(Texas A&M University. Libraries, 1976)The growth of slip along a bend in a fault is analyzed using complex variable techniques of plane elasticity and conformal mapping of the fault-plane geometry. The analytical model uses fault-displacements of the form, [(s ...
-
(Texas A&M University. Libraries, 1973)The Delaware Mountain Group in the Delaware Basin of west Texas and southeast New Mexico consists of a thick sequence of late Permian clastics deposited in a deep-water, marine setting. The basinal facies and depositional ...
-
(Texas A&M University. Libraries, 1993)Detailed mapping of central eastern Texas using deep well log and seismic data indicate that the region is underlain by a thickened sedimentary section, referred to here as the Brazos basin. Recognition of this basin ...
-
(Texas A&M University. Libraries, 1992)The stoichiometric Henry's law constant and dissociation constants for the carbonic acid system were experimentally determined in various aqueous solutions from 0 to 90°C to high ionic strengths by the solubility method ...
-
(Texas A&M University. Libraries, 1991)The Mississippian Mission Canyon Formation (Osagean to lower Meramecian) occurs in central and southwestern Montana as a thick sequence of interbedded shallow water limestones and dolostones. Most of the dolomite in the ...
-
(Texas A&M University. Libraries, 1978)The Upper Miocene Stevens Sandstone of the San Joaquin Valley, California was deposited in an active forearc basin. Compositionally the Stevens is characterized by a high content of feldspar and volcanic rock fragments. ...
-
(Texas A&M University. Libraries, 1970)Laboratory data suggest that shallowly buried granitic basement rocks behave in a brittle fashion. Field evidence confirms this suggestion. However, laboratory results suggest that the deformations of sedimentary rocks ...
-
(Texas A&M University. Libraries, 1976)Room-temperature, compression tests at strain rates from 10⁻² to 10 s⁻¹ are run on Charcoal Granodiorite to 0.45 GPa confining pressure and on Berea Sandstone and Indiana Limestone to 0.25 GPa confining pressure. For each ...
-
(Texas A&M University. Libraries, 1977)The effects of fault gouge on the sliding behavior of rocks are studied experimentally to gain a better understanding of the mechanism of shallow focus earthquakes along pre-existing natural faults. Nearly 200 specimens ...
-
(Texas A&M University. Libraries, 1973)The fundamental cause of slope instability in the Waco area is the response of the local strata to natural and man-made disturbances. Most slope failures occur during or shortly after periods of heavy rainfall, where natural ...
-
(Texas A&M University. Libraries, 1979)Laboratory hydraulic facture experiments are conducted on monolithologic and dilithologic layered rock specimens as a function of interfacial normal stress to determine the relative influence of the interfacial shear ...
-
(Texas A&M University. Libraries, 1965)The West White Lake, South Bosco-Duson-Ridge, and Abbeville-Perry-South Perry structures are located in the Oligocene and Miocene oil- and gas-producing trends of south-central Coastal Louisiana. Strata encountered by ...
-
(Texas A&M University. Libraries, 1993)The Llano Uplift in Central Texas is a Grenville-aged metamorphic terrane consisting predominantly of amphibolite facies mineral assemblages. Temperatures for the amphibolite facies metamorphism are constrained at 475-650°C. ...
-
(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, 1993)The cyclic pattern of deposition in the Horquilla Limestone of southeastern Arizona resulted from glacio-eustatic sea-level fluctuations with periodicities within the Milankovitch band. The depositional surface fluctuated ...
-
(Texas A&M University. Libraries, 1964)Ten iron-silicate mineral samples from the Viesca Member of the Weches Formation, the Therrill Member of the Weches Formation, the Stone City Member of the Crockett Formation, and the Landrum Member of the Crockett Formation ...
-
(Texas A&M University. Libraries, 1986)The concept of forced folding (Stearns, 1971,1978) forms the basis for the research reported here on Rattlesnake Mountain Anticline. Field observations address fold formation with respect to: causative basement blocks, the ...
-
(Texas A&M University. Libraries, 1992)Map-view curves in thrust-fault traces are common in fold-and-thrust belts. Frontal-transverse-frontal ramp geometries are typically the reason. However, not all curves in thrust-fault traces can be related directly to ...
-
(Texas A&M University. Libraries, 1995)Specially processed Landsat Thematic Mapper (TM) data are calibrated to the spectral characteristics of the greater Pearsall Oilfield deduced from geochemical and laboratory spectral analyses of soil samples to develop a ...
-
(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 ...
