Geology Of The Southwestern Part Of The Randolph Quadrangle, Utah-Wyoming, Steven C. Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A detailed study of the southwestern part of the Randolph quadrangle was undertaken in view of the fact that Richardson (1941) mapped a large area of undifferentiated Ordovician rock. Therefore, the purposes of this investigation are: (1) to prepare a more detailed geologic map of the south­western part of the Randolph quadrangle (Plate 1), (2) to describe the struc­ture, stratigraphy, and geologic history of the area, and (3) to relate the geology to adjacent areas.

Geomorphic Features And History Of The Lower Part Of Logan Canyon, Utah, Edmund J. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Logan Canyon is located east of Logan, Utah, in the Bear River Range. The lower part of Logan Canyon is considered that section of the canyon from its mouth upstream to Tony Grove Canyon, a distance of 22 miles¹, Figure 1. Some tributary canyons of the lower part of Logan Canyon have been included in this investigation because of their relationship to Logan Canyon. Grassy Flat Canyon, a south tributary of Logan Canyon 4.4 miles from Logan, exhibits several geomorphic features related to the geology of Logan Canyon. Because of its extensive use and close association with Logan …

Slope Deposits Of The Pennsylvanian Haymond Formation, Marathon Region, Texas, Walter E. Dean Jr.

Earth and Planetary Sciences ETDs

The Haymond Formation of the Marathon basin, Texas consists mainly of a sequence of more than 12,000 siltstone-shale couplets which, combined with the similar couplets of the older Tesnus Formation, form a sequence of "flysch" sediments more than 10,000 feet thick deposited on the eastern slope of the subsiding Llanoria geosyncline. The Haymond Formation contains no diagnostic fossils; its age is known only as Lower Pennsylvanian, probably Atokan.

Variation In Perthitic Microcline From A Zoned Pegmatite, Terry E. Tullis

Journal of the Minnesota Academy of Science

Quantitative microscopic and chemical anaylses of 12 specimens of microcline, most of them perthitic, from the zoned Hugo pegmatite in the Black Hills near Keystone, South Dakota, have yielded data that can be used to estimate the temperatures of crystallization at successive stages in the formation of the pegmatite. The determined temperatures of crystallization range from 565°C in zone 3a, near the margin of the pegmatite, to 280°C in zone 7, the core.

Nature And Lateral Variation Of Lost Rock Limestone In The Tri-State Zinc-Lead District., Adnan A. Saadallah

Masters Theses

"The nature and lateral variation of a host rock limestone in the Tri-State zinc-lead district were petrographically studied within a single horizon, the M bed. This bed is a massive crinoidal limestone in the Tri- State district of southwestern Missouri, northeastern Oklahoma and southeastern Kansas and is a part of the Mississippian Keokuk Formation.

One hundred and twenty specimens from this bed were collected underground from six pull drifts in five mines: West Side, Grace B, Big John, Little Greenback, and Mudd Mines. The specimens were collected at regular intervals, usually ten to twenty feet, beginning at the edge of …

Structural And Magnetic Characteristics Of The Belton Anomaly, Cass County, Missouri, Nagib Chamon

Masters Theses

"A vertical intensity magnetic survey of approximately 156 square miles in Cass County, central-west Missouri, revealed a broad circular anomaly whose magnetic relief exceeds 1000 gammas. Surface rocks are very gently inclined and are of Pennsylvanian age. Crystalline basement rocks are at a depth of approximately 2400 feet. Analysis of the data shows that the Belton anomaly consists of discontinuous smaller magnetic anomalies surrounding the central part of this broad anomaly. The central area of the Belton anomaly is occupied by a magnetic low. Analytical calculation showed that the source of the magnetic disturbance is at least 3650 feet below …

Petrology And Mineralogy Of Certain Portions Of The Fredericktown Deposits, Farouk El Baz

Doctoral Dissertations

"The Fredericktown area is part of the 'Lead Belt' district of southeastern Missouri, the major lead-producing region in the world for fifty years. The district is a typical example of the Mississippi Valley Type deposits. The ores occur in Upper Cambrian sediments overlying Precambrian rocks.

