Organic sulfur metabolisms in Eastern Lau Spreading Center hydrothermal vents
(University of Missouri--Columbia, 2012)
. The cultures contained species of Thermococcales, [mu]-Proteobacteria, Thermales, and Aquificales as well as 2 novel bacterial sequences. These data suggest that organic sulfur-based metabolisms may be viable within deep-sea hydrothermal vents....
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 ...
Seismic attenuation of regional phases in the northern Middle East and the Tibetan Plateau
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] I study the regional seismic phase attenuation to (1) infer rheology and temperature of the crust and uppermost mantle and to (2) develop reliable and ...
Receiver function study in northeast Tibet and adjacent boundaries
(University of Missouri--Columbia, 2011)
As part of the NorthEast Tibetan plateau Seismic (NETS) project, we performed receiver functions analysis across the northeastern Tibetan plateau and adjacent boundaries. Using the data of about 500 events obtained from ...
Oxygen isotopes from conodonts of the mid-continent, US : implications for Late Ordovician climate evolution
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] To test competing interpretations of Late Ordovician climate evolution, sea surface temperatures were estimated from oxygen isotope ratios of ...
Geochemistry and origins of Mississippi Valley type mineralizing fluids of the Ozark Plateau
(University of Missouri--Columbia, 2011)
The compositions of fluid inclusions hosted in ore and gangue minerals from Mississippi Valley-type (MVT) Pb-Zn-Ba deposits of the Ozark Plateau region were measured to develop a regional hydro-geochemical conceptual model ...
Permeability, clay mineralogy, and microfabric of fine-grained sediments from the Nankai Trough and Shikoku Basin, offshore southwest Japan
(University of Missouri--Columbia, 2012)
The Nankai Trough, a convergent plate boundary between the subducting Philippine Sea plate and overriding Eurasian plate, is located off the coast of southwest Japan. This study covers the central portion of the Kumano ...
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 ...
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 ...
Unraveling the fluid-present metamorphism of schists from garnet compositions in the Black Hills, South Dakota
(University of Missouri--Columbia, 2012)
Garnets in Proterozoic metapelites in the Black Hills, South Dakota, were analyzed to determine their pressure, temperature and hydrothermal conditions of growth and to elucidate pressure-temperature-time paths of their ...
Late-stage Laramide reactivation of Precambrian structures : evidence for [about]N-S Laramide shortening along the southeastern margin of the Wind River Mountains, Wyoming
(University of Missouri--Columbia, 2012)
Deformation along the southeastern margin of the Wind River Mountains during the late stages of the Laramide orogeny is a result of local [about]N-S Laramide shortening, which is in contrast to the regional NE-SW shortening ...
Fault segmentation and paleoseismicity along the North Wutaishan Fault of the Shanxi Graben System, China
(University of Missouri--Columbia, 2013)
The Shanxi Graben System has been the location of large, devastating intraplate earthquakes in the past, making it an ideal location for the study of the temporal recurrence of intracontinental earthquakes. This study ...
Seismic studies in the Southern Puna Plateu and the Peruvian Andes
(University of Missouri--Columbia, 2014)
I present three studies in two regions, both within the Central Andes. In both regions it is clear that there are significant variations in the subduction geometry. I have used surface wave tomography to investigate the ...
Kinematic analysis of the Debeque Landslide using radar interferometry and change-detection photogrammetry, Mesa County, CO
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Debeque Landslide is an active landslide impacting I-70 in Western Colorado that is the result of displacement along the southern wall of an ...
Stratigraphic variation of the late Cambrian spice event in upper Cambrian carbonates of southern Missouri
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Several positive carbon isotope excursions in lower Paleozoic rocks, including the prominent upper Cambrian Steptoean Positive Carbon Isotope Excursion ...
Two phases of extension in North China since Mesozoic :a numerical study
(University of Missouri--Columbia, 2013)
The North China Craton was formed around 1.8 Ga by collision and amalgamation of the Eastern and Western blocks. It remained tectonically stable since then until the Mesozoic, when its eastern part experienced widely ...
Seismic attenuation of regional phases in the northern Middle East and eastern Tibetan plateau
(University of Missouri--Columbia, 2017)
Temperature and composition are two major causes for subsurface seismic anomalies. Positive temperature anomalies will lead to a reduction in both attenuation and velocity; however, compositional anomalies should not ...
Temperature-dependent thermal transport properties of major Archean rock types and implications for the thermal evolution of Archean terranes
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] While it is generally agreed that plate tectonics operated on Earth in the Proterozoic, a form of vertical tectonics may have operated during the ...
