A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
Bachelors Theses and Reports, 1928 - 1970
The purpose of the investigation was to determine the most effective means of concentrating the manganese in the ore. The study was that of identification of the minerals present. This showed the presence of oxides of manganese and iron, and carbonates of calcium and manganese. Methods of investigation were planned to determined whether the ore could be concentrated effectively by gravity concentration methods.

The Pre-Jurassic Surface Of Montana., G. Fay
Bachelors Theses and Reports, 1928 - 1970
It has long been known that, prior to the deposition of Jurassic sediments, Montana was subjected to an intensive period of erosion. Mention of this may be found in numerous reports, especially those dealing with western Montana.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Bachelors Theses and Reports, 1928 - 1970
On the southern margin of the Boulder Batholith, about twenty miles south of Butte in the Highland Mountains, there are many miles of contact between the igneous and sedimentary rocks. As two kinds of igneous rocks and many different kinds of sedimentary rock are present, it is an excellent place for the study of contact metamorphism.

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.
