The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell
The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell
Bachelors Theses and Reports, 1928 - 1970
This thesis is essentially an abstract of the literature concerning occurrences in Montana of minerals with a non-metallic luster. The discussions give a general description of the occurrences of minerals as reported by the various references, but is not complete as less than 40 percent of the non-metallic minerals known to exist in Montana are discussed.
Microfauna Of The Colorado Shale In The Sunburst Dome Area, Montana, Merle W. Emmert
Microfauna Of The Colorado Shale In The Sunburst Dome Area, Montana, Merle W. Emmert
Bachelors Theses and Reports, 1928 - 1970
It has been hoped that a micropaleontological study of the shales of the Upper Cretaceous Colorado Group in northern Montana would reveal certain faunal zones which would serve as markers in an otherwise drab, undifferentiated, 1800 feet of grey, fissile shale. This paper presents the results of a study of the microfauna in certain samples from this shale in the Sunburst Dome area north of Shelby, Montana.
The Elkhorn Mine Of Jefferson County, Montana, David D. Walker
The Elkhorn Mine Of Jefferson County, Montana, David D. Walker
Bachelors Theses and Reports, 1928 - 1970
In 1901, after yielding metals valued in excess of five million dollars, it was considered worked out. Since that time the mine has passed through the hands of several owners, none of whom have failed to realize a profit from it. Although at no time since its zenith did it ever regain its once great production, it did provide a livelihood for those who worked it. Now with the American Smelting and Refining Company interested in it, perhaps it will once again become an important producer.
Sulphidizing Of Cerussite, Emil A. Kovacevich
Sulphidizing Of Cerussite, Emil A. Kovacevich
Bachelors Theses and Reports, 1928 - 1970
The oxide minerals, such as cerussite, are not as amenable to flotation as the sulphide minerals. Sulphidization is the usual means used today to increase the recovery of an oxide flotation; however, sulphidization under the most advantageous conditions does not yield very satisfactory recoveries.
Faunal Studies Of The Lower Jefferson Limestones, James L. Eymann
Faunal Studies Of The Lower Jefferson Limestones, James L. Eymann
Bachelors Theses and Reports, 1928 - 1970
The exact geologic age of the Jefferson limestone in Montana has not been definitely determined, other than it is probably of upper, but possibly in part of middle Devonian age. Although not of immediate or apparent economic importance, the determination of the exact age of the Jefferson limestone may be of much value in connection with the discoveries of large quantities of oil in Devonian strata in the northern Great Plains and, in particular, with the extensive deep drilling in northeastern Montana which is anticipated during the summer of 1951.
A Mineralogical Investigation Of Some Montana Hydrobiotites, John W. Baker
A Mineralogical Investigation Of Some Montana Hydrobiotites, John W. Baker
Bachelors Theses and Reports, 1928 - 1970
Vermiculite is one of the most recent important nonmetallic minerals to be exploited for use in the industrial world. For this reason, the fund of knowledge relating to this mineral is rather limited. This paper represents the results of laboratory studies that were undertaken to contribute data to this fund of knowledge.
Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer
Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer
Bachelors Theses and Reports, 1928 - 1970
Thermal analysis is a relatively new method of determining the general composition of certain mineral substances. As is demonstrated by much of the literature previously written, clays and carbonates are especially adaptable to this method. The full importance of the method is not as yet realized, but it is rapidly approaching that point.
Chemical Analysis Of Igneous Rocks And Variation Diagrams Of Petrographic Provinces Of Montana, Frederick M. Hilpert
Chemical Analysis Of Igneous Rocks And Variation Diagrams Of Petrographic Provinces Of Montana, Frederick M. Hilpert
Bachelors Theses and Reports, 1928 - 1970
A total of 179 chemical analyses of igneous rocks are available for the state of Montana, but these analyses do not cover the entire state in a satisfactory manner. There has been an emphasis on the central part of the state, and an almost complete lack of interest in the southern portion of Montana.

In the following sections of this report, I will discuss as fully as possible both the theoretical and practical aspects of the roasting, leaching, and electrowinning steps, as well as the economic considerations of the process. The results of my laboratory work will, of course, be integrated to the process.
The Gallium-Indium Constitutional Diagram, Richard E. Gaffney
The Gallium-Indium Constitutional Diagram, Richard E. Gaffney
Bachelors Theses and Reports, 1928 - 1970
Because of the discrepancy as to whether there is solid solubility in the gallium-indium system, and the fact that no alloys with less than 1% indium were ever investigated; the possibility of solid solubility in either or both ends of the diagram was not overlooked. According to Hume-Rothery, two alloys with the same relative positions on the Periodic Chart should have about the same alloying habits.
Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.
Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.
Bachelors Theses and Reports, 1928 - 1970
Amalgam Metallurgy, a relatively new expression in the technology of metal extraction, was first chosen to describe certain new processes developed at the Duisburg Copper Works in Germany. The idea of using mercury, a costly and poisonous metal, as an intermediate in heavy chemical industry and in polarography are of recent origin; with the exception of a series of patents of little significance and occasional comments in the literature, the work is hardly known.

Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.
Bachelors Theses and Reports, 1928 - 1970
Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to corrosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world.
Resistance Of Solid Inconel To Attack By Liquid Indium, David C. Hendra
Resistance Of Solid Inconel To Attack By Liquid Indium, David C. Hendra
Bachelors Theses and Reports, 1928 - 1970
The role of liquid metals in industry is rapidly becoming of increasing importance. The physical and chemical tendencies of metals in the liquid condition must be ascertained before a metal in this form can be put to practical usage. In very many stages of mineral processing and recovery, in molten-metal baths for temperature control on heat treating, and in several industries where heat transfer is an important aspect, metals may be at one time or another in a liquid condition.
Mineralogy Of The Silver King Mine Of Park City, Utah, Pierce D. Parker
Mineralogy Of The Silver King Mine Of Park City, Utah, Pierce D. Parker
Bachelors Theses and Reports, 1928 - 1970
Except for the early work of Boutwell and Irving, little has been published on the geology of the Park City mining district. For this reason and because of the availability of a selected suite of ores from the Silver King mine of this area, this writer chose the mineralogy of the Silver King mine as a senior thesis for the department of Geology of the Montana School of Mines.
A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce
A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce
Bachelors Theses and Reports, 1928 - 1970
Any investigation of the many gold silver producing districts of Montana will necessarily include the name Zosell. The Zosell Mining District, often referred to as the Emery District, was never a major producer in the state; however, its location, history, type of deposit, and character of ore, has drawn the interest of many prominent investigators of the mineral industry.
Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta
Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta
Bachelors Theses and Reports, 1928 - 1970
The exact upper boundary of the Devonian of Montana has long been a controversy, as is true of the Devonian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.

Geology Of A Postulated Volcanic Vent Northeast Of Whitehall, Montana, C. H. Hewitt, H. D. Olson
Bachelors Theses and Reports, 1928 - 1970
The possibility of defining the roots of one of the volcanic sources of the Upper Cretaceous Livingston formation led to the detailed mapping upon an enlarged aerial photograph of a complexly intruded, folded, and faulted area about 10 miles northeast of Whitehall, Montana.
A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll
A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll
Bachelors Theses and Reports, 1928 - 1970
The oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation.
