The motivation for this volume came from the idea that the Precambrian is the key, both to the present, and to the understanding of the Earth as a whole. The Precambrian constitutes about 85% of Earth's history, and of that, about 3.75 billion years of Precambrian time, represented by rocks, are accessible to geoscientists. Ancient atmospheric and environmental conditions can be traced back to the time when the Earth was only about 250 million years old. Precambrian rocks supply almost 75% of important mineral resources such as Fe, Mn, Au, Pt and Cr. Many of these elements are associated with sedimentary rocks and some important hydrocarbon, coal and graphite deposits are also hosted by Precambrian rocks.

This volume is aimed at geoscientists interested in Precambrian sedimentary rocks and at students of Earth history. It contains review articles discussing Precambrian conditions and case studies from Precambrian shields and successions of North and South America, Australia, Africa, Europe, Asia and India. The introductory papers, written by experts on Precambrian environments, treat comprehensively the application of actualism to the Precambrian, the evolution and influence of life on the sedimentary rock record, the genesis of Banded Iron Formations, the Precambrian sulphur cycle and the significance of Precambrian chemical carbonate precipitates. The case studies include depositional settings and processes in Archean terranes, in Paleoproterozoic sequences, with some emphasis on the lack of vegetation and weathering, and in late Proterozoic sequences, with some emphasis on glacial deposits. The contributions demonstrate that Precambrian sedimentary deposits are commonly similar to their Phanerozoic counterparts in terms of composition, sedimentary processes, and depositional setting, but may differ significantly as a result of lack of vegetation, climatic and biological constraints, composition and circulation of seawater, and the secular involvement of continental crust.

The written history and archaeological records of Central Scotland takes us back to Pictish times some 5,000 years ago. The geology of the area stretches back a further 400 million years. The oldest rocks are found near Lesmahagow and in the Pentland Hills. Known geologically as 'inliers'- small areas of rocks from an older age, surrounded by younger strata - these strata have yielded some of the oldest fish on earth and are highly prized for what they tell us about early life on the planet. Rocks of the Old Red Sandstone and the succeeding Carboniferous era underlie the rest of Central Scotland in almost equal measure. Explosive volcanic rocks, thick layers of lava, desert sandstones, limestones and productive coal measures make up this bedrock patchwork. Then, sometime later, a covering of ice, some two kilometres thick, blanketed the landscape. It sandpapered and burnished the bedrock into the familiar scenes we see today - our matchless Scottish landscape. The coal and iron ore which lay beneath the ground between Edinburgh and Glasgow provided the raw materials that drove the Industrial Revolution in Scotland, and the early focus on understanding the rocks beneath our feet was unsurprisingly initially concentrated on the most useful minerals resources.

The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with "The Lost World of Fossil Lake", one of the world's leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered there with an explanation of their evolutionary significance, Lance Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we've learned from them. Grande presents a broad range of fossilized organisms from Fossil Lake - from single-celled algae to palm trees to crocodiles - and together they make this long-extinct community come to life in all its diversity and splendor. A field guide and atlas round out the book, enabling readers to identify and classify the majority of the known fossils from the site. Lavishly produced in full color, "The Lost World of Fossil Lake" is a stunning reminder of the intellectual and physical beauty of scientific investigation-and a breathtaking window onto our planet's long-lost past.

There have been significant changes in sea level over the past two million years, and a complete understanding of natural cycles of change as well as anthropogenic effects is imperative for future global development. This book reviews the history of research into these sea-level changes and summarises the methods and analytical approaches used to interpret evidence for sea-level changes. It provides an overview of changing climates during the Quaternary, examines processes responsible for global variability of sea-level records, and presents detailed reviews of sea-level changes for the Pleistocene and Holocene. The book concludes by discussing current trends in sea levels and likely future sea-level changes. This is an important and authoritative resource for academic researchers and graduate and advanced undergraduate students working in tectonics, stratigraphy, geomorphology, physical geography, environmental science and other aspects of Quaternary studies.

