Use Of Limestone, Lime, And Dolomite For So2 Emission Control In Kentucky, Garland R. Dever Jr.

Information Circular--KGS

Flue-gas desulfurization and atmospheric fluidized-bed combustion systems for sulfur dioxide (SO₂) emission control have been installed at 13 coal- and gas-fired plants and one research laboratory in Kentucky. Limestone, lime, and dolomite are the principal SO₂ sorbents used in these systems.

Nine coal-fired, electricity-generating plants in the State have installed wet-scrubbing systems for flue-gas desulfurization. Lime-based scrubbers are using Thiosorbic® lime, produced from the Camp Nelson Limestone (Ordovician) of north-central Kentucky, and carbide lime, a byproduct from the manufacture of acetylene in Louisville. Limestone-based scrubbing systems at three of the plants have used stone from the Warsaw, …

High-Volume Oil Discovery In Clinton County, Kentucky, Terence Hamilton-Smith, Brandon C. Nuttall, Patrick J. Gooding, Dan Walker, James A. Drahovzal

Information Circular--KGS

The Syndicated Options Limited of Austria No. 9372 Ferguson Brothers well, located in southern Clinton County, Kentucky, has recently produced oil at reported initial rates of 400 to 130 barrels per hour. Cumulative production for the first 8 weeks of flow following discovery on September 25, 1990, is reported to be nearly 150,000 barrels. The well is the result of deepening a previously abandoned well. Production is from the Middle Ordovician High Bridge Group (equivalent to the Stones River Group of Tennessee) at a depth of 1,008 feet. The reservoir is apparently a fractured carbonate rock, and the fracturing is …

Constraints On The Emplacement And Uplift History Of The Pine Mountain Thrust Sheet, Eastern Kentucky: Evidence From Coal Rank Trends, Kieran D. O'Hara, James C. Hower, Susan M. Rimmer

Earth and Environmental Sciences Faculty Publications

In this paper coal rank trends on both sides of the Pine Mountain thrust in eastern Kentucky are used to place constraints on thrust evolution. Vitrinite reflectance () measurements on a single Pennsylvanian coal horizon (Fire Clay coal) in eastern Kentucky increase from 0.5% in the north to about 1.0% toward the SE in front of the Pine Mountain thrust. The same horizon in the hangingwall of the thrust displays lower R_max values (0.8-0.85%). The reflectance isograds are subparallel to the thrust within approximately 10 km of the trace of the fault. We attribute thermal maturation to (1) pre-orogenic …

The Geology Of Taconic Thrust Sheets And Surrounding Carbonates Of The West Central Vermont Marble Belt, North Of Rutland, Vermont, Kay Bierbrauer

Geology Theses and Dissertations

The carbonates of the Vermont Valley and the overlying rocks of the Taconic sequence have been generally believed to lie on the east limb of a major unfaulted syncline (Middlebury Synclinorium). In this view a westward dipping, north-south trending basal Taconic overthrust must be exposed somewhere along the eastern margin of the Taconic Range.
In contrast, this study based on detailed mapping at the north end of the Taconic Allochthon suggests that a folded overthrust surface is only locally seen in fensters; more commonly the basal obduction surface of the Taconic Allochthon has been truncated by later cross-cutting thrust faults. …

Geochemistry Of Garnet Xenocrysts And Garnet-Bearing Xenoliths In Ordovician Bentonites, Barbara Bock

Geology Theses and Dissertations

Within outcrops of the black Utica shales south of the Mohawk Valley narrow re-entrants parallel with stratification are visible, often accompanied -by a marked orange-staining of the underlying strata. These rentrant features indicate the presence of bentonites weathered back faster then the enclosing shales. These bentonites are presumably magmatic ashes related to extensive volcanism when an island arc collided with the North American continent in the late Ordovician about 450 million years ago (Taconic orogeny).
Bentonites are good stratigraphic markers because of the short time-interval they represent and the large area they cover. Therefore they are commonly used as correlation …

Petrology And Major Element Geochemistry Of Basaltic Glasses From The Blanco Trough, Northeast Pacific, Glenn A. Gaetani

Geology Theses and Dissertations

The original electron microprobe analyses of suite of basaltic glasses recovered in 1968 by W.G. Melson and co-workers from the Blanco Trough have extremely unusual characteristics. Their compositions plot in a region of the normative Ol-Di-Pl-SiO2 tetrahedron which suggests that they represent liquids in equilibrium with an upper mantle assemblage of olivine + orthopyroxene at 10-15 kb. Given the present state of controversy surrounding the composition and depth of origin of primary MORB, natural examples of such liquids would be very important. The major element variations observed in the suite imply that the dominant phases are olivine and an iron-aluminum …

