A Monograph Of The Genus Polyphylla Harris In America North Of Mexico (Coleoptera: Scarabaeidae: Melolonthinae), Ronald M. Young

Bulletin of the University of Nebraska State Museum (1924–2023)

The North American species of the genus Polyphylla Harris, 1841, are defined and revised for the first time since Fall (1928). All name bearing types were examined except those of P. oklahomensis Hatch and P. subvittata LeConte (synonyms of P. hammondl), which are lost. A lectotype is designated for P. gracilis Horn, and neotypes for P. decemlineata (Say), P. occidentalis (L.), and P. variolosa (Hentz). New synonyms of P. decemlineata are P. comstockiana von Bloeker, P. matrona Casey, and P. potsiana Casey. New synonyms of P. crinita …

Discrimination Of Subparallel Beach Ridges Using Detrital Ilmenite Composition And Fourier Shape Analysis, Allen E. Evans Jr.

OES Theses and Dissertations

Elemental composition (Fe, Ti, Mn, Mg, V, Cu, Ni, Zn, and Cr) and Fourier shape analysis of magnetically separated detrital ilmenite from seven Pleistocene and modern beach sand deposits of the Southeastern Virginia Coastal Plain were used to distinguish each deposit. Geomorphic expression, crosscutting relationships and proximity to the present shoreline differentiates the relative age of the seven sampled beach deposits. Analysis of ilmenite elemental composition, independent of geomorphic expression, distinguished beach sands of

different age and was successful in determining that each beach contained ilmenite similar in composition. Of the seven beach ridges tested, subtle yet significant differences in …

Lacustrine Deltaic Deposits Of The Sandstone Tongue Of The Wasatch Formation, Fossil Basin, Wyoming, F. Steve Petersen

Loma Linda University Electronic Theses, Dissertations & Projects

Sedimentary structures and facies relations of the sandstone tongue of the Wasatch Formation in Fossil Basin, Wyoming are interpreted as indicative of a rapidly prograding bird's foot delta. Two upward coarsening siliciclastic sequences that contain bottomset, foreset, and topset beds were studied over an area of approximately 400 square kilometers. Vertical and lateral sedimentary changes within this sequence were documented by the measurement and study of over 35 stratigraphic sections. High and low angle cross-bedded sandstone units within the siliciclastic sequences thicken northward significantly before rapidly thinning and grading into the lacustrine Green River Formation. Field observations. lateral correlation of …

Paleoenvironments Of The Eocene Green River Formation (Laney Member) In The Anvil Wash Area, Southwestern Wyoming, M. Elaine Graham-Kennedy

Loma Linda University Electronic Theses, Dissertations & Projects

The study of abundant conchostracans in the Laney Member of the Green River Formation, Wyoming, has contributed to the resolution of the controversy over the depositional environment of finely laminated sediments. Conchostracans that typically live in ephemeral pools, pulmonate gastropods that require oxygenated water and freshwater ostracods indicate deposition of finely laminated sediments in a well oxygenated, shallow, freshwater lake. Mineralogical evidence indicating that Lake Gosiute was primarily fresh during deposition of the upper portion of the Laney Member includes predominance of calcite over dolomite and the clay composition of diagenetically altered tuffs. The minor amount of dolomite is detrital …

Lithologic Controls On Karst Groundwater Flow, Lost River Groundwater Basin, Warren County, Kentucky, Christopher Groves

Masters Theses & Specialist Projects

The Lost River Groundwater Drainage Basin in Warren County, Kentucky, is a karst drainage system encompassing 55 square miles (143 square kilometers) developed within the Mississippian St. Louis and Ste. Genevieve Limestones. Near the contact between these two formations are two bedded chert units, the Lost River Chert Bed (Elrod, 1899) within the Ste. Genevieve and the Corydon Chert Member (Woodson, 1983) of the St. Louis, which appear to be perching layers to shallow karst groundwater flow. Groundwater may be seen flowing on top of these beds in various cave streams and at swallets and springs throughout the basin.

Granitic Pegmatites In The Southeastern Adirondacks: Their Use As Indicators Of Temperature, Pressure, And Fluid Conditions During A Late Stage Of The Grenville Orogeny, John P. Mihalich

Geology Theses and Dissertations

Granitic pegmatites associated with the Grenville orogeny intrude a mid-Proterozoic, upper amphibolite to near granulite facies terrane in the southeastern Adirondack Mountains of New York State. The inferred anatectic, fluid-saturated, and minimum melt characteristics of the pegmatites suggest that they can be used as analogs of the "granite" or "haplogranite" system, and as indicators of crustal temperature, pressure, and fluid conditions during a late stage of the Grenville orogeny. Bulk chemical compositions of seven simple, undeformed pegmatites in the southeastern Adirondacks indicate that they are generally depleted in silica and sodium, and enriched in potassium, relative to experimental data on …

Textural And Lithologic Differences Of Cretaceous, Tertiary, And Quaternary Gravels Of South Arkansas, Lesli Wood

Journal of the Arkansas Academy of Science

Stream gravels have been derived from the Ouachita Mountains since at least Cretaceous times. Past studies have assigned ages to gravel deposits in the basins of the Saline and Little Missouri Rivers on the basis of altitude above local floodplains. This study examines the lithologies and textures of seven gravel outcrops ranging in age from Cretaceous to Quaternary to determine whether any patterns of variation based on assigned ages, variable sources, or precise depositional setting can be discerned. No variation patterns could be found for size distributions of sand-sized and larger fractions. However, the amount of silt-clay matrix decreases through …

Karstification Of The Pennyroyal Plain Behind The Retreating Chester Escarpment: Warren, Simpson & Logan Counties, Kentucky, Anthony Able

Masters Theses & Specialist Projects

Hydrogeologic investigations were conducted on the drainage systems of an area of the Pennyroyal sinkhole plain of south central Kentucky. The degree of karstification of five area streams was studied to develop an understanding of the evolution of drainage as the landscape changes from a sandstone caprock plateau to a limestone sinkhole plain. The Chester Upland, capped by the Big Clifty Sandstone, possesses predominantly surface drainage and the Pennyroyal Plain, formed on Mississippian limestones, possesses considerable subsurface drainage. As the Chester Upland Escarpment retreats and surface streams are onto the limestones, the streams evolve to become subsurface streams. The five …

Slack-Water Deposits And The Magnitude And Frequency Of Flash Floods, Eastern Kentucky, Russell G. Shepherd, Lisa K. Bienkowski

KWRRI Research Reports

The potential for predicting flood magnitude and frequency using sediments deposited in backwater areas during flash floods was investigated on the Cumberland Plateau of eastern Kentucky, a region n9torious for flash flooding. Slack-water deposits are abundant in the area at tributary mouths and bedrock channel expansions. They are identifiable on geologic quandrangle maps, and are locally good potential indicators of maximum flood-crest elevations. However, in this humid region, flash floods could not be distinguished from non-flash floods using slack-water sedimentology.

The results from the slack-water deposits studied indicate that they offer limited potential for predicting flash floods because 1) intense …
