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 ... -
Geochemical studies of gold mineralizing events in the Discovery-Ormsby and Clan Lake areas of the Yellowknife Greenstone Belt, Northwest Territories, Canada
(University of Missouri--Columbia, 2013)Metavolcanic rocks of the mafic Discovery-Ormsby area and the intermediate to felsic Clan Lake area are sites of active gold exploration in the north end of the Yellowknife Greenstone Belt (YGB), Northwest Territories, ... -
A geochemical, taxonomic, and phylogenetic investigation of Paleozoic arthropods : case studies on the Cambrian spice event and the Silurian Waukesha Lagerstatte
(University of Missouri--Columbia, 2020)This thesis details two stand-alone projects: Chapters 1 and 2 comprise a quantitative investigation of controls on the [delta]13C record of the Steptoean Positive Carbon Isotope Excursion (SPICE); Chapter 3 describes a ... -
Geochemistry and fluid evolution of a carboniferous-hosted sphalerite breccia deposit, Isle of Man
(University of Missouri--Columbia, 2008)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Base-metal sulfide deposits have been mined historically on the Isle of Man, principally from large quartz-vein deposits hosted in Ordovician-Silurian ... -
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 ... -
Geochemistry and reaction path modeling of the Beowawe hydrothermal system, Nevada : a barren end-member epithermal system
(University of Missouri--Columbia, 2010)The Beowawe geothermal area is manifested by numerous hot springs, fumaroles, and before the installation of an electric power plant, spectacular geysers. Beowawe also bears many geologic similarities to ancient epithermal ... -
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 ... -
The geography of Boone county : historical and economic geography
(University of Missouri--Columbia, 1915)This thesis discusses the geographical concerns of Boone County including its location, agriculture, economic dependencies, transportation capabilities, and people. The authors attempts to show correlation between the ... -
Geologic mapping, structural analysis, and paleostress modeling of late-stage N-S laramide shortening in the lander NW quadrangle, Wind River Basin, Wyoming
(University of Missouri--Columbia, 2015)Uplift of the basement-cored Wind River Mountains during the Laramide orogeny (ca. 75-45 Ma) produced a series of en echelon NW-SE trending basin margin folds along the southwestern margin of the Wind River basin. The ... -
A geologic section along the north side of the Missouri River from Providence, Missouri to North Jefferson, Missouri
(University of Missouri--Columbia, 1917)The purpose of the field work was, primarily, to collect sufficient data from measurements made at numerous points along the northside of the Missouri River to draw acourately, in a structure section, the contacts of the ... -
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 ... -
