An equation derived for the vertical gravity field due to a body with polygonal cross section and finite strike length. The equations consists of the 2-dimensional equation of Talwani, Worzel, and Landisman (1959), with the addition of end corrections. Equations for the magnetic field due to a similar body were derived by Shuey and Pasquale (1973). They coined the term \"2 1/2-dimensional\" to describe the geometry.
\nIf the geometry of the causative body or bodies is specified, the 2 1/2-dimensional equations can be combined with observation of the gravity and magnetic anomaly fields to make linear least squares solutions for density and susceptibility or remanent magnetization.
\nA computer program is presented which performs, for one or more bodies, along a profile perpendicular to strike, both forward calculations for the magnetic and gravity anomaly fields and independent gravity and magnetic inverse calculations for density and susceptibility or remanent magnetization.

Channel dimensions were measured at 59 sites in Lucerne Valley. Dranage area-discharge relations developed from channel-geometry data for sites nearby were used to estimate the discharge at 12 additional sites where channel geometry could not be measured. In order to compute the total volume discharge into the playa, the peak discharges were converted to volumes. From the Apple Valley report (Busby, 1975) the equation formulated from the relation between peak discharge and flood volume for the deserts of California was used to compute the flood volumes for routing into Lucerne Lake.

The Winona-Tallahatta aquifer, which contains freshwater having less than 1,000 mg/liter of dissolved solids in about 25 percent of the State occurs in northwestern and central Mississippi. The water-bearing zones extend into Tennessee and become part of the Memphis aquifer. In Arkansas and Louisiana the aquifer is in the Cane River Formation. The Tallahatta Formation which is the basal unit of the Claiborne Group includes, in ascending order, the Meridian Sand, Basic City Shale, and Neshoba Sand Members. The Winona-Tallahatta aquifer is the source of water for only a few large water users, but is the source of water for hundreds of small-yield domestic and stock wells less than 200 feet deep.

The high-grade metasedimentary rocks give a whole-rock Rb-Sr age of 735 m.y. This late Precambrian age is believed to be the time of metamorphism. Orthogneisses, intrusive into the metasedimentary rocks, are probably also Precambrian in age; but many samples have had their ages disturbed by Cretaceous intrusions and thrusting.
Samples of Precambrian metagabbro are low in radioelements (U, Th, and K) typical of basalitc rocks. The Precambrian metasedimentary rocks have normal radioelement concentrations, but both the Precambrian orthogneisses and the Cretaceous granitic rocks are unusually rich in thorium.

The recharge water is untreated and analyses show it to be chemically and physically compatible with the water in the Floridan aquifer. The temperatures of the recharging and receiving waters were identical, 23 deg C. The transfer of water from the lower sand aquifer to the Floridan aquifer caused only a small buildup of artesian pressure in the Floridan aquifer but it lowered the artesian head 4 feet in the lower sand aquifer near the well which supplied the recharge water. Water levels in the upper sand aquifer were not affected, probably because of the low permeability of an intervening hardpan layer. However, after six auger holes back-filled with sand connected the two sand aquifers on April 5, 1972, a rise of water levels in the lower sand aquifer was noted. The principal chemical and physical effects on the water in the Floridan aquifer were a general improvement in chemical quality and an increase in color. The color may decrease as more water moves through the sand aquifer and the material responsible for the high color is removed by flushing.

In Arizona the largest amount of precipitation was in the north rim area of eastern Grand Canyon, where about 14 inches was measured. The largest flows occurred along Bright Angel Creek and the MilK Creek-Dragon Creek part of the Crystal Creek drainage basin. The maximum effects of the flood were along Milk Creek-Dragon Creek, where a mudflow caused extensive channel modification. Floods that occurred in the Bright Angel and Crystal Creek basins have a recurrence interval of only once in several centuries. The streamflow that resulted from the storm on the Kaibab Plateau caused considerable local scouring and deepening of channels, including some renewed arroyo cutting. The most catastrophic effects of the 1966 floods were caused by two mudflows that extended from the edge of the Kaibab Plateau along Dragon Creek in the Crystal Creek basin and Lava Creek in the Chuar Creek basin to the Colorado River. More than 10 other large mudflows occurred in Nankoweap, Kwagunt, Crystal, and Shinumo Creek basins. About 80 large debris slides left conspicuous scars in the amphitheaters at the heads of the side gorges, and at least 10 small slides occurred on the Kaibab Plateau.

The open pits filled with water and pond-type ecosystems developed. Light was transmitted to greater depths within two control ponds located outside the mine area. The lower light transmittance in the ponds within the mined area probably was due, in part, to the greater number of phytoplankton cells. Also, unconsolidated soil material within the mine area was observed to slough off the pond banks, which could add to the concentration of suspended sediments. Dissolved oxygen concentrations were lower in the ponds within the mined area. Most of the major ions (calcium, magnesium, sulfate, and sodium) were present in greater concentrations in the ponds within the mined area. Higher concentrations of bicarbonate and total hardness were in the water within the mined area. Biological communities were less diverse and chemical concentrations fluctuated more in the mined area than in the ponds outside the mined area.

The initial injection rate of 400 gpm decreased to 70 gpm during test 3. The specific capacity of the well decreased also, from 15.4 to 0.93 gpm. Current-meter surveys indicated uniform reduction in hydraulic conductivity of all contributing zones in the aquifer. Hydraulic and chemical data indicate this was caused by dispersion of the interstitial clay upon introduction of the calcium bicarbonate water into the sodium chloride bearing sand aquifer. The clay dispersion also caused particulate rearrangement and clogging of well screen. A pre-flush of 0.2 N calcium chloride solution injected in front of the fresh water at the start of test 4 stabilized the clay. However, it did not reverse the particulate clogging that permanently reduced permeability and caused sanding during redevelopment. Clogging can be prevented by stabilization of the clay using commercially available trivalent aluminum compounds. Test 1 and test 2 showed that 85 percent of the water injected can be recovered, and the water meets U.S. Public Health Standards. Storage of fresh water in a brackish-water aquifer appears feasible provided proper control measures are used. (Woodard-USGS)","language":"ENGLISH","publisher":"U.S. Govt. Print.

This circular and a companion folio of maps represent results of integrated field and laboratory studies in the disciplines of geology, geophysics, geochemistry, and satellite imagery that are designed to provide a modern mineral resource assessment of the quadrangle. The maps are accompanied by descriptive texts, explanatory material, pertinent references, and by a few auxiliary tables and diagrams. This circular provides background information for the mineral resource assessment and integrates the component maps. It also includes a master list of references (see 'Bibliography') relevant to the geology and mineral deposits of the quadrangle.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nDept. of the Interior, Geological Survey, Branch of Distribution,","doi":"10.3133/cir739","usgsCitation":"MacKevett, E., Albert, N.R., Barnes, D., Case, J.E., Robinson, K., and Singer, D., 1977, The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and mineral resource maps of the McCarthy Quadrangle, Alaska: U.S. Geological Survey Circular 739, iii, 23 p. :maps ;26 cm. , https://doi.org/10.3133/cir739.","productDescription":"iii, 23 p. :maps ;26 cm.
