Available in PDF, EPUB and Kindle. Book excerpt: The low-temperature geothermal resources of north-central Box Elder County, Utah were assessed. Exploration techniques used included chemical analyses of water from wells and springs, temperature surveys, and temperature-depth measurements in unused wells within the study area. The highest water temperatures (31°, 30°, and 29°C) recorded in this research were located in three separate geographic regions, suggesting that no single warm water occurrence dominates the study area. Total dissolved solid (TDS) concentrations ranged from 294 to 11,590 mg/l. Areas of warm water occurrences generally had TDS values of greater than 1100 mg/l. Reservoir temperatures were estimated using chemical geothermometers. Calculated temperatures ranged between 50° and 100°C. Temperature-depth measurements were logged in 16 unused wells. Thermal gradients calculated from the profiles ranged from isothermal to 267°C/km. The background gradient for the study area appears to be slightly above the average Basin and Range gradient of 35°C/km. The highest gradients were calculated for the area approximately eight kilometers west of Snowville, Utah, which is also an area of warm water. 61 refs., 15 figs., 6 tabs.

Download or read book Low temperature Geothermal Assessment of the Jordan Valley Salt Lake County Utah written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two known low-temperature areas (Warm Springs fault and Crystal Hot Springs) are located in the Jordan Valley, but the primary purpose of this report is to locate other low-temperature resources not previously identified. Geothermal reconnaissance techniques utilized in this study include a temperature survey and chemical analysis of wells and springs, and temperature-depth measurements in holes of opportunity. Also, further site specific gravity modelling for the Warm Springs fault geothermal area and initial modelling for the entire valley were also conducted. Areas identified as having potential low-temperature geothermal resources at depth are: (1) the north-central valley area; (2) an east-west portion of the central valley; and (3) a north-south oriented area extending from Draper to Midvale. Each of these areas exhibits ground-water temperatures 20/sup 0/C or greater. Each area has thermal wells with common ion characteristics similar to both Crystal Hot Springs and the Warm Springs fault geothermal systems. Significant concentrations of Sr, Li, B, and F are present in many of these wells.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Geothermal reconnaissance techniques have identified five areas in Utah County warranting further investigation for low-temperature geothermal resources. One area in northern Utah Valley is along Utah Lake fault zone and includes Saratoga Hot Springs. Water temperatures within this area range from 21 to 43°C. Common ion analyses as well as B and Li concentrations indicate waters sampled in this area are anomalous when compared to other samples from the same aquifer. Two other areas in southern Utah Valley also coincide with the Utah Lake fault zone. Common ion analyses, trace element concentrations, and C1/HCO3 ratios distinguish these areas from all other waters in this valley. Temperatures within these southern areas range from 21 to 32°C. All three thermal areas are possibly the result of deep circulation of meteoric water being warmed and subsequently migrating upward within the Utah Lake fault zone. The Castilla Hot Springs area has been expanded by this study to include a spring located 3 mi further up Spanish Fork Canyon near the Thistle earthflow. A temperature of 50°C was recorded for this spring and chemistry is similar to Castilla. In Goshen Valley, the fifth geothermal area identified, measured temperatures range from 20 to 27°C for some wells and springs. Chemical analyses, however, do not discern the location of low-temperature geothermal reservoirs. 18 refs., 7 figs., 5 tabs.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1980 and 1981 a total of 569 new gravity stations were taken in Utah and Goshen Valleys and adjacent areas, Utah. The new stations were combined with 530 other gravity stations taken in previous surveys which resulted in a compilation of 1099 stations which were used in this study. The additional surveys were undertaken to assist in the evaluation of the area for the possible development of geothermal resources by providing an interpreted structural framework by delineating faults, structural trends, intrusions, thickness of valley fill, and increased density of host rock. The gravity data are presented as (1) a complete Bouguer gravity anomaly map with a 2 mgal contour interval on a scale of 1:100,000 and (2) five generally east-trending gravity profiles. A geologic interpretation of the study area was made from the gravity map and from the interpretive geologic cross sections which were modeled along the gravity profiles.

