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.

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 …

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

Bachelors Theses and Reports, 1928 - 1970

The Golden Sunlight Mine is in the northern part of the Cardwell mining district on the eastern slope of a small range that rises by a series of benches to an elevation of 7,200 at a point five miles east of the town of Whitehall in Jefferson County.

A Study Of Solders, John D. Prater

Bachelors Theses and Reports, 1928 - 1970

The purpose of this paper is to furnish a qualitative method of comparing the degree of wetting of various solders upon different plate metals when several fluxes are used.

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.

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.

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.

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

Bulletin of the University of Nebraska State Museum

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

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.

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.
