Stratigraphy and Paleontology of the Eagle Formation in Montana and Adjacent Areas

A conspicuous two hundred and fifty foot sandstone of central Montana, known as the Eagle Formation, constitutes part of the some five thousand feet of Cretaceous sediments in the state. It stands out in steep cliffs which stretch for many miles in the outcrop area from Wyoming to Canada.

The Beneficiation of Montana Silver Star Chromite Ore

It is known that there are large deposits of chromium ore in Stillwater and Carbon Counties in South-Central Montana. The late James F. Kemp of Columbia University, stated in 1928, that these were the largest chromium deposits in the United States and probably in the world, although they were not considered of commercial grade as compared with foreign ores.

Report of Investigation on the Physical Characteristics of the Oil Sands from the Cut Bank Field, Montana

The purpose of this research was to study the physical characteristics, mainly, porosity and permeability of the oil sands from the Cut Bank field, Glacier County, Montana. In so doing, a better understanding of the relation­ship of these physical characteristics to one another and to the pool itself could be obtained.

Mineral Occurences in Certain Pegmatite Dikes in Southwestern Montana

Pegmatite dikes are rather common in occurrence in parts of southwestern Montana, particularly in a region to the east of the Tobacco Root range 50 to 75 miles southeast of Butte.

Upper Mississippian Faunas of Western Montana

The author has made a study of an assemblage of fossils from the Blacktail Range near Dillon Montana with the purpose in view of attempting a correlation of that group with the fauna of the Big Snowy Group. Fossils have also been obtained from a limestone formation in northwestern Montana and from four different areas in the Amsden formation in central and western Mont­ana.

Geologic Field Mapping in an Area Eight Miles North of Three Forks, Montana

The Three Forks are includes parts of Jefferson, Madison, Broadwater Pond Gallatin counties, Montana. Sedimentary formations lie at the surface nearly everywhere in the area, and the rugged surface topography has been developed through the folding and tilting of these formations and their dif­ferential erosion.

Mineralogy and Genesis of the Vermiculite Deposits at Libby, Montana

The problem considered in this report is one of the mineralogy and mode of formation of the extremely pure, large bodies of vermiculite. Mineralogically the ultrabasic intrusive, with which the economic mineral is associated, presents an array of rather unusual minerals. The determination of these minerals, their associations, and the sequence of alteration that lead to the formation of the vermiculite bodies, constitutes the problem.

Geology of Iron Deposits at Princeton Montana and Economic Aspects of Iron Ore in Montana

The purpose of this paper is to introduce to the reader, an iron deposit in the Princeton district, about 19 miles northeast by highway from Philipsburg, Montana. Heretofore there has been no written literature on this deposit. It is also intended to investigate the economic possibilities of iron ore in general in the State of Montana.

Induction Furnace Smelting of Montana Chromite

In 1939 the total world production of crude chromite was approximately 1,167,000 metric tons; of which the United States produced only 3,672 metric tons and imported over 317,500 metric tons. Imports came mostly from the Philippine Islands, Cuba, South Africa, and Rhodesia.

An Active Learning Module for an Introduction to Software Engineering Course

Many schools do not begin to introduce college students to software engineering until they have had at least one semester of programming. Since software engineering is a large, complex, and abstract subject it is difficult to construct active learning exercises that build on the students’ elementary knowledge of programming and still teach basic software engineering principles. It is also the case that beginning students typically know how to construct small programs, but they have little experience with the techniques necessary to produce reliable and long-term maintainable modules. I have addressed these two concerns by defining a local standard (Montana Tech Method (MTM) Software Development Standard for Small Modules Template) that step-by-step directs students toward the construction of highly reliable small modules using well known, best-practices software engineering techniques. “Small module” is here defined as a coherent development task that can be unit tested, and can be car ried out by a single (or a pair of) software engineer(s) in at most a few weeks. The standard describes the process to be used and also provides a template for the top-level documentation. The instructional module’s sequence of mini-lectures and exercises associated with the use of this (and other) local standards are used throughout the course, which perforce covers more abstract software engineering material using traditional reading and writing assignments. The sequence of mini-lectures and hands-on assignments (many of which are done in small groups) constitutes an instructional module that can be used in any similar software engineering course.

An Investigation of the Ores of the Big Seven Mine, Neihart, Montana

During the course of this investigation of the ores of the Big Seven mine, Neihart, Montana, the writer has attempted, through a mi­croscopic study of polished sections, to ascertain the hypogene or supergene character of the ore minerals present in the ore suite.

Chromite Deposits Near Red Lodge and Silver Star, Montana

The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest rail­road point. Lenses of chromite are exposed by pits and trench­es, which average approximately 36% chromic oxide.

Testing and Concentration of a Low Grade Gold Ore from Marysville, Montana

The purpose of this thesis was to investigate and attempt to concentrate low grade cyanided tailings rejected from the old Montana Mining and milling Company's mill situated 4 miles below the town of Marysville, Montana.

Shaping a Bright Future for Montana Tech: Developing State, National and Global Leaders in Resource Sectors

Presentation by Leigh W. Freeman. Rachel Carson's book Silent Spring published in 1962 marked the birth of concepts leading to the development of mineral resources with a balance of economic, environmental and social imperatives. Montana plays a special role in this story. It is 'the last best place.' As such it can serve as a bell-weather state for Carson's revelations. Consider: Butte as a poster child for legacy problems resulting from resource development under solely economic imperatives; and Montana as a first-adapter in 1971 of state environmental laws based on imperatives heralded with Silent Spring. What better place is there to educate and develop leaders and incubate the future of resource development in global sustainability?

Coal in Montana

Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 41000,000.00 annually.