This book was released on 1979 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: To evaluate the geothermal energy potential of the hot springs system near Midway, Wasatch Co., Utah, consideration was given to heat flow, water chemistry, and structural controls. Abnormal heat flow was indicated qualitatively by snow-melt patterns and quantitatively by heat-flow measurements that were obtained from two of four temperature-gradient wells drilled in the area. These measurements indicated that the area north of the town of Midway is characterized by heat flow equal to 321.75 MW/m2, which is over four times the value generally considered as normal heat flow. Chemical analyses of water from six selected thermal springs and wells were used in conjunction with the silica and Na-K-Ca geothermometers to estimate the reservoir temperature of the thermal system. Because the calculated temperature was more than 25°C above the maximum observed temperature, a mixing model calculation was used to project an upper limit for the reservoir temperature. Based on these calculations, the system has a reservoir temperature ranging from 46 to 125°C. Structural information obtained from published geologic maps of the area and from an unpublished gravity survey, enabled two models to be developed for the system. The first model, based on geologic relationships in the mountains to the north and west of Midway, assumes that the heat for the thermal system comes from a relatively young intrusive or related hydrothermal convection system in the vicinity of the Mayflower mine. Meteoric waters would be heated as they approach the heat source and then move laterally to the south through faults and fractures in the rocks. These thermal waters then rise to the surface through fractures in the crest of an anticline underneath the Midway area. The second model, based on the gravity survey, assumes an igneous intrusion directly beneath Midway as the heat source.

Available in PDF, EPUB and Kindle. Book excerpt: The San Rafael Swell is an anticline, or a geological uplift, that originally looked like an oval bowl turned upside down. Over time it has been carved into castle-like formations and deep canyons by erosive conditions. This landscape seemed so formidable to early cartographers that it was the last area in the continental United States to be mapped. The San Rafael Swell itself has no permanent human inhabitants, but small towns are scattered along its northern and eastern borders where first American Indians and later cowboys, ranchers, and miners made their homes. The hardy settlers of these towns familiarized themselves with what they called "the Desert" and gradually discovered its treasures and its secrets.
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.
Download or read book Vertebrate Paleontology in Utah written by David D. Gillette and published by Utah Geological Survey. This book was released on 1999 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.

Book excerpt: Investigations about porosity in petroleum reservoir rocks are discussed by Schmoker and Gautier. Pollastro discusses the uses of clay minerals as exploration tools that help to elucidate basin, source-rock, and reservoir history. The status of fission-track analysis, which is useful for determining the thermal and depositional history of deeply buried sedimentary rocks, is outlined by Naeser. The various ways workers have attempted to determine accurate ancient and present-day subsurface temperatures are summarized with numerous references by Barker. Clayton covers three topics: (1) the role of kinetic modeling in petroleum exploration, (2) biological markers as an indicator of depositional environment of source rocks and composition of crude oils, and (3) geochemistry of sulfur in source rocks and petroleum. Anders and Hite evaluate the current status of evaporite deposits as a source for crude oil.

Available in PDF, EPUB and Kindle. Book excerpt: Microbial carbonates (microbialites) are remarkable sedimentary deposits because they have the longest geological range of any type of biogenic limestones, they form in the greatest range of different sedimentary environments, they oxygenated the Earth’s atmosphere, and they produce and store large volumes of hydrocarbons. This Special Publication provides significant contributions at a pivotal time in our understanding of microbial carbonates, when their economic importance has become established and the results of many research programmes are coming to fruition. It is the first book to focus on the economic aspects of microbialites and in particular the giant pre-salt discoveries offshore Brazil. In addition it contains papers on the processes involved in formation of both modern and ancient microbialites and the diversity of style in microbial carbonate buildups, structures and fabrics in both marine and non-marine settings and throughout the geological record.
