Geology And Geological Structure Of The Alberta And Saskatchewan Plains, William E. Topley
Geology And Geological Structure Of The Alberta And Saskatchewan Plains, William E. Topley
Bachelors Theses and Reports, 1928 - 1970
Alberta, responsible for ninety per cent of Canada's output, had, by 1947 entered into her fifth year of production decline. Only ten per cent of Canada's oil requirements were secured from home fields. Ninety per cent had to be imported, mainly from the United States. How long could imports be maintained on present levels? During the year, the United States had started rationing; in one sector of its domain. Would this become general? If so, what was the answer for Canada?
The Fort Union Formation Of Montana And Adjacent Areas, Charles Christman
The Fort Union Formation Of Montana And Adjacent Areas, Charles Christman
Bachelors Theses and Reports, 1928 - 1970
The Fort Union formation is one of the most important and best known geologic formations of the northern Great Plains, and is found lying almost horizontal at the surface over large areas in this region.

Manganese Oxide Deposits Near Butte And Development Since 1942, Emmett M. Gilmore
Bachelors Theses and Reports, 1928 - 1970
The manganese minerals occur in the peripheral zone of the Butte district with quartz in veins, which at depth contain galena and sphalerite closely associated with silver-bearing minerals. The manganese oxides are all oxidation products formed by weathering of primary rhodochrosite or rhodonite.
Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe
Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe
Bachelors Theses and Reports, 1928 - 1970
Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company accounted for 90 percent of the total shipments of manganese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.
Sandstones Of The Lance And Fort Union Formations, Alan G. Conner
Sandstones Of The Lance And Fort Union Formations, Alan G. Conner
Bachelors Theses and Reports, 1928 - 1970
The Fort Union and Lance formations are widespread terrestrial sediments exposed in Montana, North Dakota, South Dakota, Wyoming, and Canada. Their stratigraphic position, especially that of the Lance, has long been in doubt, and has provoked much controversy among geologists.
The Geology And Mineral Deposits Of British Columbia, John A. Downing
The Geology And Mineral Deposits Of British Columbia, John A. Downing
Bachelors Theses and Reports, 1928 - 1970
The province of British Columbia, with an area of 359,279 square miles, includes a large part of the Canadian Cordillera that is the western mountains of Canada. It is the leading province of Canada in the production of lead, zinc, and silver, and third among the provinces in the output of gold, copper, and coal.
Roasting And Leaching Of Montana Chromite, Jerry D. Murphy
Roasting And Leaching Of Montana Chromite, Jerry D. Murphy
Bachelors Theses and Reports, 1928 - 1970
The United States, although the leading consumer of chromite, depends almost entirely on imports for its supply. Domestic production of chromite is limited, because high-grade imported ore is plentiful and inexpensive in normal times. There are several large deposits of chromite in the United States, representing millions of tons of low grade ore. These deposits form a strategic reserve that must be used in time of national emergency.
A Mineral Dressing Study Of The U.S. Grant Ore, John Emmett Murphy
A Mineral Dressing Study Of The U.S. Grant Ore, John Emmett Murphy
Bachelors Theses and Reports, 1928 - 1970
This investigation concerns the development of a satisfactory method or extracting or concentrating gold and silver from the ores of the U. S. Grant Mine. The choice between applying an extractive process and one by which the valuable mineral constituents are concentrated depends on more than one factor.
Sulfatizing Roasting Of A Copper Sulfide Ore, Walter D. Finnegan
Sulfatizing Roasting Of A Copper Sulfide Ore, Walter D. Finnegan
Bachelors Theses and Reports, 1928 - 1970
At present copper sulfide ores are recovered by pyrometallurgical processes. While the recovery of copper from sulfide ores by hydrometallurgical means has long been considered attractive, the impurities, low recovery and mechanical difficulties have kept this process from becoming commercial.
