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).

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.

Book excerpt: It is the only absolute desert in North America, a four-hundred-square-mile dry lake bed so desolate that nothing ever grows there. Vast and featureless, Nevada's Black Rock Desert defies visual measurementÑmuch to the consternation of off-roaders who venture out onto this playa only to run out of gas before reaching the other side. It is the largest flat area on the continent, where the sound barrier was broken in a car. And it is a place of total silenceÑnot even birds or insects live hereÑexcept when thousands of humans congregate for the Burning Man Festival on Labor Day weekend. Writer and poet William Fox has demonstrated his familiarity with the Great Basin in such respected books as Mapping the Empty, just as Mark Klett has been documenting the landscape of the American West in his acclaimed photographic studies. Now these accomplished artists turn their combined talents to an appreciation of this desolate corner of North America, where the only change in scenery comes with the shifting pattern of cracks in the earth after seasonal rains. The Black Rock Desert is a philosophical and visual meditation on an extraordinary place virtually devoid of the usual physical features one relies on for orientation and comfort. It invites readers to consider how the mind responds to a place so empty that it's both physically overpowering and psychically disorienting. Klett's photographs are austere yet innovative, admitting the vastness of the desert yet never letting us forget that traces of human passage and perception are ubiquitous. Fox's contemplative essays bring us news of both the natural desert and its cultural occupation, from the explorations of John C. FrŽmont to the exaltations of Burning Man. Together, Fox and Klett have forged an introspective guide to a place so daunting that few dare to venture there alone. For anyone seeking to understand how and why we perceive deserts the way we do, their book charts the rugged intersection of the American landscape and the human spirit.

Available in PDF, EPUB and Kindle. Book excerpt: Aeromagnetic and gravity surveys were conducted during 1978 in the Black Rock Desert, Utah over an area of about 2400 km2 between the north-trending Pavant and Cricket Mountains. The surveys assisted in evaluating the geothermal resources in the Meadow-Hatton Known Geothermal Resource Area (KGRA) and vicinity by delineating geophysical characteristics of the subsurface. The gravity measurements from approximately 700 new stations were reduced to complete Bouguer gravity anomaly values with the aid of a computerized terrain-correction program and contoured at an interval of 1 milligal. The aeromagnetic survey was drape flown at an altitude of 305 m (1000 ft) and a total intensity residual aeromagnetic map with a contour interval of 20 gammas was produced. Two gravity and aeromagnetic east-west profiles and one north-south profile were modeled using a simultaneous 2 1/2-dimensional modeling technique to provide a single model satisfying both types of geophysical data.
