Rare Earth Element Transport In The Yucca Mountain Region, Liqiong Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

In sync with environmental pollution of solutes in nature, from source, process to consequence, geochemical processes (leaching and sorption) and hydraulic transportation of the rare earth elements (REEs) have been investigated at Yucca Mountain (YM), Nevada. This research includes the leaching behavior of trace elements (including REEs) from aquifer rocks, the surface complexation reactions of REEs in synthetic groundwater, and transportation of reactive REEs in the local-scale groundwater system of YM. This dissertation includes three projects. These studies indicate that surface complexation reactions may retard the transportation of REEs along groundwater paths in YM, which suggests a similar behavior of …

A Study Of Fold Characteristics And Deformation Style Using The Evolution Of The Land Surface: Zagros Simply Folded Belt, Iran, Caroline M. Burberry, John W. Cosgrove, Jian-Guo Liu

Department of Earth and Atmospheric Sciences: Faculty Publications

Deformation styles within a fold-thrust belt can be understood in terms of the spatial organization and geometry of the fold structures. In young fold-thrust belts such as the Zagros, this geometry is reflected topographically by concordant landform morphology. Thus, the distribution of deformation structures can be characterized using satellite image analysis, digital elevation models, the drainage network and geomorphological indicators. The two distinct fold types considered in this study (fault-bend folds and detachment folds) both trending NW-SE, interact with streams flowing NE-SW from the High Zagros Mountains into the Persian Gulf. Multiple abandoned stream channels cross fault-bend folds related to …

Assessment Of Row Crop, Alfalfa, And Pasture Field Practices On Groundwater Quality In An Upland Bedrock Setting, Henderson County, Kentucky: Report Of Soil- And Water-Quality Data, E. Glynn Beck, James S. Dinger, John H. Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

An assessment of how present agricultural practices have influenced shallow groundwater and soil quality was conducted on a 540-acre farm in north-central Henderson County. Groundwater- and soil-quality data were collected from row crop (corn and soybean), alfalfa, and pasture fields. In addition to the field settings, groundwater and soil data were collected from the existing farmyard and an abandoned feedlot. Groundwater samples were analyzed for pH, specific conductance, temperature, oxidation-reduction potential, metals, anions, nutrients, herbicides, and various isotopes. Soil samples were analyzed for pH, bioavailable phosphorus, potassium, calcium, magnesium, zinc, organic matter, total nitrogen, and inorganic nitrogen (nitrate-N). Soil- and …

Soil- And Groundwater-Quality Data For An Abandoned Cattle And Hog Feedlot In Henderson County, Kentucky, E. Glynn Beck, James S. Dinger, Eugenia Pena-Yewtukhiw, John H. Grove

Information Circular--KGS

Groundwater samples collected from a livestock well in southwestern Henderson County, Ky., contained nitrate-N concentrations greater than 20 mg/L, two times the U.S. Environmental Protection Agency’s maximum contaminant level. The well is located in an abandoned cattle and hog feedlot. The feedlot is located in an upland bedrock setting with Pleistocene loess overlying Pennsylvanian bedrock. One hundred twenty-one soil cores were collected to better define the areal extent of organic-rich soil believed to be the source of the elevated nitrate-N in the groundwater. Cores were collected on 25-ft centers to a depth of 4 ft below the land surface. Soil …

Paleogeographic, Paleoceanographic, And Tectonic Controls On Early Late Ordovician Graptolite Diversity Patterns, Daniel Goldman, Shuang-Ye Wu

Department of Earth, Environment and Sustainability Faculty Publications

The Katian Age (early Late Ordovician) was a time of significant decline in marine biodiversity, but whether this decline was a real phenomenon or an artifact of the relatively few studies devoted to this interval requires further research. We examined the pattern of graptolite faunal changes across the boundary between the Climacograptus bicornis and Diplacanthograptus caudatus graptolite zones in North America and on several other continents.

A sharp decline in species diversity occurs in the Appalachian Basin. Scores for normalized diversity dropped from 20 in the C. bicornis Zone to 7 in the D. caudatus Zone. Only 11% of the …

Lacustrine Sediment Record Of Multiple Quaternary Lava Dams On The Owyhee River, Southeastern Oregon, Caitlin Anne Orem

All Master's Theses

Multiple lava dams and correlating lakes impacted the Quaternary evolution of the Owyhee River. Sediment records from lava-dammed lakes were investigated to understand effects of the West Crater (WC) lava dam (~70 ka), the Saddle Butte 2 lava dam (~144 ka), and the Bogus Rim lava dam (~1.9 Ma). Evidence from the WC lava dam and related features indicates that dam duration consisted of five stages (1) dam and lake formation at ~70 ka; (2) dam overflow and lake sedimentation from ~70–46 ka; (3) removal of lava dam and lake termination from ~46 ka to at least 36 ka; (4) …

Department of Earth, Environment and Sustainability Faculty Publications

Understanding the evolution of humans and our close relatives is one of the enduring scientific issues of modern times. Since the time of Charles Darwin, scientists have speculated on how and when we evolved and what conditions drove this evolutionary story. The detective work required to address these questions is necessarily interdisciplinary, involving research in anthropology, archaeology, human genetics and genomics, and the earth sciences. In addition to the difficult tasks of finding, describing, and interpreting hominin fossils (the taxonomic tribe which includes Homo sapiens and our close fossil relatives from the last 6 Ma), much of modern geological research …

