Paragenesis, Fluid Origin, And Thermal History Of A Low-Sulfidation Epithermal Gold-Silver System, Joel William Rotert

UNLV Retrospective Theses & Dissertations

Samples of banded veins, microcrystalline quartz veins, and hydrothermal breccias +/- Au in the southern Castle Mountains, California were collected from four different zones within and up to 5 km outside the mine area in order to construct a paragenesis, interpret fluid origin, describe the thermal history, and examine fluid inclusion gas compositions as an exploration tool for low-sulfidation deposits. Two-thirds of the gold from the Lesley Ann deposit is associated with pyrite, found in zones of intense silicification, and precipitated due to sulfidation of rhyolitic host rock during the earliest stages of hydrothermal activity. The remaining gold occurs freely …

The Dynamics Of Faith-Based Organizations And Their Effects On Educational Standardization, Patricia Gail Haase

UNLV Retrospective Theses & Dissertations

Remnants of Christian tradition exist in American culture although we live in a pluralistic society. Faith-based schools seek to restore elements of the Christian tradition, believing those values essential for their children. Some in the greater community look to such schools for elements and practices to translate and apply into the greater systems; Private faith-based education is considered overall successful, but there are problems that warrant discussion. Most of the dynamics are typical of all organizations, but perhaps not expected because of the moral representation. Others dynamics are unique or exaggerated in faith-based organizations; Non-profit organizations, including faith-based, exist to …

Validity Of The Independent-Particle Approximation In X-Ray Photoemission: The Exception, Not The Rule, D. Hansen, Oliver Hemmers, H. Wang, Dennis W. Lindle, P. Focke, I. A. Sellin, Clemens Heske, H. S. Chakraborty, P. C. Deshmukh, S. T. Manson

Environmental Studies Faculty Publications

A combined experimental and theoretical study of argon valence photoionization illustrates the discovery of the broad lack of validity of the independent-particle approximation (IPA) for x-ray photoemission. In addition to previously known breakdowns of the IPA, which are limited to high photon energies and regions very near threshold, the observed breakdown in photoionization at intermediate energies demonstrates generally that the IPA is valid only in very restricted domains. These restrictions are expected to be relevant throughout the periodic table, with consequences for a wide variety of applications.

Evolutionary Patterns Of Morphometrics, Allozymes And Mitochondrial Dna In Thrashers (Genus Toxostoma), Robert M. Zink, Donna L. Dittmann, John Klicka, Rachelle C. Blackwell-Rago

Ornithology Program (HRC)

We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control region) among all species of Toxostoma. The phenetic pattern of variation in skeletal morphometrics generally matched traditional taxonomic groupings (based on plumage patterns) with the exceptions of T. redivivum, which because of its large size clusters outside of its proper evolutionary group (lecontei), and T. occelatum, which did not cluster with T. curvirostre. Skull characters contributed highly to species discrimination, suggesting …
