(2006)New results on the pressure-temperature-time evolution, deduced from conventional geothermobarometry and in situ U-Th-total Pb dating of monazite, are presented for the Bemarivo Belt in northern Madagascar. The belt is ...
-
(2006)Recent research has established that the dominant P-wave attenuation mechanism in reservoir rocks at seismic frequencies is because of wave-induced fluid flow (mesoscopic loss). The P-wave induces a fluid-pressure difference ...
-
(2006)To explore the validity and limitations of the theoretical model of wave propagation in porous rocks with periodic distribution of planar fractures, we perform numerical simulation using a poroelastic reflectivity algorithm. ...
-
(2006)The Legs Lake shear zone is a crustal-scale thrust fault system in the western Canadian Shield that juxtaposes high-pressure (1.0 + GPa) granulite facies rocks against shallow crustal (< 0.5 GPa) amphibolite facies rocks. ...
-
(2006)The Qinling orogen of central China occupies a key position in East Asia, and is of fundamental importance in unraveling its tectonic evolution. Devonian sedimentary basins are located between the North Qinling arc and the ...
-
(2006)Spontaneous potentials associated with volcanic activity are often interpreted by means of the electrokinetic potential, which is usually positive in the flow direction (i.e. Zeta potential of the rock is negative). The ...
-
(2006)The Jericho kimberlites are part of a small Jurassic kimberlite cluster in the northern Slave craton, Canada. A variety of dating techniques were applied to constrain the nature and age of two Jericho kimberlites, JD-1 ...
-
(2006)Spot analysis techniques have been used to unravel crystallization processes in a Palaeogene coarse-grained, olivine-bearing, gabbronoritic plug from East Greenland. Whole-rock analyses of the gabbronorite and its chilled ...
-
(2006)The osmium isotope ratios and platinum-group element (PGE) concentrations of impact-melt rocks in the Chesapeake Bay impact structure were determined. The impact-melt rocks come from the cored part of a lower-crater section ...
-
CLAY MINERALS RELATED TO THE HYDROTHERMAL ACTIVITY OF THE BOUILLANTE GEOTHERMAL FIELD (GUADELOUPE) (2006)The geothermal field of Bouillante (Guadeloupe, FWI) is a high-enthalpy hydrothermal system emplaced in submarine volcanoclastic formations (hyaloclastites, scarce lava flows) and subaerial formations (andesitic lava flows, ...
-
(2006)We study the crustal structure of eastern Marmara region by applying the receiver function method to the data obtained from the 11 broad-band stations that have been in operation since the 1999 İzmit earthquake. The stacked ...
-
(2006)Connectivity of high permeability paths is recognized as important but has not been properly quantified in the groundwater literature. In fact, it has been shown that the concept is process dependent and difficult to define ...
-
(2006)This study reports on the geometric and structural characteristics of the North Anatolian Fault Zone in the southwest Marmara region. The geometric and kinematic features of the faults in the region are described, based ...
-
(2006)The Musgrave Block in central southern Australia separates the dominantly Paleoproterozoic North Australian Craton from the Late Archean to early Mesoproterozoic Gawler Craton in southern Australia. Geochemical and Nd ...
-
(2006)The rifting of continents and eventual formation of ocean basins is a fundamental component of Plate tectonics, yet the mechanism for break-up is poorly understood. The East African Rift System (EARS) is an ideal place to ...
-
(2006)We analyzed mantle anisotropy along the Red Sea and across the Arabian Peninsula using shear-wave splitting recorded by stations from three different seismic networks - the largest, most widely distributed array of stations ...
-
(2006)Although the East African Rift (EAR) System is often cited as the archetype for models of continental rifting and break-up, its present-day kinematics remains poorly constrained. We show that the currently available GPS ...
-
(2006)Occurrence of phosphate cemented-sandstone concretions in alluvial sand containing archaeological layers implies that they have formed during the last 2000 years. Morphology and petrography of the concretions indicates a ...
-
(2006)In cold regions the thermal regime is strongly affected by freezing or melting processes, consuming or releasing large amounts of latent heat. This changes enthalpy by orders of magnitude. We present a numerical approach ...
-
(2006)Interpretation of the aeromagnetic survey of northeastern Cuba at scale 150 000 is presented. Mainly ophiolitic rocks are characterized by a high magnetic response. The aeromagnetic data was reduced to the pole and the ...