Geology And Ore Deposits Of The Salt Chuck-Rush And Brown Mine Area Prince Of Wales Island, Alaska, Judson H. Whitman
Geology And Ore Deposits Of The Salt Chuck-Rush And Brown Mine Area Prince Of Wales Island, Alaska, Judson H. Whitman
Bachelors Theses and Reports, 1928 - 1970
The Salt Chuck, Rush and Brown, and adjacent mines and claims form an area of approximately 15 square miles near the head of Kasaan Bay about 10 miles northwest of the village of Kasaan on Prince of Wales Island in southeastern Alaska. It is an area of moderate relief in which the hills rise from the water’s edge to heights of some 500 feet. Most of the area is covered with dense vegetation and muskeg.
A Discussion Of The Geology And An Isopach Map Of The Pennsylvanian System In Wyoming And Adjacent Areas, B. R. Alto
A Discussion Of The Geology And An Isopach Map Of The Pennsylvanian System In Wyoming And Adjacent Areas, B. R. Alto
Bachelors Theses and Reports, 1928 - 1970
Pennsylvanian strata in Wyoming and adjacent areas have been the subject of much work and discussion. Most of the work has been due to the economic importance of the system as an oil producer in this region. Oil production from strata of Pennsylvanian age is rather recent history; and therefore, much of the available information is localized and incomplete.
Flotation Concentration Of A Montana Lead-Zinc-Silver-Ore, Grover W. Gregson
Flotation Concentration Of A Montana Lead-Zinc-Silver-Ore, Grover W. Gregson
Bachelors Theses and Reports, 1928 - 1970
The Mike Horse mine, in the Huddelston mining district, is fifty-two miles northwest of Helena, Montana. The mine was discovered in 1898 by Joseph Heitmiller. There was only minor production from the date of discovery until 1915; the main drawback being lack of good road.

The Physiographic History Of Western Montana And Northwestern Idaho, John R. Kavanagh
Bachelors Theses and Reports, 1928 - 1970
Millions of years of physiographic changes have conditioned us to the fact that our present drainage is a temporary feature. Rivers once flowing opposite to their present direction is not an unusual condition for physiographers to suggest.
An Isopach Map And A Discussion Of The Permian In Wyoming And Adjacent Areas, Willard Leskela
An Isopach Map And A Discussion Of The Permian In Wyoming And Adjacent Areas, Willard Leskela
Bachelors Theses and Reports, 1928 - 1970
The accelerated post-war demand for petroleum products with resultant high prices and dwindling reserves has spurred producers to an extensive search for new fields and for additional production in known fields. Exploration and discovery is dependent on the collection and correlation of vast amounts of data both in the field and that found in literature.
Karst Kamp Asbestos Deposits Gallatin County, Montana, Thomas L. Wilson
Karst Kamp Asbestos Deposits Gallatin County, Montana, Thomas L. Wilson
Bachelors Theses and Reports, 1928 - 1970
Karst Kamp, a southwestern Montana recreation resort, is 32 road miles south of Bozeman on the east bank of the Gallatin River in a narrow V-shaped valley flanked on the west by the rugged Madison mountain range and on the east by the equally rough Gallatin range. The asbestos deposit itself lies approximately one-half mile northwest of the ranch on a heavily timbered "Alpine-like" slope nearly 1200 feet above the floor of the valley.
Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott
Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott
Bachelors Theses and Reports, 1928 - 1970
In 1915 the United States Geological Survey published a folio by Calkins and Emmons on the geology of the Philipsburg Quadrangle, which adjoins the area now under study to the west. Geology of this portion of Montana had not been mapped previously; consequently the purpose of this thesis is to make a geological reconnaissance of the stratigraphy and structure of the area.
A Study Of The Action Of Various Energizers In The Carburization Of Steel, William N. Warren
A Study Of The Action Of Various Energizers In The Carburization Of Steel, William N. Warren
Bachelors Theses and Reports, 1928 - 1970
The object of casehardening is to produce articles of steel having a tough or ductile interior and a hard surface. Quenching produces a surface somewhat harder than the interior, but in order to obtain a high surface hardness, the percentage of alloying elements in the steel must be raised to such an extent that the core or central portion becomes hard and brittle also.
