Seismic anisotropy beneath the southern Puna Plateau
(University of Missouri--Columbia, 2009)
The central Andean plateau is a prime region to study mantle flow above an active plateau margin, where it has been suggested that a link exists between plateau uplift and removal of the lower crust and lithospheric mantle. ...
Taxonomy, taphonomy, and ecology of Silurian (late Telychian) conulariids from the Waukesha Lagerstatte, Wisconsin
(University of Missouri--Columbia, 2021)
) borrowed from the University of Wisconsin Geology Museum, Madison, USA were examined using a combination of light microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy (SEM-EDS), to assist in the classification of these taxa...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
Over 500 million people live in proximity of an active volcano globally. Although lava flows rarely endanger human life, they often destroy critical infrastructure. Advancing our understanding of lava flow dynamics is ...
Emplacement styles of obsidian lavas: an integrated field and laboratory study
(University of Missouri--Columbia, 2021)
Previously accepted models of emplacement dynamics of obsidian lavas have recently been called into question by observations made during the effusive eruptions of Chaiten in 2008-2009 and Cordon Caulle in 2011-2012 in ...
The effects of volatiles on the viscosity and heat capacity of calc-alkaline basaltic and basaltic andesite liquids
(University of Missouri--Columbia, 2014)
Calc-alkaline basaltic magmas are volumetrically important at continental and island volcanic arcs, yet their thermal and physical properties are poorly described. These basaltic magmas are characteristically hydrous, and ...
Atypical planetary lavas: rheological evolution of cooling and crystallizing flows from lunar impact melts and cryovolcanic processes
(University of Missouri--Columbia, 2021)
Volcanism is common to many of the solid planets and moons throughout the solar system. On Earth, volcanic research is mainly targeted at hazard assessment and prediction but volcanism on other worlds helps us understand ...
