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 ...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
Mississippi Valley-type (MVT) deposits represent enrichments of base metals and other elements up to 1000's of times greater than their average concentrations in the Earth's crust. These enrichments most commonly consist ...
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...
Orogeny-modified lithosphere
(University of Missouri--Columbia, 2021)
One of the major mantle reservoirs on Earth is the continental lithospheric mantle. Our understanding of the early continental lithosphere sometimes is limited by its subsequent complex history. Continental tracts can be ...
