Active deformation of the South Granite Mountain Fault System : reactivated compressional faults vs. extensional overprinting
(University of Missouri--Columbia, 2022)
the Sweetwater Graben. Recent Quaternary deformation is expressed as fault scarps along the north side of the Granite Mountains (2-4 meters). These features were originally studied in the 1980s but have received little attention since. In particular, the nature...
Metamorphism of the Wales Group and Moira Group on Prince of Wales and Dall Islands, southeastern Alaska
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study examines the metamorphic history of the Proterozoic to Early Ordovician Wales Group and the newly-named Ordovician to Silurian Moira Group ...
Structural geology, tectonic geomorphology, and neotectonics of the central Afar Rift, Ethiopia and Djibouti
(University of Missouri--Columbia, 2018)
pervasive datum to quantify the regional finite strain and fault scaling laws. To this end, I mapped and measured more than 8500 normal faults using remote sensing products. Fault length generally follows a power law distribution, but exponential...
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 ...
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 ...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
sizes, while the empirical equation of Bagnold (1980) performs much better. Thus, the Shields equation may be better suited as a gage for complete mobilization of a grain size class across a reach, while the Bagnold (1980) equation may be better suited...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
the F-rich fluids ascended was critical for allowing the fluids to retain their F-rich, acidic profile until the fluids entered the limestone host rocks. Further, the models showed that high ore fluid F concentrations of 100's to 1000's of ppm were...
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 ...
Emplacement styles of obsidian lavas: an integrated field and laboratory study
(University of Missouri--Columbia, 2021)
, Valles caldera, NM, and Obsidian Dome, Inyo Craters, Long Valley, CA are like the lavas from Cordon Caulle and Chaiten respectively and were the subject of scientific research drilling in the 1980's, providing spatially well-constrained samples that can...
Temporal trends in the Holocene: exploring implications for conservation paleobiology through quantitative assessment of marine mollusks
(University of Missouri--Columbia, 2018)
Conservation paleobiology is a relatively new field which applies the theories and analytical tools of paleontology to problems concerning the conservation of biodiversity. The use of data from stratigraphy, sediment or ...
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 ...
The effects of volatiles on the viscosity and heat capacity of calc-alkaline basaltic and basaltic andesite liquids
(University of Missouri--Columbia, 2014)
Calc-alkaline basaltic magmas are volumetrically important at continental and island volcanic arcs, yet their thermal and physical properties are poorly described. These basaltic magmas are characteristically hydrous, and ...
