The Pre-Jurassic Surface Of Montana., G. Fay

Bachelors Theses and Reports, 1928 - 1970

It has long been known that, prior to the deposition of Jurassic sediments, Montana was subjected to an intensive period of erosion. Mention of this may be found in numerous reports, especially those dealing with western Montana.

Electrolytic Manganese, George T. Derana

Bachelors Theses and Reports, 1928 - 1970

The production of metallic manganese by electrolysis is of potential value for the recovery of this strategic metal from domestic deposits. These deposits are largely unsuitable for the production of ferromanganese, but they are amenable to low-cost leaching processes.

Igneous Rocks Of The Jardine And Crevasse Mountain Mining Districts., Ray E. Gilbert

Bachelors Theses and Reports, 1928 - 1970

It is surprising to learn that so large a variety of igneous rocks is present in the Jardine and Crevasse Mountain mining districts, a region that is generally thought of as consisting principally of schists.

The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis

Bachelors Theses and Reports, 1928 - 1970

The increase in hardness is attributed to the manganese silicide being precipitated from solid solution and deposited between crystal planes. The subsequent softening which occurs on prolonging the period of reheating is believed to be due to an agglomeration of the dispersed hardening agent.

Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart

Powder Metallurgy, Cecil R. Waldron

Bachelors Theses and Reports, 1928 - 1970

The metal powders may be produced in a number of different ways. In metals where the intercrystalline material is brittle enough, they may be ground in a ball mill or eddy mill. The fineness of such a powder is more or less controlled by the grain size of the original metal.

Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In connection with investigations of runoff and erosion in the Great Plains an attempt has been made by means of artificial applications of water to determine certain principles concerning the effect of different soils and soil conditions on runoff and soil erosion. Such information is needed in planning all field operations dealing with soil erosion and moisture control. It is also needed in connection with watershed studies that are being established in the Central Great Plains, dealing with runoff and flood flows from larger areas. The method employed makes it possible to obtain comparable data on a wide range of …

Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That the higher valleys of the Wasatch Mountains were occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows in a rough way the extent of the glaciated areas in the Central Wasatch (11 ). In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of …

Geology Of A Portion Of The Bull Mountain Range Jefferson County, Montana, Thomas A. Greene

Bachelors Theses and Reports, 1928 - 1970

Work was first done on a known section, the south Boulder Section, in order to familiarize the student with the formations. Most of the area was mapped by plane table and telescopic alidade, general features being surveyed by automobile traverse and a pacing traverse.

A Report Of The Geology Of The Golden Sunlight Mining District, Roy A. Mccready

Bachelors Theses and Reports, 1928 - 1970

This paper is a report of a geological survey made of an area of approximately fifty square miles lying Northeast of Whitehall, Montana, in the region of the Golden Sun­light Mine. The survey was made by a field party consisting of twenty-three members of the senior class of the Montana School of Mines.

An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra

George E. Condra Publications

Nebraska is well endowed with important natural resources, such as stone, clay, sand, soil, water, prairie, forests and wildlife. However, soil and water are our basic heritage because they, more than other resources, support native life, agriculture, industry, and social development.

An Outline Of Nebraska's Industries, George E. Condra

George E. Condra Publications

The principal industries of Nebraska are summarized into the following groups: mineral, agriculture, manufacturing, transportation and publishing, and trade or mechandizing.

South Moccasin Kaolin Deposit, Walter Everly

Bachelors Theses and Reports, 1928 - 1970

Kaolin has never been considered an important economic mineral in Montana. Deposits of Kaolin in this state are not described in the literature and apparently very few deposits have been found.

Life History Of The Ginko Petrified Forest Or The Autobiography Of An Ancient Oak Tree, George F. Beck

Geological Sciences Faculty Scholarship

An account of a fossilized log at Ginkgo Tree State Park written by the man who discovered the fossil trees and established there were Ginkgo trees in North America in the distant past.

The booklet is written from the perspective of one of the fossilized trees, tracing the geologic forces that led to it becoming a fossil.

A New Giant Camel Gigantocamelus Fricki, Gen. Et Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936.

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum (1924–2023)

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

Classification Of The Tertiary System In Nebraska, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

This paper represents the results of almost continuous research by the Nebraska State Geological Survey on Tertiary stratigraphy in Nebraska during a perIod of more than 10 years, with special attention to the present acceptable stratigraphic nomenclature. Cogent reasons are presented for the retention of such well-known names as White River, Arikaree, and Ogallala, all now redefined and elevated to group ranking. “Loup Fork” and “Loup River,” "Nebraska beds", and “Republican River" are considered obsolete. The application of fossil seed zones to problems of correlation is noted. The table of Tertiary Formations of Nebraska summarizes the Tertiary stratigraphy in Nebraska.

The Nebraska State Geological Survey And The "Valentine Problem", Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

The Nebraska State Geological Survey is primarily concerned with the stratigraphic classification of the Tertiary lithologic units in this state. When the stratigraphic relationships are fully understood, the faunas can be properly and correctly related and named, whether the stratigraphic names or others are used. It should be understood that this survey, in determmmg its acceptance of stratigraphic names on the basis of priority, is making every effort to differentiate names which have been applied in a strictly stratigraphic sense from names which. while they may be older, were applied in only a geographic or faunal sense and have only …

Additions To The Late Tertiary Floras Of The Pacific Northwest, George F. Beck

All Faculty Scholarship for the College of the Sciences

The purpose of this paper and those which will follow, is to present new types of flora found in several older leaf localities of the Pacific Northwest. A study will also be made of a number of new localities as yet not reported upon in the literature. The present paper refers to several new species found at the Bull Quarry, Ellensburg, and the Brickyard locality, Spokane, Washington. Both sites have been studied and reported upon in the past, as noted in attached bibliography.

Washington Petrified Forests-Ginkgo Exotic Forest, George F. Beck

All Faculty Scholarship for the College of the Sciences

Seven years ago we began our study of the Ginkgo Petrified Forest in Central Washington. This is in reality a series of forests occurring at various horizons in the Yakima ( and Wenas?) basalts throughout a vertical range of some 2,000 feet, and in a belt 150 miles long, and 50 miles wide, centering at Vantage on the Columbia River.

Bachelors Theses and Reports, 1928 - 1970

In the vicinity of Limespur, Montana, a siding along the Northern Pacific Railroad near Whitehall, Montana, occurs a characteristic type of arkose where­ in many small red mineral grains are distributed throughout the rock mass. It is in this respect that this arkose differs from other arkoses in the surrounding region.

A Study On The Origin Of Banded Agate, James E. Driscoll

Bachelors Theses and Reports, 1928 - 1970

Agate in any of its varieties presents numerous problems in regard to its origin. Many types have been described and their beauty elaborated upon, but little has been written concerning their formation and the problems involved. The genesis of agate implicates an amazing complexity of physical and colloid­al chemistry, as well as, various principles of geology.
