The Geology Of The Interstate Highway 244 And 44 Exchange, Kirkwood, Missouri, John Neil Thomas

Masters Theses

"During the summer of 1964, construction was completed on the intersection of Interstate Highways 244, 44 and U.S. Highway 66, one mile southwest of Kirkwood, Missouri. during the construction of the interchange, numerous artificial exposures of rocks of the middle Mississippian Meramecian Series were exposed. This provided an excellent opportunity for examining fresh exposures near the type Meramecian Series. The formations of the area were studied, and startigraphic [sic] sections were prepared from three of the more complete sections that were measured and described. The highway cuts expose complete sections of the Warsaw and Salem formations, and the lower part …

Geology, Geochemistry And Genesis Of Selected Skarn Deposits, Northern New Brunswick, Canada, Donald John Bachinski

Masters Theses

"An exhaustive geological and geochemical study is presented of magnetite-chalcopyrite skarn deposits occurring within the thermal aureole of the Nicholas Denys quartz maonzonie-granodiorite stock. The deposits are crudely lenticular and occur in metamorphosed impure limestone and siliceous, in part limy, argillite-greywacke. These are now represented by andradite-epidote-diopside-calcite skarn and cal-silicate to horn-felsic rocks respectively. Both deposits are spatially related to the Main fault of the Rocky Brook-Millstream fault system; late, generally northwest trending transverse faults are conspicuous and are deemed of importance in ore localization"--Abstract, page [ii].

Geochemical Prospecting For Copper In The Northern Part Of Yuma County, Arizona, Abdul Razak Kasim Al-Hashimi

Masters Theses

"Geochemical prospecting for copper has been carried out in two selected areas in the northern part of Yuma County, Arizona. These areas have a few old copper mines and some other zones of mineralization. The rocks of the area range in age from Precambrian to Quaternary and consist of complex gneiss, lava flows, schists, marble, sandstone, conglomerates and some intrusive dikes. A cold-extractible [sic] field method was used to study the relation between the copper content of stream sediments in washes and the geology, mineralization, and topography of the areas. A few total copper tests were also carried out. Another …

A Study Of The Piezometric Surface Of The Grand Falls Formation In The Duenweg-Oronogo Mining Belt East Of Joplin, Missouri, Renny Roger Nichols

Masters Theses

"The Joplin area of Missouri, which includes the Duenweg-Oronogo belt, was a famous zinc and lead mining district. Many mines were abandoned after World War I and filled with water. These provide a large potential supply of ground water. Expansion of industries and population in the area since World War II has caused a demand for water. In 1964, the Ground Water Branch, Water Resources Division, of the United States Geological Survey began a project to study the surface and ground water resources of the area. As part of his work on this project, the author measured the piezometric level …

Taxonomic Study Of Fossil And Recent Otoliths Of Certain Cuskeels, Gary Neal Pointer

Masters Theses

"Otoliths are calcareous structures occurring in the auditory labyrinths of teleost (bony) fishes. Three pairs of these earstones normally are found: the sagitta, in the sacculus; the asteriscus, in the lagena; and the lapillus in the utriculus. In fishes other than the Order cypriniformes (carp, catfishes, and related forms), the sagitta is the largest otolith, and it may be used in taxonomic and other studies. Fossil earstones of cuskeels (Family Ophidiiae-Brotulidae), constituting the Preophidion complex, occur in relative abundance at various levels in the Claiborne, Jackson, and Vicksburg groups of the Lower Tertiary on the Gulf Coast. The present study …

Geology Of Cienega Mining District, Northwestern Yuma County, Arizona, Elias Zambrano

Masters Theses

"The purpose of this investigation was to determine the general geology of an unusually complex area containing several small mines and located in the northwest corner of Yuma County, Arizona. This report is the first attempt to work out in detail the lithology, structure, stratigraphy, petrography, and economic geology of the area"--Introduction, Purpose and Scope, page 1.

Petrology And Mineralogy Of The "Old Workings Area," El Salvador, Chile, Bertis James Vander Schaaff

Masters Theses

"The 'Old Workings Area,' so called for its early mining by the Incas, is located 4 1/2 miles northeast of the El Salvador Porphyry copper deposit, the third largest copper producer in Chile. The area mapped in this study is shown to consist of rhyolite pebble conglomerate, two volcanic flows, andesite and rhyolite porphyry, and two intrusions. Quartz porphyry and tourmaline-bearing breccia. Petrographic study of surface and drill core rock samples confirms the field nomenclature used for the five rock types. All of the rock types are altered, but the quartz porphyry and andesite are the most intensely altered. Both …

Geology Of Pride Mine And New Standard Mine Area, Northwestern Yuma County, Arizona, Henry E. Fernandez

Masters Theses

"A thick section of presumably Precambrian gneiss with thin intercalated bands of marble and schist has been mapped. There is structural continuity within these rock types as they are mutually intercalated, conformable, have gradational relations and show equal participation in the same individual fold. The layers of schist and marble in the gneiss can be followed over long distances. These rocks have undergone intense regional metamorphism, primarily dynamic, with a possible regional compressive force generated from NW-SE giving rise to sets of folds and faults in the area. From structural, petrographic and field evidence, it is concluded that the metamorphic …

Zinc And Copper Content Of Stream Sediment In South-Central Missouri, Shih-Cheang Cheng

Masters Theses

"Thirty samples of stream sediment from the North Fork River, Bryant Creek and related tributaries in south-central Missouri have been analyzed for cold-extractable copper, cold-extractable heavy metal, total copper and total zinc.

Cold-extractable copper varies from 0 to 10 ppm and averages less than 1 ppm; cold-extractable heavy metal varies from 3 to 30 ppm and averages 12 ppm; total copper varies from 50 to 200 ppm and averages 88 ppm; total zinc varies from 20 to 300 ppm and averages 86 ppm.

The pH of the stream water appears to have no affect on the metal content of the …

A Terrain Study Of The Bloodland Quadrangle, Pulaski County, Missouri, Lawrence E. Mullins

Masters Theses

"This study is an investigation of the environmental conditions which affect cross country movement for tracked military vehicles on a major portion of the Fort Leonard Wood Military Reservation.

The terrain has been mapped from the trafficability standpoint by an investigation of the geology, topography, pedology and restrictive vegetation characteristics of the Bloodland seven and one-half minute quadrangle. The terrain analysis was accomplished by a combination of map study, laboratory investigation, photo interpretation, and direct field study of representative soil and vegetation types. The conclusions of this analysis are presented in the form of a cross country movement map"--Abstract, page …
