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 …

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 …

Shock-Tube Determination Of Dissociation Rates Of Oxygen, John P. Rink

Physics & Astronomy ETDs

This study has a two-fold purpose--to demonstrate the feasibility of using x-ray densitometry of shock waves to determine chemical reaction rates and to obtain an accurate, independent measurement of the dissociation rate of oxygen.

The rate of dissociation of oxygen in Xe-O₂ mixtures was measured over a temperature range of 3000°K to 6000°K. An x-ray densitometer was used to measure the density during the dissociation process behind a shock wave. It was possible to match the experimental data with theoretical density profiles over a wide range of compositions and initial conditions.

The agreement between results reported here and previous …

Phase Equilibria In Fused Salt Systems: Binary Systems Of Plutonium(Iii) Chloride With The Chlorides Of Magnesium, Calcium Strontium, And Barium, Karl W. R. Johnson

Chemistry and Chemical Biology ETDs

Fused salt systems containing oxides have received the most attention to date, because of their occurrence in minerals and ores and their application to ceramics. The next most widely studied of group of compounds are the metal halides, particularly the metal chlorides. Despite the fact that many of the metal chlorides are hygroscopic, the salts lend themselves to experimentation because a large majority undergo stable solid-liquid transformations below 1000 degrees C, are generally ionic, and are relatively non-corrosive.

Experimental Studies Of The Visible Absorption Spectrum Of Titanium (Iii) Acetylacetonate In Solutions And Rigid Glasses, Arthur L. Langhorst Jr.

Chemistry and Chemical Biology ETDs

Titanium (III) acetylacetonate was synthesized and the visible absorption spectrum was measured. A prominent absorption band, ^ymax at approximately 6000 was found with molar absorption coefficient of ~1000. The spectrum was investigated at temperatures ranging from 25 degrees C to 77 degrees K. At 7 7 degrees K the band was resolved into five well defined peaks at 4750, 5100, 5520, 5950 and 6460. An apparatus for obtaining spectrophotometric measurements of solution and rigid glasses was designed and fabricated.

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.

The Synthesis Of Potential Antitumor Compounds, Duane L. Aldous

Chemistry and Chemical Biology ETDs

The antitumor activity found in such ring systems as the purine, pyrazolo [3,4-d] pyrimidine, and the 8-azapurine prompted the preparation of the imidazo [4,5-d] pyridazine ring system. Castle and Seese were one of the first to study this ring system. 4-Aminoimidazo[4,5-d]pyridazine possessed some anitumor activity. This antitumor activity suggested the preparation of the 4,7-disubstituted-aminoimidazo{4,5-d]pyridazines reported here. The antileukemic activity reported for 6-purinethiol led to the synthesis of several 4- and/or 7-mono-and disubstitutedthioimidazo[4,5-d]pyridazines.

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.

Spectroscopic Studies Of The Luminescences Of Rare Earth Chelates, Ruth Elaine Whan

Chemistry and Chemical Biology ETDs

A variety of lanthanide chelates were prepared for preliminary luminescence studies under excitation by ultraviolet light. From these, chelates of benzoylacetone, dibenzoylmethane, tribenzoylmethane, and 8-hydroxyquinoline were selected for more extensive investigation. Energies of the lowest excited singlet and triplet states of the chelates were determined. Average values of 24,500 cm^-1 and 20,500 cm^-1 respectively were obtained for the dibenzoylmethides and 24,400 cm^-1 and 21,450 cm^-1 for the benzoylacetonates. Only small variations of a few hundred wavenumbers in the positions of the excited states were found as the chelated ion was varied. This investigation in conjunction with …

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 …

Isomerism In Bromine Nuclei, Albert Goodman

Physics & Astronomy ETDs

If the phenomenon of isomerism occurred in bromine nuclei, it would be of great help in elaborating the level schemes of these isotopes. The occurrence of isomerism in the odd isotopes of arsenic and rubidium, the nearest odd-Z neighbors to bromine, suggested similar behavior in bromine odd-Z isotopes. In this investigation, the pulsed-beam method was used to search for isomers. The procedure consisted of pulsing the beam of a Van de Graaff accelerator and counting any resulting activities during the time between beam pulses. After preliminary surveys during which natural bromine was bombarded with neutrons and natural selenium was bombarded …
