Available in PDF, EPUB and Kindle. Book excerpt: The Holocene Ice Springs volcanic field of west-central Utah consists of 0.53 km3 of tholeiitic basalts erupted as a sequence of nested cinder cones and associated lava flows. Whole rock x-ray fluorescence and atomic absorption analysis of ninety-six samples of known relative age document statistically significant inter- and intra-eruption chemical variations. Elemental trends include increases in Ti, Fe, Ca, P, and Sr and decreases in Si, K, Rb, Ni, Cr, and Zr with decreasing age. Microprobe analyses of microphenocrysts of olivine, plagioclase, and Fe-Ti oxides and of groundmass olivine, plagioclase, and clinopyroxene indicate limited chemical variation between mineral assemblages of the eruptive events. Petrographic analyses have identified the presence of minor amounts of silicic xenoliths, orthopyroxene megacrysts, and plagioclase xenocrysts. Potassium-argon determinations establish the existence of excess argon in the basaltic cinder (30.05 x 10−12 moles/gm) and in distal lava flows (8.29 x 10−12 moles/gm) which suggest apparent ages of 16 and 4.3 million years respectively. Strontium isotopic data (Puskar and Condie, 1973) show systematic variations from oldest eruptions (87Sr/86Sr=0.7052) to youngest eruptions (87Sr/86Sr=0.7059).

Download or read book Annotated Geothermal Bibliography of Utah written by and published by Utah Geological Survey. This book was released on 1986-01-15 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bibliography of Utah geothermal references through 1984. These references which directly pertain to a geothermal resources are annotated. The annotations are intended to inform the reader of the information contained in the article, not to summarize the results. Accompanying the bibliography is a list and description of geothermal projects and commercial geothermal developments in Utah from 1966 to the present that have been wholly or partially funded through Federal or State programs. The references listed in the project descriptions are keyed to the bibliography. Most of this work is by government agencies or universities. Private or industry-funded geothermal developments are not listed. The references are indexed geographically either under 1.) United States (national studies), 2.) regional – western United States or physiographic province, 3.) Utah – statewide and regional, or 4.) county. Reports concerning a particular hot spring or thermal area are listed under both the thermal area and the county names.

This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated 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 ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought 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 concerned if the printing and distribution of the volume were handled by an international 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 Corporation 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 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Download or read book Geology of Millard County Utah written by Lehi F. Hintze and published by Utah Geological Survey. This book was released on 2003 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
