A Case For University Credits For Industry's In-House Continuing Education Programs, Robert E. Carlile

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The minerals industries have long recognized the tangible and intangible returns from continuing education programs for their technical scientific and administrative personnel. 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 …

Trace Element Content Of Magnetites And Hematites, Southeast Missouri Iron Metallogenic Province, Usa, Geza Kisvarsany, Paul Dean Proctor

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Six major and numerous smaller Precambrian iron deposits of mag-matic origin occur in the volcanic rocks of the Southeast Missouri Iron Metallogenic Province in an area approximately 70 miles long and 40 miles wide. The Precambrian igneous complex is composed of mainly high silica, with some intermediate, volcanic rocks intruded by granitic rocks and some diorites and gabbros. Biotite schists occur locally. Some of the volcanic and intrusive rocks are characterized by an unusual abundance of alkali metals. Local enrichments in fluorite, calcite, and iron oxides are present. The shapes of the iron deposits range from massive tabular to irregular. …

Variation In Gold Content Of Minerals Of The Marysville Quartz Diorite Stock, Montana, Erwin J. Mantei, Arthur H. Brownlow

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Neutron activation analysis for gold has been carried out on 135 mineral samples from throughout the Marysville stock with the following results: (1) the gold content of 44 biotite ranges from 0·002 to 0·924 ppm with an average of 0·076 ppm; (2) 37 hornblende samples gave a range of 0·003-0·823 ppm and an average of 0·100 ppm; (3) for 44 magnetite samples the range was 0·003-0·329 ppm and the average 0·037 ppm; (4) 10 quartz-feldspar samples varied from 0·006 to 0·176 ppm with an average of 0·065 ppm. High gold values mainly occur near the edge of the stock and …

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 …

Crustacean Gastroliths From The Jackson Eocene Of Louisiana

School of Mines and Metallurgy Bulletins

Wechesia louisianae, n. sp., is described from upper Eocene beds at Montgomery, Louisiana. Second species of the genus, it extends the range of Wechesia Frizzell and Exline from Claiborne (middle) Eocene and validates the generic diagnosis.

Spilitic Rocks And Mineral Deposits

School of Mines and Metallurgy Bulletins

The principal results of research work on spilitic rocks and mineral deposits carried on since 1945 are briefly summarized. Emphasis is placed on the influence of the results on the theories of rock and ore genesis, particularly the change of "philosophy of exploration" based on the existence of hydromagmatic ore deposition. A re-classification of magmatic mineral deposits is offered.
