The design of a microprocessor-based data logger
K.J. Leap, L.A. Dedini
1982, Open-File Report 82-167
The design of a microprocessor-based data logger, which collects and digitizes analog voltage signals from a continuous-measuring instrumentation system and transmits serial data to a magnetic tape recorder, is discussed. The data logger was assembled from commercially-available components and can be user-programmed for greater flexibility. A description of the data...
Radioactive mineral spring precipitates, their analytical and statistical data and the uranium connection
R. A. Cadigan, J.K. Felmlee
1982, Open-File Report 82-743
Major radioactive mineral springs are probably related to deep zones of active metamorphism in areas of orogenic tectonism. The most common precipitate is travertine, a chemically precipitated rock composed chiefly of calcium carbonate, but also containing other minerals. The mineral springs are surface manifestations of hydrothermal conduit systems which extend...
Electrical studies at the proposed Wahmonie and Calico Hills nuclear waste sites, Nevada Test Site, Nye County, Nevada
D.B. Hoover, Michael P. Chornack, K.H. Nervick, M. M. Broker
1982, Open-File Report 82-466
Two sites in the southwest quadrant of the Nevada Test Site (NTS) were investigated as potential repositories for high-level nuclear waste. These are designated the Wahmonie and Calico Hills sites. The emplacement medium at both sites was to be an inferred intrusive body at shallow depth; the inference of the...
Preliminary report on the geology and gold mineralization of the Gold Basin-Lost Basin mining districts, Mohave County, Arizona
Ted G. Theodore, Will N. Blair, J. Thomas Nash, Edwin H. McKee
1982, Open-File Report 82-1052
The Gold Basin-Lost Basin mining districts are adjacent to each other in northwestern Arizona, south of Lake Mead, and just west of the Grand Wash Cliffs. Most recorded production from lode deposits is credited to mines in the Gold Basin district, which is in the southern White Hills, whereas the...
Geochemical orientation for mineral exploration in the Hashemite Kingdom of Jordan
W.C. Overstreet, D. J. Grimes, J. F. Seitz
1982, Open-File Report 82-791
This report is a supplement to previous accounts of geochemical exploration conducted in the Hashemite Kingdom of Jordan by the Natural Resources Authority of the Royal Government of Jordan and the U.S. Geological Survey. The field work on which this report is based was sponsored by the U.S. Agency for...
High-resolution seismic-reflection profiles collected aboard R/V GYRE, cruise GYRE 80-G-7A, over the continental slope and upper continental rise, offshore New Jersey
J.C. Hampson Jr.
1982, Open-File Report 82-305
During August 1980, the U.S. Geological Survey (USGS) collected 982 km of single-channel seismic-reflection data on the Continental Slope and upper Rise between Lindenkohl Canyon and Toms Canyon, off New Jersey (fig. 1). The work was conducted aboard R/V GYRE (cruise 80-G-7A). The trackline grid of this cruise extends and...
A hybrid structure for the storage and manipulation of very large spatial data sets
Donna J. Peuquet
1982, Open-File Report 82-816
The map data input and output problem for geographic information systems is rapidly diminishing with the increasing availability of mass digitizing, direct spatial data capture and graphics hardware based on raster technology. Although a large number of efficient raster-based algorithms exist for performing a wide variety of common tasks on...
