Carbon Cycling Dynamics Inferred From Carbon Isotope Sourcing In A Mid-Latitude Karst-Influenced River, Kegan N. Mcclanahan

Masters Theses & Specialist Projects

As ever-increasing levels of carbon dioxide alter the chemistry of the Earth’s atmosphere, understanding the global carbon cycle becomes increasingly important. A particularly important component is the riverine carbon cycle, as rivers are the primary conduits for dissolved inorganic carbon from terrestrial watersheds to ocean basins. Stable carbon isotopes (13C/12C) were collected weekly and input into the mixing model IsoSource to delineate seasonal carbon sourcing along two nested basins in the upper Green River System, Kentucky. In the more siliciclastic upstream catchment, dissolved inorganic carbon (DIC) was primarily derived from soil respiration (34%). Groundwater dissolving carbonate bedrock and carbonate dissolution/precipitation …

Schellenberger Ice Cave (Germany): A Conceptual Model Of Temperature And Airflow, Christiane Meyer Cm, Andreas Pflitsch Ap, David Holmgren Dh, Valter Maggi Vm

The International Workshop on Ice Caves

In this paper the primarily results of air temperature measurements from 2007 to 2013 are presented. The focus lies on the climatic description of the thermal conditions of the different ice cave parts and the related conceptual model of the airflow regime. The data will also show seasonal aspects of air temperature caused by the specific winter versus summer conditions. This basic data are the beginning for an interdisciplinary research project, which focuses on the microclimatological and glaciological processes and dynamics of the cave.

Porphyry Copper Exploration Of The Hualapai Mountains, Mohave County, Arizona, Usa: A Multi-Faceted Approach, Patrick Kevin Meazell

UNLV Theses, Dissertations, Professional Papers, and Capstones

A variety of exploration methods including geologic mapping, trace- and major-level geochemical analyses, fluid inclusion petrography, remote sensing, and SWIR clay spectroscopy were used to investigate the potential for porphyry Cu-Mo mineralization at the Wikieup prospect, in the southern Hualapai Mountains of northwestern Arizona. Aspects of the Mineral Park mine were used as an analogue to guide exploration due to the proximity and similar geology of the area.

The Hualapai Mountains are a series of northwest-trending Precambrian gneisses, schists, granitoids and amphibolites that have been cut by younger intrusive rocks. Within the Wikieup study area, the intrusive rocks include aplite …

Surrogate Reservoir Model For Generating Pressure, Saturation And Compositional Characteristics At The Grid-Block Level; Sacroc Field, Scurry County, Texas, David Moreno

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nowadays, due to advancements in data acquisition technologies in oil and gas industry more data are available for generating reservoir simulation models. This leads to high fidelity reservoir simulation models which are highly complex and computationally expensive. The conventional reservoir management studies require hundreds realizations of the simulation models. As S. Gencer (2007) described, the reservoir simulation trend is towards "more: more users, more models, more cells, more wells, more cases, more data and more integration" [1]. In order to enhance the reservoir model descriptions, more computational power would have to be designed and engineered to keep up with our …

Comparing And Contrasting The Us And German Banking System With Emphasis On The Financial Crisis In 2008, Sarah K. Gleissle

Honors College Theses

This thesis will compare and contrast the Financial Systems of the United States and Germany, the structure, institutions and regulations. Furthermore, we investigated the impacts that the Financial Crisis in 2008 had on Financial Systems, the outcomes and effects. First, we looked at both Systems and the structures more closely, and compared them to each other. Next we looked at the regulations and regulatory agencies in both countries and the work they do. We realized that the different competitive natures the banking systems are under influence their businesses and business decisions.

Along Strike Variability Of Thrust-Fault Vergence, Scott Royal Greenhalgh

Theses and Dissertations

The kinematic evolution and along-strike variation in contractional deformation in overthrust belts are poorly understood, especially in three dimensions. The Sevier-age Cordilleran overthrust belt of southwestern Wyoming, with its abundance of subsurface data, provides an ideal laboratory to study how this deformation varies along the strike of the belt. We have performed a detailed structural interpretation of dual vergent thrusts based on a 3D seismic survey along the Wyoming salient of the Cordilleran overthrust belt (Big Piney-LaBarge field). The complex evolution of the thrust faults that parallel the overthrust belt is demonstrated by the switching of the direction of thrust …

Dust And Pleistocene Ice Ages: Eolian Sediments And Climate Change At Ziegler Reservoir, Snowmass Village, Colorado, Jeffrey S. Honke

