The status of mineral resource information on the major land withdrawals of the Alaska Native Claims Settlement Act of 1971

This report is an analysis of the adequacy of the present level of geologic knowledge for making mineral resource potential evaluations of 126 federal land withdrawals made under the Alaska Native Claims Settlement Act. The withdrawals considered are Native village and regional deficiency areas (Sec. 11.A.3, ANCSA), classification and national interest study areas for possible inclusion in the four national systems (Sec. 17.d.2) and classification and public interest areas (Sec. 17.d.1). Neither prior withdrawals, utility corridors, state selections, open lands, or Indian Reserves are included. Native village withdrawals are also not included because they were the subject of an earlier report (Cobb, E. H., and Trollman, W. T., 1971). The present report consists of two sections. The introduction explains the method of preparation and presents a summary table and some general remarks on the mineral potential of Alaska. The second part, the discussion of withdrawals, contains listings of the investigations that have been made and analyses of their adequacy in view of what needs to be known about the withdrawals.

Outer Continental Shelf Oil and Gas Information Program: Pacific index (January 1962-October 1980)

The United States is currently engaged in an effort to develop the oil and gas resources of the Outer Continental Shelf (OCS). In the Pacific, State jurisdiction extends for 3 geographical (nautical) miles (5.56 km) from the coastline. The OCS, which comprises the submerged lands of the Continental Shelf seaward of the California, Oregon, and Washington State boundaries, is under Federal jurisdiction. Activities occurring offshore must be supplied and supported from land, and the onshore activities required may have significant effects on the communities in which they occur. For example, oil and gas production might involve the expansion of existing transportation and processing facilities and the construction of new ones, and it might trigger an influx of workers and change employment patterns. These effects, in turn, could influence regional income, demand on public services, tax revenues, and air and water quality.

Background hydrologic information in potential lignite mining areas in Mississippi, August 1980

The U.S. Geological Survey in cooperation with Mississippi Bureau of Geology is conducting a hydrologic data-collection program in the potential lignite-producing areas in Mississippi. During the week of August 25-28, 1980, hydrologic data on channel characteristics were collected at 15 sites on small streams draining potential lignite mining areas in east-central Mississippi. Streamflow measurements were made and water-quality samples were collected at 11 of the 15 sites. Main channel widths at the 15 sampling sites in east-central Mississippi ranged from 126 feet on Sucarnoochee Creek to 15 feet on Houston Creek. Maximum water depth ranged from 7 feet on Pawticfaw Creek and Tallahatta Creek to one-half foot on Okatibbee Creek. The maximum stream discharge measured was 56 cubic feet per second on Pawticfaw Creek. Four sites had no discharge. Specific conductance at sampling sites ranged from 115 micromhos on Ponta Creek to 26 micromhos on Sucarnoochee Creek. The dissolved-oxygen concentration was 5.7 milligrams per liter or higher at all sites. The concentration of suspended sediment was not greater than 38 milligrams per liter at any site. Concentrations of calcium, magnesium, sodium, potassium, chloride, and sulfate were less than 10 milligrams per liter in all samples, but were highest at site 10 on Ponta Creek. Bottom-material samples commonly contained iron, manganese, and zinc.

Subsurface information from eight wells drilled at the Idaho National Engineering Laboratory, southeastern Idaho

The Idaho National Engineering Laboratory (INEL) covers about 890 square miles of the eastern Snake River Plain, in southeastern Idaho. The eastern Snake River Plain is a structural basin which has been filled with thin basaltic lava flows, rhyolitic deposits, and interbedded sediments. These rocks form an extensive ground-water reservoir known as the Snake River Plain aquifer. Six wells were drilled and two existing wells were deepened at the INEL from 1969 through 1974. Interpretation of data from the drilling program confirms that the subsurface is dominated by basalt flows interbedded with layers of sediment, cinders, and silicic volcanic rocks. Water levels in the wells show cyclic seasonal fluctuations of maximum water levels in winter and minimum water levels in mid-summer. Water levels in three wells near the Big Lost River respond to changes in recharge to the Snake River Plain aquifer from the Big Lost River. Measured water levels in multiple piezometers in one well indicate increasing pressure heads with depth. A marked decline in water levels in the wells since 1977 is attributed to a lack of recharge to the Snake River Plain aquifer.

Background hydrologic information in potential lignite mining areas in Mississippi, July 1982

A water-quality sampling program was initiated in 1980 to determine background hydrologic data in potential lignite mining areas of Mississippi. This report is the third in a planned five-part series to provide data to assess future impacts of mining on small streams. The data indicates that most streams in the study area have a dissolved-solids concentration less than 100 mg/. The major ion concentrations were generally less than 10 mg/. Concentrations of arsenic, cadmium, mercury, and selenium in bottom material samples were below detectable limits. Cobalt, lead, zinc, copper, and chromium concentrations exceeded 10 micro-/g at all sites and maganese exceeded 1000 micro-/g at five sites. (USGS)
