-
(2006)Theory from fracture mechanics and thermodynamics coupled with the results of experimental studies provides evidence to suggest that the adsorption of carbon dioxide on coal causes a decrease in the coal strength. Coal ...
-
(2006)The tectonic evolution of the Rhodope massif involves Mid-Cretaceous contractional deformation and protracted Oligocene and Miocene extension. We present structural, kinematic and strain data on the Kesebir-Kardamos dome ...
-
(2006)17 single crystals were identified by electron backscatter diffraction (EBSD) and isolated from coarse massive haemo-ilmenite ore from South Rogaland, Norway. These were studied using the EBSD results, natural remanent ...
-
(2006)To facilitate geological analyses of the Ulleung Basin in the East Sea (Japan Sea) between Korea and Japan, shipborne and satellite altimetry-derived gravity data are combined to derive a regionally coherent anomaly field. ...
-
EVOLUTIONARY GEOMORPHOLOGY: THRESHOLDS AND NONLINEARITY IN LANDFORM RESPONSE TO ENVIRONMENTAL CHANGE (2006)Geomorphic systems are typically nonlinear, owing largely to their threshold-dominated nature (but due to other factors as well). Nonlinear geomorphic systems may exhibit complex behaviors not possible in linear systems, ...
-
(2006)The variation of frequency-dependent seismic wave attenuation with direction (attenuation anisotropy) contains additional information to that contained in velocity anisotropy. In particular, it has the potential to distinguish ...
-
(2006)Themetavolcanic rocks in the Gorzów Wielkopolski area (NWPoland) are andesite-basalts and andesites derived from contaminated within-plate subalkaline basalt melts. K-Ar dating of primary K-feldspar yields an extrusion age ...
-
(2006)Three-dimensional dynamically consistent laboratory models are carried out to model the large-scale mantle circulation induced by subduction of a laterally migrating slab. A laboratory analogue of a slab-upper mantle system ...
-
ALBITE VEIN FORMATION DURING EXHUMATION OF HIGH-PRESSURE TERRANES: A CASE STUDY FROM ALPINE CORSICA (2006)The formation of late-stage veins can yield valuable information about the movement and composition of fluids during uplift and exhumation of high-pressure terranes. Albite veins are especially suited to this purpose because ...
-
(2006)Marine impacts are one category of crater formation in volatile targets. At target water depths exceeding the diameter of the impactor, the zones of vaporization, melting, and excavation of the standard land-target cratering ...
-
(2006)Nested elliptical closures defining "eye-folds" represent classic (y-z) cross sections through highly curvilinear sheath folds generated during intense ductile deformation in metamorphic rocks. Systematic analysis of 1425 ...
-
(2006)Gravel waves have been observed from many modern submarine fans. However, the internal organization and formative processes of gravel waves are still controversial, because features analogous to gravel waves seen on outcrops ...
-
COMPACTION OF QUARTZ SANDS BY PRESSURE SOLUTION USING A COLE-COLE DISTRIBUTION OF RELAXATION TIMES (2006)Stressed water-infiltrated silica rocks may deform by pervasive pressure solution transfer (PPST), which involves dissolution of the grain-to-grain contacts, transport by diffusion of the solute, and precipitation on the ...
-
(2006)Snow entrainment alters the speed and hence the run-out distance of avalanches, yet little is known about this significant process. We studied entrainment in snow avalanches using observations from (1) the Swiss Vallée de ...
-
(2006)We performed a series of triaxial compressive creep experiments at two different water fugacities to investigate the effect of water on the creep strength of a natural clinopyroxenite. Samples were deformed under water-saturated ...
-
(2006)We have recently proposed the revised spherical cap harmonic analysis (R-SCHA) modeling technique. The new mathematical functions represent faithfully the spatial variations of potential fields in a restricted area. In ...
-
(2006)We have constructed a numerical model of basal ice formation for glacier ice in contact with subglacial sediment. The model predicts four different ice facies whose formation is controlled by availability of subglacial ...
-
(2006)Low-frequency volcanic earthquakes are indicators of magma transport and activity within shallow conduit systems. At a number of volcanoes, these events exhibit a high degree of waveform similarity providing a criterion ...
-
(2006)To better understand the tectonic evolution of South China Block (SCB) in response to the India-Asia collision, we present new paleomagnetic results from Late Cretaceous and Paleogene red bed formations of the Hengyang ...
-
(2006)We study seismic velocity and attenuation structures in the top 400 km of the Earth's inner core based on modeling of differential traveltimes, amplitude ratios, and waveforms of the PKiKP-PKlKP phases observed at the ...