Longlisted for the Highland Book Prize 2019 The rocks of northern Scotland tell of turbulent events involving continental collisions that unleashed cataclysmic forces, creating a chain of mountains, the remnants of which we see today on both sides of the Atlantic. Geologists from Victorian times onwards have studied the area, and some of the most important geological phenomena have been established and described from the rocks that built these stunning landscapes. In this book, Alan McKirdy makes sense of the many and varied episodes that shaped the familiar landscape we see today. He highlights a number of fascinating geological features, including the Old Red Sandstones of Cromarty and the Black Isle, which carry the secrets of life during 'the Age of Fishes', and the thin sliver of fossil-bearing strata which hugs the coast from Golspie to beyond Helmsdale that dates back to Jurassic times and which records the time when dinosaurs roamed the Earth.

How do high mountain ranges form on the face of the Earth? This question has intrigued some of the greatest philosophers and scientists, going back as far as the ancient Greeks. "Devil in the Mountain" is the story of one scientist, author Simon Lamb, and his quest for the key to this great geological mystery.

Lamb and a small team of geologists have spent much of the last decade exploring the rugged Bolivian Andes, the second highest mountain range on Earth--a region rocked by earthquakes and violent volcanic eruptions. The author's account is both travelogue and detective story, describing how he and his colleagues have pursued a trail of clues in the mountains, hidden beneath the rocky landscape. Here, the local silver miners strive to appease the spirit they call Tio-the devil in the mountain.

Traveling through Bolivia's back roads, the team has to cope with the extremes of the environment, and survive in a country on the verge of civil war. But the backdrop to all these adventures is the bigger story of the Earth and how geologists have gone about uncovering its secrets. We follow the tracks of the dinosaurs, who never saw the Andes but left their mark on the shores of a vast inland sea that covered this part of South America more than sixty-five million years ago, long before the mountains existed. And we learn how to find long lost rivers that once flowed through the landscape, how continents are twisted and torn apart, and where volcanoes come from.

By the end of their journey, Lamb and his team turn up extraordinary evidence pointing not only to the fundamental instability of the Earth's surface, but also to unexpected and profound links in the workings of our planet.

Quaternary of the Levant presents up-to-date research achievements from a region that displays unique interactions between the climate, the environment and human evolution. Focusing on southeast Turkey, Lebanon, Syria, Jordan and Israel, it brings together over eighty contributions from leading researchers to review 2.5 million years of environmental change and human cultural evolution. Information from prehistoric sites and palaeoanthropological studies contributing to our understanding of 'out of Africa' migrations, Neanderthals, cultures of modern humans, and the origins of agriculture are assessed within the context of glacial-interglacial cycles, marine isotope cycles, plate tectonics, geochronology, geomorphology, palaeoecology and genetics. Complemented by overview summaries that draw together the findings of each chapter, the resulting coverage is wide-ranging and cohesive. The cross-disciplinary nature of the volume makes it an invaluable resource for academics and advanced students of Quaternary science and human prehistory, as well as being an important reference for archaeologists working in the region.

Fossils have been vital to our understanding of the formation of the earth and the origins of all life on it. However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this delightful book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are 'living fossils'? What fossils will we leave behind for future generations to examine? Building on the scientific aspects, he places fossils in a very human context, highlighting their impact on philosophy and mythology, our concept of time, and today's popular culture. What quickly becomes obvious is that the discovery of fossils and the ways in which they have been interpreted over time makes for fascinating reading. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Many people appreciate the stunning vistas of the Great Basin desert; understanding the region’s geological past can provide a deeper way to know and admire this landscape. In The Great Basin Seafloor, Frank DeCourten immerses readers in a time when the Basin was covered by a vast ocean in which volcanoes exploded and sea life flourished. Written for a nontechnical audience, this book interprets the rock record left by more than 500 million years of oceanic activity, when mud and sand accumulated and solidified to produce today’s Great Basin across parts of modern Utah, Nevada, and California. DeCourten deciphers clues within exposed slopes and canyons to reconstruct the vanished seafloor and its volcanic events and examines fossils to reveal once-thriving ancient marine communities. Supplemental material is available online to serve as a field guide for readers wishing to explore this ancient ocean themselves as they travel through the region.

