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 …

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 …

Geology And Mineralization Of The Southeastern Part Of The Black Pine Mountains, Cassia County, Idaho, Don E. French

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The southeastern part of the Black Pine Mountains is located in the southeastern part of Cassia County, southern Idaho. The Utah-Idaho state line is three miles south of the studied area and the Cassia-Oneida county line bounds it on the east. The area is nearly square and encompasses about 30 square miles.

Devonian, Mississippian, Pennsylvanian, Permian, Tertiary and Quaternary sedimentary rocks are exposed within the area. Limestone, dolomitic limestime, quartzite, and bedded chert represent the Jefferson (?) Formation of Devonian age. It is 400 feet thick, however, the base is not exposed. The Milligen Formation is Early Mississippian in age …

Residual Nitrogen As It Affects Soil Fertility Under Irrigated Agriculture In A Tropical Wet-Dry Climate, Don Carlos Kidman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the Zapotitan Valley near San Andres, El Salvador, Central America, an experiment was conducted to determine the availability of residual soil N to corn grown during the rainy season. This was an extension of an experiment conducted during the preceding dry season. The variables of the dry season experiment were irrigation method, crop, and rate of fertilizer N application. Soil NO₃-N and NH₄-N were determined by soil sample analysis to a soil depth of 120 cm by 30 cm depth increments. The samples were taken at the end of the dry season experiment and again …

Mineralization In The Bear River Range, Utah-Idaho, John C. Chappelle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is t o describe the occurrences, interrelationships, and possible origin of the metallic mineral deposits of the Bear River Range. In this study, 21 mineral deposits containing minerals of lead, iron, copper, manganese, and zinc with quartz and carbonate gangue minerals, are described and classified as low temperature epigenetic hydrothermal deposits. The deposits predominantly occur in Cambrian limestone and dolomite formations located below formations with a high shale content. The deposition occurred as fracture filling and replacement along fractures associated with Teritary Basin and Range normal faults and joints which generally trend northerly in the …

Some Aspects Of Geochemistry Of The Water And Sediment Of Bear Lake, Idaho-Utah, Richard H. Fuller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Development by man through the last half century has caused a number of changes in Bear Lake. These changes include the diversion of Bear River water into Bear Lake, the pumping of lake water back into the river, and the building of breakwaters and other obstructions along the shore of Bear Lake.

The diversion of Bear River water into the lake has resulted in a yearly addition of an estimated 36,000 metric tons of calcium into the lake, which has caused the precipitation of an estimated minimum 90,000 metric tons of aragonite. The pumping of Bear Lake water back into …

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 …
