We are poised to embark on a new era of discovery in the study of geomorphology. The discipline has a long and illustrious history, but in recent years an entirely new way of studying landscapes and seascapes has been developed. It involves the use of 3D seismic data. Just as CAT scans allow medical staff to view our anatomy in 3D, seismic data now allows Earth scientists to do what the early geomorphologists could only dream of - view tens and hundreds of square kilometres of the Earth's subsurface in 3D and therefore see for the first time how landscapes have evolved through time. This volume demonstrates how Earth scientists are starting to use this relatively new tool to study the dynamic evolution of a range of sedimentary environments.

R. M. Teeuw - Mapping Hazardous Terrain using Remote Sensing
Publisher: Geological Society of London | 2007-08-15 | ISBN: 1862392293 | PDF | 357 pages | 12.00 MB


The dangers that we face from geohazards appear to be getting worse, especially with the impact of increasing population and global climate change. This collection of papers illustrates how remote sensing technologies - measuring, mapping and monitoring the Earths surface from aircraft or satellites - can help us to rapidly detect and better manage geohazards. The hazardous terrains examined include areas of landslides, flooding, erosion, contaminated land, shrink-swell clays, subsidence, seismic activity and volcanic landforms. Key aspects of remote sensing are introduced, making this a book that can easily be read by those who are unfamiliar with remote sensing. The featured remote sensing systems include aerial photography and photogrammetry, thermal scanning, hyperspectral sensors, airborne laser altimetry (LiDAR), radar interferometry and multispectral satellites (Landsat, ASTER). Related technologies and methodologies, such as the processing of Digital Elevation Models and data analysis using Geographical Information Systems, are also discussed.

H. Lewis, G. D. Couples - The Relationship between Damage and Localization

H. Lewis, G. D. Couples - The Relationship between Damage and Localization
Publisher: Geological Society of London | 2007-11-15 | ISBN: 1862392366 | PDF | 254 pages | 14.50 MB


The many kinds of porous geomaterials (rocks, soils, concrete, etc.) exhibit a range of responses when undergoing inelastic deformation. In doing so they commonly develop well-ordered fabric elements, forming fractures, shear bands and compaction bands, so creating the planar fabrics that are regarded as localization. Because these induced localization fabrics alter the bulk material properties (such as permeability, acoustic characteristics and strength), it is important to understand how and why localization occurs, and how it relates to its setting. The concept of damage (in several uses) describes both the precursor to localization and the context within which it occurs. A key theme is that geomaterials display a strong material evolution during deformation, revealing a close linkage between the damage and localization processes.
This volume assembles perspectives from a number of disciplines, including soil mechanics, rock mechanics, structural geology, seismic anisotropy and reservoir engineering. The papers range from theoretical to observational, and include contributions showing how the deformed geomaterials emergent bulk characteristics, like permeability and seismic anisotropy, can be predicted. This book will be of interest to a wide range of geoscientists and engineers who deal with characterization of deformed materials.

Iain S. Stewart, Claudio Vita-Finzi - Coastal Tectonics

Iain S. Stewart, Claudio Vita-Finzi - Coastal Tectonics
Publisher: Geological Society of London | 1999-02-01 | ISBN: 186239024X | PDF | 378 pages | 50.83 MB


Describes the application of high-resolution coastal records to developing and testing tectonic models. The case studies are at scales ranging from global to local and deal with glacioisostasy, relative sea-level change and seismic and aseismic crustal deformation at a variety of timescales. An international perspective presenting a host of field data from contrasting parts of the world as well as novel modelling and analytical approaches. It is the only book that considers the topic with such scope. Readership: Tectonic geologists, Quaternary scientists, professionals involved in seismic hazard or coastal development/protection.

M. Wilson - Permo-carboniferous Magmatism And Rifting in Europe

M. Wilson - Permo-carboniferous Magmatism And Rifting in Europe
Publisher: Geological Society of London | 2004-01-01 | ISBN: 1862391521 | PDF | 498 pages | 101.88 MB


Widespread extension occurred within the Variscan orogen and its northern foreland during Late Carboniferous to Early Permian times. This was associated with magmatism and with a fundamental change, at the Westphalian-Stephanian boundary, in the regional stress field, coincident with the termination of orogenic activity and onset of dextral translation between North Africa and Europe. Rifting propagated across basement terranes with different ages and thermal histories. Most of the rift basins developed on relatively thin lithosphere; however, the highly magmatic Oslo Graben initiated within the edge of a craton. Early Stephanian regional uplift is contemporaneous with the onset of magmatism, inviting speculation that it might have been induced by a thermal anomaly within the upper mantle. The contributions to this volume suggest that the geodynamic setting in which magmatism occurred was complex, involving wrench tectonics, slab detachment, and delamination or thermal erosion of the base of the lithosphere.

D. McIlroy - The Application of Ichnology to Palaeoenvironmental And Stratigraphic Analysis

D. McIlroy - The Application of Ichnology to Palaeoenvironmental And Stratigraphic Analysis
Publisher: Geological Society of London | 2004-01-01 | ISBN: 1862391548 | PDF | 490 pages | 53.73 MB


It has been increasingly realized by sedimentologists in the petroleum industry and academia that integration of ichnological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. This volume aims to provide an analytical review of the ichnology of all major depositional environments and the use of ichnology in biostratigraphic and sequence stratigraphic analysis, as well as highly refined palaeoenvironmental studies. The remit of the book is achieved through a combination of review articles and novel research papers that outline methodologies and protocols for improving our understanding of ancient palaeoenvironments. Trace fossils from microscopic borings to dinosaur footprints are considered.
The comprehensive coverage of ancient depositional environments means that the book will be of use as a course text for undergraduates as well as an invaluable reference text for all interested in ichnology whether they are ichnologists, sedimentologists or petroleum geologists by trade.
