The No. 5 Block In Eastern Kentucky: A Critical Re-Examination Of The Petrology With Special Attention To The Origin Of Inertinite Macerals In The Splint Lithotypes, Allison Ranae Richardson

University of Kentucky Master's Theses

Microbes, including fungi and bacteria, and insects are responsible for the consumption and subsequent degradation of plant materials into humus. These microbes directly and indirectly affect the physical and chemical characteristics of coal macerals. Efforts to understand and determine the origins of inertinite macerals are largely misrepresented in the literature, conforming to a single origin of fire. This study focuses on the variability of physical and inferred chemical differences observed petrographically between the different inertinite macerals and discusses the multiple pathways plant material may take to form and or degrade these macerals.

Petrographic results show that fungal activity plays a …

Tectonic Controls On Lower Devonian Sandstone Distribution, Alabama, Michael P. Solis

University of Kentucky Master's Theses

The Devonian Frog Mountain Formation thickens abruptly eastward across the Eastern Coosa thrust fault from <12 m on the west to>70 m on the east. The thin Frog Mountain on the west unconformably overlies the Cambrian-Ordovician Knox Group. The thin Frog Mountain (mostly shale) is overlain by the Mississippian Maury Shale (~1 m thick) and Fort Payne Chert (~50 m thick). The thick Frog Mountain on the east rests on the Middle Ordovician Athens Shale, a black shale >150 m thick. The Athens overlies the Knox Group. The thick Frog Mountain is nearly all sandstone and is overlain by Fort Payne Chert which is only …

Origin Of Blue Ridge Basement Rocks, Dellwood Quad, Western Nc: New Evidence From U-Pb Zircon Geochronology And Whole Rock Geochemistry, Donald Franklin Loughry Jr.

University of Kentucky Master's Theses

Terrane discrimination in polycyclic continental basement rocks is challenging due to high-grade metamorphism and intense deformation. Based on early USGS mapping the Blue Ridge basement in the Dellwood quadrangle of the eastern Great Smoky Mountains was proposed to consist of augen orthogneisses of Laurentian (Grenvillian) affinity interfolded with migmatitic hornblende and biotite paragneisses (“Carolina Gneiss”) and amphibolites of uncertain affinity. However, detailed study reveals that the hornblende gneiss of Hadley and Goldsmith (1963) is a heterogeneous map unit consisting of (1)metaplutonic rocks; (2) variably foliated and folded felsic orthogneisses; (3) strongly migmatitic, folded Hbl+Bt-bearing gneisses; (4) foliated and lineated garnet …

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 …

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 …

Assessment Of Groundwater Quality In An Abandoned Feedlot, Henderson County, Kentucky: Data Report, E. Glynn Beck, James S. Dinger, John Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

A three-phase project investigated the influence of past and present agricultural practices on groundwater resources in the Western Kentucky Coal Field. Phase II concentrated on past practices, specifically those associated with an abandoned dairy feedlot and an old homestead. Results of phase II analyses are presented in this report.

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky: Data Report, E. Glynn Beck

Information Circular--KGS

Groundwater from the Jackson Purchase Region was sampled to investigate possible contamination by nonpoint-source chemicals. Conclusions drawn from the resulting data and methodology can be found in “Sources and Occurrences of Nonpoint-Source Chemicals in Groundwater, Jackson Purchase Region, Kentucky,” Kentucky Geological Survey Report of Investigations 22 (series 12), by R.S. Fisher and E.G. Beck.

Remaining Resources Of The Springfield Coal, Gerald A. Weisenfluh

Map and Chart--KGS

Historically, the Springfield (W. Ky. No. 9) opal bed has been the leading source of coal production in the Western Kentucky Coal Field. With 2009 production more than 21 million tons and another 8 million tons of idle capacity, it is also the most important resource in the state of Kentucky. The Springfield coal is known for its lateral continuity in terms of both thickness and quality. It is a medium-sulfur product, desirable for power plants with sulfur-reduction capability, and has higher Btu values and lower chlorine contents compared to other Illinois Basin areas north of Kentucky. It is estimated …

Latest Quaternary Paleoclimate Reconstruction Utilizing Stable Isotopic And Trace Element Proxies In A Stalagmite From Culverson Creek Cave, West Virginia, Ashley Nicole Gilbert

University of Kentucky Master's Theses

A reconstruction of regional climate variability in southern West Virginia that spans the last glacial/interglacial transition is presented. Paleoclimate interpretations obtained from the 50-cm long stalagmite provide key insights regarding the timing, magnitude, and forcing mechanisms responsible for past climate variability. Stable isotopic (δ¹⁸O and δ¹³C) and trace element (Ba, Sr, Mg) signatures from samples contiguously milled along the growth-axis of a ²³⁰Th-dated stalagmite which grew between approximately 20 and 5 thousand years before present (kyr BP) provide critical constraints for above-cave mean annual temperature, seasonality of moisture mean annual precipitation, and potential vegetation shifts. …

Evaluation Of Geologic Co2 Sequestration Potential And Co2 Enhanced Oil Recovery In Kentucky, Thomas M. Parris, Stephen F. Greb, Brandon C. Nuttall

Report of Investigations--KGS

Kentucky gets approximately 95 percent of its electricity from coal-fired power plants, which produce significant amounts of carbon dioxide (CO₂). In 2005, Kentucky coal-fired plants vented 102.8 million short tons of CO₂ into the atmosphere. The economic vitality of the state will be affected by its ability to develop and apply a portfolio of technologies that will mitigate input of CO₂ into the atmosphere. One technology that has the potential to assist in this challenge is geologic carbon storage, which captures CO₂ at point sources and injects it into deep rock strata that can store …
