Comparative Studies Of Oklahoma And Missouri Granites With Special Attention To The Heavy Minerals Of The Oklahoma Granites, Russell B. Maurer

Bachelors Theses and Reports, 1928 - 1970

When examined petrographically the granites of Oklahoma show a marked similarity to the granites of South­eastern Missouri. The same heavy accessory mineral suites are present in the granites of both regions and include: fluorite, zircon, apatite, titanite and epidote. This similarity was further shown by the actual correlation of the heavy mineral suites by types, these types being, based on the heavy mineral distributions of the Missouri Granites.

Benefication Of An Oxidized Lead Ore From The Franklin Mine Lewis And Clark County, Jack D. Mclenegan

Bachelors Theses and Reports, 1928 - 1970

This thesis is concerned with the beneficiation of an oxidized lead ore. Emphasis was placed upon concentration by flotation rather than by gravity methods, although some investigation was made with the Wilfley shaking table. The concentration of lead minerals received most consideration in the problem, but wherever possible attempts were made to increase the silver and gold concentration along with the lead.

An Isopach Map And Discussion Of Triassic Strata In Southern Montana And Wyoming, Robert G. Thompson

Bachelors Theses and Reports, 1928 - 1970

Oil and gas have been found in the Triassic strata of Wyoming. Although the Triassic has not as yet proven to be a large producing horizon it is very probable that ad­ditional oil will be found in Triassic strata in the future, and it is one of the goals at which oil well drillers aim their tools.

Foraminifera From The Colorado Shale Of North-Central Montana, Higbee G. Williams, David P. Wilson

Bachelors Theses and Reports, 1928 - 1970

The use of foraminifera in the determination of geologic age, and in the correlation of strata, is one of the most important techniques in oil field stratigraphic studies. The petroleum industry in many regions relies on these microscopic life forms to determine the positions of oil-bearing horizons and to determine the tops of beds. In northern Montana the Colorado group of strata, a series of about 2,000 feet of dense, dark similar shales, is known to contain foraminifers.

Geology Of The Hagan Coal Basin, Earl P. Harrison

Earth and Planetary Sciences ETDs

This study was undertaken with the foremost objective of determining the stratigraphy and structure of the area, and correlating it with known surrounding areas.

The method of study was through geologic mapping in the field. The formational contacts, faults and other features were studied in the field with the aid of aerial photographs. The sections were measured in the field by hand-leveling with a Brunton compass up across the exposures. The lithology of the formations was studied as the sections were measured. The base map was taken from a planimetric map prepared by the Soil Conservation Service from aerial photos. …

Paleoecology Of The Brachiopoda, Celia Faith Hendren

Earth and Planetary Sciences ETDs

The immediate concern of the writer in the preparation of this thesis is not so much to give long statistical lists of conclusions (unfortunately this type of material is exceedingly scarce), but to sift the readily available facts in print and prepare a brief history of the work already accomplished on living and fossil Brachipoda. Where possible, there will be a discussion and evaluation of the views presented by different authors.

Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd

Bachelors Theses and Reports, 1928 - 1970

Plane table and pacing methods were used in the mapping of the individual areas, but an automobile traverse was used to tie the independent areas into a composite group that would be useful for the entire zone. All land marks, section corners, roads, fence lines, drainage, and geologic features were plotted in the field and later transferred to a master map.

Correlation Between Electric And Lithologic Characteristics In Four Wells In San Juan County, New Mexico, Edward C. Beaumont

Earth and Planetary Sciences ETDs

The primary objective of the problem is to relate electric characteristics to lithologic characteristics in four wells in San Juan County, New Mexico. The secondary objective is to decipher stratigraphic correlations between wells. The wells, in San Juan County, are geologically located in the San Juan Basin, a structural basin in the Colorado Plateau. The formations range in age from Paleozoic Cambrian (?) to Cenozoic Recent. The boundaries of the Basin are ill-defined and have shifted throughout the history of the area.

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?

Paragenesis Of The Ores Of Poughkeepsie Gulch, San Juan Mountains, Colorado, Leon T. Silver

Earth and Planetary Sciences ETDs

It is the purpose of this study to supplement the recognized geologic field relations with a laboratory study of the mineral assemblage of the area and its paragenesis. It is hoped that the results may be employed in amplifying the knowledge of the origin of ore bodies in Poughkeepsie Gulch. The work as presented in this thesis consists of a description of the general mineralogy, descriptions and analyses of the ores by mine suites, and conclusions based upon the observed paragenesis. This material is preceded by introductory remarks on the source of data, previous work, and geologic setting.

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

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.

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.

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.

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.

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

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.

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.