Plate tectonics is a revolutionary theory on a par with modern genetics. Yet, apart from the frequent use of cliches such as 'tectonic shift' by economists, journalists, and politicians, the science itself is rarely mentioned and poorly understood. This book explains modern plate tectonics in a non-technical manner, showing not only how it accounts for phenomena such as great earthquakes, tsunamis, and volcanic eruptions, but also how it controls conditions at the Earth's surface, including global geography and climate. The book presents the advances that have been made since the establishment of plate tectonics in the 1960s, highlighting, on the 50th anniversary of the theory, the contributions of a small number of scientists who have never been widely recognized for their discoveries. Beginning with the publication of a short article in Nature by Vine and Matthews, the book traces the development of plate tectonics through two generations of the theory. First generation plate tectonics covers the exciting scientific revolution of the 1960s and 1970s, its heroes and its villains. The second generation includes the rapid expansions in sonar, satellite, and seismic technologies during the 1980s and 1990s that provided a truly global view of the plates and their motions, and an appreciation of the role of the plates within the Earth 'system'. The final chapter bring us to the cutting edge of the science, and the latest results from studies using technologies such as seismic tomography and high-pressure mineral physics to probe the deep interior. Ultimately, the book leads to the startling conclusion that, without plate tectonics, the Earth would be as lifeless as Venus.

This book highlights the knowledge about landscapes and characteristics of the earliest hunter-gatherer lifeway in Southern Patagonia. It presents an analysis of the archaeological investigations carried out during three decades by an interdisciplinary team that involved archaeologists, anthropologists, paleontologists, geologists and specialists in pollen and diatoms. The database yielded was recovered from systematic survey and excavations from the Pleistocene and Holocene stratigraphic layers of the rockshelter known as AEP-1, Piedra Museo Locality, situated in the central plateau of Santa Cruz Province, Argentina. Piedra Museo is a unique place in the world of high academic interest with some of the earliest archaeological remains in the Americas. Researchers defined two strata and several Stratigraphic units in the site based on the sedimentological and pedological characteristics. The depositional zones contain archaeological remains that are interpreted as hunting events corresponding to two main different occasions in the human colonization of the region, and a third human occupation during the Middle Holocene. Last one occurred then of the massive rockshelter roof colapse. The faunal remains led to a new approach to the palaeoenvironmental evolution of this enclosed basin. This volume describes the management of lithic raw materials and social networks from first human occupation of the Patagonian region to territorial consolidation of hunter-gatherer societies.

In this attractively illustrated volume, eminent biologist Sir Richard Southwood offers a remarkable survey of life in all its forms, ranging from the earliest single-celled bacteria, to the evolution and extinction of animals such as the dinosaurs, to the variety of life today.
The book follows the major geological periods--such as the Cambrian, Ordovician, Silurian, and Devonian--explaining how great planetary changes such as the movement of the continents, the rising and falling of sea level, and the periods of glaciation, affected the forms of life on Earth. Beginning with the earliest and simplest forms of life, Southwood discusses such amazing creatures as bacteria that live around geysers and thermal vents and can survive in boiling water. He explains how the development of skeletons triggered the Cambrian Explosion, when animals such as trilobites, sea scorpions, shellfish, cephalopods first spread around the earth. He also examines such landmarks of evolution as the appearance of eggs in shells and of insects in flight. We read about the great dinosaurs and the arrival of the mammals and the primates, and the great extinctions, including the Permian (the largest in fossil history, wiping out 95% of animals) and the Cretaceous/Tertiary (K/T) extinction (the one that wiped out the dinosaurs). Southwood concludes by examining the impact of humanity on Earth, considering if we ourselves might not unleash the next major extinction.
Southwood's love for his subject, for the life he describes so vividly, shines through this carefully crafted story. Generously illustrated with line drawings showing the fauna and flora of the Earth, both past and present, The Story of Life will enthrall anyone interested in nature and natural history.

