Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert
Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert
Theses and Dissertations
Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

A Petrographic And Spectrographic Analysis Of Several Soapstone Artifacts From Tennessee And Soapstone Deposits In North Carolina And South Carolina: In An Attempt To Determine The Source Area Of The Artifacts, Earl Roger Bohanan
Masters Theses
Several soapstone artifacts from Late Archaic-Early Woodland archaeological sites in Tennessee and ten soapstone deposits, two in South Carolina and eight in North Carolina were analyzed by X-ray diffraction, X-ray spectroscopy and petrographically in an attempt to correlate the artifacts and deposits. The data show that two of the deposits, Shelton Mine and Watermellon Branch, exhibit the best correlation with some of the artifacts. However, the evidence isn't conclusive.
Petrographic analysis revealed that the deposits and artifacts consist of one of two distinct mineral assemblages, one consisting of talc, chlorite, and anthophyllite, and a second in which talc, chlorite, and …

A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin
A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum
A new species of Pliocene peccary, Prosthennops (Macrogens) graffhami; is described from the Kimball Formation, Ogallala Group, Frontier County, Nebraska. This new species is the latest in geologic age and most advanced in the genus.
The remains of fossil vertebrates are generally rare in the upper part of the Ogallala group, and some have maintained that Hemphillian faunas such as Coffee Ranch and Smith County, Kansas, represent the latest Ogallala faunas. Later faunas than are typically considered as Hemphillian, containing more advanced forms, occur in the Kimball Formation and deposits of equivalent age. Known faunas which may …

Conifer Wood From The Upper Jurassic Of Utah; I, Xenoxylon Morrisonense Sp. Nov., William D. Tidwell, David A. Medlyn
Faculty Publications
A new species of conifer wood, Xenoxylon morrisonense, is described from the Morrison Formation on the Colorado Plateau. It is compared with other species of Xenoxylon, with X. latiporosum being the closest. Xenoxylon morrisonense differs from X. latiporosum in its marked indentations, simple pits on the horizontal and tangential walls of ray cells, absence of crassulae, presence of wood parenchyma, and thin borders on podocarpoid type crossfield pits. The origin of the septa in the tracheids is summarized, and the possible affinity of Xenoxylon with the Podocarpaceae is considered.

Bulletin of the University of Nebraska State Museum
"Machairodus catocopis Cope" is shown to be a pseudaelurin cat belonging to the genus Nimravides Kitts. Nimravides thinobates (Macdonald) is a possible synonym of N. catocopis (Cope). Nimravides is compared with the Eurasian Machairodus-like cat, Dinofelis. Machairodus (Heterofelis) coloradensis is reported from the Kimball Formation, upper Pliocene (Kimballian) of Cheyenne County, Nebraska, and from the upper part of the Ash Hollow Formation, Pliocene (Hemphillian) of Sherman County, Nebraska. The Kimballian form is described as a new subspecies, Machairodus coloradensis tanneri.
The genus Machairodus has long been associated with the Hemphillian of North America and the …
Structural Studies In The Moretown And Cram Hill Units Near Ludlow, Vermont, William J. Gregg
Structural Studies In The Moretown And Cram Hill Units Near Ludlow, Vermont, William J. Gregg
Geology Theses and Dissertations
The geology of the eastern limb of the Green Mountain Anticlinorium consists of a series of Paleozoic metasedimentary rocks with lithologic boundaries arranged in a remarkably straight trend approximately parallel to the axis of the Green Mountains. Published reports of the area, consisting largely of reconnaissance mapping, have treated this complex series of polyphase deformed rocks as an essentially upright autocthonous sedimentary sequence. Boundaries between rock units have, for the most part, been assumed to be primary in origin, as have various structural elements within the rock units. More recent work in selected areas within the Ludlow Quadrangle has revealed …

A Study Of Some Petrologic And Structural Aspects Of The East Dover Ultramafic Bodies, South Central Vermont, Mark Allen Hoffman
Geology Theses and Dissertations
INTRODUCTION (pp.1-4)
Mineralogical, textural and chemical changes of ultramafic rocks in response to regional deformation and metamorphism are, at best, imperfectly known (Miyashiro, 1973, p. 30). In Vermont, which has an extremely prominent and well-exposed belt of ultramafics (fig. 1), investigation of these rocks has largely been directed toward such processes as serpentinization, steatitization, and the formation of metasomatic zones at the contacts with country rocks. With few exceptions, there is a lack of detailed descriptions of regional metamorphic textures, mineralogy, and structures developed in the Vermont ultramafic rocks. It is the main purpose of this thesis to describe the …
Holocene Stratigraphy And Chronology Of Mountain Meadows, Sierra Nevada, California, Spencer H. Wood
Holocene Stratigraphy And Chronology Of Mountain Meadows, Sierra Nevada, California, Spencer H. Wood
Spencer H. Wood
Valley-fill deposits, exposed by Twentieth-Century dissection of a number of meadows on the west slope of the southern Sierra Nevada, contain a stratigraphic record strongly affected by secular variations in watershed hydrology during the Holocene. Meadows are situated in low gradient reaches, adaquately supported by seep-age water, where fine textured materials accumulate under present hydrologic conditions• Meadows do not necessarily owe their origin to glacial modification of drainage. Many meadows have formed in both glaciated and unglaciated valleys by a water table rise in valley-fill deposits. Ground water in any meadow drainage basin is annually recharged by snowmelt. Significant evapotranspiration …

