Surficial Geology Of Northern Griggs County, North Dakota, Laverne C. Rude
Surficial Geology Of Northern Griggs County, North Dakota, Laverne C. Rude
Theses and Dissertations
Griggs County, situated in the Western Lake section of the Central Lowland province, covers an area of 720 square miles in east-central North Dakota. The surface of the county is mantled with three, or possibly four Pleistocene drift sheets, separated by outwash deposits. These drift sheets lie unconformably on the Cretaceous Pierre Shale which is exposed in the Sheyenne River valley and the Binford Hills. Because the drift sheets have similar lithologic and physical characteristics, and are all late Wisconsin in age, they fulfill the requirements for a lithostratigraphic unit and are being considered for designation as part of the …

Geology Of The Southern Part Of Wellsville Mountain, Wasatch Range, Utah, Ronald H. Gelnett
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wellsville Mountain is 10 miles west of Logan, Utah, at the northern extremity of the Wasatch Range. Paleozoic rocks form a northeast-dipping homocline bounded in part by northwest-trending high-angle faults and cut by a series of northeast-trending high-angle faults. A major transverse fault, with a stratigraphic displacement of 4,500 feet, divides the mountain into two distinct blocks.
The rock units of the area are comparable to those of the Logan quadrangle immediately to the east. Pre-Cambrian rocks crop out in Box Elder Canyon, just east of Brigham City, and are overlain by at least 20,000 feet of northeast-dipping Paleozoic rocks …

An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach
An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach
Bachelors Theses and Reports, 1928 - 1970
Many fine-grained igneous rocks, basaltic and felsitic in character, are difficult to classify. In numerous cases, it is impossible to classify these types of rocks by quick methods of identification. It was hoped at the beginning of this study that refractive indices of glasses formed by quick artificial fusion of samples from selected suites of igneous rocks would show a close correlation in chemical composition.

Arctic Gold, Alaska, Joel Halpern
Arctic Gold, Alaska, Joel Halpern
Joel M. Halpern
To armchair travelers, especially in the United States, few places have a stronger allure than far-off Alaska. Now that the "wild and woolly" west is really alive only so far as it serves to accentuate our historical heritage, this land of the far north has become our last frontier. To the geologist, mineralogist, and, I might add, even to the layman, one of the most interesting features of the territory is its large placer gold deposits. Every American boy has heard of the Nome gold rush, and the more literarily adventurous have undoubtedly delved into the sagas of Jack London. …
