Book Description
The petrographic database consists of 705 maceral analyses, reflectance measurements, and density and porosity determinations from Utah coal samples. These data were collected by the Utah Geological Survey from 1982 to 1995. Samples were collected from seven of Utah's 22 coal fields. Coal fields sampled are the Book Cliffs (182 samples), Wasatch Plateau (262 samples), Emery (41 samples), Sego (27 samples), Henry Mountains (173 samples), Kaiparowits Plateau (12 samples), and Coalville (four samples). The data are sorted by coal-field names; within each field the analyses are arranged alphabetically by coal-bed name to facilitate comparison. The aim of the database is to provide the industry with information on petrographic properties of Utah coals. In addition, it should help the coal operators and purchasers to determine the best uses for Utah coals.

Book Description
Radon is a radioactive gas of geologic origin that is an environmental concern because of its link to lung cancer. Radon is derived from the decay of uranium, and can accumulate indoors in sufficient quantities to pose a health hazard to building occupants. Although the influence of non-geologic factors such as construction type, lifestyle, and weather is difficult to measure, geologic factors that influence indoor-radon levels can be quantified to assess the hazard potential. Geologic factors that influence indoor-radon levels have been studied for three areas in northern Utah to indicate where indoor radon may be a hazard and radon-resistant techniques should be considered in new construction. The three areas include the lower Weber River area in Davis and Weber Counties, Tooele Valley in Tooele County, and southeastern Cache Valley in Cache County. These areas all lie in the depositional basin of Pleistocene Lake Bonneville, and display common geologic characteristics which affect their potential for radon hazards. A numerical rating system was used to assess and map the relative radon-hazard potential in the three study areas. A high-hazard potential was typically found along range fronts where uranium concentrations are higher, ground water is deep, and soils are permeable. Although soil-gas and indoor-radon concentrations broadly correlate to mapped hazard potential, the correlation is imperfect because of atmospheric contamination of soil-gas samples, the presence of locally anomalous concentrations of radon which are beyond the resolution of the sampling grid or map scale, and the effects of non-geologic factors which are not considered in this geologic assessment. 56 pages + 1 plate

Book Description
Large, damaging earthquakes can happen in many parts of Utah. Therefore, when choosing where to live in this state, we should be aware of the earthquake risk. It is important to know what potential earthquake hazards exist in an area, and what action we can take to reduce the earthquake risk to ourselves and our families. This brochure introduces homebuyers and others to earthquake hazards so that informed choices can be made when selecting homes, building sites, or hazard-reduction measures.

Book Description
The theme of this proceedings volume is the latest research on geomorphic characteristics and processes associated with natural hazards. Presentations cover a gamut of types of disasters throughout the world, describing research and applications of studies in the U.S. and other countries. The book begins with a collection of papers giving a basic background and philosophy of approaching an understanding of natural disasters. These are followed by papers on natural hazards in coastal areas, mountainous regions, landslides, flooding and the detrimental effects of permafrost. The book should prove valuable in gaining an insight of natural hazards and their geomorphic relations, which is imperative for prudent environmental planning in coping with disasters.

Book Description
The two reports in this Special Study provide critical geologic and paleoseismic information on the Oquirrh fault zone, a Quaternary fault in eastern Tooele County, west-central Utah. The Oquirrh fault zone has long been recognized as a potential source of large earthquakes which could affect military and hazardous waste facilities, nearby towns, and populous areas of the more distant central Wasatch Front. 64 pages + 2 plates

Book Description
This study indicates that wetlands in Tooele Valley are endangered. The threats posed are from drought and increased development due to population growth, which could dramatically affect the amount of water the wetlands receive. -- sticker on back of disc cover.
