Late Pleistocene And Holocene Geology Of The Moe Site, New Town, North Dakota, Richard W. Kornbrath

Theses and Dissertations

Eight stratigraphic units of Late Cenoioic age are present around the Moe Archeological Site near New Town, North Dakota. Unit Zero is a layer of glacial sediment consisting of grayish brown pebbly clay loam. Unit One consists of fluvial and beach sand and gravel. Unit Two consists of light yellowish brown, offshore lake silt that was deposited into a glacial lake in Late Wisconsinan time. Unit Three is a layer of glacial sediment consisting of grayish brown pebbly clay loam (Late Wisconsinan). Unit Four consists of fluvial sand and gravel (Late Wisconsinan}. Unit Five is a layer of slough sediment …

Pleistocene Geology Of The Grand Forks-Bemidji Area, Northwestern Minnesota, Kenneth L. Harris

Theses and Dissertations

This is a report of a reconnaissance study of the Quaternary geology of an area in northwestern Minnesota. Surface geology was studied in an area extending from Grand Forks, North Dakota, in the northwest to Bemidji, Minnesota, in the southeast, an area of 10 723 square kilometres (4140 square miles). Near-surface stratigraphy was studied in the area of surface study and an adjacent area of equal size to the south.

Surface materials mapped range in age from Pleistocene to Holocene and include glacial, glaciofluvial, lacustrine, bog, eolian, and alluvial sediments.

Sixteen power-auger test holes, two measured sections along the Red …

Petrology And Geochemistry Of The Killdeer Carbonates, John J. Delimata

Theses and Dissertations

The strata of the proposed Killdeer Formation (Stone, W. J., 1972) in the Killdeer Mountains of Dunn County, North Dakota is composed of a sequence of tuffaceous, calcareous, dolomitized and silicified flat lying sedimentary rocks of Tertiary age. It is the purpose of this report to describe and integrate the petrology and geochemistry of these sediments.

Fieldwork was conducted during the summer of 1972. Forty-three stratigraphic sections were measured and representative samples of each were collected for further analysis. Seven section were selected as representative of the area, and samples from these were studied in thin section with the petrographic …

Glacial Stratigraphy Of Northeastern North Dakota, Howard Hobbs

Theses and Dissertations

Seven lithostratigraphic units (formations} composed dominantly of glacial sediment have been recognized in northeastern North Dakota. Three formations, the Falconer Formation (Harris and others, 1974}, the Dahlen, and Gardar Formations (Salomon, 1975). Have been previously recognized. Four formations, the Hansboro, Vang, Tiber and Cando Formations are newly recognized. Uncorrelated units of glacial sediment are described but not named. The formations are differentiated and correlated primarily by the proportion of crystalline (igneous and metamorphic rock fragments), carbonate, and shale grains in the coarse sand fraction (1 to 2 mm) of the glacial sediment. The proportion of shale grains was. Found to …
