Composition of magmatic fluids in the Harney Peak granite, Black Hills, South Dakota
(University of Missouri--Columbia, 2013)Fluid inclusions are potential trapped samples of magmatic fluids, and they therefore provide a way to directly measure the composition of magmatic fluids. Understanding the composition of magmatic fluids is important ... -
Effect of increasing trimethylamine and organic matter concentration on stable carbon isotopes of methane produced in hypersaline, substrate limited environments
(University of Missouri--Columbia, 2013)Substrate limitation has been proposed as an explanation for 13C enriched methane production from endoevaporite microbial communities in hypersaline environments. To test this possibility, methane production rates and ... -
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 ... -
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, ... -
Mechanisms for the formation of spiraled inclusion trails in garnet porphyroblasts from the Precambrian core of the Laramie Mountains, southeastern Wyoming
(University of Missouri--Columbia, 2013)Relationships between deformation fabrics and porphyroblasts have been used to evaluate the metamorphic and deformational histories of mountain belts. However, some porphyroblast-fabric relationships, such as those of ... -
Organic matter remineralization in the sediment of two acid mine drainage lakes
(University of Missouri--Columbia, 2013)Acid mine drainage is a significant environmental problem throughout the world. At Rocky Forks Conservation Area near Columbia, MO numerous lakes have formed from old coal mining pits. Most of these lakes have a pH near ... -
Present-day and late Quaternary crustal deformation along the southern Dead Sea Fault System, Jordan
(University of Missouri--Columbia, 2013)Theoretical models of the earthquake cycle predict that crustal rheology may lead to differences between short-term crustal deformation rates (decadal time scales) and long-term fault slip rates (Holocene to late Pleistocene ... -
Structural geology and contact metamorphism along the northwestern thermal aureole of the Laramie anorthosite complex, Central Laramie Mountains, Wyoming
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The southeastern margin of the Archean Wyoming craton has undergone a complex history of Proterozoic deformation and metamorphism. The Archean rocks ...
