Ronald G. Worl
1979, Open-File Report 79-1519
The Jabal Ishmas-Wadi Tathlith gold belt is a north-south zone of numerous ancient gold mines in the southeastern Precambrian shield of Saudi Arabia, extending along long 43?30'E. between lat 18?N. and 21?30'N., a distance of about 390 km. The gold belt coincides with a major zone of faulting, shearing, and...

Design of a network for monitoring ground-water quality in Minnesota
Marc F. Hult
1979, Open-File Report 79-1164
A network for monitoring the quality of water in the 13 principal aquifers in Minnesota has been designed and more than 400 wells and springs selected for sampling. The network organization includes four major elements; (1) point sampling, (2) point monitoring, (3) regional monitoring, and (4) site-specific monitoring. These elements...

Ancient mines of the Farah Garan area, southwestern Saudi Arabia
C. W. Smith, H. Richard Blank
1979, Open-File Report 79-1659
Ancient miners, in quest of oxidized copper minerals, gold, silver, and possibly zinc, mined gossans to approximately 20 m depth in an area 1.1 by 0.5 km in extent at Farah Garan. The gossans, derived from sulfides, are ordinarily found at contacts between marble lenses and metavolcanic-metasedimentary rocks, but in...
Summary of hydrologic data collected during 1977 in Dade County, Florida
John E. Hull
1979, Open-File Report 79-514
During 1977 rainfall was 1.52 inches above the long-term average in Dade County, Fla. Ground-water levels ranged from 0.3 foot above to 0.1 foot below average. The highest and lowest ground-water levels for the year were 1 foot below and 1 foot above their long-term average. In the Hialeah-Miami Springs...
Backwater at bridges and densely wooded flood plains, west fork Amite River near Liberty, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1979, Hydrologic Atlas 598
Floodflow data that will provide a base for evaluating digital models relating to open-channel flow were obtained at 22 sites on streams in Alabama, Louisiana, and Mississippi. Thirty-five floods were measured. Analysis of the data indicated methods currently in use would be inaccurate where densely vegetated flood plains are crossed...

A preliminary annotated bibliography on siliceous algal cysts and scales
David P. Adam, Albert D. Mahood
1979, Open-File Report 79-1215
As part of an investigation of the stratigraphic and environmental distributions of siliceous algal resting cysts, we have assembled this bibliography. The emphasis is on papers that illustrate these cysts, and our annotation concentrates on the nature of the illustrations. In some cases, we have also listed taxonomic names of...

Stratigraphic sections of Jurassic San Rafael Group and adjacent rocks in Rio Blanco and Garfield counties, Colorado
James Clifton Wright, Dayton Delbert Dickey
1979, Open-File Report 79-245
These sections were measured prior to 1960, before adoption of the metric system. Publication was delayed by other assignments of the authors and later by the untimely death of J. C. Wright. They are being released at this time because of the increased interest in the uranium potential of Jurassic...
Stratigraphy and paleoenvironment of Miocene phosphatic rocks in the East San Francisco Bay region, California
James M. Hill
1979, Open-File Report 79-1570
A stratigraphic study of the Monterey Group in the East San Francisco Bay Region, California, indicates that a depositional basin began to subside in early to middle Miocene time. The Miocene sea transgressed from the west or southwest, and the area subsided to a possible water depth of 500 to...
Ground-water quality in selected areas of Wisconsin
S. M. Hindall
1979, Open-File Report 79-1594
Analysis of 2,071 ground-water samples from 970 wells throughout Wisconsin indicate large variations in ground-water quality. Ground water in Wisconsin is generally suitable for most uses, but in some areas concentrations of chemical constituents exceed recommended drinking-water standards. Iron, manganese, and nitrate commonly exceed recommended drinking-water standards and dissolved solids,...
Mineral resources of the Big Frog Wilderness Study Area, Polk County, Tennessee and Fannin County, Georgia

1979, Open-File Report 79-1209
The proposed Big Frog Wilderness is comprised of approximately 1820 hectares (18.2 km2) of mountainous terrain in the Cherokee and Chattahoochee National Forests south of the Ocoee River in Polk County, Tennessee, and Fannin County, Georgia. Rocks of the study area are greenschist-facies metasandstone, meta-arkose, metagraywacke, and dark slate of...

Earth fissures and localized differential subsidence
Thomas L. Holzer, Earl Haig Pampeyan
1979, Open-File Report 79-951
Long tension cracks caused by declines of ground-water level at four sites in Arizona, California, and Nevada occur at points of maximum, convex-upward curvature in subsidence profiles based on relevelings of closely-spaced bench marks aligned perpendicular to the cracks. We conclude the cracks are caused by horizontal strains associated with...
