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 probably indicat

The area of influence of an exploratory hole
A method is presented for calculating the area of influence of exploratory drill holes by using the size and shape of resource targets. The solution presented is for elliptical and circular targets, but the method is applicable to any shaped target. The degree to which points have been explored depends upon their distance away from a drill hole and the possible orientations of the target. Several

Natural remanent magnetization, mag¬netic properties, and oxidation of titanomagnetite in basaltic rocks from DSDP Leg 34
We have made paleomagnetic measurements and investigated the magnetic mineralogy of 24 samples of basalt and diabase from Sites 319, 320, and 321 on the Nazca plate. Sample distributions, locations, and ages of overlying sediments are as follows: Site 319, Hole 319, lat 13°01.04'S, long 101°31.46'W, 2 samples, early Miocene (N8); Site 319, Hole 319A, (same coordinates and age), 12 samples. Site 32

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 (36 to 33 m

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 this asp

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 specified

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 variation
