Foraminiferida From Outcrops Of The Niobrara Shale (Upper Cretaceous) Of North Dakota, Kent A. Madenwald

Theses and Dissertations

Microfossils were obtained from outcrop samples of the Niobrara Formation in northeastern North Dakota and from subsurface samples in southeastern North Dakota. Ninety-three species of foraminiferids, of which two are new and eight others of uncertain assignment, are described and figured. One species previously reported from the Oligocene and Niocene of Trinidad and two species from the Lower Oligocene and Niocene of Antigua, B. W. I., were collected and described which extend the range of those species down to the Upper Cretaceous. The major portion of the fauna described is correlative with previously described faunas from Nebraska, Kansas and South …

The Micropaleontology And Stratigraphy Of The Subsurface "Heath" Formation (Mississippian-Pennsylvanian) Of Western North Dakota, Harold C. Ziebarth

Theses and Dissertations

The thesis here abstracted was written under the direction of F. D. Holland, Jr., and approved by Wilson M. Laird and Walter L. Moore as members of the examining committee, of which Dr. Holland was chairman.

The “Heath” Formation, between the underlying Otter and the overlying Amsden(?) Formations in the subsurface of southwestern North Dakota, is a source of petroleum in the Scoria-Fryburg, Rocky Ridge and Dickinson oil fields. Cores, cut from the interval under study, of twenty wells in this area, were the source of fossil and lithologic samples studied. Changes in lithology in these cores compared with changes …

The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville

Theses and Dissertations

Southern Logan County, North Dakota, was glaciated at least three different times during the Pleistocene epoch. Scattered patches of highly weathered iron-cemented drift found in the area of eroded Cretaceous bedrock in southwest-era Logan County are very possibly pre-Wisconsinan in age. Two younger drift sheets of Wisconsinan age cover the remaining portion of the county. One of these drifts, the Napoleon drift, is probably early Wisconsinan, and the other, the Burnstad-Streeter drift, is likely late Wisconsinan in age.

A great diversity in types of glacial topography and individual features is found in southern Logan County. Excellent examples of end moraine, …

Glacial Geology Of South-Central Kidder County, North Dakota, Barrett J. Williams

Theses and Dissertations

South-central Kidder County is covered with deposits of drift brought by ice sheets which invaded the areas from the northeast and east. Bedrock of Cretaceous age underlies the drift mantle. The drift on the surface in Kidder County represents the Cary and Mankato substages of the Wisconsin Stage of Pleistocene series.

Three types of moraines, ground, stagnation, and end moraine, are present in the area. Five late Wisconsin and moraines are distinguished and named in this portion of Kidder County. These are, from west to east and oldest to youngest, the Long Lake loop and Sibley Buttes loop of Cary …

Stratigraphy Of The Winnipeg And Deadwood Formations In North Dakota, Clarence G. Carlson

Theses and Dissertations

The Deadwood formation includes all of the pre-Winnipeg sedimentary rocks of North Dakota which range in thickness from an erosional edge in the subsurface of northeastern North Dakota to at least 1,000 feet in northwestern North Dakota. It is composed of sandstone, shale, and carbonate of Late Cambrian to Early Crdovician age. Facies relationships are not entirely clear, but sedimentation appears to have been continuous from Late Cambrian to Early Crdovician in the Williston Basin. Conodonts from the upper part of the Deadwood formation in northwestern North Dakota are brownish-black, mostly simple cone types and suggest an Early Drdovician age …

Pleistocene Geology Of Northern Kidder County, North Dakota, James Chmelik

Theses and Dissertations

The topography of northern Kidder County is due almost entirely to glacial deposition. This are is covered with glacial drift up to a thickness of at least 269 feet which was deposited during Wisconsin ice advances. Seventy-five percent of the area has stagnation moraine which typically exhibits knob-and-kettle topography, has high local relief with no linear trends, and which was deposited after the ice became stagnant. Many kames and eskers were formed contemporaneously with stagnation moraine. The names, Lake Williams and Woodhouse Lake loops, and proposed for and moraines deposited by Cary and Mankato ice advances, respectively. The Lake Williams …

An Investigation Of The Bakken And Englewood Formations (Kinderhookian) Of North Dakota And Northwestern South Dakota, Jack Kume

Theses and Dissertations

Lower Mississippian rocks of the Williston Basin and Black Hills include the Bakken and Englewood formations of Kinderhockian age. The Englewood formation crops out in the northern Black Hills and can be traced with difficulty into the subsurface. The Bakken formation does not crop out in the area out in the area of this study. This study is based upon well sample and mechanical log information and measured surface sections.

The Englewood in the outcrops consists of a lower shale unit, a middle argillaceous and shaly limestone unit, and an upper delominte limestone unit. A type section, NW, SE; see. …

The Surficial Geology Of North-Central Kidder County, North Dakota, Wallace E. Bakken

Theses and Dissertations

Kidder County is situated in central North Dakota within the glaciated Missouri Plateau. Rocks underlying the drift range from Cretaceous (Pierre formation) through Palocene (Tongue River formation) in age. The Pierre and Fox Hills formations constitute the majority of the pre-Pleistocene surface. Ice-shove deformation, apparently during Cary time, tilted blocks of Fox Hills in the Sibley Buttes into northeastward-dipping positions.

Cary and Mankato subages of Wisconsin age are represented at the surface. Ages are difficult to assign to drift sheets on the basis of lithology or degree of weathering of included tills; but by correlation from South Dakota and crosscutting …

The Basement Of North Dakota, Spurgeon C. Crosby Ii.

Theses and Dissertations

The purpose of this report is to study the basement rocks of North Dakota. The basement rocks of North Dakota may be divided into two categories. The eastern division comprises deeply weathered material and extends from the Red River westward for approximately thirty miles. The western division essentially comprising adamellite (more than 1/3 but less than 2/3 alkali feldspar and more than 10 percent quartz), extends from a north-south line thirty miles west of the Red River to the Montana border.

Foraminifera From Outcrops Of The Pierre Shale (Upper Cretaceous) Of North Dakota, Everett E. Wilson

Theses and Dissertations

In North Dakota the Pierre shale was deposited in all portions of the State except the southeastern corner, where it was either never deposited or removed by pre-Pleistocene erosion. In the western part of North Dakota the Pierre is overlain by later Cretaceous and Tertiary sediments, but to the east of the Missouri River, where it forms the bedrock, it is mantled by glacial drift. However, numerous exposures of the Pierre are present, generally in road cuts and river valleys of the southwestern and northeastern corners of the State. More scattered outcrops occur along Beaver Creek and the Missouri River …

The Stratigraphy And Geologic History Of The Cannonball Formation (Paleocene), Gary O. Hall

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 …

The Geology Of The Grassy Butte Area, Mckenzie County, North Dakota, Elmer G. Meldahl

Stream Piracy And Glacial Diversion Of Little Missouri River, North Dakota, Emmett R. Schmitz

Theses and Dissertations

Bedrock river terraces, as much as 275 to 500 feet above the present Little Missouri, are remnants of a former floodplain. The presence of these former shallow valley floor (Little Missouri Terrace No. 4) along the pre-glacial channel and east and north of the Killdeer Mountains suggests several pre-glacial rivers.

Peripheral precipitation in advance of the Kansan-Illinoian glacier, head-ward erosion with consequent new gradient breached the divide between the pre-glacial Little Missouri River and the “Medicine Stone” River, (herein named, after a local landmark), which flowed eastward into pre-glacial Missouri River.

The history of that portion of the Little Missouri …

A Geomagnetic Survey Of Parts Of Pierce, Benson, Sheridan And Wells Counties, Harald C. Haraldson

Theses and Dissertations

A magnetometer survey in respect to oil exploration is a regional reconnaissance tool and, therefore, it is customary to check an interesting magnetic anomaly with a seismograph or gravimeter. An exception to this is found in micro magnetic surveys which, because of their detailed nature 28 nature, may serve as a cheek on the other types of geophysical surveying.

The two large magnetic highs may be more areas in the basement rocks, and they may indicate structure. However, the large eastward-trending magnetic high area on the west side of the map area is quite possibly due to a regional increase …

The Sorption Of Fluoride Ion With Special Reference To Fluoride Removal From Potable Waters, Phillip W. West

Theses and Dissertations

The recent discovery that even very small concentrations of fluorides in drinking waters are sufficient to cause the serious dental dystrophy commonly known as mottled enamel, has around widespread interest and concern. Federal and State surveys have been conducted to determine the geographical distribution of the malady, and the fluoride contents of water supplies.

County dental surveys, conducted by the United States Public Health Department with the cooperation of local dentists, have located the regions throughout the country where mottled enamel is endemic and among these localities is an area in southeastern North Dakota and adjacent territory in South Dakota …

A Study Of The Colloid Obtained From Weathered Lignite, Cecil O. Lohn

Theses and Dissertations

When Lignite is exposed to the action of weather it undergoes various changes, probably due to oxidation. Surface beds of lignite are often rejected by the miners as inferior coal, due to the weathered condition. But when this weathered lignite is treated with sodium hydroxide, and the resulting solution allowed to evaporate to dryness, there is left a hard, shiny substance very similar in appearance to hard coal. This dried product has been exploited under the name of Dakolite. When dispersed in water this product makes a very good wood stain.

Tests made on Dakolite show that it has colloidal …
