Geology Of The Middle Member Of The Bakken Formation In Divide County, North Dakota, Mandy Brewer
Geology Of The Middle Member Of The Bakken Formation In Divide County, North Dakota, Mandy Brewer
Graduate Theses & Non-Theses
The Upper Devonian-Lower Mississippian Bakken Formation of Williston Basin is a large unconventional oil and gas play consisting of a lower shale member, a middle member, and an upper shale member. The middle member is a production target because it contains porosity and petroleum expelled from the shale members around it. Variable production and sweet spots of the Bakken in the study area of Divide County, ND and 15 miles around Divide County in the USA prompted a closer look at middle member Bakken sediments. For this study, 606 wells were correlated and thin sections from two wells located 10.17 …
Subsurface To Surface Correlation Of The Tensleep Sandstone In The West Flank Of The Pryor Mountains In Carbon County, Montana, William B. Rhyne
Subsurface To Surface Correlation Of The Tensleep Sandstone In The West Flank Of The Pryor Mountains In Carbon County, Montana, William B. Rhyne
Graduate Theses & Non-Theses
The Pennsylvanian Tensleep Sandstone is an eolian and nearshore marine/sabka quartz arenite unit with prominent outcrops along the western Pryor/Bighorn Mountain front east of Red Lodge, MT. Regionally, the formation represents one of the largest ergs in the global geologic record. High permeability makes it an important oil and gas reservoir and aquifer in south central Montana and throughout much of Wyoming. The Tensleep Sandstone’s high percentage of quartz content and grain roundness, due to its eolian origin, makes it a prospective source for natural proppant sand.
Three continuous 4-inch cores were obtained during a cooperative project between Montana Tech …
A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie
A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie
Bachelors Theses and Reports, 1928 - 1970
Chromite, a strategic mineral, is being consumed in ever increasing quantities in the United States today. Although the United States imports practically all of the chromite that is being consumed, it is gradually becoming necessary to exploit the low-grade deposits that are located within the United States, and also the low-grade deposits of Canada.
An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach
An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach
Bachelors Theses and Reports, 1928 - 1970
Many fine-grained igneous rocks, basaltic and felsitic in character, are difficult to classify. In numerous cases, it is impossible to classify these types of rocks by quick methods of identification. It was hoped at the beginning of this study that refractive indices of glasses formed by quick artificial fusion of samples from selected suites of igneous rocks would show a close correlation in chemical composition.
Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price
Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price
Bachelors Theses and Reports, 1928 - 1970
For many years the study of sediments has been a major problem in the field of geology. Especially is this true of the branch of sedimentology known as grain-size distribution. Throughout the years many classical experiments have been performed and procedures evolved from them, all with the purpose of a better and easier determination of the grain-size distribution of fine sediments, particularly the clays.
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.
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.

Bachelors Theses and Reports, 1928 - 1970
The following evaluation of the mineral resources of the University Land-Grant lands has been made from an office study of geologic maps and published reports, and from a rather thorough knowledge of the geology of the state by the writer after 23 years of experience in the state.

A Preliminary Study Of The Ostracoda Of The Big Snowy Group, Mississippian, Of Montana., John C. Rabbitt
A Preliminary Study Of The Ostracoda Of The Big Snowy Group, Mississippian, Of Montana., John C. Rabbitt
Bachelors Theses and Reports, 1928 - 1970
In the field, samples were taken vertically and horizontally along the various outcrops in different sections of central and south-central Montana. At important localities the samples were taken about every half-foot vertically; in other sections they were taken every few feet.
Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy
Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy
Bachelors Theses and Reports, 1928 - 1970
Although considerable work has been undertaken by some prominent geologists, the best known of which is that of Paul Billingsley and J. A. Grimes', in investigating the ore deposits of the Boulder Batholith and surrounding area, there has not been any complete microscopic investigation of these deposits, as a whole, published in the literature. With this in mind it was suggested to the writer by Professor Paul A. Schafer, of the Montana School of Mines, that a microscopic study of the ores of this region would be a worthwhile geologic problem.
It was thought that the mineral association and the …