The monograph presents the results of studies of the organization of terrestrial geo (eco-) systems in the Pacific mobile belt - the tectonically and climatically active zone of contact between the mainland and the ocean, creating new land areas. A detailed evolutionary landscape-ecological concept based on a discrete empirical-statistical modeling of forest natural complexes at various stages of the geological history of the formation of the continental biosphere in the Northwest Pacific is presented. Based on the materials of large-scale landscape surveys conducted at experimental ranges, three spatiotemporal sections are described with a common trajectory of subaerial landscape genesis: 1) neo-specific, progressive - the stage of nucleation and upward evolution of volcanogenic island-arc geosystems of the Neogene-Quaternary age in the ocean environment, with the formation at the local level of the beginnings of zonal types of geographical environment and with the emergence of "climate unjustified" highly productive forests due to geothermal th power of active volcanoes; 2) subpacific marginal continental - the stage of their subsequent continental development as a young (Mesozoic) mountain-valley morphostructure, with the formation of buffer forest communities of evolutionary menopause; 3) subpacific regressive - the final stage of decaying evolution, due to the fragmentation and sinking of the marginal parts of the material, with the advent of continental islands with a "decrepit" denudation relief, active exogenous morpholithogenesis and a simplified structure of the forest cover. The climatic-genetic mechanisms of evolutionary landscape-ecological processes in various sectors of the Pacific megaecoton are described using simulation of these processes according to landscape forecasts for the next 100-200 years. According to the stability parameters of forest communities, chronological regularities of climatogenic phytocenotic transformations in the island-arc and marginal continental landscapes are revealed.

Resolution of the sixty year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth Science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revolutionary theory. Based on extensive interviews, archival papers and original works, Frankel weaves together the lives and work of the scientists involved, producing an accessible narrative for scientists and non-scientists alike. This second volume provides the first extensive account of the growing paleomagnetic case for continental drift in the 1950s and the development of Apparent Polar Wander Paths that showed how the continents had changed their positions relative to one another more or less as Wegener had proposed. Paleomagnetism offered the first physical measure that continental drift had occurred and helped determine the changing latitudes of the continents through geologic time.

Orogenesis, the process of mountain building, occurs when two tectonic plates collide - either forcing material upwards to form mountain belts such as the Alps or Himalayas or causing one plate to be subducted below the other, resulting in volcanic mountain chains such as the Andes. Integrating the approaches of structural geology and metamorphism, this book provides an up-to-date overview of orogenic research and an introduction to the physico-chemical properties of mountain belts. Global examples are explored, the interactioning roles of temperature and deformation in the orogenic process are reviewed, and important new concepts such as channel flow are explained. This book provides a valuable introduction to this fast-moving field for advanced undergraduate and graduate students of structural geology, plate tectonics and geodynamics, and will also provide a vital overview of research for academics and researchers working in related fields including petrology geochemistry and sedimentology.

Rock fractures control many of Earth's dynamic processes, including plate-boundary development, tectonic earthquakes, volcanic eruptions, and fluid transport in the crust. An understanding of rock fractures is also essential for effective exploitation of natural resources such as ground water, geothermal water, and petroleum. This book combines results from fracture mechanics, materials science, rock mechanics, structural geology, hydrogeology, and fluid mechanics to explore and explain fracture processes and fluid transport in the crust. Basic concepts are developed from first principles and illustrated with worked examples linking models of geological processes to real field observations and measurements. Many additional examples and exercises are provided online, allowing readers to practise formulating and quantitative testing of models. Rock Fractures in Geological Processes is designed for courses at the advanced undergraduate and graduate level but also forms a vital resource for researchers and industry professionals concerned with fractures and fluid transport in the Earth's crust.

The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged.
The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course.
This book places humanity in context as part of the Earth system, using a new scientific synthesis to illustrate our debt to the deep past and our potential for the future.