Middle And Late Cenozoic Tapirs From Nebraska, C. Bertrand Schultz, Larry D. Martin, R. George Corner
Middle And Late Cenozoic Tapirs From Nebraska, C. Bertrand Schultz, Larry D. Martin, R. George Corner
Bulletin of the University of Nebraska State Museum
The distribution and evolution of Late Cenozoic tapirs are discussed and the forms present in Nebraska are reported. Two new species are described from the Ogallala Pliocene of Nebraska, ?Tapirus johnsoni and ?T. simpsoni. Tapirs are known in Nebraska from the Early Oligocene through the Middle Pleistocene. The northern limit of the distribution of the tapirs contracts gradually southward in North America throughout the Tertiary, and even during the Pleistocene interglacials Nebraska must have been near the northern limit of their range.

Problems In Interpreting Unusually Large Burrows, Richard G. Bromley, H. Allen Curran, Robert W. Frey, Raymond C. Gutschick, Lee J. Suttner
Problems In Interpreting Unusually Large Burrows, Richard G. Bromley, H. Allen Curran, Robert W. Frey, Raymond C. Gutschick, Lee J. Suttner
Geosciences: Faculty Publications
Although marine burrows of unusually large dimensions have long been known in certain areas, they are probably much more widespread in the rock record than is generally recognized. Such burrows constitute a heterogeneous group, having little in common other than "exceptional" size. Yet their size alone unites them in difficulty of interpretation: e.g., densely spaced-dwelling burrows of combined dwelling-escape burrows as much as 12 cm in diameter and 5 m long; vertical dwelling burrows only 0.5 cm in diameter but up to 9 m long; possible escape structures as much as 24 cm in diameter and 3 m long, subsequently …
Stratigraphic Occurrences Of Teleoceras With A New Kimballianspecies From Nebraska, Lloyd G. Tanner
Stratigraphic Occurrences Of Teleoceras With A New Kimballianspecies From Nebraska, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum
Study of Teleoceras remains in the University of Nebraska State Museum indicates that this specialized, short-limbed rhinoceros inhabited the Central Great Plains from Early through Late Pliocene. Previously thought to have become extinct at the end of the middle Pliocene, this genus is now known from the very latest Pliocene. A new species, Teleoceras schultzi, is described from the Kimball Formation, Ogallala Group, Frontier County, Nebraska.
A One-Dimensional Mathematical Model Of Tidal Hydraulics And Salt Intrusion In Estuarine Rivers, Fwu-Ding Lin
A One-Dimensional Mathematical Model Of Tidal Hydraulics And Salt Intrusion In Estuarine Rivers, Fwu-Ding Lin
Dissertations, Theses, and Masters Projects
A one-dimensional mathematical model has been developed as a practical way to analyze the tidal wave propagation and its interaction with freshwater runoff. The model approaches the problem both theoretically and numerically. To develop this model, the one-dimensional hydrodynamic and salt-balance equations are derived by integrating the three-dimensional equations over the cross section. These differential equations are approximated with implicit finite difference forms and the tidal heights, currents and salinity distributions are solved by using digital computer CDC 6400. The model has been applied to the James River in two different cases: the normal case and hurricane case. Because of …

Paleomagnetism Of The San Juan Volcanic Field, Southwestern Colorado, Steven Douglas Sheriff
Paleomagnetism Of The San Juan Volcanic Field, Southwestern Colorado, Steven Douglas Sheriff
WWU Graduate School Collection
Geologic Setting
The San Juan volcanic field of southwestern Colorado consists of 2.5 X 104 km2 of volcanic rocks ranging in age from early Oligocene to Pliocene. Major volcanic activity in the San Juan field began about 35 million years ago with widespread eruption of rhyodacitic to andesitic lavas from scattered volcanic centers (Lipman and others, 1970). This type of volcanism peaked about 33 million years ago and then began to decline. About 30 million years ago, volcanic activity once again increased in the area. This time the eruptions were ash flows of intermediate to felsic composition. The …
