Flow and heat transfer properties of Mono Craters rhyolites : effects of temperature, water content, and crystallinity
(University of Missouri--Columbia, 2008)
The nature of volcanic processes, including rate of magma ascent, exsolution of volatiles, eruption style, and flow distance, is highly dependent on the viscosity of the associated magma and its ability to transfer heat. ...
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...
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 ...
Emplacement styles of obsidian lavas: an integrated field and laboratory study
(University of Missouri--Columbia, 2021)
Previously accepted models of emplacement dynamics of obsidian lavas have recently been called into question by observations made during the effusive eruptions of Chaiten in 2008-2009 and Cordon Caulle in 2011-2012 in ...
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 ...
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 ...
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 ...
Seismic tomography and anisotropy : studies of intraplate seismic zones
(University of Missouri--Columbia, 2009)
Both body and surface wave tomography has been applied to some significant intraplate seismic zones to explore the cause of intraplate earthquakes. Pn tomography in the Central and Eastern United States reveals that the ...
Orogeny-modified lithosphere
(University of Missouri--Columbia, 2021)
One of the major mantle reservoirs on Earth is the continental lithospheric mantle. Our understanding of the early continental lithosphere sometimes is limited by its subsequent complex history. Continental tracts can be ...
Taphonomic characteristics of fossils on the burgessshale-type spectrum
(University of Missouri--Columbia, 2018)
"Study of exceptional fossil preservation tends to yield exciting results. Since soft-bodied organisms and the soft tissues of biomineralizing organisms are usually not preserved in the fossil record, instances of soft-tissue ...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
The study of coprolites and their internal constituents has previously employed a predominantly destructive means of extraction, resulting in the partial or complete loss of the specimen. Recently, however, there have been ...
Late cretaceous ocean circulation in the south Atlantic and Pacific oceans
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cooling during the last 15 million years of the Cretaceous is widely believed to have resulted in a reorganization of ocean circulation, with cooler periods being associated...
Fluid inclusion evidence for the nature of fluids associated with recrystallization of quartzites in the EJB contact Aureole, California
(University of Missouri--Columbia, 2009)
The purpose of this study was to look at the control of fluids and fluid composition on recrystallization of quartzites in the Eureka Valley - Joshua Flat - Beer Creek pluton contact aureole (EJB), in the White - Inyo ...
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 ...
