Plateau of south-central Missouri, and Bear Cave Hollow (BCH), one of TCC's surface drainage streams, bed load entrainment and transport dynamics of mainly siliciclastic material, was evaluated using hydrological measurements and 670 painted tracer...
Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...
Spatial, temporal, and petrogenetic relationships of basaltic and lamprophyric dikes and sills of the Raton Basin, southern Colorado and northern New Mexico
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Alkali basalts and lamprophyres commonly occur as sheet intrusions along the flanks of continental rifts. The Raton Basin, on the eastern shoulder of the Rio Grande rift, is host...
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) ...
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. Escalating biological...
Structural geology and tectonics of the paleoproterozoic rocks of the Mount Rushmore Quadangle, Black Hills, Souh Dakota
(University of Missouri--Columbia, 2006)
The Paleoproterozoic assembly of Laurentia occurred between ̃1.96 to 1.70 Ga, and continued with the accretion of island arc terranes until about 1.63 Ga. The Black Hills, South Dakota lie along the eastern margin of the ...
GPS measurements of present day crustal deformation within the Lebanese Restraining Bend along the Dead Sea Transform
(University of Missouri--Columbia, 2008)
/yr uncertainties. The improved spatial coverage and reduced uncertainties allow constructing; 1) elastic fault models that explore strain partitioning between two strike slip faults (Yammouneh and Serghaya faults) and a generalized off-shore thrust fault...
Neotectonic and geophysical investigation into the active growth of the Avawatz Mountain Front, California
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Avawatz Mountains are an actively growing range near the intersection of the Garlock and southern Death Valley Fault Zones in eastern California. The Sheep Creek Fault (SCF...
Igneous intrusions and thermal evolution in the Raton Basin, CO-NM: contact metamorphism and coal-bed methane generation
(University of Missouri--Columbia, 2006)
Tertiary mafic dikes and sills intrude coal-bearing formations of the Raton Basin. This study investigates the role of intrusions in generating methane from coal. Coal samples at four different outcrops were analyzed by ...
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 factors, the rates at which...
Earthquakes in central eastern United States (CEUS) : spatiotemporal patterns and correlations with tectonic factors
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Earthquakes have a history of predominantly occurring along plate boundaries; however, there have been notable exceptions -- the occurrence of earthquakes in supposedly 'stable...
Regional site response and uppermost mantle seismic structure of central and eastern united states
(University of Missouri--Columbia, 2019)
This dissertation examines seismological data from regional earthquake sources in order to examine the seismological character of the crust and uppermost mantle in central and eastern United States. Firstly, site amplification ...
Propagation of regional seismic phases (Sn and Lg) in the Middle East and East Asia
(University of Missouri--Columbia, 2021)
I have studied the propagation of the regional seismic waves (Sn and Lg) in the Middle East (ME) and East Asia. The methods used in this study are : (1) the reverse two-station method (RTM) to determine the attenuation and ...
Fluid inclusion and oxygen isotope studies of high-grade quartz-scheelite veins at the Cantung Mine, Northwest Territories, Canada: products of a late-stage magmatic-hydrothermal event
(University of Missouri--Columbia, 2006)
High-grade quartz-scheelite veins in the Open Pit orebody, Cantung occur 300 m above a limestone-monzogranite contact where the E-Zone orebody, a world-class tungsten skarn, is developed. Adjacent to these veins, alteration ...
Fault evolution and earthquakes : a finite element study
(University of Missouri--Columbia, 2006)
The New Madrid Seismic Zone (NMSZ) in central United States is a good example of intraplate seismicity, which cannot be readily explained by the plate tectonics theory and remains poorly understood. I have developed a 3D ...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
Over 500 million people live in proximity of an active volcano globally. Although lava flows rarely endanger human life, they often destroy critical infrastructure. Advancing our understanding of lava flow dynamics is ...