Application Of A Trace Element Fractionation Model To Cumulate Gabbroic Xenoliths Of Mauna Kea, Hawaii, Ulrike Eberle

Geology Theses and Dissertations

A trace element fractionation model originally designed to relate plutonic rocks containing a trapped glass component to a complementary volcanic rock suite was applied to olivine and opaque-oxide gabbroic xenoliths from the summit cone of Mauna Kea, Hawaii.
The mathematical model which is based on the Rayleigh Fractionation Law was extended to include the various phases present in these two groups of gabbros and was generalized to treat multiple trace elements, in this case four. These results were incorporated in a new FORTRAN program using the interval-bisection method to greatly improve the convergence time in the numerical solutions.
Calculated results …

Geology And Structure Of The Rocks Associated With The Basal (Madstone) Thrust Of The Josephine Ophiolite In Southwestern Oregon: Evidence For A Metamorphic Sole, Kristin A. Grady

Geology Theses and Dissertations

Many ophiolites have amphibolite at their base which contains a sharp inverted grade of metamorphism. These metamorphic soles are thought to have formed during the detachment and emplacement of the ophiolite. In addition to the sharp inverted grade of metamorphism, other characteristics of metamorphic soles include 1). a highly strained peridotite unit of the hanging wall which has concordant structures with underlying amphibolite and 2). an underlying melange sequence and continental rocks.
The Madstone thrust displaces the Josephine peridotite (Josephine ophiolite-162 Ma) onto amphibolites and underlying deformed gabbros of the Chetco Intrusive Complex. The rocks associated with the Madstone thrust …

Origin, Sedimentary Geochemistry, And Correlation Of Middle And Late Ordovician K-Bentonites: Constraints From Melt Inclusions And Zircon Morphology, Carsten Schirnick

Geology Theses and Dissertations

The present study of Paleozoic K-bentonites demonstrates that the geochemistry of melt inclusions and the morphology of zircons can be studied by inexpensive and simple-to-use methods, which rely on phenocrysts. Constraints are obtained that lead to (a) the origin of these altered volcanic ashes, (b) the geochemistry of ash-to-K-bentonite-alteration, and (c) the reliable correlation of extensively altered volcanic ashes (i.e. K-bentonites).
Silicic melt inclusions (i.e. non-devitrified) have been found in quartz and zircon phenocrysts contained within Ordovician and Devonian K-bentonites from New York State, the Upper Mississippi Valley, and Pennsylvania. Origin, source, and tectonic setting of the volcanism that produced …

Biological Markers In Lower Jurassic Synrift Lacustrine Black Shales, Hartford Basin, Connecticut, U.S.A., Michael A. Kruge, John F. Hubert, Jay F. Akes, Paul E. Meriney

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The East Berlin Formation (Lower Jurassic, Hartford basin, Connecticut, U.S.A.) is distinctive for its six cyclic units of lacustrine black shale and gray mudstone. separated by playa and fluvial redbeds. The black shales arc each about a meter thick and were deposited in subtropical, thermally stratified, oligomictic lakes, the youngest of which (lakes 3 through 6) were large enough to flood most of the basin and attained depths of several tens of meters.

The saturate fractions of solvent extracts of organic-rich black shales from each of the six lakes, collected at fresh roadcuts near East Berlin, arc dominated by extended …

Organic Geochemistry Of A Lower Jurassic Synrift Lacustrine Sequence, Hartford Basin, Connecticut, U.S.A., Michael A. Kruge, John F. Hubert, David F. Bensley, John C. Crelling, R Jay Akes, Paul E. Meriney

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Synrift terrestrial strata of the Lower Jurassic East Berlin Formation (Hartford basin, Connecticut, U.S.A.) record cyclical expansion and contraction of major lakes, six of which were deep enough to develop anoxic bottom waters. We have studied one representative lacustrine sequence in detail, sampling a new roadcut near the village of East Berlin. The section examined is 4 m thick, with a gray siltstone at the base, deposited in shallow water, overlain by an organic-rich black shale (deep water), succeeded in turn by another gray siltstone, deposited as the lake waters gradually receded. The upper gray siltstone is chemically distinct from …

Quaternary Geology Of The Chesapeake Bay, Jeffrey P. Halka, Steven M. Colman, Carl H. Hobbs Iii

