Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

Study Of The Copper-Uranium Deposits At Vilcabamba, Department Of Cuzco, Peru, Oscar Aguilar

Masters Theses

"Uranium has been known in the Vilcabamba district of Cuzco, Peru since 1954. Copper ores of high silver content were worked by the Spaniards during the seventeenth and the early eighteenth centuries, At the beginning of the twentieth century these ores were worked intermittently; during the last fifty years no mining operation has been going on.

The oldest rocks in the thesis area consist of Ordovician phyllites. The presence of Devonian in the area is questionable, but has been recognized 5 km. away from the thesis area. A conglomerate of limited lateral extent of Mississippian age overlies the Devonian (?) …

Investigation And Development Of Ground Water Of Chalone Creek, (Pinnacles National Monument, California), Donald Lee Brown

Masters Theses

"The Pinnacles National Monument is located in San Benito and Monterey Counties about 130 highway miles south of San Francisco, California. Because of unusual patterns in volcanic rocks, the Monument was set aside as a recreation area on January 16, 1908, by President Theodore Roosevelt. It encompasses an area of approximately 12,818 acres.

Water quality and supply problems were experienced at the Monument in the few years prior to 1961. In 1961, a collection trench system was installed to alleviate the water supply condition. A horizontal trench system, 215 feet long and four feet below the dry season water table, …

Geology And Ground-Water Resources Of Northern Lea County, New Mexico, Sidney R. Ash

Earth and Planetary Sciences ETDs

The economy of northern Lea County is dependent upon groundwater; the only other source of water is the runoff from precipitation that is caught and retained in the man-made or natural reservoirs, where is it used for water stock. Irrigation utilizes most of the groundwater pumped; much smaller amounts are used for stock watering and industrial, public, rural and domestic supplies. In 1958, about 107,000 acre-feet of groundwater was pumped for irrigation and 19,000 acre-feet was pumped for all other uses. On the basis of present production of potable water, the economically usable supply will be depleted in certain areas …

Petrology Of The Precambrian Rocks Of Part Of The Monte Largo Area, Nm, Paul Wayne Lambert

Earth and Planetary Sciences ETDs

Approximately 7 to 8 square miles of Precambrian rocks are exposed in the vicinity of the Monte Largo Hills in north-central New Mexico. The Precambrian rocks are bounded mainly by Pennsylvanian sedimentary rocks in both fault and noncomformable contact.

The area is made up largely of quartz-feldspar gneiss, hornblende gneiss, and quartzite. Quartz-feldspar gneiss is the most abundant rock type. Mica schist and sillimanite hornfels occur in minor amounts. Other Precambrian rocks include medium-grained granite, splite and pegmatite dikes, and quartz veins. A minor amount of migmatite is present as a result of the intimate association of quartz-feldspar gneiss and …

A Petrographic And Environmental Study Of The Upper Cretaceous Greenhorn Limestone, New Mexico, John W. Emerson

Earth and Planetary Sciences ETDs

The Upper Cretaceous Greenhorn Limestone is composed of intercalated agrillaceous limestone and calcareous shale beds which crop out over much of the Western Interior. The Greenhorn was deposited in late Cenomanian and early Turonian time in a westward transgressing sea. In New Mexico the age is early Turonian. The edge of deposition extends as far south as Capitan and Carthage, northward through western Bernalillio County, and northwest through Toadlena.

Geology Of The Queen Lake Domes Near Malaga, Eddy County, New Mexico, George R. Reddy

Earth and Planetary Sciences ETDs

There are many domes in the vicinity of Queen Lake near the Pecos River in southern Eddy County. The rocks involved in the doming range in age from Permian to Recent. Their relationships indicate that there were two periods of doming, the first during early Pleistocene time and the second after the formation of Recent caliche.

Salt beds are present in the Salado and Castile formations beneath the area in which the domes are distributed. At Queen Lake the salt is within 300 feet of the surface. Farther east, the salt-bearing rocks are buried beneath Triassic and Cenozoic deposits. These …

Lithogenesis Of Atoll Sediments, Uliga Island, Majuro Atoll, Marshall Islands, Phyllis B. Helms

Earth and Planetary Sciences ETDs

Sixteen thin sections and 53 samples of rock and sand were examined under petrographic and binocular microscopes to determine composition, kinds of cement, degrees of cementation, and the sequence of lithogenesis of the consolidated materials. Studies were made of the loose sediments to relate the characteristics of the sedimentary grains to environmental energy of today, and then collate these data with the lithified sediments.

Sedimentary Petrogenesis Of The Yeso-Glorieta San Andres Transition, Joyita Hills, Socorro County, New Mexico, James R. Huber

Earth and Planetary Sciences ETDs

The transitional character of the middle Permian (Leonardian and Guadalupian) Yeso Formation, Glorieta sandstone, and San Andres formation in central New Mexico has been recognized in several reports (Needham and Bates, 1943; Wilpolt, et. al., 1946; Wilpolt and Wanek, 1951; and Boyd, 1958). Interpretation of the depositional history and environment of this sequence has been restricted to generalizations based on field observation.

A detailed petrographic study of the Yeso-Glorieta-San Andres transition at a single locality was undertaken in an attempt to gain better understanding of this stratigraphic interval.

Geology Of The Nutria Monocline, Mckinley County, New Mexico, R. John Edmonds

Earth and Planetary Sciences ETDs

The Nutria monocline forms the northwestern boundary of the Zuni uplift in McKinley County, New Mexico. The sedimentary rocks that are exposed along the monocline range in age from Permian to Cretaceous and rest on Granite of probable Precambrian age. The Jurassic Todilto limestone, which is present north of the mapped area, pinches out in a southerly direction. South of this pinch-out the massive sandstone of the Entrada formation joins the main body of the Zuni sandstone. Only the even bedded, silty sandstone that has previously been considered to be the middle member of the Entrada is regarded as Entrada …

The Effect Of Moisture And Temperature On Transformation Of Applied Ammonium Sulfate In Several Western Soils, Lloyd Richard Hossner

Phosphorus Status Of Genola Soils In Utah, Warren E. Bendixen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With increasing pressure on economical production of crops, more fertilizers are being applied to the soil each year to increase crop yields. Economical production of crops with applications of fertilizer requires an evaluation of the essential elements of the various crops so applications of fertilizer will not exceed the law of diminishing returns.

Because varying soil, moisture, and climatic conditions influence the response to added fertilizers, some workers (18, 26, 38) have contended that the only reliable way of determining the fertilization needs of a crop is to conduct a trial on the particular farm. The length of time involved …
