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 …

A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.

The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen

Bachelors Theses and Reports, 1928 - 1970

In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available.

The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929.

The rock specimens and much information as to their …

Geological Report Of Summer Field Trip 1928, Clarence A. Corry, Marcus Mccanna

Bachelors Theses and Reports, 1928 - 1970

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps.

The senior class of the Montana State School of MInes under the supervision of Dr. E.S. Perry performed the work, which covered an area in Madison County including South Boulder Creek, near Jefferson Island, the Silver Star Mining District, and the Alameda Mine, near Virginia City.
