Geology Of Southern Part Of The James Peak Quadrangle, Utah, Jan G. Blau

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mapped area, in north-central Utah, is centered about 22.6 miles south of Logan, Utah. It measures about 3.8 miles in the north-south direction and 6.6 miles in the east-west direction. Stratigraphic units of Precambrian and Cambrian age underline most of the area. The Precambrian units are as follows: (1) Maple Canyon Formation, (2) Kelley Canyon Formation, (3) Orthoquartzite unit, (4) Argillite unit, (5) Mutual Formation, and (6) Volcanic unit. The Brigham Formation, which overlies the Precambrian volcanic unit, is probably of Cambrian age; however, the lower part may be Precambrian. The overlying Cambrian carbonate unit is not differentiated. The …

Petrology Of The Upper Nounan - Worm Creek Sequence, Upper Cambrian Nounan And St. Charles Formations, Southeast Idaho, Lillian Donley Wakeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The upper member of the Nounan Formation and the Worm Creek Member of the St. Charles Formation, both late Cambrian in age, were studied in the Bear River Range and the Fish Creek Range in southeast Idaho. Lithology and sedimentary structures of these units were compared with characteristics of similar modern sediments and ancient rocks, to determine the environments of deposition and effects of diagenesis for the interval studied.

On the basis of widely traced marker horizons, the two-member interval is divided into three parts, with parts 1 and 2 comprising the upper member of the Nounan Formation, and part …

Structural Geology Of Eastern Part Of Richmond And Western Part Of Naomi Park Quadrangles, Utah-Idaho, Arthur J. Mendenhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mapped area, which includes the eastern part of the Richmond and the western part of the Naomi Peak quadrangles, Utah-Idaho, is located in the central part of northern Utah and southeastern Idaho. It is located along the eastern side of Cache Valley and western side of the Bear River Range. Cache Valley is in the Basin and Range province and the Bear River Range is in the Middle Rocky Mountain province. The mapped area is about 8.6 miles long, in the north-south direction, and 7.8 miles long, in the east-west direction.

The Mutual Formation of Precambrian age is the …

Structural Geology Of The Southern Part Of Clarkston Mountain, Malad Range, Utah, Wayland E. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mapped area, in north-central Utah, is located west of Clarkston, Utah. It includes the southern part of Clarkston Mountain and part of the Junction Hills, which extend southward from Clarkston Mountain. The area is represented on the southeastern part of the Portage quadrangle, Utah-Idaho, and the southwestern part of the Clarkston quadrangle, Utah-Idaho. It measures about 8.3 miles in the east-west direction and 4.0 miles in the north-south direction.

The southern part of Clarkston Mountain consists of stratigraphic units that range in age from Cambrian to Silurian. The Nounan Formation of Cambrian age is the oldest. The St. Charles …

Horace W. Slocum Journals - Accession 23, Horace W. Slocum

Manuscript Collection

The Horace W. Slocum Journals include handwritten and typewritten accounts of Mr. Slocum’s journeys through South Carolina, North Carolina, Pennsylvania, Virginia, New York, Illinois, New Hampshire, and other states in search of rocks and minerals. Of special interest are photographs and maps of geological and mining sites in the typewritten, edited version of the journals. There is also a map index. The journals extend mainly from 1938 to 1956.

Petrology And Geochemistry Of The Killdeer Carbonates, John J. Delimata

Theses and Dissertations

The strata of the proposed Killdeer Formation (Stone, W. J., 1972) in the Killdeer Mountains of Dunn County, North Dakota is composed of a sequence of tuffaceous, calcareous, dolomitized and silicified flat lying sedimentary rocks of Tertiary age. It is the purpose of this report to describe and integrate the petrology and geochemistry of these sediments.

Fieldwork was conducted during the summer of 1972. Forty-three stratigraphic sections were measured and representative samples of each were collected for further analysis. Seven section were selected as representative of the area, and samples from these were studied in thin section with the petrographic …

Pleistocene Geology Of The Grand Forks-Bemidji Area, Northwestern Minnesota, Kenneth L. Harris

Theses and Dissertations

This is a report of a reconnaissance study of the Quaternary geology of an area in northwestern Minnesota. Surface geology was studied in an area extending from Grand Forks, North Dakota, in the northwest to Bemidji, Minnesota, in the southeast, an area of 10 723 square kilometres (4140 square miles). Near-surface stratigraphy was studied in the area of surface study and an adjacent area of equal size to the south.

Surface materials mapped range in age from Pleistocene to Holocene and include glacial, glaciofluvial, lacustrine, bog, eolian, and alluvial sediments.

Sixteen power-auger test holes, two measured sections along the Red …

Late Pleistocene And Holocene Geology Of The Moe Site, New Town, North Dakota, Richard W. Kornbrath

Theses and Dissertations

Eight stratigraphic units of Late Cenoioic age are present around the Moe Archeological Site near New Town, North Dakota. Unit Zero is a layer of glacial sediment consisting of grayish brown pebbly clay loam. Unit One consists of fluvial and beach sand and gravel. Unit Two consists of light yellowish brown, offshore lake silt that was deposited into a glacial lake in Late Wisconsinan time. Unit Three is a layer of glacial sediment consisting of grayish brown pebbly clay loam (Late Wisconsinan). Unit Four consists of fluvial sand and gravel (Late Wisconsinan}. Unit Five is a layer of slough sediment …

Glacial Stratigraphy Of Northeastern North Dakota, Howard Hobbs

Theses and Dissertations

Seven lithostratigraphic units (formations} composed dominantly of glacial sediment have been recognized in northeastern North Dakota. Three formations, the Falconer Formation (Harris and others, 1974}, the Dahlen, and Gardar Formations (Salomon, 1975). Have been previously recognized. Four formations, the Hansboro, Vang, Tiber and Cando Formations are newly recognized. Uncorrelated units of glacial sediment are described but not named. The formations are differentiated and correlated primarily by the proportion of crystalline (igneous and metamorphic rock fragments), carbonate, and shale grains in the coarse sand fraction (1 to 2 mm) of the glacial sediment. The proportion of shale grains was. Found to …
