Daibase Sill Comanche County, Oklahoma, Jean A. Hardesty

Bachelors Theses and Reports, 1928 - 1970

The mechanics of intrusion and the processes involved are becoming of more and more interest to con­temporary geologists, because most of our mineral deposits are associated with igneous intrusions, and unknown-outcropping deposits are thought to be a thing of the past. If, by studying these pro­cesses, we could understand why some igneous masses are barren, while others of similar composition carry economic mineral deposits, geological prospecting for hidden mineral concentration would see a new era.

The Livingston Formation Of The South Boulder Area, Nelson A. Jones

Bachelors Theses and Reports, 1928 - 1970

The Livingston formation is a thick succession of late Cretaceous lava flows, tuffs, and bedded water-laid volcanic detritus 200 miles long and 100 miles wide lying along the eastern margin of the Rocky Mountains in western Montana from Augusta to Yellowstone Park. It differs markedly within short distances in lithologic character and sequences, and the total thickness may exceed one mile in some places.

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.

The Potash Status Of Utah Soils, Sukhendu Bikas Chaudhuri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Potassium is one of the essential plant nutrient elements. It is used by plants in the synthesis and distribution of carbohydrates (25)² and in the formation of proteins and oils. Potassium also seems to exert many of its effects by influencing enzymatic activity in cells.

Potassium occurs as the monovalent cation on plant cells and undoubtedly exerts important effects upon such phnomona as the permiability of the cytoplasmic membranes and hydration of protoplasma. Plants assimilate potassium either from the soil solution or directly from the exchange complex.

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. …

The Frost-Moved Rubbles Of Jumbo Dome And Their Significance In The Pleistocene Chronology Of Alaska, Clyde Wahrhaftig

United States Geological Survey: Staff Publications

Jumbo Dome, a prominent landmark on the north side of the Alaska Range, is a small body of intrusive andesite surrounded by schist and by poorly consolidated sediments of Tertiary age. Frost-moved rubbles, consisting of coarse andesite blocks, almost completely mantlethe dome and have advanced outward from it across a gently sloping terrain for distances as much as 1 ¼ miles. Several different periods of rubble development are recognized, based on the amount of vegetal covering of the deposits, the preservation of their surface forms, and their degree of erosion by fluvial processes. The rubbles are not now moving and …

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.

Bulletin of the University of Nebraska State Museum (1924–2023)

This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.

Geology And Mineralization Of The Minerva Mine No. 1, Hardin County, Illinois, Matthew Peter Nackowski

Masters Theses

"This study originally was undertaken to describe the witherite identified in specimens collected at the Minerva Oil Company Mine No. 1, Hardin County, Illinois. The original specimens of witherite were collected on October 25, 1948, by Charles E. Tothill, while on a senior trip through the fluorspar mine. The witherite was identified by Dr. O. R. Grawe, Chairman of the Geology Department, Missouri School of Mines, Rolla, Missouri, to whom the specimens were presented. Dr. Grawe suggested that the writer visit the southern Illinois fluorspar area to determine the occurrence and distribution of the witherite. This mineral had been described …

Colgrove Butte is a flat-topped erosional remnant with a cap of rock area of approximately 0.845 square miles, rising about 200 feet above the surrounding Missouri Plateau in northwestern Hettinger County, North Dakota. Its upper portion consists of flat lying fresh water deposits of White River (Oligocene) age, containing beds of hard limestone, marls, argillaceous limestones, calcareous clays, clays and sands. It is everywhere covered by a mantle of top soil 6 inches to 3 feet 6 inches thick. Below this topsoil, extending over approximately two-thirds of the caprock area of the butte, is a bed of hard limestone averaging …

Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter

Bulletin of the University of Nebraska State Museum (1924–2023)

PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …

Studies In Quantitative Paleontology: I. Some Aspects Of The Theory And Practice Of Quantitative Invertebrate Paleontology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

For some time there has been a noticeable trend toward a more strictly quantitative outlook in paleontology. In view of many special circumstances encountered in dealing with fossil material, there is a rather extended consideration here given to the theoretical background of the quantitative method as applied to fossil invertebrates. First there is a consideration of the relations between sampling theory and paleontology. This is followed by a discussion of variability in populations and the problem of inference from sample to population. A consideration is next given to the species concept and a comparison of the units which can be …

The Possibility Of A Land Bridge Across Nebraska In Mississippian Time, E. C. Reed

Department of Earth and Atmospheric Sciences: Faculty Publications

The lithologic and paleontologic differences between the Mississippian sediments of the Mid-Continent region and those of the northern Rocky Mountain and Black Hills regions suggest either that the Mississippian seas were not directly continuous between these two regions or that sea connections were greatly restricted. The purpose of this paper is to present and analyze the available subsurface data in Nebraska and surrounding states in the light of this problem. The study is primarily lithologic. Mississippian sediments are known to be widely distributed in the subsurface of much of Iowa and Kansas, in southeastern and extreme southwestern Nebraska, and in …

Mississippian-Pennsylvanian Boundary Problems In The Rocky Mountain Region, James Steele Williams

United States Geological Survey: Staff Publications

A variety of paleontologic and stratigraphic problems are presented by rocks near the Mississippian- Pennsylvanian boundary in the central and northern Rocky Mountains. Stratigraphic sections of these rocks show diverse interpretations of fundamental concepts of stratigraphy and paleontology. In many places where Upper Mississippian rocks directly underlie Pennsylvanian rocks it is difficult to determine the precise location of the boundary between these units. Formations that straddle the boundary are very useful and satisfactory over large areas. Most geologists use various types of lithologic criteria to distinguish formations, but some appear to rely mainly on faunal data, unconformities, or attempts to …

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.

A Petrographic Study Of The Lower Madera Limestone In Central New Mexico, Rose B. Johnson

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.

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.
