A Five Parameter Study Of Spherical Transient Waves In A Generalized Voigt Model, Liang-Juan Tsay
A Five Parameter Study Of Spherical Transient Waves In A Generalized Voigt Model, Liang-Juan Tsay
Doctoral Dissertations
"Transient spherical waves in a generalized Voigt model were investigated in this study. Both Laplace and fourier transform solutions of the spherical wave equation for a generalized Voigt model were obtained by means of the correspondence principle. Laplace transform solutions were inverted numerically into the domain for the study of the characteristics of the wave forms, and Fourier transform solutions were utilized for the analysis of frequency dependency attenuation in the models. Generalized Voigt models A and B in which a dashpot is connected in series with spring and dashpot components were unable to represent a solid which would simulate …

Stratigraphy And Structure Of The Northwestern Guadalupe Mountains, New Mexico, Klyne Headley
Stratigraphy And Structure Of The Northwestern Guadalupe Mountains, New Mexico, Klyne Headley
Earth and Planetary Sciences ETDs
The northwestern Guadalupe Mountains of southeastern New Mexico are part of a large regional cuesta that slopes gently northeast. The crest of the northern escarpment rises abruptly to more than 2,200 feet above Pinon Valley.
The rugged west-facing escarpment has been carved in an uplifted fault block composed entirely of Permian sedimentary rocks having an aggregate thickness of about 1,700 feet. Dark-red to buff siltstone, gray dolomite, and white to gray gypsum compose the Yeso Formation. Conformably overlying these rocks is the dark-brown limestone and dolomite sequence of the San Andres Formation. The Glorieta Sandstone which usually occurs between these …

Facies Analysis; Fredericksburg Limestones; Callahan Divide, Texas, Andre Louis Boutte
LSU Historical Dissertations and Theses
During Fredericksburg (Early Cretaceous) time the entire Callahan Divide area of west-central Texas was the site of clayey, lime-mud accumulation in a normal-marine, shallow-shelf environment. Lateral homogeneity of the quiet-water environment was soon interrupted locally by the deposition of bioclastic lime-sands in a linear, highly agitated shoal-zone coinciding with a portion of the axis of a regional, positive, Paleozoic structural feature known as the Concho Arch. Localized shoal conditions persisted throughout most of Fredericksburg time and resulted in the deposition of a thick sequence of grainstones and packstones collectively referred to in this paper as the Callahan Complex. Numerous diastems …
Origin Of Reeflike Masses In The Upper Member Of The San Andres Formation, Central Guadalupe Mountains, Eddy County, New Mexico, Richard Lane Squires
Origin Of Reeflike Masses In The Upper Member Of The San Andres Formation, Central Guadalupe Mountains, Eddy County, New Mexico, Richard Lane Squires
Earth and Planetary Sciences ETDs
Several reeflike masses crop out in the upper part of the Upper member of the San Andres Formation in the Last Chance Canyon area, southeastern New Mexico. The reeflike masses are situated on the Northwest shelf adjacent to the Delaware basin of Permian age. Based on the compilation of the field and laboratory data, it was concluded that the reeflike masses are not reefs at all and such exposures are termed pseudoreefs. No criteria were found which could be used to differentiate the masses from surrounding, laterally equivalent strata since both consist of relatively unfossiliferous dolomitized mudstones and wackestones. The …

Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom
Bulletin of the University of Nebraska State Museum (1924–2023)
Biometrical study of morphology and development in a sample of 100 cranidia, 94 pygidia, 26 free cheeks, and 9 complete specimens of the trilobite Ameura sangamonensis (Meek and Worthen) from the Bonner Springs Shale (Pennsylvanian; Missouri Series) in eastern Nebraska indicates that the dominant growth pattern was isometric. Evidence supporting this conclusion consists of rectilinear size relations among eight pairs of cranidial dimensions, three pairs of pygidial dimensions, and three pairs of dimensions of the free cheeks. Qualitative changes in pygidial morphology during development include a progressive decrease in prominence of the border, increasing width of the posterior border relative …

Geology Of The Southern Pilot Range, Elko County, Nevada And Box Elder And Tooele Counties, Utah, John Michael O'Neill
Earth and Planetary Sciences ETDs
The southern Pilot Range is a slightly sinuous, north-trending mountain range located in the northeastern part of the Great Basin.
Approximately 18,500 feet of miogcosynclinal sedimentary rocks representing every system from late Precambrian to Permian(?) are exposed in the southern Pilot Range. Because of intense faulting, many of the stratigraphic relationships between the formations are impossible to determine. Mesozoic and Tertiary strata are absent; however, Pleistocene Lake Bonneville deposits are wide spread, although thinly distributed. Small igneous stocks, dikes, and sills are common only in the southern two-thirds of the map area. Stocks are principally granodioritic. In several cases the …

Lake Bonneville History In Cutler Dam Quadrangle, Cache And Box Elder Counties, Utah, G. Glayde Maw
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
When Lake Bonneville spilled through Red Rock Pass at the north end of Cache Valley, the major part of the lake in Salt Lake Valley had to drain from west-to-east through Cutler Dam Quadrangle. Here two major saddles connect the two valleys: (1) Bear River Narrows, at about +4380 feet; and (2) Cache Butte-Wellsville Mountain Pass 4.2 miles south, at about +4970 feet. Spillover levels at both places are cut into older rocks.
Only two morphostratigraphic units are recognized widely in the quadrangle. These represent high stands at the Bonneville level (+5180 ± 20 feet) and at the Provo level …
