A geochemical study of oil in metalliferous veins, Idarado Mine, San Juan Mountains, Colorado A geochemical study of oil in metalliferous veins, Idarado Mine, San Juan Mountains, Colorado
A tarry, benzene-soluble material is present in metal-rich veins in the Idarado mine, Ouray County, Colo., in an area not known to have petroleum resources. The material was compared chemically, spectometrically, and chromatographically with oils from four fields in the nearby Paradox basin. Each of these oil fields contains reservoir rocks equivalent to rock units known to extend...

Geology and geophysics of the southern Raft River Valley geothermal area, Idaho, USA Geology and geophysics of the southern Raft River Valley geothermal area, Idaho, USA
The Raft River valley, near the boundary of the Snake River plain with the Basin and Range province, is a north-trending late Cenozoic downwarp bounded by faults on the west, south, and east. Pleistocene alluvium and Miocene-Pliocene tuffaceous sediments, conglomerate, and felsic volcanic rocks aggregate 2 km in thickness. Large gravity, magnetic, and total field resistivity highs...

The Oligocene volcanic center at Eureka, Nevada The Oligocene volcanic center at Eureka, Nevada
A volcanic center covering an area of about 80 km2 near Eureka, Nev., and active in the early Oligocene, is characterized by rhyolitic, rhyodacitic. and andesitic pyroclastic rocks, lava flows, and shallow intrusive bodies. These rocks were emplaced as intertonguing and interpenetrative units during a 5-m.y. interval; most of the volcanism was in the last 3 million years of this period...

Expectations, market structure, and sequential bid pricing Expectations, market structure, and sequential bid pricing
Public agencies are frequently constrained to procure goods and services in sealed tender markets. Pricing decisions of firms participating in such markets have been analyzed for both static and dynamic situations. As might be anticipated, the decision rules obtained in these analyses depend in an integral way on the firm's perception of the behavior of other market participants. It is...

An empirical note on firm performance in government contract markets An empirical note on firm performance in government contract markets
Public construction and, in particular, highway construction account for a large proportion of the non-defense expenditures by the government. Con- tracts for highway construction are let almost exclusively through a sealed tender process. Competitive bidding is used to encourage price competition. There is, however, a problem in insuring that the bidder is able to deliver the product of...

Regional impact of water resource investments in an developing area Regional impact of water resource investments in an developing area
Regional development and industrialization patterns are investigated and related via regression analysis to water resource investments for the island of Puerto Rico. Although results of this study indicate such investments have little immediate or short‐term impact, significant relationships and variations in regional responses appear over longer time periods. This is shown by applying a...

Physical factors determining the fraction of stored energy recoverable from hydrothermal convection systems and conduction-dominated areas Physical factors determining the fraction of stored energy recoverable from hydrothermal convection systems and conduction-dominated areas
This report contains background analyses for the estimates of Nathenson and Muffler (1975) of geothermal resources in hydrothermal convection systems and conduction-dominated areas. The first section discusses heat and fluid recharge potential of geothermal reservoirs. The second section analyzes the physical factors that determine the fraction of stored energy obtainable at the surface...
