  	Citation × Citation Citation Abstract Copy Title: Geothermal Exploration of the Puga and Chumathang Geothermal Fields, Ladakh, India Author: Shanker, R. Puga and Chumathang Geothermal fields are situated near the collided junction of the Indian and Asian Crystal plates and thermal activity in these fields is attributed to the widespread igneous activity of Upper Cretaceous to late Tertiary age. A deep suture zone, recognised in between these two fields and the associated faults provide channels for the upward migration of the thermal fluids. High concentrations of Cl, F, Si02, B, Na, Li, Rb, Cs in thermal fluids signify contribution of magmatic bodies towards heat, and fluid supply. These fields are characterized by high heat flow conditions (13 HFU), abnormal shallow geothermal gradients (0.7 - 2.5 c/m) , high base temperature (220 - 270 C) as obtained by alkalia and Ne-K-Ca geothermometry and low resistivity values (2-20 ohm.m.). Low resistivity zones occupy on an area of three and one sq.km. and extend down to maximum depths of 300 m. and 130 m. at Puga and Chumathang respectively. Shallow drilling (28-130 m.) has established the existence of wet steam reservoirs under moderate pressure (2-4.5 kg/cm^2). Hot fluid (95-135 C) discharges from eight flowing wells ranged from 7.5 to 30 t/h. These thermal fluids are stored in the partly consolidated fluvioglacial deposits of Quarternary to Recent age. The occurrence of a limestone layer in the country rock at Puga brightens the prospects of getting good reservoir at depth. In both these fields two aquifers have been recognised, each having sizeable potential for retaining ground water. The ground water recharge is mainly through snow melt from glaciers in the case of Puga field and principally from Indus river in the case of Chumathangfield Title: Geothermal Exploration of the Puga and Chumathang Geothermal Fields, Ladakh, India Author: Shanker, R.

  	Citation × Citation Citation Abstract Copy Title: Geothermal Potential of the West Boise Area Author: Mink, L.L. Year: 1977 With increased use being placed on natural gas, electricity, petroleum, and coal, alternative forms of energy have been sought to help release the pressures being placed on these resources. Geothermal energy is one of the major alternative forms. In portions of Boise, geothermal resources have been utilized for many years for heating of homes and several state office buildings. Recent investigations in the Boise area have shown that hot water is abundant all along the Boise Foothills. This report discusses two areas showing good potential for future geothermal development. These areas are the Dry Creek Valley and the area between Pierce Gulch and Polecat Gulch. Both areas have water temperatures exceeding 37.8°C. In the Boise area it is found that zones of hot water are associated with some type of structural control. The hot water zones associated with the Dry Creek Valley and the Pierce-Polecat area were found to be located at or near the intersection of major linears mapped along the Boise Foothills. These linears reflect a zone of weakness at depth in the rock allowing warm water to migrate upward from the granitic rock of the Idaho batholith below. By mapping all known fault and linear patterns in the area, it is possible to correlate these zones of weakness with areas of hot water. At the intersection of two or more linears, where fracturing is greatest, the majority of geothermal water has been located Title: Geothermal Potential of the West Boise Area Author: Mink, L.L.

  	Citation × Citation Citation Abstract Copy Title: Geology of the Cove Fort-Sulphurdale KGRA Author: Moore, J.N. Year: 1979 The Cove Fort-Sulphurdale Known Geothermal Resource Area (KGRA) is located on the northwestern margin of the Marysvale volcanic field in southwestern Utah. The geology of the KGRA is dominated by lava flows and ash-flow tuffs of late Oligocene to mid-Miocene age that were deposited on faulted sedimentary rocks of Paleozoic to Mesozoic age. The geothermal system of the Cove Fort-Sulphurdale KGRA is structurally controlled by normal faults. High-angle faults control fluid flow within the geothermal reservoir, while the gravitational glide blocks provide an impermeable cap for the geothermal system in the central part of the field. Surficial activity occurring to the north and south of the glide blocks is characterized by the evolution of hydrogen sulfide and deposition of native sulphur. Intense acid alteration of the aluvium, resulting from downward migration of sulphuric acid, has left porous siliceous residues that retain many of the original sedimentary structures. Detailed logs of Union Oil Company drill holes Forminco No. 1, Utah State 42-7, and Utah State 31-33 are included Title: Geology of the Cove Fort-Sulphurdale KGRA Author: Moore, J.N.

A review of scientific information on issues related to the use and management of water resources in the Pacific Northwest. Gen. Tech. Rep. PNW-GTR-595. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 128 p. Fresh water is a valuable and essential commodity in the Pacific Northwest States, specifically Oregon, Washington, and Idaho, and one provided abundantly by forested watersheds in the region. The maintenance and growth of industrial, municipal, agricultural, and recreational activities in the region are dependent on adequate and sustainable supplies of fresh water from surface and ground-water sources. Future development, especially in the semiarid intermountain area, depends on the conservation and expansion of the region's water resource. This synthesis reviews the state of our knowledge and condition of water resources in the Pacific Northwest. Keywords: Water distribution, flow regimes, water demand, conflicts, tools, water use.
