An Investigation Of The Application Of Photoelastic Coatings To Soil Studies, James Kenneth Meisenheimer

Masters Theses

"The purpose of this investigation was to determine if photoelastic coatings could be adapted to soil systems and used as a workable tool for analyzing deformation and stress distribution. The required physical properties of a photoelastic coating on soil is discussed and a number of photoelastic materials are investigated as possible soil coatings. Mixing procedures, coating application techniques, curing methods, testing procedures, and results are discussed for gelatin and several plastics. Compacted soil samples and extruded soil samples from a Vac-Aire extrusion device were coated with reflective and photoelastic coatings and then loaded in an unconfined compression machine. The stress …

A Photoelastic Study Of The Stresses Around An Underground Opening And Its Support System, Alphonse C. Van Besien

Masters Theses

"The stress conditions around openings in rock have long been of interest to the field of rock mechanics. The purpose of this investigation was to determine the stress distribution around an opening with a rib and wall-plate support system. A photoelastic model of the opening (a modified horse-shoe section) was loaded in the centrifuge to determine the effect of body loading. Both the tangential stress and the stress within the rock bench, due to the opening, were determined. The stress conditions within the bench were examined using simulated ribs and a loading frame. Application of the data is discussed, as …

An Aggregate Quality Investigation Of The Meramec River Gravels, Kadri Ercin Kasapoglu

Masters Theses

"This thesis represents a study which was made to evaluate and interpret the downstream variations in the quality of the Meramec River gravels as coarse aggregate for concrete. Since gravel deposits constitute a valuable resource for a region, it is desirable that extent and quality variations of these deposits are known. It was hoped that an evaluation of certain properties of the Meramec River gravels would assist in determining the value of the Meramec River as undeveloped aggregate source by indicating the relative quality of the gravels from alternate sites of the river. For the purpose of this investigation, representative …

Trace Element Content Of Magnetites And Hematites, Southeast Missouri Iron Metallogenic Province, Usa, Geza Kisvarsany, Paul Dean Proctor

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Six major and numerous smaller Precambrian iron deposits of mag-matic origin occur in the volcanic rocks of the Southeast Missouri Iron Metallogenic Province in an area approximately 70 miles long and 40 miles wide. The Precambrian igneous complex is composed of mainly high silica, with some intermediate, volcanic rocks intruded by granitic rocks and some diorites and gabbros. Biotite schists occur locally. Some of the volcanic and intrusive rocks are characterized by an unusual abundance of alkali metals. Local enrichments in fluorite, calcite, and iron oxides are present. The shapes of the iron deposits range from massive tabular to irregular. …

Variation In Gold Content Of Minerals Of The Marysville Quartz Diorite Stock, Montana, Erwin J. Mantei, Arthur H. Brownlow

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Neutron activation analysis for gold has been carried out on 135 mineral samples from throughout the Marysville stock with the following results: (1) the gold content of 44 biotite ranges from 0·002 to 0·924 ppm with an average of 0·076 ppm; (2) 37 hornblende samples gave a range of 0·003-0·823 ppm and an average of 0·100 ppm; (3) for 44 magnetite samples the range was 0·003-0·329 ppm and the average 0·037 ppm; (4) 10 quartz-feldspar samples varied from 0·006 to 0·176 ppm with an average of 0·065 ppm. High gold values mainly occur near the edge of the stock and …

Hydrologic Characteristics Of Shallow Bedrock Aquifers In The Vicinity Of Norman Creek, Central Phelps County, Missouri, Michael A. Nawrocki

Masters Theses

"Groundwater is becoming increasingly important as a source of water supply in the United States. Consequently, the prediction of well yields is a vital concern. In order to predict the quantity of water which can be reduced from a given aquifer it is necessary to know the aquifer's hydrologic characteristics. Many theoretical formulae have been derived for determining the aquifer characteristics. To date, these formulae have been tested mainly on unconsolidated and clastic rock aquifers. It has never been shown that these formulae can also be consistently applied to carbonate aquifers which underlie regions of karst terrain. This paper summarizes …

Piezometric Levels And Shallow Aquifers, Dillon And Meramec Spring Quadrangles, Missouri, James Hugh Crouch

Masters Theses

"Little is known about groundwater in carbonate rock; quantitative data about limestone and dolomite aquifers are almost non-existent. Objectives of this study are: identification of shallow aquifers, and yield, occurrence, and piezometric level of groundwater in cherty dolomitic rocks in eastern Phelps County, Missouri. Area studied comprises of the 7.5-minute Dillon and Meramec Spring Quadrangles. The data used were derived from water well logs, interviews with well drillers and owners, and a previously available geologic map.

The Jefferson City, Roubidoux, and Gasconade formations are aquifers. Groundwater in the Jefferson City formation is perched. West and north of Dry Fork creek, …

Maximum Present Value Calculations With Digital Computers, James Boyd Robison

Masters Theses

"This paper discusses maximum present value calculations for a mineral property using digital computers. A semi-quantitative mathematical model to optimize operating conditions is considered. The model is based on a modified cash flow analysis. Many variables affect the solution, and their effect upon present value is described. Selected data (mining rate, costs, reserves, metal sales price, and others) for a hypothetical open pit copper mine are used in a set of solutions for present value. The results are discussed in detail. It is concluded that: (1) Digital computer methods are rapid and useful, (2) Changes in the mining rate, average …

The Effect Of Vegetation, Soil, And Rock Type On Runoff From Some Small Watersheds In Missouri, Anant Suthipas Narupon

Masters Theses

"A previous study of mean annual floods (Harbaugh, 1962) was based on watershed area, channel length, and channel slope of forty five small watershed in the State of Missouri. The present study investigates the effect of precipitation, soil distribution, vegetal cover, and underlying bedrock on annual peak rate of discharge. This study consists of statistical analysis by multiple correlations of additional quantitative data for nine of Harbaugh's forty five watersheds. Hydrologic data were obtained from the U.S. Geological Survey and U.S. Weather Bureau climatological publications. Distribution of vegetation was compiled from U.S. Department of Agriculture aerial photographs. Soil and rock …
