A Study On The Origin Of Banded Agate, James E. Driscoll Jun 1938

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.


Underground Stratigraphy Of Montana, Virgil R. Chamberlain Jun 1938

Underground Stratigraphy Of Montana, Virgil R. Chamberlain

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to study the subsurface stratigraphy of the state of Montana from information acquired from well logs, composite logs, and measured sections. Underground stratigraphy is important for the intelligent prospecting for oil, gas, or water. A knowledge of the strata beneath us can be gathered only by measurements of numerous outcrops or by deep drilling with careful sampling or logging of the formations passed through.


Study And Correlation Of Belt And Cambrian Arkoses Near Limespur, Montana, Ryan C. Mcnamee Jun 1938

Study And Correlation Of Belt And Cambrian Arkoses Near Limespur, Montana, Ryan C. Mcnamee

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.


The Jefferson Canyon Gypsum Deposit., Arthur Talpt Jun 1938

The Jefferson Canyon Gypsum Deposit., Arthur Talpt

Bachelors Theses and Reports, 1928 - 1970

Gypsum deposits are widespread geographically and are in many geo­logic formations. Ordinarily their character and origin, for the most part sedimentary, are not difficult to ascertain. Near Lewis and Clark Caverns, east of Whitehall, Montana, occurs a deposit of gypsum unique in many re­spects.


Alkali Leaching Of Antimony Sulphide And Electrolytic Recovery Of Antimony From The Resulting Leach Solution, Vincent J. Andrews May 1938

Alkali Leaching Of Antimony Sulphide And Electrolytic Recovery Of Antimony From The Resulting Leach Solution, Vincent J. Andrews

Bachelors Theses and Reports, 1928 - 1970

It is the purpose of this investigation to obtain some insight into optimum conditions for leaching Stib­nite with sodium hydroxide solution and also to steady the factors affecting the electrolysis of the resulting solution.


Age Hardening Of Silver-Platinum Alloys, Robert A. Wilson May 1938

Age Hardening Of Silver-Platinum Alloys, Robert A. Wilson

Bachelors Theses and Reports, 1928 - 1970

The alloy system selected for study was the binary alloy of platinum and silver. An examination of the various silver alloy diagrams revealed that of several possible alloys, the silver platinum was the most suit­able with regard to solubility.


Electrolytic Recovery Of Copper And Zinc From Brass., V. Kent Loughran May 1938

Electrolytic Recovery Of Copper And Zinc From Brass., V. Kent Loughran

Bachelors Theses and Reports, 1928 - 1970

The reclamation of metals from scrap is becoming increasingly important in the metallurgical industry. Copper, because it does not corrode readily and is electronegative to most common metals, is peculiarly adapted to reclamation.


Magnesium - Tellurium By Powder Methods, George Gale May 1938

Magnesium - Tellurium By Powder Methods, George Gale

Bachelors Theses and Reports, 1928 - 1970

Today considerable work is being done in the compressed metal powder field which is gradually ob­taining prominence as a valuable branch of metallurgy. The mass of data, however, has led to many different ideas on the results of sintering.


Geology And Ore Deposits Of The Golden Messenger Mine, Lewis And Clark County, Helena, Montana., John C. Archibald Jr. May 1938

Geology And Ore Deposits Of The Golden Messenger Mine, Lewis And Clark County, Helena, Montana., John C. Archibald Jr.

Bachelors Theses and Reports, 1928 - 1970

The Golden Messenger Mine which is approximately twenty-three miles northeast of Helena, Montana, near York, on Trout Creek, has long presented several problems of both theoretical and practical interest.


The Geology And Ore Deposits Of Jardine, Montana, Wolter Duykers May 1938

The Geology And Ore Deposits Of Jardine, Montana, Wolter Duykers

Bachelors Theses and Reports, 1928 - 1970

The subject to be covered by this paper is based upon field study made during a six week stay at Jardine. The work began on June 19, 1937 and ended on July 31 of the same year.


A Rapid Determination Of Small Amounts Of Lead In Zinc, George T. Hanson May 1938

A Rapid Determination Of Small Amounts Of Lead In Zinc, George T. Hanson

Bachelors Theses and Reports, 1928 - 1970

This investigation, carried on in the metallur­gical laboratories at the Montana School of Mines, was undertaken with the desire to work out a rapid method for the estimation, or the determination, of the amount of lead in zinc.


The Electrodeposition Of Manganese From Certain Aqueous Solutions., William C. Wallace May 1938

The Electrodeposition Of Manganese From Certain Aqueous Solutions., William C. Wallace

Bachelors Theses and Reports, 1928 - 1970

Manganese has been successfully electrodeposited from aqueous solutions in past years by several work­ers in electrochemical and electrometallurgical fields.

The present work was concerned, primarily, with investigation of electrodeposition from solutions which are commercially obtainable from the hydrometallurgical or pyrometallurgical treatment of the low grade mangan­ese deposits of this country.


The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt Feb 1938

The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt

Bachelors Theses and Reports, 1928 - 1970

Morrison Cave is located about 50 miles southeast of Butte, Montana. It was named after the man who discovered it. Later it was taken over by the State and renamed Morrison Cave State Park. Recently the government with the aid of the Civilian Conservation Corps has built a new road to the cave and has made the interior more accessible. The name of the cave is now Lewis and Clark Cavern National Monument.
