The Renova "Syenite" Porphyry Madison County, Montana, James H. Clement May 1950

The Renova "Syenite" Porphyry Madison County, Montana, James H. Clement

Bachelors Theses and Reports, 1928 - 1970

Unique feldspar porphyries, syenitic in appearance, and granitic in composition, form an unusually thick sill intrud­ing pre-Cambrian Belt graywacke about eight miles south of Whitehall in southwestern Montana. Commercial deposits of gold and silver ores occur nearby, and may possibly be genet­ically related to the porphyry, although direct association is not evident. The geologic age is believed to be late Cretaceous or early Tertiary, and the sill may be related to the Tobacco Root batholith.


A Study Of Some Pre-Cambrian Schists From Yankee Jim Canyon, Park County, Montana, Charles K. Presley May 1950

A Study Of Some Pre-Cambrian Schists From Yankee Jim Canyon, Park County, Montana, Charles K. Presley

Bachelors Theses and Reports, 1928 - 1970

One of the most highly deformed metamorphic rock series in Montana is exposed fifteen miles north of Yellowstone Park, Wyoming in the great gorge known as Yankee Jim Canyon, which was formed by Yellowstone River at that point. These metamorphics are Pre-Cambrian in age, and are almost certainly sedimentary in origin, although the involved and intricate folding which they have undergone has long since obliterated any superficial traces of that origin.


The Lilly Mine Of Powell County, Montana, Wilbur Aikin May 1950

The Lilly Mine Of Powell County, Montana, Wilbur Aikin

Bachelors Theses and Reports, 1928 - 1970

For many years the Elliston District, of Powell County has been a minor producer of gold, lead, zinc, and silver. Although never among the largest producing districts of the state, it has with the exception of the war years supplied a notable tonnage of ore to the neighboring mills ever since the first placer and lode claims were located there during the late eighteen hundreds.


Geology Of Smoke Hollow Area 8 Miles Southeast Of Deerlodge, Powell County, Montana, Floyd C. Bossard May 1950

Geology Of Smoke Hollow Area 8 Miles Southeast Of Deerlodge, Powell County, Montana, Floyd C. Bossard

Bachelors Theses and Reports, 1928 - 1970

This investigation was undertaken primarily as a problem in geologic mapping. The stratigraphy was studied as to the character, age, and sequence of the geologic formations that are exposed. The conclusions were based principally on the field relationships and lithology because no fossils were found.


Structure Of Southwestern Montana, Donald W. Levandowski May 1950

Structure Of Southwestern Montana, Donald W. Levandowski

Bachelors Theses and Reports, 1928 - 1970

Intrusions of granitic rocks on a large scale are commonly found in the central part of folded mountain systems. Igneous rocks, intrusive and extrusive, are widespread in the mountains of southwestern Montana. An examination of the structural pattern of this area indicates that the fold trends form a radial pattern. How and why this pattern formed and its relation to the igneous activity in the area have not yet been discussed in the literature.


Basic Sills In Cottonwoood Creek Canyon, Jefferson County, Montana, Dale F. Kittel May 1950

Basic Sills In Cottonwoood Creek Canyon, Jefferson County, Montana, Dale F. Kittel

Bachelors Theses and Reports, 1928 - 1970

A stratigraphic section of about 2600 feet of upper Beltian to lower Devonian formations exposed in Cottonwood Creek Canyon 11 miles east of Whitehall, Montana, contains about 20 igneous sills. These sills are from 5 to 20 feet thick, and grade from granogabbro to quartz basalt, except for one sill which is 165 feet thick, and is composed of granogabbro and red syenite. The whole sedimentary series is isoclinally folded, and the sills follow the bedding planes closely with localized crosscutting through the beds.


Was Assimilation Important In The Formation Of The Boulder Batholith?, Richard Marvin May 1950

Was Assimilation Important In The Formation Of The Boulder Batholith?, Richard Marvin

Bachelors Theses and Reports, 1928 - 1970

Examination of a rock suite from the northern end of the Boulder batholith reveals that four of the eight criteria for assimilation as given by Grout are present. Thus, in the opinion of the writer, there is evidence and trends to signify assimilation, but no indication of the importance that it played in the formation of the Boulder batholith.


The Bighorn Mountains, The Little Rocky Mountains And The Bowdoin Dome Uplifts, E. J. O'Connell May 1950

The Bighorn Mountains, The Little Rocky Mountains And The Bowdoin Dome Uplifts, E. J. O'Connell

Bachelors Theses and Reports, 1928 - 1970

The purpose of this paper is to secure an actual figure describing the amount of uplift in the Bighorn Mountains, the Little Rocky Mountains and the Bowdoin Dome. To the writer’s knowledge, the amount of uplift in the areas mentioned has not been determined before. Such a figure could be useful in structural studies of Montana and Wyoming, because the amount of uplift is a fair measure of the intensity of orogenic forces; also, the amount of uplift is a prerequisite to the determination of the amount of erosion.


Consumptive Use Of Water Studies In The Ashley And Ferron Creek Areas Of Utah, Elden E. Fisher May 1950

Consumptive Use Of Water Studies In The Ashley And Ferron Creek Areas Of Utah, Elden E. Fisher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The inadequacy of water and power supplies in Utah for agriculture, for industry, for domestic and community consumption has retarded the State's economic growth. Shortages of water and hydroelectric power are the principle impediments to the full realization of other potentials of Utah, that is, the full use of its arable lands, the wide and diversified use of its industrial raw materials, and the unrestricted development of its communities. The problem of securing additional sources of water and power has resolved itself into one of major concern. The objective of this study was to determine unit values of consumptive use …


Drainage By Pumping In The Lewiston Area, Utah, Paul J. Pehrson May 1950

Drainage By Pumping In The Lewiston Area, Utah, Paul J. Pehrson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In irrigated areas it often becomes necessary to provide means by which the excess water may be removed. After a period of time if these drainage provisions are not made, it may become necessary, because of the saline soils or water logged condition that may develop, to abandon the land for agricultural purposes.

The increases of irrigation on the higher lands in Utah has resulted in an increased need for drainage on much of the lower land in the valleys. This increased need for drainage has long been recognized and in 1947 it influenced the Utah Agricultural Experiment Station, in …


An Investigation Into The Precipitation Of Copper From Mine Water By Cupric Copper Reduction, And The Subsequent Precipitation Of Copper As Cuprous Chloride, Jack T. Gentry Apr 1950

An Investigation Into The Precipitation Of Copper From Mine Water By Cupric Copper Reduction, And The Subsequent Precipitation Of Copper As Cuprous Chloride, Jack T. Gentry

Bachelors Theses and Reports, 1928 - 1970

The objective of this thesis is to determine the possibility of applying a different method to the re­covery of the copper dissolved in the Butte mine waters, and thereby precipitate a purer cement copper with greater efficiency and less iron consumption.
