Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.

The Minerals Of New Mexico, Lee Mcguinness

Earth and Planetary Sciences ETDs

Inorganic bodies known as minerals make up, either in whole rock-masses or in isolated form, the material of the upper crust of the earth. Through the evidence furnished by this study of meteorites, we also infer that other bodies in the universe are made up of minerals, or at least those portions of them which are represented by meteorites.

Since minerals are, then, important in making up the observable part of the earth, a study of them is importance in any study of the earth. Because the variety of minerals occurring in New Mexico is large, it will be of …

A Metallographic Study Of Primitive Copper Work., John A. Alley

Bachelors Theses and Reports, 1928 - 1970

The field of archaeology and that of metallurgy appear to be widely separated and in no way related. Work done in recent years, however, tends to show that, in many ways, the metallurgist can supplement and enhance the information gain­ed by the archaeologist, at least in regard to those objects which have been made of metal.

Amherst Township, A Regional Study, Ruth C. Rockwood

Honors Papers

Amherst township was selected as the area to be studied because it was believed to be as nearly representative of the aspects of land and life in north central Ohio as any small area that could be found. It is located on a section of the Lake Plain which has somewhat parallel lines formed by three beach-ridges, and on the northern edge of the Glaciated Plain. Then, the quarrying of the world famous Berea sandstone gives somewhat of an individual aspect to the small towns within Amherst township.

The purpose of the paper is to describe the physical landscape, and …

The Sorption Of Fluoride Ion With Special Reference To Fluoride Removal From Potable Waters, Phillip W. West

Theses and Dissertations

The recent discovery that even very small concentrations of fluorides in drinking waters are sufficient to cause the serious dental dystrophy commonly known as mottled enamel, has around widespread interest and concern. Federal and State surveys have been conducted to determine the geographical distribution of the malady, and the fluoride contents of water supplies.

County dental surveys, conducted by the United States Public Health Department with the cooperation of local dentists, have located the regions throughout the country where mottled enamel is endemic and among these localities is an area in southeastern North Dakota and adjacent territory in South Dakota …

Fossil Bearing Basalts (More Particularly The Yakima Basalt Of Central Washington), George F. Beck

All Faculty Scholarship for the College of the Sciences

Such an overwhelming majority of the floral and faunal remains of the earth's crust have been yielded by rocks of sedimentary origin that generalized statements concerning the occurrence of fossils often neglect their more rare appearance in metamorphic and igneous rocks. In fact there is the temptation, after volcanic tuffs have been excluded as more or less sedimentary, to venture the positive assertion that by their very character igneous rocks are incapable of recording the presence of the life which may have existed at the time of their extrusion. As a result, most that has been written concerning fossil floras …

Conservation Of The Prehistoric Remains Of Nebraska, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

A RESOLUTION has recently been adopted by both houses of the Nebraska legislature to conserve the scientifically very valuable deposits of fossil and other prehistoric remains which occur in the state. This is not to be construed as an unfriendly move on the part of the sponsors of this act. The Nebraska Geological Survey welcomes serious scientific study and research within the state by all persons and institutions who seriously desire to investigate and collect for purely scientific purposes. There is no intention to restrict or curtail the collection of materials by properly accredited representatives of educational institutions and museums. …

A Comparative Pollution Study Of The Domestic Water Supply Of Warren County, Kentucky, Glenn Scott

Masters Theses & Specialist Projects

The domestic water supply of Warren County, outside of the city of Bowling Green, is obtained from deep wells and springs. The county is about evenly divided into a southern section of cavernous limestone and a northern section of mixed sandstone and limestone formations.

The wells of the southern cavernous limestone region receive water from unfiltered underground streams and lakes. Most of the wells of the northern region are drilled in sandstone and the water, in a majority of cases, is filtered through porous sandstone and shale.

The purpose of this study was to make a comparative pollution study of …

Attempted Proofs Of The Differentiation Of Magmas By Syntexis, Clifford Wendel

Bachelors Theses and Reports, 1928 - 1970

This investigation was an effort to obtain proof of the much disputed principle that most of the observed mag­netic differentiations have been due to the assimilation, or syntexis, of the intruded country rocks.

A Metallurgical Study Of Gold Ores, Alfred A. Bloom

Bachelors Theses and Reports, 1928 - 1970

Gold is widely distributed in the earth's crust in small quantities. Gold is found in nature in two forms; the element itself and the compound gold telluride. In all cases, silver in some proportion is an alloying constituent.

Electrolytic Recovery Of Copper And Zinc From Brasses, Thomas Barker Jr.

Bachelors Theses and Reports, 1928 - 1970

Reclaimed metals, or secondary metals, are becoming of great im­portance in the metal industries of the world. Secondary metals are an important factor in production. The increase in the secondary production of copper is due to many factors. One of these may be its permenance, that is, the metal does not corrode very readily. Another reason for increase in production is the high price paid for it.

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.

The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill

Bachelors Theses and Reports, 1928 - 1970

Careful examination of the literature available shows that the electrodeposition of manganese from various aqueous solutions has not been attempted to any great extent. The best method for the electrodeposition of pure manganese consists in the electrolysis of a solution con­taining manganous and ammonium sulphates.

The Staining Effect Of The Hydrochloric Acid-Chromate Trioxide Solution On The Minerals Of The Chalcocite-Stibnite-Galena Ternary System., John W. Johns Jr.

Bachelors Theses and Reports, 1928 - 1970

The object of this work has been to devise a method by which the different phases in the chalcocite-stibnite-galena ternary system may be identified. As the mineralogists have no precise methods for the identification of these phases, a hydrochloric acid-chromate trioxide staining solution was employed.

Occurrence And Origin Of Placer Gold In Montana, John K. Halse

Bachelors Theses and Reports, 1928 - 1970

From time immemorial man has used gold as a medium of exchange, a mea­sure of value, as jewelry and for ornamentation. Placer gold has led dir­ectly or indirectly to the settlement of lands, California and Alaska being the two best known examples. It has led the way to the discovery of other important mineral wealth, the discovery of the copper and silver deposits at Butte, Montana and the discovery of the silver deposits at Cripple Creek, Colorado being two good examples.

An Investigation Of The Properties Of Some Of The White Metal Alloys, William James Walsh Jr.

Bachelors Theses and Reports, 1928 - 1970

Although there is no standardized list of alloys, most investigators have, to avoid confusion, concurred in at least grouping the metals under several general heads. Precious metals: gold, silver and the platinum group; the light metals: aluminum and magnesium; the non-ferrous metals (excluding all steels and iron-base alloys); and the antifriction metals.

The Separation Of Tungstic Oxide From Scheelite And Its Subsequent Reduction With Hydrogen, Dave Jones

Bachelors Theses and Reports, 1928 - 1970

The largest known deposits of tungsten ores occur in the continuation of the Indo-Malayan Mountains, which extends through Burma, Malaya, China, Japan, and Chosen. Production of tungsten concentrates was started in 1910 in Burma, and in 1911 this country was the world's largest producer. China produced but little until 1916, but has since supplied over fifty per cent of the world's requirements.

Microscopic Study Of Montana Silver Ores., Edwin Johnson

Bachelors Theses and Reports, 1928 - 1970

A microscopic investigation of the Montana silver minerals was conducted. This study consisted mainly of identifying the silver and silver-bearing minerals and of determining their paragenetic rela­tionships. The increasing amount of research in which the reflecting microscope is employed is evidence of the great value of this method of approach in the solution of problems of paragenesis of the opaque minerals.
