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 ... -
Active deformation of the South Granite Mountain Fault System: reactivated compressional faults vs. extentional overprinting
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 6/1/2023] Quaternary faulting in and around Wyoming's Wind River Basin may pose a moderate earthquake risk for dams and other infrastructure within the region. The South Granite Mountains Fault Zone, located ... -
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 ... -
Anisotropy and mantle flow of the Indo-Burma subduction zone from shear wave splitting and shear wave splitting tomography
(University of Missouri--Columbia, 2020)The Indo-Burma subduction zone lies on the eastern boundary of the 1500 km long Alpine-Himalayan orogenic belt. Despite highly oblique plate motion with limited arc development, convergence is still ongoing with the potential ... -
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 ... -
Assessing soft tissue preservation in a variety of saline Environments through actualistic decay experiments and an isotopic assessment of pyritized plant fossils from the Mazon Creek, IL
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Most taphonomic pathways for soft-tissue preservation require minerals either forming on the surface of or replacing tissues. Among various other ... -
Assessment of environmental variables and anthropogenic impacts on shallow marine bivalves
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Shallow marine bivalves are abundant, diverse, and typically resilient to many changes in their immediate environment. Many bivalves function by ... -
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 ... -
Atypical MVT, Zn-Cu-rich mineralization in the lower portion of the Bonneterre Dolomite, Viburnum Trend, southeast Missouri, U.S.A.
(University of Missouri--Columbia, 2015)Mississippi Valley-type (MVT) deposits of the Viburnum Trend are typically lead-dominant (Pb:Zn > 5) and occur mainly in the reef-grainstone facies of the upper Bonneterre Dolomite (Cambrian). Recent drilling has encountered ... -
Atypical planetary lavas: rheological evolution of cooling and crystallizing flows from lunar impact melts and cryovolcanic processes
(University of Missouri--Columbia, 2021)Volcanism is common to many of the solid planets and moons throughout the solar system. On Earth, volcanic research is mainly targeted at hazard assessment and prediction but volcanism on other worlds helps us understand ... -
Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. ... -
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 REQUEST OF AUTHOR.] Expected [delta]13C shifts are absent in Tanzanian samples that span the majority of the Turonian Age (93.5 - 89.3 Ma). The [delta]13C values of bulk ... -
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), [about]30 km north of Yellowknife. These include volcanogenic massive sulfides, sulfide zones at intersections ... -

Classification of rock glaciers in southern Colorado based on ice content using radar interferometry and thermal remote sensing
(University of Missouri--Columbia, 2020)Remote sensing provides a means of assessing potential water resources stored in alpine ground ice; this study focuses on rock glaciers, in particular. A rock glacier is a landform composed of block of loose debris (talus) ... -
Composition of fluid inclusions from the cave-in-rock bedded-replacement fluorite deposits in the Illinois-Kentucky district
