Hofig, Daianne F (2021-03-22)Lacustrine varved sediments are high-resolution paleoenvironmental archives, in which their layers function as temporal markers of seasonality. The temporal framework of such records is required to improve benchmark climate ...
-
Roberts, Melissa Delane (Texas A&M University, 2005-08-29)Given that the mobility, bioavailability, and toxicity of arsenate in natural systems is often controlled by the strong binding capacity of iron oxyhydroxides, the objective of this study was to document the interactions ...
-
Banerjee, Sikhar (2012-02-14)The purpose of this study is to identify and analyze the geochemical facies of the Hushpuckney Shale using XRF scanning data and the bioturbation indices, which will contribute to a better understanding of the biogeochemical ...
-
Gledhill, Dwight Kuehl (Texas A&M University, 2006-08-16)Sedimentary basins can contain close to 20% by volume pore fluids that are commonly classified as brines. These fluids can become undersaturated with respect to calcite as a result of processes such as migration, dispersive ...
-
Elston, Kristen Eileen (Texas A&M University, 2007-04-25)Sediments from two cores, JPC31 and JPC46, were analyzed to better understand the relationship between climate and sediment deposition on the continental slope of the northwestern Gulf of Mexico. These two cores were ...
-
Aydin, Tuba (2013-06-17)This study aims to document the dinoflagellate cyst biostratigraphy and paleoenvironmental record of the Maastrichtian Neylandville and Corsicana Formations and the lower part of the Danian Kincaid Formation from the Brazos ...
-
Moustafa, Mohamed Salem Hamadi (2015-05-13)This study presents the depositional facies, sequence stratigraphy, chemostratigraphy and diagenetic evolution of the Middle-Late Triassic Al Aziziyah Formation, Jifarah Basin northwest Libya. Eight measured sections were ...
-
Fagundes De Rezende, Marcelo (2015-06-18)Microbialite carbonate deposits are highly influenced by environmental settings, resulting in a large variety of depositional textures and fabrics. Pore systems in these deposits have a primary relation to the dominant ...
-
Lee, Janie Anne (2009-05-15)There is strong evidence that variations in seawater chemistry occurred during the Phanerozoic Eon. Of particular importance are the changes in the Mg2+/Ca2+ ratio because they have been attributed to the oscillations ...
-
Chung, Jae Won (Texas A&M University, 2004-09-30)I have studied syntectonic veins from shales and coarse calcareous sands of the Ordovician Womble Shale, Benton uplift, Arkansas. All veins are composed of calcite with minor quartz and trace feldspar and dolomite or high-Mg ...
-
Liu, Xiaoqing (2022-06-24)Over the past 66 million years (Myr), the Earth transitioned from a warm, ice-free greenhouse climate of the early Cenozoic to a cold icehouse climate with glaciated poles of the late Cenozoic. The late Miocene (~11.6-5.3 ...
-
Barney, Bryce B (2020-10-26)Throughout the Phanerozoic, δ18O of carbonate fossils displays an increasing trend of -8‰ VPDB in the Cambrian to approximately -1‰ VPDB in the modern. This trend has led to three different hypotheses: 1) sea surface ...
-
Woodard, Stella C. (2012-07-16)Global climate is controlled by two factors, the amount of heat energy received from the sun (solar insolation) and the way that heat is distributed Earth's surface. Solar insolation varies on timescales of 10s to 100s of ...
-
Harris, William Maurice (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 ...
-
Wagner, Amy Jo (2011-02-22)The Gulf of Mexico and Caribbean Sea comprise a sensitive and important region, both oceanographically and climatically. A better understanding of the history of climate and marine environmental conditions in this region ...
-
Lake, Graciela Esther (Texas A&M University, 2004-09-30)Potential arsenic toxicity in different geologic environments is dependent on total arsenic concentration and arsenic bioavailability. It is important to identify the geologic environments that may sequester arsenic because ...
-
Reimi Sipala, Maria Alejandra (2018-05-04)This work focuses on reconstructing changes in atmospheric and bottom water circulation in the Central Equatorial Pacific (CEP) through the last 150 000 years, to examine how atmospheric and oceanic system respond to changes ...
-
Hoffmeister, Kristin Keir (2019-07-12)The Preclassic (1000 BC-250 AD) and Terminal Classic (800-900 AD) periods were dynamic eras of profound change for the lowland Maya of Central America. In particular, dramatic changes in social structures appear to be ...
-
Prince, Kieron Caleb (2020-04-24)This study presents the diagenetic evolution of the Kardiva Platform, Maldives, located in the tropical region of the Indian Ocean off the southwest coast of India. This drowned carbonate platform was susceptible to high ...
-
Hendricks, Jennifer Kathleen (2019-11-08)Methane-derived carbonates occur in siliciclastic settings globally and precipitate from bicarbonate derived from methane oxidation. Methane-derived carbonates, which occur from the Archean to the present, take diverse ...