Electronic Theses and Dissertations

The discovery of the Ziegler Reservoir fossil site near Snowmass Village, Colorado presents an opportunity to examine subalpine ecosystem response, during a relatively unknown period, in which climate conditions were similar to present. Finegrained sediments at Ziegler Reservoir represent continuous deposition between ~140–55 ka (thousand years before present), spanning the close of the Bull Lake glacial period [marine isotope stage (MIS) 6], the Sangamon interglacial (MIS 5) and the early stages of the Pinedale (early Wisconsin) glacial period (MIS 4). Ziegler Reservoir is positioned on top of a ridge, at an elevation of 2705 m, and has a small watershed …

Sedimentological And Stratigraphic Study Of A Falling-Stage Delta Complex In The Upper Cretaceous (Turonian) Ferron Sandstone Member Of The Mancos Shale, South-Central Utah, Usa, Fares Alaboud

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The character and distribution of lithofacies in falling-stage deltas are incompletely documented. This paper presents a sedimentological and stratigraphic evaluation of a superbly-exposed interval of Cretaceous deltaic strata that are believed to be of falling stage origin. The studied interval forms part of the Upper Cretaceous (Turonian) Ferron Sandstone Member of the Mancos Shale in the southernmost Henry Mountains Basin of south-central Utah, USA. The interval of interest is exposed in three dimensions over a 20 km² area in a series of canyon walls. Observed facies include fine-grained mudrocks (offshore basin), mudrocks with thinly interlaminated sandstone (prodelta), thinly interbedded …

Dust Mediated Transfer Of Phosphorus To Alpine Lake Ecosystems Of The Wind River Range, Wyoming, Usa, Janice Brahney, Ashley P. Ballantyne, P. Kociolek, Sarah A. Spaulding, Megan Otu, T. Porwoll, Jason C. Neff

Watershed Sciences Faculty Publications

Alpine lakes receive a large fraction of their nutrients from atmospheric sources and are consequently sensitive to variations in both the amount and chemistry of atmospheric deposition. In this study we explored the spatial changes in lake water chemistry and biology along a gradient of dust deposition in the Wind River Range, Wyoming. Regional differences were explored using the variation in bulk deposition, lake water, sediment, and bedrock geochemistry and catchment characteristics. Dust deposition rates in the Southwestern region averaged 3.34 g m−2 year−1, approximately three times higher than deposition rates in the Northwestern region (average 1.06 g m−2 year−1). …

Subsurface To Surface Correlation Of The Tensleep Sandstone In The West Flank Of The Pryor Mountains In Carbon County, Montana, William B. Rhyne

Graduate Theses & Non-Theses

The Pennsylvanian Tensleep Sandstone is an eolian and nearshore marine/sabka quartz arenite unit with prominent outcrops along the western Pryor/Bighorn Mountain front east of Red Lodge, MT. Regionally, the formation represents one of the largest ergs in the global geologic record. High permeability makes it an important oil and gas reservoir and aquifer in south central Montana and throughout much of Wyoming. The Tensleep Sandstone’s high percentage of quartz content and grain roundness, due to its eolian origin, makes it a prospective source for natural proppant sand.

Three continuous 4-inch cores were obtained during a cooperative project between Montana Tech …

Applications Of Gis Analyses And Ecological Approaches To Paleolithic Sites In Portugal., Christopher M. Sims

Electronic Theses and Dissertations

Developments in landscape approaches to archaeological research have been greatly advanced by the use of geospatial technologies. Despite this boon, certain questions remain where the spatial distributions of archaeological material are complicated by other factors. Geomorphic processes significantly hinder site survivability and visibility, and complicate fieldwork. Such is the case for Paleolithic archaeological sites in Portugal, where the current landscape has been drastically altered since Paleolithic human occupation at the Last Glacial Maximum. The challenge to landscape-scale approaches is to provide a bridge between long-term environmental factors and smaller-scale evidence for human-ecosystem interaction. This requires that adaptations be made to …

A New Spatio-Temporal Data Mining Method And Its Application To Reservoir System Operation, Abhinaya Mohan

School of Computing: Dissertations, Theses, and Student Research

This thesis develops a spatio-temporal data mining method for uncertain water reservoir data. The goal of the data mining method is to learn from a history human reservoir operations in order to derive an automated controller for a reservoir system. Spatio-temporal data mining is a challenging task due to the reasons: (1) spatio-temporal datasets are usually much larger than spatial data sets, (2) many common spatial techniques are unable to deal with objects that change location, size or shape, and (3) complex and often non-linear spatio-temporal relationships cannot be separated into pure spatial and pure temporal relationships.

