Assessing risk and potential reuse of hard rock mine drainage passive treatment residual solids
(2021-08)Ecologically engineered mine drainage passive treatment systems rely on a series of biogeochemical reactions to decrease concentrations of ecotoxic trace metals and have proven to be an effective way to improve water quality ... -
Brine Driven Alteration of Phyllosilicates
(2024-04-16)The sedimentary structures and mineralogy of the Martian surface record a complex and inconsistently active hydrosphere throughout the planet’s history (Bibring et al., 2006; Elwood Madden et al., 2009). Phyllosilicates ... -
Calcite-water reaction rates at reservoir conditions.
(2002)A numerical model was developed for predicting calcite scale precipitation in near-wellbore regions during water flooding and petroleum recovery operations. Rate equations based on the experimental studies were used to ... -
Chemical remagnetization caused by burial diagenesis: Testing the hypothesis in the Pennsylvanian Belden Formation, Colorado.
(1997)The TVRM present in Belden carbonates is pervasive whereas the CRM is widespread but site specific, thus providing an opportunity to magnetically characterize the two components. Specimens with the CRM have higher saturation ... -
A comprehensive geological, geochemical, and petrogenetic study of hotspot-related oceanic basalt-rhyolite series rocks from Ascension Island, South Atlantic Ocean.
(1997)The mafic rocks (basalt-hawaiite-mugearite-benmoreite) of Ascension Island form four distinct groups: low Zr/Nb hawaiite, high Zr/Nb basalt, intermediate Zr/Nb basalt to benmoreite, and Dark Slope Crater (DSC) hawaiite and ... -
Experimental determination of partition coefficients for calcium, strontium, and barium in aragonite precipitated from sea water at low temperatures /
(The University of Oklahoma., 1969) -
Geochemical characterization of organic matter in Victoria Harbour sediments, Hong Kong.
(2006)The organic carbon-to-nitrogen ratio demonstrated fluctuations in the sources of organic matter throughout the Holocene unit of MBH 54/2. High fluxes in the carbon-to-nitrogen ratio may reflect strong storms, where excess ... -
Geochemical characterization of solid bitumen deposited within the Mississippian sandstone reservoir of the Hitch Field, southwest Kansas.
(2006)The occurrence of solid bitumen in petroleum reservoirs is a common phenomenon in many petroliferous basins worldwide. Solid bitumen was recently identified within the Upper Mississippian (Chesterian) sandstone reservoir ... -
High Resolution Sequence Stratigraphy of the Leonardian Bone Spring Formation Outcrop of Bone Canyon, Guadalupe Mountains, West Texas and its Correlation to the Subsurface
(2020-05)The purpose of this Thesis is to analyze the Upper Leonardian Bone Spring Formation, Cutoff Formation, and Early Guadalupian Brushy Canyon Formation in the outcrop of Bone Canyon located along the Western Escarpment of the ... -
Impacts of heterogeneous sedimentary organic matter on phenanthrene sorption and fate processes.
(1999)Natural attenuation is currently one of the most important topics in groundwater management. Sorption and biodegradation are key processes impacting the efficiency of natural attenuation. Although extensive literature has ... -
AN INVESTIGATION INTO THE INFLUENCE OF SUBSURFACE GEOCHEMISTRY ON MICROBIAL COMMUNITIES IN AN UNCONFINED CONTAMINATED AQUIFER
(2018)Microorganisms account for ~ 90 gigatons of carbon in terms of global biomass and are important drivers of elemental cycling especially in oligotrophic subsurface environments. Subsurface ecosystems remain poorly characterized ... -
Iron and sulfur microbial processes applied to the biodegradation of organic contaminants in groundwater.
(1998)This research emphasizes microbial/mineral interactions associated with Fe$\sp{3+}$ and SO$\sb4\sp{2-}$ reduction. Simplified methods are developed to evaluate Fe$\sp{3+}, $ Fe$\sp{2+}, $ and S mineral species. These ... -
Paleoenvironmental interpretation of the Woodford shale with primary focus on water column structure
(2015-05-09)Twenty-nine Woodford Shale rock samples were acquired from the Wyche-1 core derived from the Wyche Farm Shale Pit, Pontotoc County, Arkoma Basin, Oklahoma. The TOC (total organic carbon) values ranged from 3.47-16.90 wt.%, ... -
Petroleum wax deposition and production geochemistry: Experimental results and field examples.
(1999)The present study targets several main aspects of the problem of petroleum wax deposition. The first aspect to be examined is the change in solubility of n-alkane mixtures and wax deposits as related to variability in their ... -
Petrology of the Mount Scott Granite.
(1998)The Mount Scott Granite intruded into the Carlton Rhyolite Group as part of a package of contiguous, consanguineous, and coeval (CCC) granites. Modeling of compositional data suggests the Mount Scott Granite shared a ... -
Petrology, origin and trace element geochemistry of the Ada formation, Seminole and Pontotoc counties, Oklahoma /
(The University of Oklahoma., 1966) -
Source rock geochemistry and liquid and solid petroleum occurrences of the Ouachita Mountains, Oklahoma.
(1981)Several stratigraphic intervals in the Ouachita Mountains possess adequate source potential for petroleum generation, based on contents of total organic carbon and extractable organic matter. Mississippian/Devonian rocks ... -
Stable nitrogen isotope signal in crude oils throughout geologic time
(2017-05-12)Stable nitrogen isotopic compositions of asphaltene and NSO hydrocarbon fractions from sixty-two crude oils derived from siliciclastic, carbonate/marl, hypersaline and lacustrine source rocks of known geologic age ranging ... -
SUBSURFACE AND OUTCROP ORGANIC GEOCHEMISTRY OF THE EAGLE FORD SHALE (CENOMANIAN-CONIACIAN) IN WEST, SOUTHWEST, CENTRAL, AND EAST TEXAS
