Czarina Mine, Butte, Montana, Prodyot K. Das Jun 1950

Czarina Mine, Butte, Montana, Prodyot K. Das

Bachelors Theses and Reports, 1928 - 1970

The Czarina mine operated for a short time during the last Great War, lies in the southwestern corner of the Butte mining district of Montana. This area was worked during the extensive silver mining in Butte during the 1890's, and was prospected from time to time in later years. The orebody of the mine consists of fissure fillings of manganese mineral oxidized to a certain depth, in a fracture zone of the Boulder Batholith.

Mineralization Of The Bonanza Mine, H. M. Callaway Jun 1950

Mineralization Of The Bonanza Mine, H. M. Callaway

Bachelors Theses and Reports, 1928 - 1970

The Bonanza mine of the Emery mining district in Powell County is on the largest veins in the area, and is developed to a depth of 680 feet by an incline shaft following the dip of the structure. Sulfide ores carrying gold and silver values are mined throughout the area which is easily accessible by road from Deerlodge, Montana, ten miles west of the district.


Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick Jun 1950

Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick

Bachelors Theses and Reports, 1928 - 1970

This paper, a study of the fauna of the Pilgrim formation at South Boulder Creek in southwestern Montana, represents a laboratory study of the fossil specimens collected by Dr. Alvin Hanson during the summer of 1949. The scope of investigation includes identification and classification of the faunas, their stratigraphic relationship and zonal subdivisions.


Foraminifera From The Colorado Shale Near Sunburst, Montana, Frank R. Reynolds Jun 1950

Foraminifera From The Colorado Shale Near Sunburst, Montana, Frank R. Reynolds

Bachelors Theses and Reports, 1928 - 1970

One of the many secrets which planet Earth has jealously kept from its inhabitants is the microscopic fossil form known as the foraminifer. It hides in common shale, awaiting the patient and painstaking searcher. In furthering the study of the foraminifera of the Colorado group of for­mations in Northern Montana, the United States Geological Survey has collected several suites of shale samples from the Sunburst Dome, five to ten miles south of the Canadian border and twenty-five miles north of the city of Shelby, Montana.


Fauna And Stratigraphy Of The Meagher Formation At Three Localities In Southwestern Montana, William J. Van Matre Jun 1950

Fauna And Stratigraphy Of The Meagher Formation At Three Localities In Southwestern Montana, William J. Van Matre

Bachelors Theses and Reports, 1928 - 1970

In the past 75 years, the scenic area about the head­waters of the great Missouri River has attracted the atten­tion of many leading stratigraphers and paleontologists; for in this area bountiful outcrops of Paleozoic fossil horizons are available for study and correlation.


Mottling In The Meagher Limestone, Ronald J. White Jun 1950

Mottling In The Meagher Limestone, Ronald J. White

Bachelors Theses and Reports, 1928 - 1970

The middle Cambrian Meagher limestone of southwest Montana is characterized by mottled members that are finely crystalline in the tan part and microcrystalline in the dark matrix. As seen in the literature, similar mottled limestones are thought to be an arrest­ed stage in the dolomitization, or alteration of limestones.


Foraminifera Of The Colorado Shale At Fort Benton, Montana, Robert E. Willson Jun 1950

Foraminifera Of The Colorado Shale At Fort Benton, Montana, Robert E. Willson

Bachelors Theses and Reports, 1928 - 1970

Shale is known to be a source-bed for oil, and the Colorado shale which is over 2000 feet thick in places may well be the source for the oil which is now accumulated in the included or closely associated sandstones. A thorough study of the fossil content may not only be helpful in correlation of Cretaceous sediments, but it likewise may be the starting point for studies -which could eventually lead to the discovery of unknown mineral deposits.


A Study Of The Divide-Dewey Contact Of The Boulder Batholith, Francis M. Young Jun 1950

A Study Of The Divide-Dewey Contact Of The Boulder Batholith, Francis M. Young

Bachelors Theses and Reports, 1928 - 1970

The batholith is dated as Paleocene or early Eocene. The rocks of the batholith in this area are classified as ranging from quartz-granodiorite to granodiorite. Variation in mineral content causes a chance in color tone from light to dark gray. swarms of inclusions occur in the igneous rock near the contact.


A Mineral Dressing Study Of The Benefication Of Philipsburg Manganese Carbonate Ore, Frank M. Antonioli May 1950

A Mineral Dressing Study Of The Benefication Of Philipsburg Manganese Carbonate Ore, Frank M. Antonioli

Bachelors Theses and Reports, 1928 - 1970

The beneficiation of rhodochrosite ore to the extent that it is suitable for nodulizing and subsequent use in the steel industry is intriguing. Such ores from certain mines is relatively easy to beneficiate, but the rhodo-chrosite ore from several deposits of the Philipsburg district has never been successfully up-graded by any of the several known beneficiating methods.


Physiographic Surfaces And Weathering Near Butte, Gordon B. Brox May 1950

Physiographic Surfaces And Weathering Near Butte, Gordon B. Brox

Bachelors Theses and Reports, 1928 - 1970

Three cycles of erosion have modified the Boulder batholith. The earliest cycle produced a peneplaination that has been largely obliterated by a partially completed intermediate cycle, and the recent cycle now in progress.


An Investigation Of The Gallium-Indium Binary System, Allen D. Kennedy May 1950

An Investigation Of The Gallium-Indium Binary System, Allen D. Kennedy

Bachelors Theses and Reports, 1928 - 1970

Twenty-four alloys, at 5 weight per cent or smaller intervals, were investigated by the thermal method. Very low temperatures had to be attained, because most of the alloy melts supercooled remarkably. Analysis showed only a liquidus and solidus line, and the solidus temperature was the same for each alloy.


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.


A Preliminary Study Of The Benefication Of Montana Corundum, John L. Brown May 1950

A Preliminary Study Of The Benefication Of Montana Corundum, John L. Brown

Bachelors Theses and Reports, 1928 - 1970

The objective of this thesis was to affect an effic­ient and economical recovery of corundum. The corundum oc­curs as a crude ore admixed with quartz and other diluents. Yet, this material is a potential Montana resource of a val­uable non-metallic mineral. In view of the strategic import­ance and the relatively small production of this mineral in the United States, it seems advisable at this time in world affairs to investigate every possible source of this mineral.


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.


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.


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.


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.
