Geology Of The Northern Part Of The Fra Cristobal Range, Sierra And Socorro Counties, New Mexico, John T. Mccleary

Earth and Planetary Sciences ETDs

The northern part of the Fra Cristobal Range contains rocks of Precambrian, Cambrian, Pennsylvanian, Permian, Cretaceous, Tertiary and Quaternary age. One of the northernmost exposures in New Mexico of the Cambrian Bliss formation occurs in the central part of the range. Here the bliss formation wedges out due to widespread pre-Pennsylvanian erosion which removed all the other lower Paleozoic rocks.

The Pennsylvanian Magdalena group, which is predominately limestone, rests uncomformably on Precambrian rock and the Bliss Formation. It forms the greatest part of the sedimentary sequence and is divided into three formations; the Red House, Nakaye, and Bar B formations …

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 …

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 …

Comparative Petrographic, Petrochemical And Spectrographic Analyses Of The Precambrian Granitic Rocks Of Southeastern Missouri, Eva B. Kisvarsanyi

Masters Theses

"Petrographic, petrochemical and spectrographic studies were completed on selected Precambrian granitic rock samples from Southeastern Missouri. This investigation contributes to a more detailed knowledge of the Precambrian granitic rocks of this part of the state.

Petrographic analysis of forty-four thin sections of granitic rocks from the St. Francois Mountains area revealed six different granite types. These have been named the Fredericktown, Knoblick, Doerun, Graniteville, Klondike and Silvermine granites. These rocks form a large part of a composite batholith. More than one period of granitic intrusion is represented, but differentiation also contributed to the formation of this diversity of the rocks. …

Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.

Masters Theses

"Lenticular bodies of massive limestone, flanked by thin crinoidal beds, crop out in southwestern Missouri and northwestern Arkansas. They are within the St. Joe limestone of the Lower Mississippian.

Strata underlying these bodies typically are down-warped, those on the flanks lapping against, finally passing completely over the limestone core. Dips away from the “reef” are commonly around 5 degrees, but reach as much as 30 degrees. Conglomeratic detritus, originating from the core, occurs in flanking beds at their contact with it.

Thin sections of these masses show no more than 15 per cent of the limestone to consist of fossil …

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 …

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 …

Occurrence Of Mineralized Ground Water In Southern St. Louis And Jefferson Counties, Missouri, Willard Glennon Owens

Masters Theses

"Mineralized ground water occurs at some localities in southeastern St. Louis and northern Jefferson counties, Missouri. This water is usually undesirable and is detrimental to development of ground water resources.

Water well records in the offices of the Missouri Geological Survey and Water Resources provided data for a study of structure, lithology and occurrence of ground water. Water well drillers and property owners were interviewed to obtain additional information concerning drilling problems and quality of water.

Geologic cross-sections, subsurface contour maps and isochlorinity maps aided the study of lithology, structure and areal distribution of mineralized ground water. Relationship is suggested …

Early History Of Malad Valley, Glade F. Howell

Theses and Dissertations

The Malad Valley is geographically located in a unique position in the Pacific Northwest. The Bear River and its main affluent, the Malad River, are the only rivers in the Pacific Northwest that drain into the Great Basin, whereas the other streams and rivers of the states of Washington, Idaho, and Oregon empty eventually into the Pacific Ocean. It is also characterized for being the northern end of prehistoric Lake Bonneville, and eventually it was through this valley that an outlet opened to drain the lake. The soil deposits from this lake left a fertile valley, capable of producing most …

Comprehensive Survey Of Sedimentation In Lake Mead, 1948-49, W. O. Smith, C. P. Vetter, G. B. Cummings, U.S. Bureau Of Reclamation

Publications (WR)

Reservoirs are becoming an increasingly prominent feature of the American landscape. Built for flood mitigation and to change a fluctuating river into a dependable source of water for irrigation, power, and other purposes, they are predestined, like natural lakes, to be destroyed sometime following their creation. Sedimentation sooner or later robs most lakes and reservoirs of their capacity to store water. The significance of sedimentation in the life of Lake Mead, the largest artificial reservoir in the world, was realized when the plan for the reservoir was conceived, and an aerial survey of the floor was made in 1935 before …

Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost

Theses and Dissertations

Homesteading in San Juan County, Utah is for the most part, located on Sage Plain at elevations between 6,000 to 7,200 feet. Sage Plain is an undulating surface deeply dissected with canyons. The soil is relatively shallow and the predominant vegetation is pinyon, juniper, sage brush and blue-stem grass.

The 52 year mean precipitation is 15.47 inches. Since the beginning of weather records there has been a noticeable decrease in the annual precipitation. There is generally sufficient moisture to mature winter wheat. Pinto beans are also grown in the more favorable locations.

Principle factors that have influenced homesteading and land …

Lithogenesis Of The Pennsylvanian Madera Formation Of Palomas Peak, Sandia Mountains, New Mexico., Ronald D. Perkins

Earth and Planetary Sciences ETDs

The Pennsylvanian Madera formation of Palomas Peak in the Sandia Mountains of central New Mexico is a sequence of marine limestone and minor sandstone that ranges in age from Desmoinesian to Virgilian. The limestone is predominantly clastic or bioclastic and the sandstone is arkosic. Lithologic and paleontologic evidence suggests an epineritic to infraneritic environment on a gently subsiding shelf during deposition of the Madera Sediments.

Rhythmic deposition at Palomas Peak is evidenced by alternating clastic and bioclastic limestones which may have resulted from: (1) eustatic changes in sea level, (2) tectonic fluctuations in the downwarping of the shelf, or (3) …
