Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.

This report consolidates and synthesizes information on Quaternary faulting, folding, and volcanism in Utah and characterizes recent tectonic activity throughout the state. The primary purpose is to provide a comprehensive reference on fault-specific seismic sources and surface rupture to facilitate the evaluation of earthquake hazards in Utah. Two 1:500,000-scale maps show Quaternary tectonic features categorized according to probable ages of most recent surface deformation and ages of volcanic rocks. Two appendix tables summarize significant data on the activity of mapped features, including ages of surface displacements and volcanism, slip rates, recurrence intervals, displacement amounts, and lengths of surface ruptures. Good age control and quantitative activity data are available for relatively few tectonic features in Utah and detailed work is needed in many areas of the state. 157 pages + 2 plates

The major effort of this project was field data collection, data processing, and interpretation for the PACE (Pacific to Arizona Crustal Experiment) seismic experiment. This major cooperative study involved the University of Texas at El Paso, the Air Force Geophysical Lab, the U.S. and Canadian Geological Surveys, Stanford University, the University of Saskatchewan and the University of Arizona. The massive data set gathered during this experiment have been analyzed by a variety of techniques. The results show a gradual thickening of the crust from about 30 km in the Basin and Range to about 40 km along the southwestern margin of the Colorado Plateau. Lateral variations along the transition zone were found to be small. Work along a long profile extending from the Nevada Test Site to White Sands Missile Range included collection of new data, waveform modeling of data from the Albuquerque, NM digital seismograph station and a crustal structure study of western New Mexico. These results document thin (approximately 35 km) crust beneath the central portion of the Rio Grande rift, extension of the lithospheric anomaly associated with this rift well east of the physiographic rift valley a broad transitional zone to thick crust on the western margin of the rift, and delineation of a batholithic mass in the upper crust of western New Mexico.

"Stacking of about 15,500 P-to-S receiver functions recorded at 72 USArray and other broadband seismic stations placed on the Colorado Plateau and the SBRP in Arizona revealed systematic spatial variations in crustal Vp/Vs, crustal thickness and amplitude of P-to-S converted phases. Our results reveal that the BRP is characterized by a thin crust (28.2 ± 0.5 km), a mean Vp/Vs of 1.761 ± 0.014 and a mean amplitude (R) of P - to - S converted wave (relative to that of the direct P wave) of 0.181 ± 0.014 that are similar to a typical continental crust, consistent with the model that the thin crust was the consequence of lithospheric stretching during the Cenozoic. The CP is characterized by the thickest crust (42.3 ± 0.8 km), largest Vp/Vs (1.825 ± 0.009) and smallest R (0.105 ± 0.007) values in the study area. The Colorado Plateau in the study area has the thickest crust and its southern part revealed two layers crustal structure having 12 km thickness of the lower layer. Crust beneath the southern Basin and Range Province is less mafic but thinner than normal continental. The simplest model for the observation is that the Colorado Plateau crust is underlain by a mafic layer which increases both the thickness and Vp/Vs, and decreases the amplitudes of the converted phases by reducing the velocity contrast between the crust and mantle. The results are in general agreement with previous studies (e.g. Frassetto et al., 2006; Gilbert et al., 2007). We hypothesize that the lower crustal layer, which has an anomalously large density as revealed by gravity modeling and high velocities in seismic refraction lines, contributed to the long-term stability and pre-uplift low elevation of the Colorado Plateau in the study area"--Abstract, leaf iv.
