2D and 3D modeling of the Laramide fold geometry of Derby Dome and its en echelon interchange with Dallas Dome, southern Wind River Basin, Wyoming
(University of Missouri--Columbia, 2014)The Wind River Mountains of central Wyoming formed as a basement-cored uplift during the Laramide orogeny (ca. ~75-35 Ma) and produced a series of left stepping, en echelon NW-SE trending folds, including Dallas Dome and ... -
Analysis of quaternary faults and associated deformation of sedimentary basin fill: inner continental borderland of southern California
(University of Missouri--Columbia, 2012)The San Andreas fault system is distributed across hundreds of kilometers in southern California. This transform system includes offshore faults along the shelf, slope and across the Gulf of Santa Catalina basin (GSCB) — ... -
Analysis of the interchange between en echelon basin-margin Laramide folds adjacent to the Wind River Mountains, Wyoming
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Uplift of the basement-cored Wind River Mountains during the Laramide orogeny (ca. 75- 45 Ma) produced a series of subsidiary en echelon NW-SE trending ... -
Application of remote sensing techniques to determine the kinematics of the Bull Lake Creek landslide, Wind River Mountains, Wyoming
(University of Missouri--Columbia, 2011)Landslides are one of many natural hazards that impact human settlements. On average, each year landslides account for billions of dollars of property damage and claim thousands of lives around the world. Landslides are ... -
Assessment of environmental variables and anthropogenic impacts on shallow marine bivalves
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Shallow marine bivalves are abundant, diverse, and typically resilient to many changes in their immediate environment. Many bivalves function by filtering ... -
Atrazine transport through a glacial till aquifer in north-central Missouri
(University of Missouri--Columbia, 2009)Although the claypan of North Central Missouri is traditionally believed to protect the groundwater from contamination, low concentrations of the herbicide atrazine have been detected in a shallow glacial till aquifer. The ... -
Bulk oxygen and carbon isotopic variation in the Late Cretaceous along with morphometric analysis of biserial planktonic foraminifera
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Expected δ13C shifts are absent in Tanzanian samples that span the majority of the Turonian Age (93.5 - 89.3 Ma). The δ13C values of bulk carbonate and ... -
Changes in stable carbon isotopes of methane along a salinity gradient in a hypersaline microbial mat system
(University of Missouri--Columbia, 2007)The purpose of this study was to examine how the stable carbon isotopes of methane and possible methanogenic substrates change in microbial mat communities as a function of salinity. Microbial mats were sampled from four ... -
Characterizing the relative timing and conditions of gold and base-metal deposition in the northern part of the Yellowknife Greenstone Belt, Northwest Territories, Canada
(University of Missouri--Columbia, 2011)A complexity of gold-mineralization styles is recognized in the north end of the Yellowknife Greenstone Belt (YGB), ~30 km north of Yellowknife. These include volcanogenic massive sulfides, sulfide zones at intersections ... -
Composition of fluid inclusions from the cave-in-rock bedded-replacement fluorite deposits in the Illinois-Kentucky district
(University of Missouri--Columbia, 2011)The stable mid-continent platform of North America hosts some of the greatest known concentrations of Mississippi Valley-type (MVT) mineralization in the world. Most of the mineralization occurs between two major physiographic ... -
Composition of magmatic fluids in the Harney Peak granite, Black Hills, South Dakota
(University of Missouri--Columbia, 2013)Fluid inclusions are potential trapped samples of magmatic fluids, and they therefore provide a way to directly measure the composition of magmatic fluids. Understanding the composition of magmatic fluids is important ... -
A comprehensive study of marine sediments of NanTroSEIZE Project, offshore Japan: clay mineralogy, consolidation, and microfabric
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation investigates the clay mineral assemblages, consolidation state, and microfabric of sedimentary strata along the Kumano transect of ... -
Constraining the timing of graben initiation in the central Afar using fluvial knickpoint erosion and terrestrial cosmogenic nuclides
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Afar region constitutes the diffuse ridge-ridge-ridge triple junction adjoining the Red Sea, Gulf of Aden, and Main Ethiopian Rifts. Extension in ... -
Crustal stress across the northern Arabian plate and the relationship with the plate boundary forces
(University of Missouri--Columbia, 2013)The region encompassing the collision of northern Arabia with Eurasia is a tectonically heterogeneous region of distributed deformation. The northern Arabia plate is bounded to the west by the subducting Sinai plate and ... -
Dominant substrates used by methanogens in hypersaline environments
(University of Missouri--Columbia, 2010)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The central goal of this study was to determine the dominant substrates used by methanogens in the salt ponds of Elkhorn Slough, the Don Edwards National ... -
Dynamic links between short-term deformation and long-term tectonics: a finite element study
(University of Missouri--Columbia, 2009)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Geodetic and geological data for crustal deformation are significantly different in many places. This discrepancy may indicate different strain rates ... -
Earthquake interaction along the Sultandagi-Aksehir fault based on InSar and coulomb stress modeling
(University of Missouri--Columbia, 2008)The evolution of geologic structures along active faults is influenced by crustal deformation associated with several repetitions of the earthquake cycle, in addition to surficial processes accompanying geologic time. This ... -
Effect of increasing trimethylamine and organic matter concentration on stable carbon isotopes of methane produced in hypersaline, substrate limited environments
(University of Missouri--Columbia, 2013)Substrate limitation has been proposed as an explanation for 13C enriched methane production from endoevaporite microbial communities in hypersaline environments. To test this possibility, methane production rates and ... -
