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, …

K₂O/Na₂O Content As A Possible Index To The Chronological Sequence Of Some Precambrian Igneous Rocks Of Missouri, Erwin Joseph Mantei

Masters Theses

"Flame photometric analyses for K₂O and Na₂O were run on 31 samples of the Precambrian igneous rocks of Missouri. Samples were collected from the field, physically prepared and dissolved by a standard method and a modified standard method of rapid silicate analyses. The K₂O, Na₂O values obtained are averages between two methods of analyses. The modified method reduces by 80% the time required to chemically digest a rock sample. The results for both methods are not significantly different. Curtin and Company Advanced Flame Photometer was used.

Results have been plotted on graphs and a chronological sequence for the named Precambrian …

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

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

The Influence Of Temperature On The Impedance To Water Flow Through Plants, Royal Duane Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This era has been termed the atomic or space age. The greatest concern of most people seems to be centered around survival from the destruction and suffering that might be caused by atomic and nuclear weapons. However, along with this, the world is confronted with perhaps a greater disaster--a potential calamity seldom realized by most people, yet a problem which grows more serious in the world each year--a tragedy which would probably be worse than destruction from nuclear weapons. This encroaching catastrophe is starvation.

Even today the majority of the people in the world do not have enough food. Each …
