Results of Core Drilling of Uranium-Bearing Lignite Deposits in Harding and Perkins Counties, South Dakota, and Bowman County, North Dakota

Description: Purpose: The main objective of the Dakota core drilling program was to determine reserves of uraniferous lignite based on chemical uranium and spectrographic determinations from unweathered samples, particularly from those areas where surface sampling of the beds during the previous field season indicated that significant deposits of uranium-bearing lignite might be present. A secondary objective was to obtain fresh samples and to measure the radioactivity of the overlying Oligocene White River and Miocene Arikaree formations from which the uranium in lignite is believed to have been derived.

Strippable lignite Deposits, Slope and Bowman Counties, North Dakota

Description: From abstract: Slope and Bowman Counties, N. Dak., include an area of about 2,450 square miles in the southeastern part of the Fort Union coal region of North Dakota, South Dakota, and Montana. In anticipation of a future increase in the demand for the low-rank coal of this region as a fuel for electric power plants and as a raw material for various chemical synthesizing processes, Slope and Bowman Counties were investigated for deposits of lignite that could be mined by large scale strip mining methods. All the lignite beds of economic importance in this area are in the Fort Union formation, particularly in the Tongue River member. The beds are nearly horizontal, dipping about 25 to 50 feet per mile north and northeast from the Cedar Creek anticline in the southwest corner of the area.

Tectonic Map of Western North Dakota Showing the Distribution of Uranium Deposits

Description: From introduction: A tectonic map for the northern part of the Cordilleran Foreland / is being compiled to aid in establishing the geologic setting of uranium deposits within the region and to determine relationships, if any, that exist between the distribution of uranium deposits and the regional tectonic pattern (Osterwald, 1955).

Stratigraphy and Geologic History of the Montana Group and Equivalent Rocks, Montana, Wyoming, and North and South Dakota

Description: From introduction: This is a progress report on regional stratigraphic and paleontologic studies of the Upper Cretaceous Montana Group and equivalent rocks in the northern part of the western interior of the United States. It presents preliminary data on the positions of strandlines during a 14-m.y. (million year) span of the Late Cretaceous as well as our interpretations of the geologic history of this period.

Condition Survey: Minot Air Force Base, North Dakota

Description: The purpose of this report is to present the results of a condition survey performed at Minot Air Force Base (MAFB), North Dakota, during 11-15 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost action to the pavement facilities.

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

Description: From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."