Early And Late Iron Diagensis In The Upper Triassic Shinarump Member Of The Chinle Formation (Utah And Arizona), Derek T. Burgess

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The fluvial Shinarump Member of the Chinle Formation in southwestern Utah and northwestern Arizona contains several distinct types of diagenetic iron accumulations. They range to more than 50 cm in diameter, and are dominantly composed of iron-oxide cement, but siderite, rhodochrosite and pyrite cements are common. Iron-oxide cements occur in all facies, but are most abundant in channel sandstone bodies. There, iron-oxide-cement occurs as wonderstone fabric (rinds & staining), dispersed rhombic pseudomorphs, and as discoidal concretions within intraformational conglomerates. Evidence from Shinarump sediment indicates that the ferrous carbonate mineral siderite (FeCO₃) was the precursor mineral for current iron-oxide …

"Mythos": A Play In Two Acts About The Ability To Choose, Jacob F. Filegar

Senior Honors Theses

This paper presents a two-act play in the fantasy genre about the ability to choose, titled “Mythos.” The goal of the play is to persuade audience members to consider that regardless of their past, they still have the ability to choose their future. Although this play is written from a Christian perspective, it does not deal directly with Christianity. “Mythos” centers on Margaret, a young woman who is afraid of making the choices necessary to progress her life. Instead, Margaret is waiting on her “call to adventure,” which, according to Joseph Campbell, was the beginning of most heroes’ adventures in …

Graduate School of Oceanography Faculty Publications

We collected continuous seismic data recorded between 2007 and 2010 by 208 broadband stations from the Chinese Provincial Digital Seismic Networks, A Seismic Collaborative Experiment of Northern Tibet, and the Northeastern Tibet Seismic experiment. Cross correlations of vertical component records are computed to extract the Rayleigh wave empirical Green's functions. Group and phase velocities are then constructed from the empirical Green's functions in 8 to 50 s period. At periods ≤25 s, more than 10% lower velocities are imaged beneath the Qaidam Basin, and high velocities are observed beneath the nonbasin regions. At periods ≥30 s, up to 10% lower …

Multi-Scale Neotectonic Study Of The Clear Lake Fault Zone In The Sevier Desert Basin (Central Utah), Brandon D. Heiner

Theses and Dissertations

A multi-scale high-resolution geophysical and geological study was conducted in the Sevier Desert, central Utah, found within the Colorado Plateau-Basin and Range Transition Zone. The region is marked by with Quaternary volcanics and faulting as young as 660 yr B.P., with many fault scarps thought to have the potential for 7+ magnitude earthquakes. Three locations within the Sevier Desert which represent three different tectonic expressions of possible faulting at the surface were selected. These include a location found within surface sedimentation, a location with surface sedimentation and sub-surface basalts and a location with basalts, at the surface with very limited …

A National Mineral Policy As An International Investment Law Stratagem: The Case Of Tajikistan's Gold Reserves, Nadia B. Ahmad

Elisabeth Haub School of Law Faculty Publications

This Article proposes that a national mineral policy ("NMP") can be crafted to generate foreign direct investment ("FDI") and strengthen sustainable development goals. Less-developed countries ("LDCs") typically overlook or underestimate this federal policy imperative while seeking to harness mineral resources.' Creation of a NMP and complementary changes to federal mining investment laws can provide host countries increased opportunities as well as autonomy to profit from their own natural resources and, at the same time, investor nations can benefit from a NMP because of further mining prospects.

This Article goes on to discuss how the formulation and implementation of a NMP …

Bicoelia Corticifera, A New Inozoid Sponge From The Upper Triassic (Norian) Reef Boulders Of The Central Taurids (Southern Turkey), Baba Senowbari-Daryan, Michael Link

Turkish Journal of Earth Sciences

Upper Triassic Norian reef boulders, exposed in a locality in the Central Taurids, southern Turkey, yielded a high number of hypercalcified sponges, including Sphinctozoans, Inozoans, Spongiomorphids, and Chaetetids. The reef boulders are exposed near the fountain Tavuk Çeşme, located at the road leading from the town of Aksu to Yenişarbademli. Geologically this locality belongs to the Anamas Akseki Autochthon. In this paper a new inozoan sponge, Bicoelia corticifera nov. sp., is described from Tavuk Çeşme. It is a cylindrical and unbranched sponge, found in several thin sections. The sponge is characterized by 2 axial spongocoels, and the sponge wall is …

Neotectonics Of The Zanjan-Kazvin Area, Central Iran: Left Lateral Strike‐Slip Induced Restraining Stepovers, Moosarreza Toori, Gürol Seyi̇toğlu

Turkish Journal of Earth Sciences

The neotectonics of the Zanjan-Kazvin area are dominated by the region-wide E-W trending left lateral strike-slip faults. These faults create restraining and releasing stepovers indicating strain partitioning. Instead of the NW-SE trending long range-parallel continuous thrust faulting suggested in previous studies, this paper demonstrates that there are E-W trending range-crossing left lateral strike-slip faults creating short range-parallel thrust faults in the restraining stepovers. Establishing this strike-slip-induced structural style might contribute to an understanding of the nature of the Elburz (Alborz) Mountains located between the Central Iran and Caspian blocks.
