Water budgets, including ground-water recharge and discharge for approximate equilibrium conditions, have been computed by several previous investigators; their estimates of available ground-water recharge range from about 46,000 acre-feet per year (57 cubic hectometers per year) to 100,000 acre-feet per year (123 cubic hectometers per year).</p><p>Simulation modeling of equilibrium conditions represented by 1952 water levels suggests: (1) recharge to the water-table aquifer is about 63,000 acre-feet per year (77 cubic hectometers per year); (2) a significant volume of ground water is discharged through evapotranspiration by phreatophytes growing on the valley bottomlands; (3) the major source of recharge may be from upward leakage of water from a deeper, confined reservoir; and (4) the aquifer transmissivity probably does not exceed about 12,000 feet squared per day (3,100 meters squared per day).

The gold belt coincides with a major zone of faulting, shearing, and alteration. The fault zone and most of the gold mines occur within a belt of layered metavolcanic and metavolcaniclastic rocks that is situated between a continuous belt of gneissic rocks to the west and a discontinuous belt of gneissic rocks to the east. Layered rocks are slightly to highly metamorphosed andesitic to dacitic volcanic rocks intercalated with volcaniclastic sediments. Massive volcanic rocks predominate in the southern and very northern parts of the belt whereas medium- to fine-grained sedimentary rocks and volcaniclastic rocks, in part younger than the massive volcanic rocks, predominate in the central portions. \r\n\r\nThere are five geographic groups of ancient gold mines in the belt, each of which contain deposits that are probably genetically related and are typical of that group. These deposits are hydrothermal in nature and are in or next to quartz veins, quartz breccia zones, or quartz stringer zones. A few of the deposits are spatially related to felsic dikes or small bodies of gabbro but most are in quartz veins of regional systems. \r\n\r\nIn order to facilitate evaluation of individual deposits, a model was developed to determine the potential resource of each deposit. The model was developed from historical data and utilizes geologic parameters and analyses of waste dump samples to give an optimum potential resource tonnage and grade. Although these are only estimates based upon present exposures and limited analytical data, the results indicate that the deposits in the gold belt have limited economic potential. A majority of the prospects evaluated are small deposits, each estimated to contain less than 50,000 tons of gold ore. Twelve of the prospects are estimated to contain deposits ranging from 50,000 to 400,000 tons of ore at grades ranging from 7 to 32 grams per ton (g/t).","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791519","usgsCitation":"Worl, R., 1979, The Jabal Ishmas-Wadi Tathlith gold belt, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 79-1519, ii, 112 p., 4 over-size sheets ;28 cm., https://doi.org/10.3133/ofr791519.","productDescription":"ii, 112 p., 4 over-size sheets ;28 cm.","costCenters":[],"links":[{"id":145774,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1519/report-thumb.jpg"},{"id":39624,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1519/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39625,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1519/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39626,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1519/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39627,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1519/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39628,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1519/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd171","contributors":{"authors":[{"text":"Worl, Ronald G.","contributorId":87143,"corporation":false,"usgs":true,"family":"Worl","given":"Ronald G.","affiliations":[],"preferred":false,"id":163643,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Calculated values can be displayed graphically in X-Y plots or ternary diagrams. Plotting can be done on a line printer or Calcomp plotter with either weight percent or mole percent data. Modifications in the original program give the user some control over normative calculations for each sample. The number of user-defined variables that can be created from the data has been increased from ten to fifteen. Plotting and calculations can be based on the original data, data adjusted to sum to 100 percent, or data adjusted to sum to 100 percent without water.

The movement of the tracers through the stream reach after injection is described by a one-dimensional diffusion equation. The peak concentrations of the tracers at the downstream end of the reach depend on the concentrations of the tracers in the stream at the injection site, the longitudinal dispersion coefficient, the mean water velocity, the length of the reach, and the duration of the injection period. The downstream gas concentrations also depend on the gas desorption coefficients of the reach. The concentrations of the tracer gases in the stream at the injection site depend on the flow rates of the gases through the injection diffusers, the efficiency of the gas absorption process, and the stream discharge. The concentration of dye in the stream at the injection site depends on the flow rate of the dye solution, the concentration of the dye solution, and the stream discharge. Equations for estimating the gas flow rates, the quantities of the gases, the dye concentration, and the quantity of dye together with procedures for determining the variables in these equations are presented.

Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines. A thorough understanding of the aquifer system is needed for sound management decisions. Thus, a 4-year study of the aquifer, beginning in October 1978, is included in the U.S. Geological Survey 's program of Regional Aquifer-System Analysis. The study will evaluate the aquifer 's water-supply potential, describe its water quality, and, through computer models of the ground-water flow system, provide the means to evaluate regional aquifer response to different patterns of ground-water development. This report describes the objectives, work plan, and organization of this study.

