Petrographic Analyses Of The Chepultepec Sandstones Of The Norris Reservoir Region, Tennessee, Chilton Eaton Prouty

Masters Theses

"The Norris Reservoir is located in northeastern Tennessee, in the Appalachian Valley. It includes all or portions of Anderson, Campbell, Claiborne, Granger, Knox, and Union counties. The area is shown by the map of Pate I. It is approximately thirty-five miles long in a northeast-southwest direction and about eighteen to twenty miles wide, in a northwest-southeast direction. The area is bounded on the northwest by the Cumberland escarpment and on the southeast by Clinch Mountain. The other boundaries are arbitrarily drawn near the town of Clinton to the southwest and near Tazewell to the northeast"--Introduction. Location and Nature of the …

Oil And Gas Resources, Jackson County, Missouri, Joseph Robinson Clair

Masters Theses

"The oil and gas production in Jackson County, though rather small, is nevertheless of considerable economic importance. A portion of the county has been rather thoroughly developed but the remainder has had little prospecting. In order to aid further development in the region the Missouri Geological Survey engaged in the mapping of all the known wells in the county as a basis for preparing a structural contour map of the area. In addition, a member of the Survey staff is stationed permanently in Kansas City to give assistance to the operators in the region and to collect the logs of …

The Paleozoic Stratigraphy Of Lorain County, Ohio, Edwin Hugo Wenberg

Honors Papers

During the course of the school year 1936-37 spent at Oberlin, which is situated near the center of Lorain County, Ohio, the writer had the opportunity to study the outcrops and to gather records of wells in this area.

A study of the strata of this county is confusing because the same rocks have been described under different formational names. Originally many of these strata were traced northward from type sections in central Ohio or westward from type sections near Cleveland. At a later date many of the strata were reclassified and assigned to formations which had been traced westward …

A Mechanical Analysis Of The Oriskany Sandstone In Northwestern Virginia, Selma G. Hirsh

Honors Papers

The primary purpose of this paper is to present specific data as a means of explaining the sedimentation conditions at the time of deposition of the Oriskany Sandstone. The data were obtained through the use of laboratory methods upon specimens taken from several outcrops in the vicinity of Monterey, Virginia (see Darton's U.S.G.S. folio No. 51). In addition to the presentation of objective results, the author has attempted to make tentative interpretations of them, based primarily upon textural and shape analysis of the sediment. The writer realizes that the investigation is inadequate in many respects, due to lack of time …

Determining Fossil Woods (Western Conifers), George F. Beck

All Faculty Scholarship for the College of the Sciences

In this paper we come to consider the problem of the coniferous woods. One cannot always recognize with certainty that a given wood is a conifer, yet in ninety percent of the specimens recognition is simple.

Remarkable West American Fossil, The Blue Lake Rhino, George F. Beck

All Faculty Scholarship for the College of the Sciences

Bidding for acceptance as fact, and for its place in the sun of fame and notoriety, we come now to the newly discovered fossil rhino animal mold of Blue Lake in Grand Coulee, central Washington. Not that fossil rhinos are rare or that their abundance in the Tertiary of America has waited until the present for revelation, is this fossil important. The feature in the Blue Lake rhino which taxes our credulity is the existence of the thing in what unquestionably must pass as once liquid basaltic lava. That anything organic could pass through the terrific heat and pressure of …

Determination Of Fossil Woods (Part V-Beech-Sycamore-Alder), George F. Beck

All Faculty Scholarship for the College of the Sciences

The group of woods considered in this paper are only superficially alike—no implication that they are closely related is intended. The beginner will almost certainly confuse the compound rays of these various woods with their annual rings.

The Control Of The Grain Size Of Tin., Robert D. Macdonald

Bachelors Theses and Reports, 1928 - 1970

The tin alloys of tellurium are extremely hard and have very great tensile strength. It was thought that the reduction of the rate of grain growth of tin with the addition of tellurium accompanied this hardening and strengthening and such way found to be true.

The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson

Bachelors Theses and Reports, 1928 - 1970

Rhenium properties offer many interesting possibilities, therefore any ores containing rhenium would be of considerable value. Its close relationship to manganese in the periodic table led to the belief that manganese ores would be an excellent place to search for the metal. Investigation of the literature of rhenium revealed that no ore was known to contain more than 0.001 per cent of rhenium.

