Workshop on Electrical Methods in Geothermal Exploration

Description: The objectives of the workshop are: (1) to disseminate case histories of the application of electrical methods in the geothermal environment; (2) to disseminate information from theoretical and field studies bearing on the relative merits of the reconnaissance electrical methods such as MT/AMT, Tellurics, Bipole-dipole, and self-potential; (3) to disseminate information from theoretical and field studies bearing on the relative merits of the detailed electrical methods such as downhole-to-surface methods, Schlumberger resistivity, electromagnetics; (4) to make studies of the cost-effectiveness of reconnaissance versus detailed electrical methods; (5) to analyze the preferred location and/or locations of electrical methods in typical exploration architecture; (6) to develop goals for specific theoretical and field comparisons of the cost-effectiveness and resolution of the various electrical methods; (7) to develop goals for advances in (a) equipment, (b) data processing, and (c) data interpretation of electrical methods applied in the geothermal environment; and (8) to discuss the advantages and limitations of electrical methods in the search for geothermal resources.

Recurrent Tropidoleptus Zones of the Upper Devonian in New York

Description: From introduction: This report describes the four zones, three well-marked and one subordinate, in the Upper Devonian rocks, each of which contained several species that are common in the typical Hamilton formation of the Cayuga Lake section and are associated with very few of the really characteristic species of the faunas normal to the formations in which they are found.

The Lance Formation: Petrography and Stratigraphy, Powder River Basin and Nearby Basins, Wyoming and Montana

Description: From abstract: The uppermost Cretaceous Lance Formation was studied in the Powder River Basin and nearby basins of Wyoming and Montana. The Lance Formation is overlain by the continental Paleocene Fort Union Formation. This report is a petrography and stratigraphy study on these basins.

Preliminary Report on the Geology and Water Resources of Central Oregon

Description: From introduction: The observations recorded in this paper were made during a rapid reconnaissance from east to west through the central part of Oregon in the summer of 1903, and are in continuation of similar work in the same general region previously done by the author, reports concerning which have been published.

Reconnaissance for Uraniferous Rocks in Northeastern Wind River Basin, Wyoming

Description: From abstract: A reconnaissance search for uraniferous rocks in the northeastern part of the Wind River Basin was made in July and August 1951 in the course of other work. In addition to Tertiary tuffs and associated lignite, coal, and carbonaceous rocks, some radioactivity anomalies, chiefly in granite, which had been detected by airborne equipment in November 1950, were checked on the ground. A tuff of middle or late Eocene age containing 0.003 percent uranium was as high in uranium as any rock found.

Preliminary Report on the Ketchikan Mining District, Alaska, with an Introductory Sketch of the Geology of Southeastern Alaska

Description: From introduction: Since 1898 the United States Geological Survey has been carrying on a systematic investigation of the mineral resources of Alaska.As the northern mining districts of southeastern Alaska had already been the subject of an investigation by Dr. Becker in 1895,a and as the Ketchikan district was being rapidly developed, it was decided to spend the greater part of the short season in the Ketchikan district and in the fall to make a more hasty reconnaissance of the northern belt, in order to obtain a general familiarity with the region and, if possible, to establish some correlations. This plan was carried out, and the results of the work are embodied in the following report.

A Reconnaissance of the Northwestern Portion of Seward Peninsula, Alaska

Description: From introduction: In response to an urgent demand by the public, the Geological Survey, in 1900, undertook a topographic and geologic reconnaissance of the southern half of the Seward Peninsula.( The area mapped embraced the more important gold fields of the peninsula. The topographic map made in 1900 included the drainage of Bering Sea from Cape Darby to Port Clarence, the southern drainage of Grantley Harbor and Imuruk Basin, and the northern drainage of Norton Sound. A geologic reconnaissance was also made of the York mining district and of part of the Kuzitrin drainage.

Mineralogy and Stratigraphy of the Lower Part of the Pierre Shale, South Dakota and Nebraska

Description: From abstract and introduction: Mineralogic and stratigraphic studies of the lower part of the Pierre Shale of Late Cretaceous age along the Missouri River indicate correlations different from those generally accepted. The purposes of this paper are to present evidence for the new correlations and to resolve problems of formal nomenclature that result from them.

Jurassic (Bathonian and Callovian) Ammonites in Eastern Oregon and Western Idaho

Description: From abstract: Jurassic ammonites of late Bathonian to middle Callovian Age have been found in 12,000-13,000 feet (3,660-3,960 m) of strata exposed in the area near and south of Izee and Seneca in east-central Oregon. Ammonites of early Callovian Age and possibly also late Bathonian Age occur in several hundred feet of black shale exposed along Dennett Creek near Mineral, Idaho. Early Callovian ammonites also occur in similar black shale exposed on the Oregon side of Snake River Canyon about 32 miles (52 km) south of the northeast corner of Oregon.

Some Middle Cenomanian (Upper Cretaceous) Acanthoceratid Ammonites from the Western Interior of the United States

Description: Abstract: The ammonite family Acanthoceratidae de Grossouvre is represented in the Western Interior region by many genera. Species and subspecies of Calycoceras, Acanthoceras, Cunningtoniceras, Plesiacanthoceras, and Protacanthoceras are important guide fossils to narrow zones of middle Cenomanian age in southeastern Montana, northeastern Wyoming, western South Dakota, and central Kansas. In this region, the ammonite zonation through most of the middle Cenomanian seems to be, from oldest to youngest, a zone of Acanthoceras muldoonense Cobban and Scott, a zone of Acanthoceras bellense Adkins and Calycoceras leonense (Adkins), a zone of Cunningtoniceras amphibolum (Morrow) with subzones of C. amphibolum amphibolum and C. amphibolum fallense (n. subsp.), and a zone of Plesiacanthoceras wyomingense (Reagan). In this report, Acanthoceras muldoonense, A. bellense, and Calycoceras leonense are described from the northern part of the Western Interior for the first time. Cunningtoniceras amphibolum, originally assigned to Acanthoceras, is described in more detail and divided into the nominate subspecies and the new subspecies C. amphibolum fallense. The earliest whorls of Plesiacanthoceras wyomingense, previously unknown, are described as well as all the later growth stages. The small genus, Protacanthoceras, is represented by several new species and one new subspecies. Protacanthoceras fisheri is found in the zone of Acanthoceras bellense, P. vetula occurs in the subzone of Cunningtoniceras amphibolum amphibolum, and P. hosei hosei and P. hosei sheridanense are found in the subzone of C. amphibolum fallense. Protacanthoceras alzadense is associated with Plesiacanthoceras wyomingense.
