This book was released on 1984 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Magic Reservoir area straddles the Blaine-Camas county line in south-central Idaho, along the northern boundary of the central Snake River Plain. The rocks exposed at Magic Reservoir include a 5.98 ± 0.69 m.y. old rhyolite flow, the Pliocene Square Mountain basalt, multiple cooling units of 5.85 ± 0.23 m.y. old rhyolite ash-flow tuff, a 4.94 ± 0.29 m.y. old rhyolite dome, and Quaternary basalt flows and sediments. These newly reported ages for the rhyolites at Magic Reservoir reveal that they are the youngest, westernmost silicic volcanic rocks presently known in the Snake River Plain. They represent an anomalously young rhyolitic event that may include the Moonstone Mountain rhyolite dome to the northwest and the previously dated (Armstrong and others, 1975) 3.06 ± 0.04 m.y. old Wedge Butte rhyolite dome to the southeast of Magic Reservoir. The area is cut by numerous normal faults trending northwest, northeast, and west. The northwest-trending faults are the dominant structures. They form a horst block at Hot Springs Landing and parallel the regional structural grain. The geothermal resource at Magic Reservoir occurs within the elevated heat flow province at the northern margin of the Snake River Plain. The system is probably controlled by deep, convective circulation of fluids along faults at the intersection of the Hot Springs Landing horst with west- and northeast-trending fractures. Although the volcanic rocks in the Magic Reservoir area are young, they are too old to contribute any magmatic heat to the geothermal system.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal waters of the east-west trending intermontane basin making up the Camas Prairie area were sampled during the fall of 1973. Average ground water temperature is 15°C (10°C above mean annual temperature). The thermal waters, chemically similar to thermal waters discharging from granitic rocks elsewhere in Idaho, have high pH, high Na/K and Na/Ca ratios, and high fluoride content. They are low in total dissolved solids (less than 365 mg/l), low in chloride, and exhibit relatively constant chloride/fluoride ratios and silica concentrations. Geochemical thermometers are interpreted to indicate that maximum aquifer temperatures in the Camas Prairie Basin are only about 100°C, although higher temperatures were predicted by the quartz equilibrium geochemical thermometer and mixing models. The Magic Hot Springs well, located near the north shore of the Magic Reservoir at Hot Springs Landing, is an exception to these general conclusions. These waters may be circulating to depths approaching 1,800 to 2,500 m along faults or fissures; or may be due to leakage from an aquifer or reservoir heated by a shallow heat source, related perhaps to the Holocene basalt flows south of Magic Reservoir. These waters are nearly neutral in pH, are much higher in dissolved solids, exhibit higher chloride/fluoride, chloride/carbonate plus bicarbonate, and chloride/sulfate ratios, and are, in general, chemically dissimilar to thermal waters elsewhere in the area. Temperatures predicted by geochemical thermometers are thought to indicate that Magic Hot Springs well waters are ascending from an aquifer or reservoir with temperatures from 140° to 200°C. Temperatures in this range would be sufficient for application in many industrial processes, including power generation, should sufficient water be available.
