At the Lisbon Valley Mining Company (SE Utah), exploration for sedimentary-hosted copper deposits has used both conventional soil sampling and sampling of ant hills for surface geochemistry. Anthill prospecting is a sampling technique that exploits the ants’ natural sorting ability as they transport material from the subsurface. The data sets for each of these techniques can be compared using Geographic Information Systems (GIS) to evaluate the...

Monoclines on the Colorado Plateau are well understood in cross-section, but changes along strike are poorly understood. The Hogback monocline, on the Navajo Nation in northwest New Mexico, has multiple bends in map view. This study used geomechanical modeling (T7) and field data (fracture patterns) to explore the possible geometries of faults that created the bends. My research group hypothesized that under the Hogback monocline there are two possible...

The existence of authigenic and reworked clays in fault zones is well understood to control the hydrologic and mechanical properties of faults. The net effect these clays have on fluid conductivity, reservoir quality, and fluid-derived mineralization is dependent on the origin of the gouge. To address this topic, I collected samples along four high-angle normal faults exposed within a copper mine in Lisbon Valley of Southeast Utah. The GTO, Lisbon...

The Powderhorn Complex is composed of carbonatite and several varieties of alkaline ultramafic rocks that include ijolite, uncompahgrite, pyroxenite, and nepheline syenite. Sr and Nd isotope data and bulk rock geochemistry collected in this study were combined with data from previous studies to gain further insight into the magma source and history of the rocks in this complex.
87Sr/86 Sr ratios range from 0.703106 to 0.703632 and εNd values from...

In Lisbon Valley, Utah, Early Cretaceous braided stream deposits of the Lower Burro Canyon Formation form the primary host beds for high-grade copper ore bodies that are potential targets for in-situ leach mining. Variations in the lithology, facies associations, and depositional architecture of the Lower Burro Canyon Formation represent major controls on the porosity, permeability, and connectivity of ore host beds, and are poorly understood in this...

The Victory Pluton, a Devonian aged granite in northeastern Vermont, is thought to have intruded during movement on the Monroe Fault. Metamorphic rocks in the contact aureole provide clues about the pressure and temperature changes during intrusion of the magma. The goal of this research project is to observe the metamorphic reaction textures within one sample from the eastern (uplifted) side of the fault to examine the temperature and pressure changes...

Memes are theoretical cultural replicators. Memetics as a discipline may offer insights into human evolution, particularly as a biological explanation for culture. If memes are real, they should have played a large role in human evolution and should matter with regards to sexual selection. Terror Management Theory (TMT) offers insights into culture as well, positing that humans under fear of death will invest more heavily within their cultural icons....

Musicians and audio professionals are constantly confronted with an abundance of signal processing devices to alter or improve the quality of both recordings and performances. The last few decades have brought digital signal processing forward as a viable alternative to traditional equipment. Despite this, analog systems still represent a large part of the market. While digital systems provide us with the convenience and flexibility of modern technology,...