Riparian And Associated Habitat Characteristics Related To Nutrient Concentrations And Biological Responses Of Small Streams In Selected Agricultural Areas, United States, 2003–04, Ronald B. Zelt, Mark D. Munn

United States Geological Survey: Publications

Physical factors, including both in-stream and riparian habitat characteristics that limit biomass or otherwise regulate aquatic biological condition, have been identified by previous studies. However, linking the ecological significance of nutrient enrichment to habitat or landscape factors that could allow for improved management of streams has proved to be a challenge in many regions, including agricultural landscapes, where many ecological stressors are strong and the variability among watersheds typically is large. Riparian and associated habitat characteristics were sampled once during 2003–04 for an intensive ecological and nutrients study of small perennial streams in five contrasting agricultural landscapes across the United …

The Effect Of Vegetated Roofs On Acid Precipitation Runoff, Jennifer Gillen

Geology Theses and Dissertations

Vegetated, or “green” roofs are used in urban architecture and sustainable building to capture stormwater and enhance urban wildlife. Most research to date has focused on their water retention capabilities, but green roofs also have the potential to treat anthropogenic acid precipitation in urban environments. More specifically, green roofs could reduce sulfate, nitrate and hydrogen ion concentrations in runoff. One previous study has demonstrated that nitrate was reduced in water draining from a green roof (Berndtsson, et al. 2006), but this unpublished thesis appears to be the first comprehensive study of the effects of vegetated roof materials on major ions …

Evolution Of The Cretaceous Calcareous Nanofossil Genus Eiffellithus And Its Biostratigraphic Significance, Jamie L. Shamrock, David K. Watkins

Department of Earth and Atmospheric Sciences: Faculty Publications

The calcareous nanofossil genus Eiffellithus is an important taxon of mid- to Upper Cretaceous marine sediments in biostratigraphy and paleoceanography. The definition of species within Eiffellithus have been both broadly interpreted and variably applied by nanofossil workers. This is particularly true for the Eiffellithus eximius plexus. While the taxonomy of mid-Cretaceous Eiffellithus species has recently been well-defined, the remaining 35 m.y. history of the genus has not been closely examined. Our investigation of Cenomanian to Maastrichtian sediments from the Western Interior Seaway, Gulf of Mexico, and Western Atlantic gives rise to six new species of Eiffellithus that can be reliably …

Two-Dimensional Gravity Modeling Of The Rattlesnake Springs Watershed, Carlsbad Caverns National Park, New Mexico, Nikolay D. Boykov

Open Access Theses & Dissertations

A series of non-invasive geophysical investigations at the Rattlesnake Springs part of Carlsbad Caverns National Park, New Mexico, were performed in an effort to better delineate the watershed of the springs. The goal of this project is to determine possible locations of fractures and faults that may control the distribution of groundwater that feeds Rattlesnake Springs. Once the water flow paths are identified, the park will be able to better protect Rattlesnake Springs from environmental hazards, such as oil and gas drilling, as well as from upstream water development. As part of this effort I conducted a precision gravity survey …

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith

Mammoth Cave Research Symposia

One hundred years ago, a young German engineer named Max Kämper, came as a visitor to Mammoth Cave. He became so enchanted with the cavern he obtained permission to map the vast system. For the next eight months Max, along with assistance from cave guide Ed Bishop, meticulously put together a highly detailed and accurate map revealing more of the cave than ever before. He probably never realized his work would be admired by generations to follow. Some admire its artistic expression of the cave. Others see beauty in its precision. Ultimately, it has become the iconic map for generations …

Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons

Mammoth Cave Research Symposia

Serving as guides and explorers at Mammoth Cave partially rescued four men from the obscurity of enslavement. Stephen Bishop, Materson Bransford, Nicholas Bransford and a young man named Alfred all had their very existence documented in the written journals and diaries of various nineteenth century Mammoth Cave visitors. They were physically described, their personalities contemplated, their intelligence gauged, their dialects imitated. At least one abolitionist characterized Stephen Bishop as a charismatic natural leader who could govern the citizenry of freed men in Liberia, should he choose to relocate there.

Max Kämper’S Introduction To The New World, Stanley D. Sides, M.D.

Mammoth Cave Research Symposia

Twenty-seven year old engineer Max Eduard Kämper arrived in America at 4:00 pm on May 16, 1907 and was greeted by a thunderstorm. His presumed goals were to study American manufacturing methods, learn English, and enrich himself musically. New York had so many German immigrants at the time that German was the second most common language spoken in the city. He stayed at the Belvedere House at the corner of 4th Avenue and 18th Street, and the next day visited acquaintances in Newark. He visited New York landmarks and May 20 visited the famed Hippodrome theater. He moved on May …

Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan

Mammoth Cave Research Symposia

In 1908 the German engineer Max Kämper mapped 35 miles of Mammoth Cave, KY. The “Kämper Map,” forgotten in the archives for half a century, is nowadays considered as a masterpiece of underground cartography. Little was known about Max Kämper despite several attempts of American speleo-historians. Most traces were wiped out in two world wars. Nevertheless the authors could find out details of the biography of Max Kämper in German archives. The text is based based upon the radio story “Suche nach Max,” broadcasted by Hessischer Rundfunk - hr1 December 26, 1999, audio download available on http://www.kliebhan.de/kaemper.htm

The Lamps That Lit Their Way, Rick Olson

Mammoth Cave Research Symposia

The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …
