The Mineralogy And Paragenesis Of The Lone Star Deposit, Santa Fe County, New Mexico, Lawrence K. Lustig
The Mineralogy And Paragenesis Of The Lone Star Deposit, Santa Fe County, New Mexico, Lawrence K. Lustig
Earth and Planetary Sciences ETDs
The Lone Star deposit is located in La Bajada Canyon in western Santa Fe County, New Mexico. The exposed sedimentary rocks of the area range in age from the Cretaceous to recent. Four unconformities are present which are the result of erosional levels established during the Tertiary. The host rock of the deposit is the Cieneguilla liburgite formation. The Cieneguilla consists mainly of thin embedded limburgite flows and conglomerate of Miocene age. The Lone Star deposit lies in this conglomerate at a depth of approximately 150 feet from the top of the Cieneguilla.
Industrial Wastes: Bio-Assays For Control Of Industrial Effluents, Croswell Henderson, Clarence M. Tarzwell
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
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.

The Geology Of The Tecolote Hills Area, Lincoln County, New Mexico, Donald E. Rawson
Earth and Planetary Sciences ETDs
The Tecolote Hills in the north-central Lincoln County, New Mexico, consist of Permian, Triassic, and Cretaceous sedimentary strata intruded by early Tertiary (?) sills, dikes, and laccoliths. A partial section of the Permian Yeso formation, measured thickness 380 feet, is exposed and is overlain conformably by the Glorieta sandstone member of Permian San Andres formation. This sandstone thins, at least locally, to the south and intertongues with San Andres limestone. The maximum thickness of the Glorieta sandstone is about 215 feet. It is overlain by a 300-foot thickness of San Andres rocks, further divisible into a lower limestone member and …

This thesis is a summation of lithologic analyses of three stratigraphic sections: the Danvers 1-X Harris-Federal test, the Honaker Trail locality, and the Raplee locality in San Juan Canyon, San Juan County, Utah (FIg. 1) In these localities, the Paradox Formation as defined by Wengerd and Strickland (1954, p.2169) has been studied, inasmuch as the formation is known to contain limestone bioherms ("reefs") (Wengerd, 1951) in conjunction with biostromal strata.
Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen
Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Throughout the years lime-induced chlorosis has contributed to untold economic losses. Although this disease has challenged the technical ingenuity of outstanding plant and soil scientists, the exact cause has never been determined; consequently, no preventative measures or permanent cures can, as yet, be recommended. This physiological malady, unchecked, continues its rampage in regions where the disease is prevalent.
The problem is of wide significance because calcareous soils are distributed throughout the world. It is of primary concern to us because the majority of the land of western United States is of this type. An estimated 500,000 acres of crops growing …

The Worm Creek Quartzite Member Of The St. Charles Formation, Utah-Idaho, Anthon V. Haynie Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This report presents the results of a stratigraphic study of the Worm Creek quartzite, the basal member of the St. Charles formation of Upper Cambrian age. The member is present in the Bear River Range, the Malad Range, and the Promontory Range of Northern Utah and southeastern Idaho. The Worm Creek quartzite was differentiated as the basal unit of the St. Charles formation by Richardson (1913) and named for its occurrence in Worm Creek Canyon in the Bear River Range, Bear Lake County, Idaho.
A stratigraphic investigation of the Worm Creek quartzite, including thickness and lithologic changes, was made. Through …

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

A Geological Study Of The Irvine Ranch Area, Johnson And Campbell Counties, Wyoming, Gale E. Butterfield
Masters Theses
"The discovery of uranium in the Powder River Basin, Wyoming, by the U. S. Geological Survey in 1952 has lead to an extensive exploration program throughout the region by both private and governmental agencies. This report is a geological study of an area in the southwestern part of the basin.
Geological and radiometric mapping carried out as a part of this report indicated several areas of uranium occurrence. Some of these occurrences warrant tests by drilling.
Mineralogical and petrographic study has shown the principal uranium minerals to be carnotite and metatyuyamunite. The mineralization occurs in arkosic sandstones. Assays of the …
Gastropoda From The Pierre Shale (Upper Cretaceous) Of Emmons County, South-Central North Dakota, Alan M. Cvancara
Gastropoda From The Pierre Shale (Upper Cretaceous) Of Emmons County, South-Central North Dakota, Alan M. Cvancara
Theses and Dissertations
Fossil gastropods were studied from the upper part of the Pierre shale (Upper Cretaceous) in Emmons County, south-central North Dakota. This primary purpose of this study was to figure all gastropods found and bring the nomenclature of up to date. Secondly, an attempt was made to determine whether these fossil gastropods could be used in defining the contact between the Pierre shale and overlying Fox Hills sandstone.
Little paleontological work has been done on Pierre gastropods in North Dakota. Identification previously made seem to have been done somewhat hurriedly from Meek (1876) with little regard to modernizing the nomenclature.
These …

Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik
Department of Agronomy and Horticulture: Faculty Publications
Soil structure is important in the attainment of adequate aeration for the aerobic microorganisms whose activities maintain such higher plant nutrients as sulfur, phosphorus, and nitrogen in a highly oxidized and thus readily available state. Good soil structure is also necessary for soil and water conservation, Under Nebraska conditions microorganisms and their decomposition products constitute a major source of soil-aggregating agents. The decomposition of crop residues and plant roots is important in the nutrition of these aggregating microorganisms. Other microorganisms, however, also utilize crop residues and plant roots, and they may decompose the aggregating agents as well, so that the …
