Petrology Of The Middle Cambrian Blacksmith Formation, Southeastern Idaho And Northernmost Utah, David Paul Zelazek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Blacksmith Formation of Middle Cambrian (Albertan) age was studied in southeastern Idaho and northernmost Utah. Lithology and sedimentary structures were compared with modern environments and ancient rocks to determine environments of deposition, paleo-geography, diagenetic alterations and patterns of dolomitization.

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 …

Mineralogy And Petrology Of Lava Flows (Tertiary-Quaternary) In Southeastern Idaho And At Black Mountain, Rich County, Utah, Barbara J. Puchy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lava flows of Tertiary-Quaternary age occur in Enoch Valley, Upper Valley, and Slug Valley in southeastern Idaho. The basalts in Upper Valley and Enoch Valley contain olivine (Fo₆₉ to Fo₃₇), plagioclase (An₆₂ to An₃₉), augite and Fe-Ti oxides. The lava in Slug Valley lacks plagioclase, but contains sanidine (Or₇₀ to Or₅₆) with a trace of biotite and amphibole, and thus, has been termed alkali trachyte.

Black Mountain, on the eastern side of Bear Lake, northeastern Utah, is capped by basalt. Minerals present include olivine (Fo₈₃ to Fo₇₂), plagioclase …

Petrology Of The Arumbera Sandstone, Late Proterozoic(?) - Early Cambrian, Northeastern Amadeus Basin, Central Australia, Keith T. Conrad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Arumbera Sandstone forms distinctive strike ridges with dark reddish slopes and orange-white cliffs throughout most of the northeastern Amadeus Basin. It is divisible into four readily mappable informal units. The ridge-forming units, 2 and 4, are divided into three and two subunits, respectively.

Unit 1, Subunit 2b, Unit 3 and Subunit 4b are generally comprised of recessive, pale-red to grayish-red, medium- to thin-bedded, fineto medium-grained arkose with major proportions of siltstone and mudshale. These sedimentary bodies are interpreted as a complex system of coastal to nearshore-marine environments including tidal flats, tidal channels, estuaries and beaches. Evidence includes: (1) predominance …

Shallow Electromagnetic Data From Three Known Fault Zones In The Paradox Basin, Utah, Raymond D. Watts, U.S. Geological Survey

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

This report describes a preliminary investigation of the effectiveness of two electromagnetic exploration methods as means of finding unmapped faults in the Paradox Basin environment. Results indicate that the Very Low Frequency (VLF method is useful. VLF profiles were measured across three known fault traces near Gibson Dome, San Juan County, Utah. Each fault or set of faults generated a significant anomaly. In some cases, the anomaly due to the fault was superimposed on a larger scale anomaly caused by the transition from unaltered rocks away from the fault to altered rocks in or on one side of the fault …

Off-Road Vehicular Destabilization Of Hillslopes: The Major Contributing Factor To Destructive Debris Flows In Ogden, Utah, 1979, John K. Nakata

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

A severe rain storm on August 11 and 18, 1979, caused major flood damage in urban areas of east Ogden, Utah. At least 3.85 cm of rain fell in a 7 hour-period. The severity of damage was dramatically increased by water diverted from the Brigham-Ogden Canal, when it was clogged by a debris flow in the vicinity or Third, Taylor, and Polk Streets (Fig. 1). The purpose or this investigation is to ascertain the sequence of events that followed the storm, and to quantify the processes insofar as possible. An inspection of the area on September 21-25, 1979 , and …

Altered Volcanic Ash Partings In The C Coal Bed, Ferron Sandstone Member Of The Mancos Shale, Emery County, Utah, United States Geological Survey

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

When volcanic ash falls onto the surface of a peat-forming swamp and is then covered by peat, it forms a horlzontal parting that can be recognized in the subsequent coal bed. As a consequence of the acid leaching environment in the swamp, the original glassy component and some of the less resistant pyrogenic minerals in the ash alter to clay minerals, usually kaolinite.

Hydrology Of The Ferron Sandstone Aquifer And Effects Of Proposed Surface-Coal Mining In Castle Valley, Utah, Gregory C. Lines, Daniel J. Morrissey, Thomas A. Ryer, Richard H. Fuller, U.S. Geological Survey

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

Coal in the Ferron Sandstone Member of the Mancos Shale of Cretaceous age has traditionally been mined by underground techniques in the Emery Coal Field in the southern end of Castle Valley in east-central Utah. However, approximately 99 million tons are recoverable by surface mining. Ground water in the Ferron is the sole source of supply for the town of Emery, but the aquifer is essentially untapped outside the Emery area. The Ferron Sandstone Member crops out along the eastern edge of Castle Valley and generally dips 2" to 10" to the northwest beneath the surface. Sandstones in the Ferron …

Application Of Mineral-Solution Equilibria To The Search For Sanstone-Type Uranium Deposits In The Beaver Basin, Utah, W. R. Miller, J. B. Mchugh, U.S. Geological Survey

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

An improved computer modeling program was used to calculate the saturation indexes of 50 waters from the Beaver basin in west-central Utah with respect to uraninite and coffinite. The mineral-solution study showed that the chemical environment of parts of the Beaver basin is favorable for the occurrence of sandstone-type uranium deposits. The ground waters from several areas are supersaturated with respect to uraninite and coffinite. Two areas, in particular, an area west of the town of Beaver and an area near the settlement of Manderfield, have been identified as most favorable for exploration. The methods described in this study can …
