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...

First ladies are an important element in presidential administrations and have parallel structures, as they are in a position to be leaders, have important roles, supported various causes and have tremendous influence over presidents. First ladies have developed this role from scratch, entirely since Martha Washington who built a powerful institution in the federal government. Many first ladies have sponsored programs and causes, and have been role...

Anthropogenic impacts to wildlife populations represent a reoccurring theme in wildlife management as the human population expands into wild landscapes. Our study focused on a great blue heron (Ardea herodias) colony of approximately 20 nests uniquely located along the Slate River near Crested Butte, Colorado. This high mountain stream increasingly draws river recreationists, especially stand-up paddle boarders. Our study assessed how human activities...

Atmospheric concentrations of CO2 have reached unprecedented levels, posing a threat to the health of the biosphere. Soils store the largest amount of terrestrial carbon (C) and can be used as a method for sequestering atmospheric C. The cycling of C between the atmosphere and terrestrial ecosystems is directly influenced by soil microbial activity and respiration. Compost amendments to soil systems have the potential to shift the composition of the...

Within the sagebrush steppe ecosystem in the intermountain west, sagebrush obligate birds occupy a variety of specialized niches. The purpose of our research was to identify the effect of road presence and habitat covariates on the density of sagebrush obligate birds during their breeding season. Roads through sagebrush threaten local bird abundance through anthropogenic disturbance and habitat fragmentation (Knick et al. 2012). However, research...

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,...

The guiding questions of this case study are an ambitious attempt to interpret the experience of ordinary people in Morgan County, especially in its major hub, the city of Fort Morgan, from the 1860s to the present; to chronicle the rise of a community found in the relative isolation of northeast Colorado from a military installation to a municipality, and create an understanding of the socio cultural phenomena that exists today. The central questions...

The stories of the Pig War and the region's Indian Wars have been well documented by authors such as Mike Vouri and Robert Utley, respectively. The telegraph and railroad are components of the larger, territorial and state histories, and are commonly told as such. The questions surrounding loyalty in the territory are woven in through various works, with no singular volume in existence that explores this theme in depth. The story of the American frontier...

Human-wildlife conflicts are increasing as population growth, habitat conversion, and climate change accelerate challenges for species that interface with urban and rural communities. In the Gunnison Valley, like many areas throughout the west, such conflicts are increasing between black bears and city residents. Black bears are adaptable mammals and exhibit different behaviors in response to selective pressures (e.g., temperature and precipitation...
