Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.

A Textural Analysis Of The Bedford Shale Of Lorain County, Ohio, Troy James Laswell

Honors Papers

Throughout the course of the school year 1947-48 the writer has collected specimens of the Bedford shale from various localities within Lorain County, Ohio. Textural and mineralogical analyses have been made of the specimens in order to determine the textural and petrologic variation between the two facies, and whether each of the facies was deposited under similar conditions.

Petrology Of The Upper Marietta And Hundred Sandstones In Southeastern Ohio, Wayne Dudley Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

A petrographic study was made of two Lower Permian (Dunkard Series) sandstones in southeastern Ohio. The sandstone members with which the investigation was concerned are the Upper Marietta sandstone and the Hundred sandstone. The study was made in order to determine the origin of the sandstones and the practicability of applying geologic methods to the grindstone industry. The results of the study indicate that although some of the constituents of these sandstones were derived from igneous and sedimentary source rocks, a relatively large amount of material was derived from metamorphic rocks. The detritus was transported from the east and deposited …

Mayflower, Renova Basin, And South Boulder Creek Areas, Howard Nickelson

Bachelors Theses and Reports, 1928 - 1970

The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener

University Studies (University of Nebraska) (1888–1984)

This investigation is essentially a geomorphological study of the lower Platte River Valley area in eastern Nebraska. The area comprises Saunders, Dodge, Washington, Douglas, Sarpy, and Cass counties. The area defined above is one of the most critically located of any for the study of the post-Kansan history of the lower Platte River Valley. It lies between the older till (Nebraskan and Kansan) borders to the west and the younger till (Illinoian, Iowan, and Wisconsin) borders to the east. Physiographic changes have therefore transpired in a strictly post-Kansan periglacial region. The Kansan till is the youngest in the area. The …

Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea

Bachelors Theses and Reports, 1928 - 1970

The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Re­fining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transporta­tion facilities, only the upper portions of a few lodes were exploited by the early miners.

Rugose Corals Of The Madison Group, William R. Paine

Bachelors Theses and Reports, 1928 - 1970

One of the best types of index fossils, and one which occurs most plentifully in the Madison group of formations in Montana, and yet, one which has been little studied, is the group of rugose, or cup, corals. Perhaps this group of fossils has not been studied in detail because their distinguishing characteristics are mainly internal, and labo­ratory preparation in the form of thin section or polished surfaces is necessary to bring out these characteristics.

Kibbey Sandstone In Montana, Glen Shean

Bachelors Theses and Reports, 1928 - 1970

Much attention has recently been given, by geolog­ists, to prolific water bearing horizon and a potent­ial oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some local­ities the sandstone is dry, and its identification in cut­tings from deep wells has in many cases proved difficult.

The Geology And Ore Deposits Of The Ruby Gulch Mine, Henry J. Roletto, John X. Combo

Bachelors Theses and Reports, 1928 - 1970

The Ruby Gulch Mine, owned and operated by the Ruby Gulch Mining Company, Zortman, Montana, is one of the most important low-grade gold producers in the state. Sit­uated in the Little Rocky Mountains, the mine has had an interesting history since its discovery shortly before the turn of the century.

An Investigation Of A Particular Weldment Failure, Byron Clow

Bachelors Theses and Reports, 1928 - 1970

Two sets of weld-test coupons, supposedly made under identical conditions, were submitted to this institution last year for approval and certification under the A.S.M.E. Welder's Qualification Code. The first set of coupons was unsatisfactory. The second set, made by the same operators one month later, was satisfactory.

Corrosion Testing Of Iron-Tin Alloys By The Salt Spray Method, Bernard T. Mcdonald

Bachelors Theses and Reports, 1928 - 1970

The purpose of this study was to determine the rela­tive rate of corrosion of iron-tin alloys containing low percentages of tin. Since in the world today, a great deal of work is being done to develop large tin deposits and new methods devised to treat these ores, it is possible that the metal will become abundant and will obtain a more important position in the metal industry.

The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill

Bachelors Theses and Reports, 1928 - 1970

The art of Powder Metallurgy deals with the preparation of metal powders and their utilization. As a more pertinent definition, the following has been suggest­ed: "Powder Metallurgy is the art of producing metal powders and shaped objects from individual, mixed, or alloyed metal powders, with or without the inclusion of non-metallic consti­tuents".

Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken

Bachelors Theses and Reports, 1928 - 1970

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.

Upper Cretaceous Sediment In Montana, Frank J. Frankovich

Bachelors Theses and Reports, 1928 - 1970

Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.

The Problem Of The Tensleep Sandstone, George D. Mccarthy

Bachelors Theses and Reports, 1928 - 1970

Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignifi­cant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ram­ifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undevel­oped natural resource of Montana.

Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair

Bachelors Theses and Reports, 1928 - 1970

The intensive postwar search for new petroleum horizons has resulted in widespread prospecting in the northern Great Plains. No commercial production has as yet been derived from Ordovician or Devonian rocks in Montana, but the relat­ively few tests that have penetrated to critical depths have disclosed encouraging conditions which merit further consider­ation, especially in Devonian strata.

Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland

Bachelors Theses and Reports, 1928 - 1970

Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.
