Product Description
The EU funded interdisciplinary Environmental Tectonics research program ENTEC has led to new insights into the strength distribution of Europe's intraplate lithosphere, and its relationship with the localization of intraplate deformation and associated vertical motions. Pronounced lateral variations in Europe's intraplate strength occur, as a result of recent thermal perturbation in the underlying mantle and inherited inhomogeneity in lithospheric structures, as a result of Europe's polyphase pre-Quaternary evolution.

Results are presented from quantitative subsidence analysis studies, and constraints by geothermochronology, pointing to pronounced acceleration in differential vertical motions and associated topography development in intraplate Europe. These results demonstrate the vulnerability of Europe's lithosphere to neotectonic activity documented by detailed studies in the three natural laboratories of the ENTEC program: (1) the Lower Rhine Graben (LRG), (2) the Upper Rhine Graben (URG), and (3) the Vienna Basin (VB). ...

Description:
Reservoirs associated with salt diapirs that are circular or elliptical in plan view can be segmented by radial faults, concentric faults, both or neither. Explanations for this variation are offered based on integration of fault kinematics, published studies and seismic examples. Strata around diapirs can be divided into three structural domains with characteristic fault styles. (1) Roof zone between the present day depositional surface and crest of a buried, inactive diapir. This zone is characterised by doming, radial faults and occasionally, conic graben. Doming is usually caused by differential compaction and increases with depth. (2) A steeply-dipping sheath of strata surrounds the diapir out to a distance of less than one diapir radius, recording near-surface diapir growth in poorly-lithified sediments. These contain early gravity slumps and late concentric extensional faults. Regional layer-bound polygonal fault systems form radial faults within approximately one diapir radius-the only significant radial faulting mechanism below the roof zone. (3) Diapir root zone of strata whose structural architecture records the diapirs' initiating mechanism, typically rim synclines or graben that detach on the salt source layer. Concentric faults at radial distances of a kilometre or more have been found only in root zone rim synclines and sheared sheath strata. These models and observations can assist seismic interpretation and structural model building in areas of poor geophysical imaging, for instance below overhanging salt. ... Read more

Purchase includes a free trial membership in the publisher's book club where you can select from more than a million books without charge. Excerpt: The San Andreas Fault is a continental transform fault that runs a length of roughly 810 miles (1,300 km) through California in the United States. The fault's motion is right-lateral strike-slip (horizontal motion). It forms the tectonic boundary between the Pacific Plate and the North American Plate. The fault was first identified in Northern California by UC Berkeley geology professor Andrew Lawson in 1895 and named by him after a small lake which lies in a linear valley formed by the fault just south of San Francisco, the Laguna de San Andreas. After the 1906 San Francisco Earthquake, Lawson also discovered that the San Andreas Fault stretched southward into Southern California. Large-scale (hundreds of miles) lateral movement along the fault was first proposed in a 1953 paper by geologists Mason Hill and Thomas Dibblee. Located at the Highway 138 and Interstate 15 junction, the Mormon Rocks are visual evidence of the San Andreas fault lying beneath the California surface. Vasquez Rocks in Agua Dulce, California are evidence of the San Andreas Faultline and part of the 2,650 mile Pacific Crest Trail. Map of the San Andreas Fault, showing relative motion. Note that both sides are moving to the northwest, but at different rates.The San Andreas Fault can be divided into three segments. The southern segment (known as the Mojave segment) begins near the Salton Sea at the northern terminus of the East Pacific Rise and runs northward before it begins a slow bend to the west where it meets the San Bernardino Mountains. It runs along the southern base of the San Bernardino Mountains, crosses through the Cajon Pass...More: http://booksllc.net/?id=64460 ... Read more
