(Texas A&M University. Libraries, 1989)Three hundred and twenty-one (321) samples from 15 type and reference sections of strata of the Eagle Ford, Austin, and lower Taylor (Cenomanian to early Campanian) in central, north-central, and northern Texas were examined ...
-
(Texas A&M University. Libraries, 1992)Time-structure maps of the basement in the study area show two different sets of faults. These faults trend NNW-SSE in the northern and middle areas and NE-SW in the southern area. Strain ellipse indicates that the fault ...
-
(Texas A&M University. Libraries, 1989)Biostratigraphy, diversity, and oxygen and carbon isotopes are determined for calcareous nannoplankton from four sections of Cretaceous-Tertiary boundary interval sediments on Walvis Ridge in the South Atlantic (DSDP Sites ...
-
(Texas A&M University. Libraries, )Integration of biostratigraphy and sedimentology of Deep Sea Drilling Project (DSDP) drill core samples from the western North Atlantic Ocean resulted in a reconstruction of the Cretaceous geologic history of this ocean ...
-
Depositional environment of the Sam Miguel lignite deposit in Atascosa and McMullen Counties, Texas (Texas A&M University. Libraries, 1985)Previous investigators interpreted the San Miguel lignite to be the result of swamps and/or marshes that existed on the landward side of a lagoon. The partings were "fire-splay" deposits that originated from coastal streams ...
-
(Texas A&M University. Libraries, 1981)The Oligocene/Miocene Catahoula Formation of the Texas coastal plain is a fluvial and lacustrine volcaniclastic unit composed of "normal" fluvial material mixed with distal rhyolitic air-fall ash and, in the lower coastal ...
-
(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, 1977)Integrated high resolution seismic and core data from the Texas outer continental shelf and upper continental slope were used to reconstruct the late Pleistocene geologic history of the area. Seismically aided correlation ...
-
(Texas A&M University. Libraries, 1994)The early geologic history of the DeSoto Canyon Salt Basin (DSCSB) in the northeastern Gulf of Mexico can be explained by Mesozoic extensional processes associated with a rifted, passively subsiding continental margin. ...
-
(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, 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, )Mississippi delta sediments sampled from 141 boreholes drilled offshore of southeastern Louisiana were investigated in order to develop a method of predicting their geotechnical properties. Regression analysis and correlation ...
-
(Texas A&M University. Libraries, 1984)The Late Pleistocene sediments in the deep basin of the Gulf of Mexico are marked by several episodes of the preservation of aragonitic pteropods. Pteropods are not preserved on the sea floor of the abyssal Gulf today nor ...
-
(Texas A&M University. Libraries, 1992)The regional distribution of salt in the northwestern Gulf of Mexico reflects a complex interplay between tectonic basin architecture and subsequent salt kinematics. Persistent northwest-southeast structural trends across ...
-
(Texas A&M University. Libraries, 1984)Examination of extensive multichannel and single-channel data across the Mississippi Fan, Gulf of Mexico reveals that at least eight seismic sequences comprise the Pliocene/Pleistocene section (sequences I-VIII, oldest to ...
-
(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, 1976)Regional investigation of late Quaternary deposits on the outer Louisiana shelf indicated two principle structural provinces: (1) a western province between West Cameron and Ship Shoal Areas which is highly faulted and ...