A Study Of The Diffusion Of Electroplated Coatings In The Solid State., Michael R. Writt
A Study Of The Diffusion Of Electroplated Coatings In The Solid State., Michael R. Writt
Bachelors Theses and Reports, 1928 - 1970
The term diffusion means an equalization or homogenization of diverse materials. Specifically applied to metals, diffusion is the interchange of atoms. It is, in effect, an invasion of one crystal lattice by the atoms of one or more other crystal lattices. Therefore, the study of diffusion must involve the geometry and physics of crystal lattices as well as their energies.
Leaching Of Low Grade Rhodochrosite, E. D. King
Leaching Of Low Grade Rhodochrosite, E. D. King
Bachelors Theses and Reports, 1928 - 1970
Although there are many uses for manganese today, none of them approaches its importance as a deoxidizing agent in the manufacture of steels. Without manganese the steelmaking industry would be very seriously handicapped. The metallurgy of manganese has been developed around the high-grade ores, and unfortunately, our reserves of high-grade ores are very limited.
Geology Of Montana, Stanley G. Olson
Geology Of Montana, Stanley G. Olson
Bachelors Theses and Reports, 1928 - 1970
A vast amount of information has been published by many workers on particular features of the geology of the state of Montana, as well as on local geology of many smaller divisions. However, a satisfactory summary of the geology in general, which would include all phases of geology as they apply to the greater area of the entire state, has not been published.
An Investigation Of Age-Hardening In A Commercial Copper-Beryllium Alloy, Terry Horne
An Investigation Of Age-Hardening In A Commercial Copper-Beryllium Alloy, Terry Horne
Bachelors Theses and Reports, 1928 - 1970
This investigation is concerned with the age-hardening process as exemplified by the aging of a commercial Cu-Be alloy and, in particular, with this process as determined by X-ray methods. The amount of information available on age-hardening of commercial alloys is scanty and what information there is, is inaccurate.
Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr
Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr
Bachelors Theses and Reports, 1928 - 1970
The possible benefits of oxygen enriched atmosphere roasting have been known to metallurgists for many years, but only since the development of equipment and processes to produce cheap oxygen in very large amounts has much serious consideration been given this matter.
A Study Of The Physical Properties Of Low Tin Solders, Cornelius P. Dwyer
A Study Of The Physical Properties Of Low Tin Solders, Cornelius P. Dwyer
Bachelors Theses and Reports, 1928 - 1970
In 1947, out of the 100,000 long tons of tin consumed in the United States, 25,000 tons went into solder. Tin plate took 39,000 tons while babbit, bronze and collapsible tubes accounted for approximately 17,000 tons. Solder ranked second to tin plate and required more than the next three major uses combined.
The Effect Of Manganese And Magnesium On The Hardening Of Copper-Aluminum Alloys, Robert M. Hansen
The Effect Of Manganese And Magnesium On The Hardening Of Copper-Aluminum Alloys, Robert M. Hansen
Bachelors Theses and Reports, 1928 - 1970
During recent years, duralumin and all aluminum alloys have been made the object of much discussion regarding their hardening mechanism. The commercial success of nearly all of the alloys of aluminum and magnesium is dependent on their ability to age or precipitation harden.
The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
Bachelors Theses and Reports, 1928 - 1970
Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the attention that it merits.
An Investigation Of The Anodic Oxidation Of Aluminum In A Sulfuric Acid Electrolyte, William D. Michaely
An Investigation Of The Anodic Oxidation Of Aluminum In A Sulfuric Acid Electrolyte, William D. Michaely
Bachelors Theses and Reports, 1928 - 1970
When aluminum is allowed to stand in air or is heated in air, a thin oxide film is produced on the metal. If aluminum is made the anode in a suitable electrolyte and a current applied, a coating is obtained which is similar to that produced in air, but may be effected much quicker. This film is thicker, harder, more resistant to corrosion and abrasion, and more adhesive than the natural oxide. The film is porous and makes an excellent adsorptive for dyes and pigments.
Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell
Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell
Bachelors Theses and Reports, 1928 - 1970
The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.
