Jon Erickson "Plate Tectonics: Unraveling the Mysteries of the Earth"

Jon Erickson "Plate Tectonics: Unraveling the Mysteries of the Earth" Published by Facts on File
Publication date : May 2001 ISBN : 0816043272 PDF 320 pages English 17 MB
For anyone who is interested in developments in the study of the Earth's structure, Plate Tectonics offers a full understanding of the theory that provides a single guiding principle to the earth's geological history. Beginning with a historical overview of plate tectonic theory in this century, the book describes in clear, non-technical language how plate tectonics work, how it affected evolution and extinction, and what the future holds.
Coverage includes:
- Seafloor Spreading
- Mountain Building
- The Rock Cycle
- Tectonics and the Environment
- Tectonics in Space
- Continental Draft

Developments in Marine Geology, Volume 5: Quaternary Coral Reef Systems (History, development processes and controlling factors)

Developments in Marine Geology, Volume 5: Quaternary Coral Reef Systems (History, development processes and controlling factors)
Publisher: Elsevier Science ISBN: 0444532471 edition 2009 PDF 500 pages 11,9 mb
This book presents both state-of-the art knowledge from Recent coral reefs (1.8 million to a few centuries old) gained since the eighties, and introduces geologists, oceanographers and environmentalists to sedimentological and paleoecological studies of an ecosystem encompassing some of the world's richest biodiversity. Scleractinian reefs first appeared about 300 million years ago. Today coral reef systems provide some of the most sensitive gauges of environmental change, expressing the complex interplay of chemical, physical, geological and biological factors. The topics covered will include the evolutionary history of reef systems and some of the main reef builders since the Cenozoic, the effects of biological and environmental forces on the zonation of reef systems and the distribution of reef organisms and on reef community dynamics through time, changes in the geometry, anatomy and stratigraphy of reef bodies and systems in relation to changes in sea level and tectonics, the distribution patterns of sedimentary (framework or detrital) facies in relation to those of biological communities, the modes and rates of reef accretion (progradation, aggradation versus backstepping; coral growth versus reef growth), the hydrodynamic forces controlling water circulation through reef structures and their relationship to early diagenetic processes, the major diagenetic processes affecting reef bodies through time (replacement and diddolution, dolomitization, phosphatogenesis), and the record of climate change by both individual coral colonies and reef systems over the Quaternary.

Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.

Geologic Analysis of Naturally Fractured Reservoirs

Geologic Analysis of Naturally Fractured ReservoirsGulf Professional
Publishing April 15, 2001 ISBN-10: 0884153177 320 pages PDF 18.67 mb
Geologists, engineers, and petrophysicists concerned with hydrocarbon production from naturally fractured reservoirs will find this book a valuable tool for obtaining pertinent rock data to evaluate reserves and optimize well location and performance. Nelson emphasizes geological, petrophysical, and rock mechanics to complement other studies of the subject that use well logging and classical engineering approaches.

The Neoproterozoic Timanide Orogen Of Eastern Baltica

The Neoproterozoic Timanide Orogen Of Eastern Baltica
Publisher: Geological Society of London ISBN: 1862391726 edition 2006 PDF 255 pages 34,09 mb
The Neoproterozoic Timanide Orogen of eastern Baltica extends from the high Arctic to the southern Ural Mountains and represents significant crustal growth of the northeastern European continental margin in the late Neoproterozoic. This volume, a co-operation between Western European and Russian scientists within the framework of the European Science Foundation's EUROPROBE programme, provides a comprehensive overview of the orogen and represents a new synthesis of Timanian Orogeny. It includes: the pre-Timanian passive margin deposits of the northern and northeastern flank of the East European Craton; the magmatic, metamorphic and structural evolution of the orogen across the Timan Mountain and Pechora Basin regions to the Ural Mountains; the post-Timanian platform successions, important for interpreting the timing of orogeny and the return to an early Palaeozoic passive margin setting; and the extension of the orogen northwards to Novaya Zemlya. Relationships westwards to the Caledonides of Greenland and Scandinavia and eastwards to the Baikalides of Siberia are also treated.

The Search for the Age of the Earth

The Chronologers' Quest: The Search for the Age of the Earth By Patrick Wyse Jackson
Publisher: Cambridge University Press 2006 310 Pages ISBN: 0521813328 PDF 3 MB
The history of geology and how we learned about the age of the Earth is a fascinating subject, but Jackson, a geologist at Trinity College, Dublin, is unable to explain and pass along his enthusiasm. Aficionados might appreciate the tour through attempts to arrive at the planet's age from ancient myths, the Bible, the salinity of the oceans, temperature readings, fossils, geology, biology, radiology and cosmology. Each chapter ends with a "close but no cigar" statement of why a given theory was a good idea at the time. Numerous sections feel rushed—in particular the opening catalogue of creation myths—though when readers finally arrive at the sections on geology and fossils, Jackson injects more detail and, consequently, more interest. But while the preface states that this book is meant for a general as well as scientific audience, too many terms go undefined and too many names are dropped without immediate explanations of who the people were.