The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr.

Bachelors Theses and Reports, 1928 - 1970

Carbon and carbonaceous material have been known to have a deleterious effect upon the cyanidation of gold and silver ores since the very beginning of the process. Organic matter is a common source of impu­rities in cyanide solution, its reducing effect being notorious.

The Electrical Conductivity Of The Copper-Aluminum Alloys., William W. Hintalla

Bachelors Theses and Reports, 1928 - 1970

Among the many aluminum alloys which have been studied are the binary copper-aluminum alloys. These have proven to be among the most useful of the alumi­num alloys thus far worked upon.

The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater

Bachelors Theses and Reports, 1928 - 1970

It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.

The Effect Of Temperature On The Rate Of Dissolution Of Gold In Cyanide Solutions Which Have A Constant Oxygen Content., Robert Currie

Bachelors Theses and Reports, 1928 - 1970

Since the development of cyanidation into a highly efficient process for treating gold ores, many papers have been written on its various aspects. Although, there has been much work done on it, the chemistry of the reaction is not yet completely understood.

The Electrowinning Of Copper From Roasted Sulphides, Thomas B. Linn

Bachelors Theses and Reports, 1928 - 1970

A hydrometallurgical process for the recovery of copper from flotation concentrates has long been con­sidered an attractive possibility. The object of such a method is to produce electrolytic copper without resorting to expensive matte smelting and converting.

Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank

Bachelors Theses and Reports, 1928 - 1970

The purpose of this research was to continue the work of Thomas Parker, who worked on the recovery of copper and zinc from brass during the school year l934 - 1935. Since there is such a wide variety of brasses made with usually a third alloying constituent, remelt­ed scrap is suitable only for castings of wide tolerance in specifications.

In this preliminary chart are shown the extinct mammals encountered as fossils in the various formations among and above the great Columbia Basalt series of the Pacific Northwest. A few shown as appearing in the Lake Vantage horizon of the basalts.

Geology Of The Tuxedo Mining District, R. W. Lawson, B. R. Tarrant, A. L. Gallagher

Bachelors Theses and Reports, 1928 - 1970

The Tuxedo mining district lies fifteen miles west of Butte on the south east end of Deer Lodge valley. Prospecting and mining has been carried on in this district for about 20 years. As a result many pits have been dug, several adits have been driven, and two or three shallow shafts have been sunk.

The Deposition Of Monomolecular Films., Albert Wilbur Schlechten

Bachelors Theses and Reports, 1928 - 1970

The formation of monomolecular films is possible because of the action of the heteropolar molecules of certain fatty acids, especially stearic. Under the proper conditions the acid will spread out until a monomolecular film is formed.

Determination Of Fossil Woods (Part Iv-Walnut-Hickory-Persimmon), George F. Beck

All Faculty Scholarship for the College of the Sciences

These three woods undoubtedly ranged over Western America in Tertiary and were well represented in the Ginkgo series of forest during Miocene. Fossil walnut wood is the more abundant of the three species, while hickory is not common.

Determination Of Fossil Woods (Part Iii-The Elms), George F. Beck

All Faculty Scholarship for the College of the Sciences

The elms are among the best known and most beloved trees found native to America. Like the redwood they belong to that large group of trees which in preglacial days grew generally over the northern hemisphere.

Camels Of The Columbia Plateau, George F. Beck

All Faculty Scholarship for the College of the Sciences

However foreign they may seem to us the camels are one of our oldest American stocks. Our Western plains once supported large herds of them, humped and humpless, large and small, giraffe-necked and normal-necked. For some 35 million years, from Oligocene to the Pliocene, the camels were confined to North America and it was not until recently, geologically speaking that we shared the race with the Old World.

Determination Of Fossil Woods (Part Ii-The Oaks), George F. Beck

All Faculty Scholarship for the College of the Sciences

The oaks, unlike the sacred ginkgo or temple tree, are thriving throughout the northern hemisphere today. Not only is the oak an entirely familiar and abundant element in existing landscapes, but its history goes back into the centuries and ages. Its leaves and woods are generously represented in fossil forests as far back as the early Tertiary and closely allied forms penetrate as far back as the Cretaceous.
