Importance Of Unconformities To Oil Occurrence In Montana, Robert E. Evenson

Bachelors Theses and Reports, 1928 - 1970

Although the majority of geologic structures in Montana have been tested in the search for petroleum, only a few have been found to contain commercial quantities of either oil or gas, and with each successive dry hole, producers are becoming more and more wary of investing capital in new wells located on structural features alone. It is apparent that if new oil and gas fields are to be found in Montana, exploration must be done on the basis of some­thing other than structure, or combined with structure.

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

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_.

A Study Of The Effect Of The Maximum Melt Temperatures Upon The Degree Of Supercooling Of Gallium, Wilfred E. Nagel

Bachelors Theses and Reports, 1928 - 1970

If, in a system at a giv­en temperature, there should occur a decrease in free energy and this decrease does not take place, then the resulting condition of the system is termed supercooling. A common example of the phenomenon is found in the liquid-to-solid transition of many substances, when the temperature of the liquid may be lowered below its freezing point without solidification. Similar phenomenon occurs in the gas-to- liquid, gas-to-solid, and polymorphic transformations.

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

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.

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.

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 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.

The Isothermal Transformation Curve For S.A.E. 6150, Charles Arentzen

Bachelors Theses and Reports, 1928 - 1970

More than 3000 years ago, men began quenching and tem­pering tools to improve their physical properties. The an­cient people found that iron was easier to shape and form in a heated condition. Charcoal was used as the fuel, and when the shaping process was completed, the smiths cooled the piece in the most obvious way, quenching in water. Quite un­intentionally, these people stumbled on the process for im­proving the properties of iron, and the art of blacksmithing began.

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

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 Alloys Of Gallium And Indium, C. J. Adams

Bachelors Theses and Reports, 1928 - 1970

Thermal analysis VIPS used to construct cooling and heating curves from which the phase diagram was determined. The data for the entire set of cooling curves were obtained by the use of mercury thermo­meters.

Hot-Dip Aluminizing Of Low-Carbon Steels, Claude R. Barnes Jr.

Bachelors Theses and Reports, 1928 - 1970

In a relatively short period of sixty-five years, aluminum has grown to the rank of fifth in total weight of met­als produced in the world. Throughout its short life, aluminum has been found to have excellent corrosion-resistant properties; yet only in recent years has aluminum been under consideration as a corrosion-resistant coating for iron and steel.

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.