The Fe-Cu-Pb-Zn (-Co-Ni) - sulphide deposits of Fredericktown occur over a few square kilometers in sediments overlying two 'granite knobs'. The sedimentary units lap upon and pinch-out against these buried basement hills.

The basal sedimentary unit, the Lamotte Formation, is a time-transgressive, marine, submature orthoquartzite. It contains a Boulder Bed at the base or at …

Lower Paleozoic Chitinozoans And Scolecodents From North Dakota, Douglass H. Morgan

Theses and Dissertations

Chips from cores of the Red River and Stony Mountain Formations of Ordovician age and the Dawson Bay Formation of Devonian age in North Dakota were taken at three-foot intervals, dissolved in acid, and the residue examined for insoluble, pseudochitinous microfossils. Chitinozoa, an extinct order of rhizopod protozoans, were found in abundance along with lesser numbers of scolecodonts, the mouth parts of polychaete worms. Because the study was restricted to the core available at the North Dakota Geological Survey, which rarely included complete sections of the formations, a complete picture of the distribution of these forms must await the more …

The Physical Limnology And Sedimentology Of Miller Lake, Martin River Glacier, South-Central Alaska, Edward Callender

Theses and Dissertations

Miller Lake is an ice-walled lake located on the terminus of the Martin River Glacier, south-central Alaska. It has an area of 1.36 km² and a mean depth of 25 meters. The lake basin was formed by the coalescence of several ice sinkholes and is characterized by extremely uneven bottom topography.

Analysis of detailed thermal data obtained during the summer of 1963 indicates that the lake is never permanently thermally stratified but does develop some stratification during periods of warm, calm weather. This stratification is easily destroyed by stormy weather. Miller Lake is classified as a subpolar lake due …

The Geology Of Eastern Wells County, North Dakota, Ronald J. Kresl

Theses and Dissertations

Late Wisconsinan (Pleistocene) glaciation was responsible for the varied landforms of eastern Wells County. The Burnstad-Streeter phase advanced from the north-northeast about 10,000 to 12,000 years ago and was obstructed by the elevated Missouri Coteau which caused basal shearing and subsequent movement of subglacial drift into the ice. As this ice stagnated, the resultant drift cover impeded ablation and insulated the waters of superglacial lakes present on the surface of the Coteau at that time. Abundant Pleistocene fossils have been found in the sediments of these former lakes. Upon complete ablation, characteristic dead-ice features resulted on the surface of the …

Glacial Geology Of Western Wells County, North Dakota, George A. Faigle

Theses and Dissertations

The landforms of western Wells County were formed during late Wisconsinan glacial activity. Because of the relatively dry climate they have been modified only slightly by post-glacial erosion and mass wasting.

The southern one-third of the area is characterized by randomly-oriented mounds of till or dead-ice moraine. The dead-ice moraine originated when a large mass of stagnant ice ablated after typical glacial depositional features had formed on its drift-covered surface. Complete ablation of the ice resulted in the collapse of the previously formed features.

The remaining two-thirds of the area is characterized by and moraine, ground moraine, outwash, and meltwater …

The Glacial Geology Of Eastern Sheridan County, North Dakota, Thomas C. Gustavson

Theses and Dissertations

During late Pleistocene time two ice advances affected parts of eastern Sheridan County, North Dakota. The first advance deposited the Burnstad, Streeter and Grace City drifts, and covered the whole county. The second advance deposited the Martin drift and occupied only the northern quarter of the county.

The Streeter drift, characterize by dead-ice landforms and nonintegrated drainage, is separated from the Burnstad drift by a large partly collapsed outwash plain on the distal side of a pronounced ground moraine and poorly integrated drainage, is separated from the Streeter drift by the Lincoln Valley and moraine and the Missouri Coteau escarpment. …
