulk of the Holy Ark, when his uncle took him up Mount Ararat as a boy. His recorded account was subjected to the P.S.E Test (Lie Test)and it passed. Read the amazing account of the incredible Count St Germain, philosopher, alchemist and linguist, who could manufacture diamonds and transmute gold and was friend of Louis XV. Voltaire said to him He is a man who knows everything and never dies. He discovered the elixir of youth. Various nobles and dignitaries met him over the decades and he always looked the same. Read about N.D.E's (near death experiences) ghosts, spirits and the paranormal, the Atlantis myth, the story of Noah and more. The title given to this work will now be obvious to all.
Popular culture is flourishing again, with a renewed interest in the ET and UFO phenomena. We are inundated with films, TV programmes and books, plus many conspiracy theories, dealing with the phenomena. Governments and security agencies are denying any interest in the issue, yet releasing masses of documents (mostly unreadable) after being compelled to, by the Freedom of Information Act. Such speculation and documentation in ancient writings suggests that an unearthly presence has been in Earth-space for many generations. The question of this situation must reach a culminating point sometime in the near future. This book is concerned with the cultural shock and social disorientation that would obviously occur with a sudden appearance en-mass of an alien race finally revealing themselves to humanity and how the people of Earth would react.
This thesis encompasses a study of past precipitation patterns based on six cave stalagmites from different parts of the Indian Himalaya. This is the first speleothem study in the Indian Himalaya that shows a direct relationship between past precipitation and the collapse of civilization. The stalagmites examined were KL-3 from Jammu and Kashmir; TCS and BR-1 from Himachal Pradesh; and DH-1, SA-1 and CH-1 from Uttarakhand. Based on the high-resolution palaeoclimatic reconstruction (35 U/th dates, 5 AMS dates, 1,500 samples for 18O and 13C values) obtained for the duration of the Pleistocene-Holocene transition (16.2-9.5 ka BP) and Mid-Holocene-Present (ca. 4.0 ka BP-Present), three major events were identified, namely the Older Dryas (OD), Bolling-Allerod (BA) period and Younger Dryas (YD) at ca. 14.3-13.9, 13.9-12.7 and 12.7-12.2 ka BP, respectively. The study showed a gradual reduction in the precipitation from 4 ka BP onwards for about a millennium with a peak arid period between 3.2 and 3.1 ka BP. According to the findings, the LIA (Little Ice Age) covers a time span from 1622-1820 AD, during which the climate was wetter than that in the post-LIA period (1820-1950 AD). In addition, this thesis supports the assumption that the WDs (Western Disturbances) contribute significantly to the total rainfall in the Himalaya region.
The book summarizes the results of the experimental studies of phase relations in the chemical systems relevant to Earth, carried out by the author in a time period of over 20 years between 1979 and 2001. It is based on 1000 piston-cylinder experiments at pressures up to 4 GPa, and close to 700 experiments carried out with a multi-anvil apparatus at pressures up to 24 GPA. This is the largest published collection of calculated phase diagrams for the chemical systems relevant to Earth. This is also the first time that the phase relations at the relatively low pressures of the lithospheric mantle, mainly applicable to the experimental thermobarometry of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the phase relations of the sublithospheric upper mantle and the uppermost lower mantle, primarily applicable to inclusions in diamond and schocked meteorites. "Tibor Gasparik has devoted his career to determining the high-pressure, high-temperature phase relations of the geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon (NCMAS) oxide system. This book is his opus magnum, summarizing more than 1700 experiments in over 120 figures. ... I have found Phase Diagrams for Geoscientists to be a useful first port-of-call for finding the P-T stability fields ... and I can recommend the book as a reference for geoscientists requiring an overview of the stable phase assemblages in the top 700 km of the Earth." (David Dobson, Geological Magazine, Vol. 142 (2), 2005)
Southern African Geomorphology provides a unique account of the varied physical landscapes of the subcontinent and the landforms which comprise them. It describes these landscapes systematically, and explains their evolution and development against a backdrop of recent trends and new developments within geomorphology. It aims to fill a niche with regard to understanding Earth surface processes and their products in a southern African context. It is an academic text, yet one which will satisfy the lay reader who wishes to learn more about the southern African landscape, and the processes responsible for it. |
