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. ...
The viscosity of dacitic liquids measured at conditions relevant to explosive arc volcanism: determing the influence of temperature, silicate composition, and dissolved volatile content
(University of Missouri--Columbia, 2006)
Viscosity can control various magmatic processes and varies by orders of magnitude as a function of temperature, composition and dissolved volatiles. There is no predictive model for the viscosity of dacitic liquids, which ...
Changes in stable carbon isotopes of methane along a salinity gradient in a hypersaline microbial mat system
(University of Missouri--Columbia, 2007)
The purpose of this study was to examine how the stable carbon isotopes of methane and possible methanogenic substrates change in microbial mat communities as a function of salinity. Microbial mats were sampled from four ...
GPS measurements of present day crustal deformation within the Lebanese Restraining Bend along the Dead Sea Transform
(University of Missouri--Columbia, 2008)
The Lebanese restraining bend is a 200 km long bend with a left lateral sense of slip located along the Dead Sea fault system (DSFS) between 33.2 and 34.6 degrees north latitude. The DSFS is a transform plate boundary fault ...
Spatial, temporal, and petrogenetic relationships of basaltic and lamprophyric dikes and sills of the Raton Basin, southern Colorado and northern New Mexico
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Alkali basalts and lamprophyres commonly occur as sheet intrusions along the flanks of continental rifts. The Raton Basin, on the eastern shoulder of the Rio Grande rift, is host...
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 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 ...
