Revised heat flow map of Colorado

Description: This present map of Colorado is a revision of the heat flow map published by Pearl and others in 1976. The heat flow values were gathered from previously published reports. The parameters necessary to compute the heat flow values are described. Regionally, Colorado is separated into three heat flow provinces. They are: the Great Plains, the Southern Rocky Mountains, and the Colorado Plateau provinces. The Great Plains province, except for the Raton Basin and Canon City Embayment, indicates normal heat flow. The Southern Rocky Mountain province which encompasses both the Rio Grande Rift and an anomalous zone located near Ouray are the most promising areas for high heat flow. The Colorado Plateau province is considered normal to slightly above normal compared with the regional heat flow of the United States.

A national strategy for the export of US geothermal technology

Description: This document presents a proposal for an explicit US strategy to focus this still diffuse interest into a coordinated effort by the public and private sectors to increase exports of US geothermal goods and services over the next five to ten years. This document summarizes the background and need for an explicit US strategy, the factors influencing the development of this strategy, strategy options, and a recommended strategy.

Regional operations research for geothermal development in the state of California

Description: A system of regional operations research activities is described which will formulate potential future development scenarios for geothermal energy and identify the public initiatives necessary for that potential. The specifics of the work plan for the state of California are outlined along with the project management structure and reporting schedules. (MHR)

Eastern Gulf Coastal Plain: a scenario for geothermal energy development

Description: A scenario for the development of potential geothermal resources in the Eastern Gulf Coastal Plain states of Mississippi, Alabama and Florida is explained and discussed. A description of the resources and the nature of the potential applications and energy market in this region are given. A ranking of the resources as to their energy content, potential market, etc., is described, and the assumptions and strategy used to generate the scenario are discussed. A more complete report on the detailed aspects involved in the preparation of the development scenario will be issued in the near future.

Map and table showing distribution of known thermal springs in selected igneous rocks in Central Alaska

Description: Thirty-four thermal springs are known to occur in the central Alaska region covered by this map. These springs of central Alaska are spatially associated with granitic plutons of late Mesozic and early Cenozoic, especially with their contact zones. (MHR)

Comprehensive tables giving physical data and thermal energy estimates for young igneous systems of the United States

Description: Two tables are presented. The first is a comprehensive table of 157 young igneous systems in the western United States, giving locations, physical data, and thermal energy estimates, where appropriate for each system. The second table is a list of basaltic fields probably less than 10,000 years old in the western United States.

Heat flow and subsurface temperature distributions in central and western New York. Final report

Description: Initiation of a geothermal energy program in western and central New York requires knowledge of subsurface temperatures for targeting areas of potential resources. The temperature distribution in possible geothermal reservoirs, calculated from heat flow measurements and modeling techniques, shows that a large area of New York can be considered for exploitation of geothermal resources. Though the temperatures at currently accessible depths show the availability of only a low-temperature (less than 100/sup 0/C), direct-use resource, this can be considered as an alternative for the future energy needs of New York State. From analysis of bottom-hole-temperature data and direct heat flow measurements, estimates of temperatures in the Cambrian Sandstones provide the basis of the economic evaluation of the reservoir. This reservoir contains the extractable fluids needed for targeting a potential geothermal well site in the low-temperature geothermal target zone. In the northern section of the Appalachian basin, reservoir temperatures in the Cambrian are below 50/sup 0/C but may be over 80/sup 0/C in the deeper parts of the basin in southern New York State. Using a minimum of 50/sup 0/C as a useful reservoir temperature, temperatures in excess of this value are encountered in the Theresa Formation at depths in excess of 1300 meters. Considering a maximum depth for economical drilling to be 2500 meters with present technology, the 2500 meters to the Theresa (sea level datum) forms the lower limit of the geothermal resource. Temperatures in the range of 70/sup 0/C to 80/sup 0/C are predicted for the southern portion of New York State.

Age and location of volcanic centers less than or equal to 3. 0 Myr old in Arizona, New Mexico and the Trans-Pecos Area of West Texas

Description: This map is one of a series of maps designed for hot dry rock geothermal assessment in Arizona, New Mexico, and the Trans-Pecos area of west Texas. The 3.0 m.y. cutoff age was selected because original heat has probably largely dissipated in older rocks. The location of volcanic centers is more important to geothermal resource assessment than the location of their associated volcanic rocks; however, ages have been determined for numerous flows far from their source. Therefore, the distribution of all volcanic rocks less than or equal to 3.0 m.y. old, for which there is at least one determined age, are shown. Location of the volcanic vents and rocks were taken from Luedke and Smith (1978).

Land- and resource-use issues at the Valles Caldera

Description: The Valles Caldera possesses a wealth of resources from which various private parties as well as the public at large can benefit. Among the most significant of these are the geothermal energy resource and the natural resource. Wildlife, scenic, and recreational resources can be considered components of the natural resource. In addition, Native Americans in the area value the Valles Caldera as part of their religion. The use of land in the caldera to achieve the full benefits of one resource may adversely affect the value of other resources. Measures can be taken to minimize adverse affects and to maximize the benefits of all the varied resources within the caldera as equitably as possible. An understanding of present and potential land and resource uses in the Caldera, and who will benefit from these uses, can lead to the formulation of such measures.
