Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder ... -
Fluid inclusion and oxygen isotope studies of high-grade quartz-scheelite veins at the Cantung Mine, Northwest Territories, Canada: products of a late-stage magmatic-hydrothermal event
(University of Missouri--Columbia, 2006)High-grade quartz-scheelite veins in the Open Pit orebody, Cantung occur 300 m above a limestone-monzogranite contact where the E-Zone orebody, a world-class tungsten skarn, is developed. Adjacent to these veins, alteration ... -
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 ... -
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 ...
