volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...

question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...

This work focuses on creating a model for the conductive thermal transport properties of rocks using measured thermal diffusivity (D) with the Laser Flash Analysis (LFA) method, which eliminates common errors associated ...

[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...

The central Afar depression offers an opportunity for quantitative analysis of the final stages of continental breakup at a divergent triple junction. Here, Quaternary faulting dissects Plio-Pleistocene flood basalts, ...

) 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...

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 ...

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 ...

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 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. ...

Remote sensing provides a means of assessing potential water resources stored in alpine ground ice; this study focuses on rock glaciers, in particular. A rock glacier is a landform composed of block of loose debris (talus) ...

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 ...

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 ...

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 ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cooling during the last 15 million years of the Cretaceous is widely believed to have resulted in a reorganization of ocean circulation, with cooler periods being associated...
