These programs originate from the mutual desires of the employer to upgrade the professional competence of the employee and the employee's concurrent desires to keep abreast of new developments to review the state of the art of specialized subjects and to better qualify himself to compete in an every changing technology. In-house training and continuing education programs to provide such review and education for the employee are becoming a recognized function of companies comprising this industry. These company-sponsored …

Measurement Of The Surface Energy Of Rock By The Three-Point Bending Of Notched Beams, John Walter Corwine

Masters Theses

"In this investigation, the surface energy of a medium-grained igneous rock (Barre granite) was measured by breaking small, notched beams in bending. The technique was adapted from fracture toughness tests that have been used with metals and ceramics. The equations used for the calculation of surface energy were derived from several writers' equations for the stress intensity at the end of a notch in a beam subject to bending. Beam thickness, notch width and mineral occurring at the notch tip were evaluated for their influence on the calculated values of surface energy. The surface energy values obtained were used in …

Hydrologic Characteristics Of Shallow Bedrock Aquifers In The Vicinity Of Norman Creek, Central Phelps County, Missouri, Michael A. Nawrocki

Masters Theses

"Groundwater is becoming increasingly important as a source of water supply in the United States. Consequently, the prediction of well yields is a vital concern. In order to predict the quantity of water which can be reduced from a given aquifer it is necessary to know the aquifer's hydrologic characteristics. Many theoretical formulae have been derived for determining the aquifer characteristics. To date, these formulae have been tested mainly on unconsolidated and clastic rock aquifers. It has never been shown that these formulae can also be consistently applied to carbonate aquifers which underlie regions of karst terrain. This paper summarizes …

New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes)

School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleoichthyology.

Squirrelfishes ( " Holocentridae" of authors) are generalized forms in which evolutionary divergence of some mag nitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separate. at least since the middle Eocene.

A revised classification, based on available lines of …

Paragenesis Of The Primary Ores Of The Norwich Mine, Edward E. Scheitlin

Bachelors Theses and Reports, 1928 - 1970

The Norwich vein is thought to belong to the Anaconda vein system. It contains fairly large deposits of manganese. The study of 19 thin sections and 15 polished sections was made to determine the paragenesis of the vein minerals, which is: quartz-pyrite, rhodochrosite, quartz, minor rhodochrosite, quartz-pyrite-sphalerite, galena, freibergite and later quartz. Some supergene rhodochrosite was found and most of the silver minerals were found to be supergene origin.

Geology Of A Portion Of The Hand Mine, Argenta Mining District, Beaverhead County, Montana, John Thomas Richards

Bachelors Theses and Reports, 1928 - 1970

The Hand Mine is located in the Argenta Mining District near the town of Argenta. The area surrounding the Hand Mine is characterized by intense thrusting, folding, and igneous activity. The area mapped by the author is in the southeast portion of the mine and differs from the rest of the mine in that no commercial ore has been found. The writer concludes that the steep faulting and flatlying bodies are of two different ages, and that intense oxidation has altered the ore minerals to plumbojarosite.

Oxidized Copper Mineralization Along The Continental Fault Near Butte, Montana, Theodore H. Eyde

Bachelors Theses and Reports, 1928 - 1970

Located in the fault zone of the Continental fault near the western edge of Boulder batholith of southwestern Montana the oxidized copper deposits are developed by three open pit mines, one of which is a presently in operation. Copper has been deposited by descending cold solutions which have leached copper from the surrounding quartz monzonite and deposited within the crushed fault zone. Local high grade 'bunches' of ore occur along narrow limonite veins, remnants of primary sulfide veins which have been enriched by the descending cold solutions.

Uranium Occurrences In The Pacific Northwest, Charles Van Alstine

Bachelors Theses and Reports, 1928 - 1970

Uranium prospecting and production in the United States have been largely concentrated in the southwestern states, especially the plateau region of Utah, Colorado, Arizona and New Mexico. However, even with meager prospecting, numerous occurrences of uranium materials have been found in the Pacific northwest. These occurrences are in rooks ranging in age from pre-Cambrian Belt series to Tertiary volcanics and lake beds.

Geology Of An Area Near Montana City, Montana, Frank A. Crowley

Bachelors Theses and Reports, 1928 - 1970

The investigated area lies about five miles south of Helena, Montana, near the abandoned gold camp of Montana City. Topographically, the area reflects the sedimentary formations and the igneous rocks, quartz monzonite and rhyolite. Static recrystallization of the sedimentary rocks caused by the intrusion of the Boulder Batholith, along with deformation of sedimentary beds by pre-batholithic folding and by post-batholithic faulting have complicated the geologic picture.

The Placer Deposits Of The Siberia District (German Gulch), Montana, Ronald D. Karvinen

Bachelors Theses and Reports, 1928 - 1970

The original concept of this problem was to determine if hidden or buried placers existed past the terminal point of the extensive placering in the Siberia District. Several theories have been advanced for the sudden cessation of those placers. All are plausible, and are both for and against an extended placer. The past history relates that some $13,000,000 in gold has been produced in the area, therefore stressing a practical search for additional accumulation.

Geology Of A Mineralized Breccia "Pipe" Near Basin, Montana, James W. Allan

Bachelors Theses and Reports, 1928 - 1970

Located on the western flank of the Boulder batholith of southwestern Montana, the mineralized breccia "pipe" is opened by the Obelisk Mine. The intersection of two fault systems in the quartz monzonite of the Boulder batholith has provided the locus of the breccia "pipe". There is fairly conclusive evidence indicating that the present outcrop of the "pipe" lies only a few hundred feet below the former "roof" of the batholith.

Southwestern Extension Of The Pondera Field, Paul P. Garding

Bachelors Theses and Reports, 1928 - 1970

Oil was discovered in the Pondera field in June 1927 following work done by E.B. Emrick. The initial discovery well, located in section 17, T. 27 N., R. 4 W., was not a commercial oil producer. Its initial production being 3 barrels of oil and 3,500,000 cubic feet of gas per day. Rapid expansion followed until 1929, when the field reached its peak of production.
