Permeability Study Of Algal Reef Beds Within The Bonneterre Formation, National Mine, St. Francois, Missouri, Bobbie L. Perry

Masters Theses

"The Missouri "Lead Belt" comprises approximately 50 square miles, centering around the town of Flat River, in St. Francois County. Missouri. This district has been producing lead for more than 200 years, the total production being at least 8,000,000 tons of lead, valued at more than $1,000,000,000. For many years, the annual production of the district has been at least one-fourth of the total production in the United States.

An excellent description of the geology of this area was published recently by Ohle and Brown in 1954.

The ore consists principally of galena which is disseminated within the Bonneterre formation …

Industrial Wastes: Bio-Assays For Control Of Industrial Effluents, Croswell Henderson, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Waste effluents from many industries are toxic to fish and other aquatic life. The control or treatment of these wastes for safe release into receiving waters presents a problem of consider able magnitude.

Much effort has been expended by some industries to solve this problem, primarily through chemical analysis for possible toxic components and then generally by a search of the literature to find out how toxic a particular component may be. Unfortunately, this approach has not been successful, nor can it be expected to be productive of satisfactory answers.

A Study Of The Charles-Mission Canyon Contact, David H. Dahlem

Bachelors Theses and Reports, 1928 - 1970

This study is an attempt to define criteria for picking the Charles-Mission Canyon contact from well-cuttings logs, electric logs and radio-active logs; and all findings are discussed, whether positive or negative. Correlation by electric log was successful from the Cut Bank area to the Cedar Creek anticline but sample logs from the same wells do not agree. The conclusions reached is the point to the unreliability of the sample logs based on well-outtings data.

Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

The accurate geologic dating of Pleistocene vertebrate localities which occur outside the glaciated regions has always been difficult. Several new fossil localities in Nebraska now provide data for a better understanding of the paleoecology and faunal evidence of the medial Pleistocene of the Great Plains region.

A fossil quarry, containing the remains of both vertebrates and invertebrates, has been discovered in south-central Nebraska (11/2 miles south and west of Angus in Nuckolls County). The fossils are preserved in Sappa silts in a lime concentration zone (C horizon) of a Yarmouth paleosol. The calcium carbonate appears to have been responsible for …

Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are …

Pre-Cambrian Geology Of Washington County Area, Missouri, Gordon Blair French

Masters Theses

"The Problem.

Washington County, Missouri contains a limited number of outcrops of pre-Cambrian igneous rocks, the majority of which are in the extreme southern part of the county. The known association of lead ore with buried or partially buried pre-Cambrian igneous knobs and ridges in this part of Missouri has led the St. Joseph Lead Company to prospect in areas known to contain these features. In its exploration program, the St. Joseph Lead Company has drilled a number of prospect holes which have encountered other occurrences of pre-Cambrian igneous rocks within the limits of Washington County. This drilling, correlated with …

The objective of this thesis is to present a program for the collection of basic hydrologic data for the state of New Mexico. It is an expansion of the existing program which currently becomes more inadequate with the progressively extensive use of the water resources of the state. The need for hydrologic data for planning and operation of water use and control structures far exceeds that obtained by the existing program.

Types of data reported upon are climatological, stream flow, ground water, quality of water, suspended sediment, snow cover and reservoir, valley and channel sedimentation. For the purposes presented herein …

Geology Of A Portion Of The Hand Mine, Argenta Mining District, Beaverhead County, Montana, John Thomas Richards

Bachelors Theses and Reports, 1928 - 1970

The Hand Mine is located in the Argenta Mining District near the town of Argenta. The area surrounding the Hand Mine is characterized by intense thrusting, folding, and igneous activity. The area mapped by the author is in the southeast portion of the mine and differs from the rest of the mine in that no commercial ore has been found. The writer concludes that the steep faulting and flatlying bodies are of two different ages, and that intense oxidation has altered the ore minerals to plumbojarosite.

Oxidized Copper Mineralization Along The Continental Fault Near Butte, Montana, Theodore H. Eyde

Bachelors Theses and Reports, 1928 - 1970

Located in the fault zone of the Continental fault near the western edge of Boulder batholith of southwestern Montana the oxidized copper deposits are developed by three open pit mines, one of which is a presently in operation. Copper has been deposited by descending cold solutions which have leached copper from the surrounding quartz monzonite and deposited within the crushed fault zone. Local high grade 'bunches' of ore occur along narrow limonite veins, remnants of primary sulfide veins which have been enriched by the descending cold solutions.

Industrial Wastes, Charles E. Renn

United States Environmental Protection Agency: Publications

This paper presents a summary of experiences with a variety of cyanogenic wastes. The work has attempted to evaluate the interaction of waste bearing waters and the environment in terms of waste disposal design requirements. In this, the approach is somewhat more critical than that commonly taken by fisheries biologists, conservationists, and others who have been concerned with the "preventive" aspects of waste disposal.

The first phases of the work were designed to discover the tolerable limits of certain waste components to fresh water fish. This was undertaken in 1950; in the interval the composition of the wastes has been …
