  	Citation × Citation Citation Abstract Copy Title: Utilization of geothermal energy in the mining and processing of tungsten ore: Final report Author: Erickson, M.V. Year: 1981 The engineering, economic, and environmental feasibility of the use of low and moderate temperature geothermal heat in the mining and processing of tungsten ore is explored. The following are covered: general engineering evaluation, design of a geothermal energy system, economics, the geothermal resource, the institutional barriers assessment, environmental factors, an alternate geothermal energy source, and alternates to geothermal development.

  	Citation × Citation Citation Abstract Copy Title: Hawaii Geothermal Resource Assessment Program: western state cooperative direct heat resource assessment, Phase I. Final report Year: 1978 A regional geothermal resource assessment has been conducted for the major islands in the Hawaiian chain. The assessment was made through the compilation and evaluation of the readily accessible geological, geochemical, and geophysical data for the Hawaiian archipelago which has been acquired during the last two decades. The geologic criteria used in the identification of possible geothermal reservoirs were: age and location of most recent volcanism on the island and the geologic structure of each island. The geochemical anomalies used as traces for geothermally altered ground water were: elevated silica concentrations and elevated chloride/magnesium ion ratios. Geophysical data used to identify subsurface structure which may have geothermal potential were: aeromagnetic anomalies, gravity anomalies, and higher than normal well and basal spring discharge temperatures. Geophysical and geochemical anomalies which may be the result of subsurface thermal effects have been identified on the islands of Hawaii, Maui, Molokai and Oahu; DOE/ID/01713-4 Title: Hawaii Geothermal Resource Assessment Program: western state cooperative direct heat resource assessment, Phase I.

  	Citation × Citation Citation Abstract Copy Title: Washington: A Guide to Geothermal Energy Development Author: Bloomquist, R.G. Year: 1980 A brief overview is given of the geological characteristics of each region of the state as they relate to potential geothermal development. Those exploration methods which can lead to the siting of a deep exploration well are described. Requirements and techniques needed for drilling deeper higher temperature exploration and production wells are presented. Electrical generation, direct utilization, and indirect utilization are reviewed. Economic factors of direct use projects are presented. A general guide to the regulatory framework affecting geothermal energy development is provided. The general steps necessary to gain access to explore, develop, distribute, and use geothermal resources are outlined (MHR) Title: Washington: A Guide to Geothermal Energy Development Author: Bloomquist, R.G.
