The Dry Lake Section Of The Brazer Foundation, James S. Yolton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Dry Lake section of the Brazer formation, totalling 3100 feet in thickness, is an excellent exposure containing an abundance of fossils many of which are well preserved. The fauna indicates that the formation is to be correlated with the Upper Iowan and Chester series of the type Mississippian system in the Mississippi Valley section. Substantial fossil evidence indicates the following correlation for the Brazer formation members. The C unit represents the western equivalent of the Middle Meramec group, i.e., the Salem and St. Louis limestones. The D member is decidedly Ste. Genevieve in general faunal aspects but, because of …

Spectrographic Analysis Of Montana Limestones, Clifford A. Barkell

Bachelors Theses and Reports, 1928 - 1970

Spectrographic analysis of limestones as a possible method of correlation of geologic formations is an altogether new line of investigation. As far as known the only previous work consists of a few analyses made by Fred Lines in his bachelor thesis work at Montana School of mines in the spring of 1942.

Concentration By Flotation Of A Complex Galena - Sphalerite - Chalcopyrite Ore From The Nine Mile District Near Missoula, Montana, Truxton J. Fisher, John L. Tokich

Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis

Bachelors Theses and Reports, 1928 - 1970

In studying the Cut Bank field and its numerous wells, it is found that dry holes are surrounded by producing wells, and also that the field as a whole is very irregular; water, oil, and gas zones in many cases following no definite pattern. In some instances, this phenomenon may be due to the lensing and thinning of the producing sands, but it is evident that this is not the only factor. There­fore, the controlling factors must be porosity and permeability.

Zinc Plating Magnesium, Howard Wilbur Adam

Bachelors Theses and Reports, 1928 - 1970

Magnesium and magnesium alloys are becoming more and more important in modern industry. Their use in the aviation industry has been greatly curtailed because of their comparatively poor resistance to corrosion especially in moist atmospheres. Many methods have been adopted to improve their resistance to corrosion.

The Electrodeposition Of Iron-Manganese Alloys, Earl C. Roberts

Bachelors Theses and Reports, 1928 - 1970

Various electrolytes were experimented with in an attempt to deposit an iron-manganese alloy. An Alloy was obtained from a solution containing ferrous ammonium sulfate, manganous sulfate, and ammonium sulfate. Further experimentation was done in an effort to determine the optimum conditions of deposition and the highest manganese alloy which could be produced.

Coal In Montana, Clifford A. Barkell

Bachelors Theses and Reports, 1928 - 1970

Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 4₁000,000.00 annually.

The author has made a study of an assemblage of fossils from the Blacktail Range near Dillon Montana with the purpose in view of attempting a correlation of that group with the fauna of the Big Snowy Group. Fossils have also been obtained from a limestone formation in northwestern Montana and from four different areas in the Amsden formation in central and western Mont­ana.

The Velocity Of Falling Particles In A Liquid Medium, Elliott Coldwater

Bachelors Theses and Reports, 1928 - 1970

The investigation was prompted by the fact that there seemed to be some discrepancy between the results published by Richards,and the empirical figures used in classification and in gravity concentration. Further, the work of Richards was restricted to quartz and galena whereas this study also includes pyrite and calcite.

Age Hardening Of Copper-Aluminum Alloy Castings, Frank Randall

Helena And Ennis Talc Deposits, Howard N. Anderson

Bachelors Theses and Reports, 1928 - 1970

The purpose of this report is to collect geologic data concerning two Montana talc occurrences at Helena and Ennis and to offer some explanation as to their origin. The two deposits cited are in somewhat similar lithologic settings and both possess the same mineralogical and structural features. Because of this similarity only the Helena deposit is covered in detail.

Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines

Bachelors Theses and Reports, 1928 - 1970

The correlation of non-fossiliferous drill samples is one of the difficult problems that is en­countered in sub-surface stratigraphy. In order to truly correlate a formation, it must have some dis tinctive features and have an areal persistence of these features. These requirements are probably met best by limestone.

Bachelors Theses and Reports, 1928 - 1970

Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much re­search has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.

Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson

Bachelors Theses and Reports, 1928 - 1970

With the increasing importance of manganese in the metallurgical fields of today and tomorrow, ex­tensive work along the lines of its successful ex­ploitation has been accomplished by many investiga­tors. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.
