(Texas A&M University. Libraries, 1993)The Permian Basin of west Texas and southern New Mexico is located in the foreland of the Marathon-Ouachita orogenic belt. This complex foreland area consists of several sub-basins that are separated by intraforeland ...
-
(Texas A&M University. Libraries, 1971)The Haney Limestone of middle Chesterian age, is a relatively thin, widespread stratigraphic unit that crops out in a continuous belt along the southern and eastern margins of the Illinois basin. It is part of a well defined ...
-
(Texas A&M University. Libraries, 1996)The Permian San Andres Formation of west Texas and New Mexico is a major hydrocarbon reservoir comprised mainly of anhydritic dolostones that reflect a history of cyclic deposition and reservoir diagenesis. San Andres ...
-
(Texas A&M University. Libraries, 1990)Fabrics in fault rocks along the Lewis thrust fault at Marias Pass, northwest Montana, depend on lithology. Fault rocks derived from hanging-wall dolomite are random-fabric cataclasites, whereas fault rocks that include ...
-
(Texas A&M University. Libraries, 1979)A detailed survey of two tracts of houses on sloping terrain underlain by expansible clay-rich soils indicates that expansive soils are especially susceptible to downhill creep. This poses an additional threat on top of ...
-
(Texas A&M University. Libraries, 1994)Groundwaters from 40 municipal and monitoring wells in Texas were collected for the study of water chemistry and microbiology in the deep subsurface. Carbon isotopic compositions (i.e. $deltasp{13}$C) of dissolved inorganic ...
-
(Texas A&M University. Libraries, 1986)Late Pleistocene to Middle Miocene turbidite sands (0 to 900 m depth below seafloor) from Deep Sea Drilling Project (DSDP) Leg 10 Sites 85, 90, and 91 have an average framework, grain composition of 30% quartz, 25% feldspar, ...
-
(Texas A&M University. Libraries, 1992)Variations in mineralogy and composition of late authigenic sulfur-bearing minerals in upper Smackover limestones recorded diagenetic events associated with hydrocarbon migration. This suite of minerals occurs in samples ...
-
(Texas A&M University. Libraries, 1990)To better understand the process of initiation and propagation of thrust faults in layered rock and die role of weak bed-parallel surfaces in the deformation, we mapped wedge faults (WFs) and bed-parallel faults and described ...
-
(Texas A&M University. Libraries, 1971)The Moodys Branch Formation (Eocene) is a rock unit in the Gulf Coastal Plain which exhibits remarkable strike-persistence along 600 miles of outcrop from East Texas to Alabama. The average thickness of this unit is only ...
-
(Texas A&M University. Libraries, 1995)Recent studies confirm that the Meers fault in southwestern Oklahoma moved in "Late Holocene" creating a maximum 5 meter vertical and possibly appreciably more left-lateral strike slip displacements. During this deformation, ...
-
(Texas A&M University. Libraries, 1987)Evidence of organism interactions (predatory and non-predatory) in recent samples from the Texas Gulf Coast and Pliocene - Pleistocene samples from the Humboldt Basin and Kettleman Hills of California were studied in order ...
-
(Texas A&M University. Libraries, 1971)The Whitestone Member of the Walnut Formation is composed of a sequence of lime grainstones, and is surrounded vertically and laterally by units of monotonous lime mudstones. The interrelationships between the lime grainstones ...
-
(Texas A&M University. Libraries, 1993)Eight pollen and spore sequences from the high ash, high sulfur San Miguel lignite deposit indicate a Late Eocene, Jackson age. In general, the sequences follow a pattern, with high Nyssa kruschii and Rhoipites angustus ...
-
(Texas A&M University. Libraries, 1991)Greater than 20,000 small and medium sized dams use excavated emergency spillway channels to handle flood flows. More than 95% of these dams have never experienced a spillway flow. However, because a great number are less ...
-
(Texas A&M University. Libraries, 1988)The Noland Creek-Wayah metamorphic transition, from the staurolite-kyanite zone to the Wayah granulite-facies metamorphic core, occupies the NW flank and core of high-grade metamorphism in the southwestern North Carolina ...
-
(Texas A&M University. Libraries, 1971)The petrology of coarse, moderately sorted to moderately-well sorted, sands was examined from six rivers in the south eastern Piedmont Province. The six rivers were the Altamaha River, the Ogeechee River, the Savannah ...
-
(Texas A&M University. Libraries, 1968)The Yucca Formation of Neocomian to Aptian age extends from the geosynclinal region of the Chihuahua Trough in Mexico, eastward to the Diablo Platform in Trans-Pecos Texas. At Quitman Gap, in the Quitman Mountains, the ...
-
(Texas A&M University. Libraries, 1971)A fundamental understanding of the relation between stress concentrations at grain contacts and microfractures in granular aggregates is obtained through two-dimensional photomechanical model studies and is tested through ...
-
(Texas A&M University. Libraries, 1990)The impact, of a reservoir on downstream channel erosion has received increasing attention since the 1920's. The sediment-free water released from the reservoir could induce severe problems on downstream channel erosion ...
