Available in PDF, EPUB and Kindle. Book excerpt: La 4e de couv. indique : "The concept of plate tectonics is relatively new - it was only in the 1960s that the idea that continents drifted with respect to one another came to be accepted. Plate tectonics now forms one of geology's basic principles and explains much of the large-scale structure and phenomena we see on Earth today. In this Very Short Introduction Peter Molnar explores the impact that plate tectonics has had on our understanding of Earth : how the ocean floor forms, widens, and disappears ; why earthquakes and volcanoes are found in distinct zones ; and how the great mountain ranges of the world were built. As the Himalaya continues to grow, the Atlantic widens, and new ocean floor is forming, the mechanisms of plate tectonics continue to alter the surface of our planet."

Download or read book Geomagnetic Observations and Models written by M. Mandea and published by Springer Science & Business Media. This book was released on 2010-12-10 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides comprehensive and authoritative coverage of all the main areas linked to geomagnetic field observation, from instrumentation to methodology, on ground or near-Earth. Efforts are also focused on a 21st century e-Science approach to open access to all geomagnetic data, but also to the data preservation, data discovery, data rescue, and capacity building. Finally, modeling magnetic fields with different internal origins, with their variation in space and time, is an attempt to draw together into one place the traditional work in producing models as IGRF or describing the magnetic anomalies.

Download or read book Tectonics written by Eldridge M. Moores and published by Waveland Press. This book was released on 2014-07-23 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deformation of the Earth’s crust happens at a multitude of scales, ranging from submicroscopic to planetary. Tectonics explores structures and processes from regional to global, differentiating itself from the material covered in most structural geology textbooks. Moores and Twiss emphasize basic principles and methodologies of tectonics, embracing the time-honored perspective of using present processes to understand the past. Comprehensive in scope and detail, coverage includes the effects of plate motions and reconstructions and the resultant structures associated with active rift, transform, and subduction boundaries as well as triple junctions and collision zones; deformations of both the ocean basins and the continents; and orogenic belts. Moores and Twiss present tectonics as an open-ended field of study in which assumptions can be challenged and interpretations changed. The authors emphasize the use of models as a means of understanding observations and putting them in context to maintain a distinction between what we know from observing the Earth and what we infer from interpretation.

Download or read book Seismic Detection and Discrimination Using Ocean bottom Seismographs written by LeRoy M. Dorman and published by . This book was released on 1980 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research progress on seismic detection and discrimination using ocean-bottom seismographs (OBS's) is outlined. During this first year of DARPA contract work, our investigations have been focused primarily on using existing OBS data to address the problem of sea-floor seismic noise and to constrain models of the near-bottom seismic environment. We have completed noise studies at six of our previously occupied OBS sites. The noise levels of typical amplitude spectra roll off rapidly out to 2-4 Hz and much less rapidly beyond 4 Hz. At frequencies above 4 Hz, the noise levels are low, typically a few nanometers/Hz1/2 or less and comparable to good land-based stations. Several correlations between noise levels and other parameters, such as sediment thickness, distance from the continental margin and sea state, are discussed and used to constrain possible noise mechanisms. We hypothesize that the dominant mechanism of high-frequency (>2 Hz) noise generation at most of the sites examined thus far is of local oceanographic origin, exciting acoustic modes in the water column which couple to Stoneley modes at the sediment-water interface and waveguide modes within the sediment column. This hypothesis is supported by the analysis of noise data from two OBS arrays, which shows that the noise coherence is very low for pairs of sensors separated by as little as 200 m. We also outline some of the conclusions relevant to the seismic noise problem deduced by us from the data collected during the Lopez Island intercalibration experiment.

Download or read book InSAR Imaging of Aleutian Volcanoes written by Zhong Lu and published by Springer Science & Business Media. This book was released on 2014-03-31 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interferometric synthetic aperture radar (InSAR) is a relatively new remote sensing tool that is capable of measuring ground-surface deformation with centimeter-to-subcentimeter precision at a spatial resolution of tens of meters over an area of hundreds to thousands of square kilometers. With its global coverage and all-weather imaging capability, InSAR has become an increasingly important technique for studying volcanoes in remote regions such as the Aleutian Islands. The spatial distribution of surface deformation data derived from InSAR images enables the construction of detailed mechanical models to enhance the study of magmatic processes. InSAR Imaging of Aleutian Volcanoes: • Provides a theoretical framework for InSAR observations and capabilities • Discusses state-of-the-art InSAR analysis techniques • Describes the structure, eruptive history, and magma composition of volcanoes along the entire Aleutian arc • Presents conceptual models for the magma plumbing systems of Aleutian volcanoes based on InSAR results combined with geophysical, geological and geochemical observations. • Synthesizes observations of deformation along the Aleutian arc and compares those results to other active arcs around the world. • Is illustrated throughout with high-resolution color satellite radar images

Available in PDF, EPUB and Kindle. Book excerpt: This memoir summarizes the current knowledge of New Caledonia’s geology, geodynamic evolution, and mineral resources, based on published and unpublished information. It comprises 10 research papers, each addressing a particular geological assemblage or topic. After an introductory chapter, and a review of the published geodynamic models of evolution of the SW Pacific, chapters 3 to 5 focus on the main geological assemblages of Grande Terre: the Pre-Late Cretaceous basement terranes, the Late Cretaceous to Eocene cover, and the Eocene subduction-obduction complex, one of the largest and best-preserved in the world. Chapter 6 is devoted to the Loyalty Islands and Ridge. Chapter 7 deals with the mostly terrestrial post-obduction units including regolith. Chapter 8 deals with palaeobiogeography and discuss plausible scenarios of biotic evolution. Chapters 9 and 10 provide an comprehensive review of New Caledonia’s mineral resources. The volume will interest stratigraphers, sedimentologists, marine geologists, palaeontologists, palaeogeographers, igneous and metamorphic petrologists, geochemists, geochronologists, and specialists in tectonics, geodynamic evolution, regolith, ophiolites, and economic geology.
