Stable isotope geochemistry of caliche in the Blackwater Draw Formation, southern High Plains, Texas
(Texas Tech University, 2001-12)
Stable carbon and oxygen isotopic ratios were measured for soil carbonate and organic matter from three successive caliche horizons in the type section of the Blackwater Draw Formation in northern Lubbock County, Texas. ...
High-temperature deformation in the Josephine Peridotite: linkage between crustal and mantle spreading structure in a supra-subduction zone ophiolite
(Texas Tech University, 2003-08)
The Josephine peridotite is a tectonized harzburgite that represents the upper mantle beneath a paleo-spreading ridge (Dick, 1976; Loney and Himmelberg,1976; Dick and Sinton, 1979). Structures in the peridotite such as ...

Identification of Pore Structure and Clay Content from Seismic Data within an Argillaceous Sandstone Reservoir
Sandstone facies are good reservoirs for the accumulation of hydrocarbons in conventional exploration due to high porosity and permeability. Grain size variations within a sandstone reservoir can range from pebbles to ...
Sediments and Topography of the Western Gulf of Mexico
(Texas Tech University, 1967-08)
Relative frequencies of temperature sensitive planktonic foraminifera, in sediment cores raised from the continental slope and Sigsbee Abyssal Plain in the Gulf of Mexico, indicate alternating periods of warm and cold ...

Structural and metamorphic history of precambrian rocks, Upper Gallinas Creek area, San Miguel County, New Mexico
(Texas Tech University, 1978-05)
Precambrian rocks in the upper Gallinas Creek area of the southern Sangre de Cristo Mountains, New Mexico, display two metamorphic and two deformational events and at least two episodes of igneous intrusion. The first ...
Paleontology and geology of an upper Pennsylvanian tetrapod locality from the Ada Formation: Seminole County, Oklahoma
(Texas Tech University, 1999-12)
The paleontology, taphonomy, stratigraphy, depositional setting, and paleozoogeographic significance of an Upper Pennsylvanian tetrapod-bearing fossil locality is presented. The site, OMNH Locality V1005, is located within ...