In revising his now classic work on the geology of North America, Philip B. King has devoted attention both to the new concepts of global tectonics and to new facts obtained from fieldwork in recent years. From its overview of the natural history of continents, to the sections describing the characteristics and history of each region, this remains a fundamental text on continental geology. Originally published in 1977.

Written in 1912 by the Cambridge scholar and mathematician Charles Davison, The Origin of Earthquakes offers an overview of what Davison described as 'the varied phenomena of earthquakes'. Using case studies from around the world, Davison considers the origin of several different classes of earthquakes, including simple, twin and complex. Further attention is devoted to the growth of faults, fore-shocks and after-shocks, sympathetic earthquakes, earthquake sounds and distribution, with supplementary illustrations and maps. Offering contemporary assessments of events ranging from the Mino-Owari earthquake of 1891 to the Californian earthquake of 1906, this volume will appeal to anyone interested in the history and development of seismology in the early part of the twentieth century.

This important volume reviews the status of investigations aimed at deciphering the geologic, biogeographic, and archaeological records for the Quaternary Era--the last million years of geologic time-for the area of continental United States. Over eighty Quaternary scientists have contributed to the fifty-five chapters divided into four main parts. Part 1 treats the areal geology, with emphasis on the stratigraphy of the glaciated areas east of the Rocky Mountains, unglaciated eastern and central United States, and western United States. Part 2 deals with biogeography: phytogeography and palynology, animal geography and evolution. Part 3 deals with archaeology prehistory in the northeastern states, southeastern states, plains, desert west, and Pacific Coast including Alaska. Part 4 covers many diverse Quaternary studies on--the continental shelves, isotope geochemistry, paleopedology, the geochemistry of some lake sediments, paleohydrology, glaciers and climate, volcanic-ash chronology, paleomagnetism, neo-tectonics, dendrochronology, and theoretical paleoclimatology.

The theory of plate tectonics transformed earth science. The hypothesis that the earth's outermost layers consist of mostly rigid plates that move over an inner surface helped describe the growth of new seafloor, confirm continental drift, and explain why earthquakes and volcanoes occur in some places and not others. Lynn R. Sykes played a key role in the birth of plate tectonics, conducting revelatory research on earthquakes. In this book, he gives an invaluable insider's perspective on the theory's development and its implications. Sykes combines lucid explanation of how plate tectonics revolutionized geology with unparalleled personal reflections. He entered the field when it was on the cusp of radical discoveries. Studying the distribution and mechanisms of earthquakes, Sykes pioneered the identification of seismic gaps-regions that have not ruptured in great earthquakes for a long time-and methods to estimate the possibility of quake recurrence. He recounts the various phases of his career, including his antinuclear activism, and the stories of colleagues around the world who took part in changing the paradigm. Sykes delves into the controversies over earthquake prediction and their importance, especially in the wake of the giant 2011 Japanese earthquake and the accompanying Fukushima disaster. He highlights geology's lessons for nuclear safety, explaining why historic earthquake patterns are crucial to understanding the risks to power plants. Plate Tectonics and Great Earthquakes is the story of a scientist witnessing a revolution and playing an essential role in making it.

The interval between the Carboniferous and Jurassic eras is marked by major changes in the structure and character of the Earth and is associated with massive earthquakes, volcanic activity, and large-scale changes of life at the Permian-Triassic and the Triassic-Jurassic boundaries. In this volume, an international assemblage of geologists reveals a wide range of information about these events in the circum-Pacific region, as a conclusion to International Geological Correlation Programme Project 272. They explore the nature of the changes in the Late Paleozoic and Early Mesozoic, and suggest issues for future investigation through the study of paleontology, biostratigraphy, tectonics, magmatic and volcanic development, ore deposition, paleography and climate. As the circum-Pacific region becomes increasingly important for hydrocarbon and mineral exploration, this book will be an invaluable resource for researchers and students in stratigraphy and paleontology.
