Micropaleontology of a part of the Lower Cretaceous in Kent Quandrangle, Texas
(Texas Tech University, 1955-05)
Micropaleontologic and lithologic data obtained from several exposures of Finlay, Duck Creek and Fort Worth equivalents are recorded for comparison with similar information from other areas. Biostratigraphic and paleoecologlcal ...
A carbon isotope and trace element analysis of Pennsylvanian rugose corals, North-Central Texas
(Texas Tech University, 1989-12)
Carbon and oxygen isotopes were analyzed to identify the process of algal symbiosis in Pennslyvanian rugose corals from the Graham Formation of north-central Texas. Because original oxygen and carbon isotopic compositions ...
Stratigraphy of the Ordovician Maravillas Formation
(Texas Tech University, 1958-06)
Study of the bryozoan fauna of the Ordovician Maravilllas Formation in trans-Pecos Texas indicates that the major portion of the formation is of Richmondian age. Exact correlation with the type Ordovician section appears ...
A study of the Silurian system and a Silurian reef in West Texas and Southern New Mexico
(Texas Tech University, 1971-05)
Crustal xenoliths from Potrillo Maar: Implications for evolution of continental crust beneath the southern Rio Grande rift
(Texas Tech University, 2003-08)
The mid-crustal xenoliths from Potrillo maar record a petrologic and geochemical history that has until now been unknown from the Potrillo volcanic field. The igneous and meta-igneous xenoliths are samples of one or more ...
A provenance study of the triassic deposits of Northwestern Texas
(Texas Tech University, 1960-05)
Continental deposits of the Upper Triassic Dockum Group are exposed along the eastern escarpment of the Southern High Plains in northwestern Texas. Three formations are present: the Tecovas, the Trujillo, and the Chinle, ...
A paleomagnetic study of some Texas intrusives
Diversity of late Cenozoic gastropods on the Southern High Plains
(Texas Tech University, 1975-05)
Gastropods are often the only fossils found in late Cenozoic sediments on the Southern High Plains. By virtue of their conservatism and low rate of mobility, gastropods should be sensitive indicators of their environment, ...
A gravity and magnetic investigation of the Amarillo uplift
(Texas Tech University, 1969-05)
