(Texas A&M University. Libraries, 1977)Although a qualitative understanding of the fracture of rocks has been acquired, quantitative models are still inadequate. The construction of a predictive model of the brittle deformation of crystalline rocks requires ...
-
(Texas A&M University. Libraries, 1985)The microstructures and rheology of quartz gouge (grain size < 130 μm), deformed under dry and hydrothermal conditions in experimental shear zones, are described. Layers ([sine wave] 0.3 μm) of quartz powder are sheared ...
-
(Texas A&M University. Libraries, 1979)During Laramide tectonism, the aeolian Wingate Sandstone was forced folded along the northeast of the Uncompahgre Plateau above faults within the underlying crystalline basement. The internal deformation of the Wingate ...
-
(Texas A&M University. Libraries, 1981)This dissertation is concerned with understanding frictional deformation mechanisms in the context of earthquake prediction. Using experimental rock deformation techniques, attempts are made to simulate realistic hypocentral ...
-
(Texas A&M University. Libraries, 1991)To gain insight into the rheology of selected feldspar-bearing rocks from the continental lower crust (CLC), three compositionally-diverse assemblages from exposed PreCambrian lower crustal terrains and a microgabbro have ...
-
(Texas A&M University. Libraries, 1984)This work addresses semibrittle deformation of rock, characteristic of high temperature and low pressure environments. To enhance the understanding of this multimechanistic deformation regime results are presented on: (1) ...
-
(Texas A&M University. Libraries, 1990)The cause of the Cretaceous-Tertiary (K/T) transition remains one of the most controversial scientific topics in the geosciences. Paleontologic, mineralogic, geochemical, and geophysical evidence associated with the K/T ...
-
(Texas A&M University. Libraries, 1978)The presently available and widely used model describing the style of deformation of rocks in ramp regions of overthrust faults is that proposed by Rich (1934) for the Pine Mountain overthrust in the southern Appalachian ...
-
(Texas A&M University. Libraries, 1988)The change with depth in the Earth's crust from cataclastic faulting to dislocation-dominated (intracrystalline-plastic) ductile flow is correlative with many geological and geophysical phenomena. An analogous transition ...
-
(Texas A&M University. Libraries, 1980)Cylindrical specimens of several sandstones, carbonates, and quartz-rich siltstones, exhibiting a wide range of porosities, are deformed in a computer-controlled hydraulic loading apparatus. They are loaded with axial ...
