It has higher alkali, total iron, and titanium contents that Unit 1 basalt. Unit 1 basalt is similar …

Nonpoint Source Transport Model For Indicator Bacteria From Western Rangeland Watersheds, Everett P. Springer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grazing is a primary land use in much of the western United States, but little is known about grazing impacts on water quality. The most sensitive water quality indicators of grazing are the fecal indicator bacteria. The objective of this study was to develop a general transport model describing the movement of fecal indicator bacteria from upland sources to channel systems.

Model development was done using simulated rainfall and a runoff surface 30.48 m by 1.83 m.

Initially the runoff surface was smooth concrete and was used to examine the effects of distance from the outlet on coliform counts by …

Chemical Changes In Groundwater Of Northern Utah Valley, Utah, Paul E. Fairbanks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Northern Utah Valley is one of the fastest growing areas of Utah and has increasing needs for domestic, industrial, and agricultural water.

Genesis Of A Vertisol And An Associated Palexeroll In Northern Utah, Robert C. Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The genetic relationship between a Vertisol and an associated Mollisol with an argillic horizon was studied. These soils are taxadjuncts of the Hawkins and Ostler series, respectively. They occur in the Wasatch Mountains of northern Utah and have similar parent materials, altitudes, and slope percentages. Ostler soils have a dense cover of Gambel oak (Quercus gambelii) and occur preferentially on north aspects. Mule's ear (Wyethia amplexicaulis) is the dominant vegetation on Hawkins soils, which are most frequent on south aspects. Erosion is prevalent on Hawkins soils because the mule's ear does not adequately cover the soil …

Petrology Of The Middle Cambrian Blacksmith Formation, North-Central Utah, Howard William Hay Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dolostones and dolomitic limestones of the Middle Cambrian Blacksmith Formation were studied in the Bear River and Malad Ranges and the Wellsville Mountains of north-central Utah.

Use Of Multispectral Scanner Images For Assessment Of Hydrothermal Alteration In The Marysvale, Utah, Mining Area, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

Multispectral images of an area near Marysvale, Utah, were collected by using the airborne U.S. National Aeronautics and Space Administration (NASA) 24-channel Bendix multispectral scanner; they were analyzed to define areas of hydrothermally altered, potentially mineralized rocks. Hydrothermally altered rocks, particularly volcanic rocks affected by solutions rich in sulfuric acid, are commonly characterized by concentrations of argillic minerals such as alunite and kaolinite. These minerals are important for identifying hydrothermally altered rocks in multispectral images because they have an intense absorption band centered near a wavelength of 2.2 um. Unaltered volcanic rocks commonly lack these minerals and hence do not …

The Blacksmith Formation can be divided into five basic rock types. Rock type A has cryptalgalaminae, mudcracks, and lacks bioturbation. Rock type A is inferred to have been deposited in the upper intertidal to supratidal environment. Rock type B is extremely dolomitized and brecciated. It is inferred that rock type B was deposited in the upper intertidal to supratidal environment. …

Faunal Succession And Depositional Environments Within The Lodgepole Limestone (Early Mississippian) Of Samaria Mountain, Idaho, Gary Keith Hines

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Community succession, the orderly changes a community experiences with time, is considered to be the result of either autogenic or allogenic factors working singularly or in combination. It has been further suggested that, as communities undergo succession, certain biological parameters change in a predictable manner. Examination of members 2 through 4 of the Mississippian (Kinderhook-Osage) Lodgepole Formation of Samaria Mountain, Idaho provides a means to evaluate these concepts.

Within the study section comprised of 125 beds (61.5 m thick), four rock types are recognized. These include: (1) fossiliferous wackestone (78% of beds), which ranges in color from dark-gray (N3) to …

Growth-Form Analysis And Paleoecology Of The Corals Of The Late Ordovician Through Mid-Silurian Fish Haven And Laketown Formations, Bear River Range, North-Central Utah, Thomas B. Rich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morphology of corals of the Late Ordovician through mid-Silurian Fish Haven and Laketown Formations were analyzed to document adaptations to inferred enviromental conditions, i.e., (bathymetry, illumination, sedimentation, currents, and energy), under which their enclosing sediment was deposited. Specimens and data were collected from six sites. Insoluble-residue tests were performed on the corals' matrices.

Individual corallites of radial-lensoidal corals radiate in all directions. Vertical growth, however, was restricted in turbulent conditions. Umbrellic, radial-lensoidal corals feature downward facing corallites, considered to be an adaptation to a well illuminated environment.

On tabular lensoidal corals, constituent corallites faces exclusively upward, an orientation needed under …
