(2001)The bombardment of the lunar surface by cosmic rays produces secondary neutrons, some of which are thermalized by the lunar soil and then interact strongly with the isotopes of Cd, Gd and Sm which have high neutron capture ...
-
(1997)A new method for measuring volumes of fluids in a piston cylinder apparatus has been tested and applied to measuring the molar volume of H2O VH2O from 8.5 to 20 kbar and 800° to 1000°C. A thick-walled nickel capsule partially ...

MEASURING QUARTZ SOLUBILITY BY IN SITU WEIGHT-LOSS DETERMINATION USING A HYDROTHERMAL DIAMOND CELL (2004)The solubility of quartz was determined using a hydrothermal diamond anvil cell (HDAC) within the temperature and pressure ranges of 126 to 490°C and up to 8.9 kbar, respectively. A novel approach has been used to measure ...
-
(2002)For the coal industry to remain competitive into the 21st century, particularly if coal prices remain low, it is incumbent upon the industry to understand their products and use this knowledge to improve the efficiency, ...
-
(2001)Elastic deformations of host rocks during the emplacement within the Earth's crust of magmatic intrusions, such as laccoliths and lopoliths, are analyzed. The present analysis is built upon semianalytic elastic solutions ...
-
(2002)A mechanical model of forced-folding, comprised of an anisotropic cover overlying displaced, rigid basement blocks, is used to investigate the influence of various parameters on theoretical fold form: shape and dip of ...
-
(1998)Mechanical and phase equilibria in inclusion-host systems are investigated in this paper. An inclusion-host system that is initially under lithostatic pressure and in mechanical and phase equilibria may undergo ...
-
(1997)Different assumptions for the thermo-mechanical properties of the lithosphere strongly affect predictions inferred from quantitative sedimentary basin modeling. Examples from various basins, selected as natural laboratories, ...
-
(2004)Deformation experiments have been performed on polycrystalline stishovite at 14 GPa and 1300°C in a multi-anvil press. The easy slip systems have been determined by Transmission Electron Microscopy. We found [001]{100} and ...
-
(2003)Faults propagating through the Earth generate a wave of deformation ahead of their tip lines. We have modeled this process to understand the relationship between fold geometry and fault propagation. Using finite element ...
-
(2002)Previous workers have formulated velocity descriptions of the trishear kinematic model of fault propagation-folds, which are inherently non-unique. We present two complete mechanical models of fault-related folding and ...
-
(2001)Approximate relations are developed to determine the steady stresses and displacements that may develop in unlined and lined drifts heated above ambient, as representative of conditions in a nuclear waste repository. For ...
-
(2002)Modeling the process of bubble growth in sediments requires an understanding of the physics that controls bubble shape and the interaction of the growing bubble with the sediment. To acquire this understanding we have ...
-
(2004)In thrust belts, fold–fault terminations are common features of the structural architecture and can pose complicated problems to unravel, in particular when two or more terminations are in close proximity. Such terminations ...
-
(1988)We consider the movement of free blocks in a rock body undergoing deformation. To identify the principal qualitative phenomena accompanying this process, a simple model is used. A cubic block interacts with neighboring ...
-
(2004)A 3-D model of shear fracture in an elastic half-space provides insight into the initiation of sliding along weak pre-existing surfaces in rock or consolidated sediments. An elastic model is justified physically if regions ...
-
(1988)In order to analyze the history of the continental lithosphere, identify its current movements, and predict earthquakes, the author starts from the view that it consists of relatively small blocks (with areas of 102 to 104 ...
-
(1990)In large-scale analyses of geologic maps, many investigators have identified not only linear anomalies, but both annular and square-block anomalies. The conclusion that annular and other closed structures of various orders ...
-
(1990)The block model enables us to identify several characteristic features of the deformation of the crustal medium that are typical of multicomponent mechanical systems. A nontrivial property of block structure is its ability ...
-
(2002)Although complex rheological models have been used to study the evolution of orogenic wedges, many features of simple models remain to be fully explained. Here, we analyze the plane strain evolution of model orogenic wedges ...