VIMS Books and Book Chapters

The Chesapeake Bay, which is a classic coastal plain estuary, is located on a trailing edge continental margin. It has a surface area of nearly 6,000 km2 and ranges in width from 8 to 48 km. The morphology of the bay clearly reflects its formation as a response to fluctuating sea level during and following the last major continental glaciation. The shoreline is highly irregular, the tributaries form an intricate dendritic drainage pattern, and a deep axial channel occurs along much of its length (fig. 1). Water depths commonly exceed 30m in this deep channel, which is flanked by broad …

Postfolding Remagnetization That Passes The Fold Test, Russ R. Burmester, Myrl E. Beck Jr., D. R. Bazard

Geology Faculty Publications

The palaeomagnetism of folded Cretaceous redbeds in the Methow-Pasayten belt of Washington was studied in an attempt to resolve the tilt versus translation origin of shallow inclinations found in most Cretaceous plutonic rocks of the Pacific Northwest. After elimination of results from apparently strained, overturned beds, correction to palaeohorizontal of the high-temperature, dominant components produced two distinct directions, one from each of two areas. Treated separately, the magnetizations from these two areas appear to pass the fold test. Both directions are anomalously shallow which is typical of the region, but the discrepancy between them casts doubt that both could have …

Middle Eocene Foraminifera From The Piney Point Formation Of The Virginia And Maryland Coastal Plain, Megan S. Jones

OES Theses and Dissertations

This study examines the foraminiferal fauna, both benthic and planktonic, of the outcropping (45 samples) and subsurface (31 samples) middle Eocene Piney Point Formation in Virginia and Maryland. The primary objective of this study is to further refine the depositional history of the Salisbury Embayment which is represented by the middle Eocene Piney Point Formation. Ninety-six species of benthic and planktonic foraminifera were identified in this study. Of these, several are characteristic of the middle Eocene: Asterigerina texana, Hanzawaia danvillensis, Ceratobulimina exima, Cibicides westi, Chiloguembelitria columbiana, C. stavensis, Testacarinata inconspicua and Pseudohastigerina wilcoxensislmicra. While these were relatively abundant, diagnostic middle …

Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox

Journal of the Department of Agriculture, Western Australia, Series 4

Shallow interceptor drains can reduce waterlogging on sloping sites. Such drains will more than pay for themselves from the increased crop yield. Recent work has shown that these drains also decrease salinity so that they are cost-effective in the long as well as the short term.

Hydrostratigraphy And Groundwater Flow In The Sumas Area, Whatcom County, Washington, Sue Culton Kahle

WWU Graduate School Collection

Three types of groundwater systems occur within glacial sediments in a 10 mi² (25 km²) area near Sumas, Washington: an unconfined sand and gravel aquifer, a confined sand and gravel aquifer, and a generally unproductive clay aquitard. Water levels in the area were mapped from measurements of wells and points along stream courses in October 1988 and March 1989. The water-level configurations for the two aquifers roughly parallel surface topography. Water level maps were used to estimate direction of groundwater flow, which is generally to the southeast in the unconfined aquifer and to the northeast in the …

Danian (Paleocene) Molluscan Paleoecology In The Aftermath Of The Cretaceous-Tertiary Extinctions, East-Central Texas, Benjamin R. Farrell

WWU Graduate School Collection

Danian shelf sediments from the Brazos River region of east-central Texas span approximately the first two million years after the Cretaceous-Tertiary (K-T) extinctions with only minor changes in lithofacies. Study of these virtually continuous stratigraphic sections reveals the nature and timing of the molluscan faunal rebound in the wake of the K- T extinction event. Diverse Late Maastrichtian molluscan faunas were dominated by epifaunal suspension-feeders, primarily oysters. Immediately above the K-T extinction horizon, low-diversity molluscan assemblages were characterized by a bloom in the abundance of the pelagic herbivore family Litiopidae, which were rapidly replaced by a low diversity assemblage dominated …

Cross-Shore And Longshore Sediment Size Distribution On Southern Currituck Spit, North Carolina, Lauro Julio Calliari

Dissertations, Theses, and Masters Projects

Using Q-mode factor analysis, 87 surficial sediment samples collected from Duck and Whalehead beach, North Carolina, were analyzed using the weight percent of the gravel and sand fraction subdivided at 0.5 phi class interval as variables. An additional data set composed of 178 surficial sediment samples from Duck beach (bimodal) and Coquina beach (unimodal fine) representing three years of sampling at monthly intervals were analyzed by the same technique using only the sand fraction. The spatial and temporal patterns of sediment factor groups support three main inferences. (1) Bimodal beaches display a more distinct sediment zonation than unimodal beaches. (2) …
