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 ... -
Constraining the timing of graben initiation in the central Afar using fluvial knickpoint erosion and terrestrial cosmogenic nuclides
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Afar region constitutes the diffuse ridge-ridge-ridge triple junction adjoining the Red Sea, Gulf of Aden, and Main Ethiopian Rifts. Extension in ... -
Fluorine concentrations of ore fluids in the Illinois-Kentucky district : evidence from SEM-EDS analysis of fluid inclusion decrepitates
(University of Missouri--Columbia, 2016)The Illinois-Kentucky district is an atypical occurrence of Mississippi Valley-type (MVT) mineralization that consists predominantly of fluorite rather than metal sulfide minerals. A long-standing assumption for the ... -
Geochemistry, petrogenesis and tectonic setting of igneous rocks of the Hartville uplift, Eastern Wyoming
(University of Missouri--Columbia, 2016)The location of the eastern margin of the Wyoming Archaean Province and its Proterozoic evolution are still debated. Previous studies have attributed north-south and east-west directed structures to the Proterozoic Black ... -
Gold in the Northern Yellowknife Greenstone Belt, Canada and Pb-Zn-Cu in the MVT deposits of S.E. Missouri : geochemical studies and numerical models
(University of Missouri--Columbia, 2016)Numerical and geochemical studies were performed in this thesis to investigate the formation of ores in (1) the gold-bearing northern Yellowknife Greenstone Belt (YGB), Canada and (2) the southeastern Missouri Mississippi ... -
Morphology, taphonomy, and paleoecology of terminal ediacaran vermiform fauna
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As signposted by the fossil record, the early Cambrian Period chronicles the appearance and evolutionary diversification of most animal phyla in a ... -
Paleoproterozoic metamorphic, structural, and tectonic evolution of the Hartville Uplift, Southeastern Wyoming
(University of Missouri--Columbia, 2016)The Hartville Uplift (HU) of southeastern Wyoming lies near the intersection of two major Paleoproterozoic crustal boundaries, the Cheyenne Belt (CB) and the Dakotan Orogen. Previous structural and geochronologic studies ... -
Rheology of crystallizing basalts from Nyiragongo and Nyamuragira volcanoes, D.R.C.
(University of Missouri--Columbia, 2016)Nyiragongo, a stratovolcano located within the Virunga Volcanic Province on the western branch of the East African Rift, is known for its persistent lava lake activity as well as devastating eruptions in 1977 and 2002. The ... -
Uppermost mantle shear wave attenuation in China
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] We have used attenuation tomography of the regional seismic phase Sn to characterize the uppermost mantle shear wave Q (Qs) over a large part of China. ...