Ages of sized and magnetic fractions of zircon concentrates show variable degrees of discordance, which seem to result from a very young disturbance that produces linear arrays in the Concordia plot. Model age calculations based on a statistically and geologically reasonable lower intercept produce very consistent internal relationships. The Pan African Orogeny, considered to be responsible for loss of radiogenic argon and strontium from minerals of many rocks, does not appear to have affected the zircon data, even though uplift had exposed the rocks of the Arabian Shield at that time.</p><p>Tonalite, granodiorite, and crosscutting leuco-adamellite bodies in the southern part of the An Nimas batholith yield ages in the time range 820-760 m.y. A narrow time range of 660 to 665 million years was indicated for ages of widely separated and compositionally different intrusive bodies all to the east of the An Nimas batholith. This work suggests that the younger end of the age spectrum established from regional K-Ar and Rb-Sr measurements may be underestimated, and that magmatic activity could have been more episodic than previously assumed.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791187","usgsCitation":"Cooper, J., Stacey, J.S., Stoeser, D.B., and Fleck, R., 1979, An evaluation of the zircon method of isotopic dating in the southern Arabian Craton, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 79-1187, i, 32 p., https://doi.org/10.3133/ofr791187.","productDescription":"i, 32 p.","costCenters":[],"links":[{"id":498090,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1187/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":141560,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1187/report-thumb.jpg"}],"country":"Saudi Arabia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              33.7939453125,\n              16.678293098288513\n            ],\n            [\n              57.7001953125,\n              16.678293098288513\n            ],\n            [\n              57.7001953125,\n              32.24997445586331\n            ],\n            [\n              33.7939453125,\n              32.24997445586331\n            ],\n            [\n              33.7939453125,\n              16.678293098288513\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publicComments":"SA(IR) 257","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad8e4b07f02db684859","contributors":{"authors":[{"text":"Cooper, J.A.","contributorId":57005,"corporation":false,"usgs":true,"family":"Cooper","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":154386,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stacey, J.

This greenschist terrane is bordered on the east and west by rocks belonging to the amphibolite metamorphic facies that structurally overlie and are thrust over the Condrey Mountain Schist. The amphibolite facies is succeeded upward by metavolcanic and metasedimentary rocks belonging to the greenschist metamorphic facies. \r\n\r\nThe Condrey Mountain Schist is composed predominantly of quartz-muscovite schist and lesser amounts of actinolite-chlorite schist formed by the metamorphism of graywacke and spilitic volcanic rocks that may have belonged to the Galice Formation of Late Jurassic age. Potassium-argon age determinations of 141?4 m.y. and 155?5 m.y. obtained on these metamorphic rocks seem to be incompatible with the Late Jurassic age usually assigned the Galice. \r\n\r\nThe rocks that border the amphibolite facies are part of an extensive terrane of metavolcanic and metasedimentary rocks belonging to the western Paleozoic and Triassic belt. The metavolcanic rocks include some unmetamorphosed spilite but are mostly of the greenschist metamorphic facies composed of oligoclase (An15-20) and actinolite with subordinate amounts of chlorite and clinozoisiteepidote. The interbedded sedimentary rocks are predominantly argillite and slaty argillite, less commonly siliceous argillite and chert, and a few lenticular beds of marble. On the south, high-angle faults and a tabular granitic pluton separate the greenschist metavolcanic terrane from the amphibolite facies rocks; on the east, nonfoliated amphibolite is succeeded upward, apparently conformably, by metasedimentary rocks belonging to the greenschist metavolcanic terrane. \r\n\r\nIn the southern part of Condrey Mountain quadrangle, an outlier of a thrust plate composed of the Stuart Fork Formation overlies the metavolcanic and metasedimentary rocks. The Stuart Fork in this region is composed of siliceous phyllite and phyllitic quartzite and is believed to be the metamorphosed equivalent of rocks over which it is thrust. In the Yreka-Fort Jones area, potassium-argon determinations on mica from the blueschist facies in the Stuart Fork gave ages of approximately 220 m.y. (Late Triassic) for the age of metamorphism. \r\n\r\nRocks of the amphibolite facies structurally overlie the Condrey Mountain Schist along a moderate to steeply dipping thrust fault. The amphibolite terrane is composed of amphibolite and metasedimentary rocks in approximately equal amounts accompanied by many bodies of serpentinite and a number of gabbro and dioritic plutons. Most of the amphibolite is foliated, but some is nonfoliated; the nonfoliated amphibolite has an amphibolite mineralogy and commonly a relict volcanic rock texture. The nonfoliated amphibolite occurs on the southern and eastern borders of the amphibolite terrane between the areas offoliated amphibolite and the overly ing metavolcanic and metasedimentary rocks. Hornblende and plagioclase (An30-35) are the characteristic minerals, indicating that the rocks are of the almandine-amphibolite metamorphic facies. The metasedimentary rocks interbedded with the amphibolites include siliceous schist and phyllite, minor quartzite, and subordinate amounts of marble. Potassium-argon age dates obtained on hornblende from foliated amphibolite yield ages of 146?4 and 148? 4 m.y., suggesting a Late Jurassic metamorphic episode. \r\n\r\nMafic and ultramafic rocks are widespread in the amphibolite terrane but are almost entirely absent from the area of greenschist facies metavolcanic and metasedimentary rocks. The ultramafic rocks, predominantly serpentinite, occur as a few large bodies and many small tabular concordant bodies interleaved with the foliated rocks. The ultramafic rocks include harzburgite and d1lIlite and their serpentinized equivalents. In the Condrey Mountain quadrangle, probably more t","language":"ENGLISH","publisher":"U.S. Govt. Print.

This study was done in cooperation with the Arkansas Department of Pollution Control and Ecology to fulfill the requirements of section 208 of Public Law 92-500. An assessment of the general water quality was made, the causes of stream-dissolved-oxygen reductions were determined, and the occurrence of pesticides and trace metals in the basin was documented. A steady-state, segmented, dissolved-oxygen model was calibrated and used to project simulated dissolved-oxygen profiles.</p><p>Pesticides are used extensively in the basin and their occurrence in streams throughout the basin is documented. Concentrations of DDT from the river were as high as 110 micrograms per kilogram in streambed material, whereas 1,600 micrograms per kilogram of DDE and 530 micrograms per kilogram of DDD were found in bottom-feeding fish.

Two aspects of land utilization were studied for this report: (1) the seismic and geotechnical properties of a landslide and (2) the seismic, magnetic, and geotechnical properties of clinker deposits. \r\n\r\n(1) The landslide seismic survey revealed two layers in the slide area. The upper (low-velocity) layer is a relatively weak mantle of colluvium and unconsolidated and weathered bedrock that ranges in thickness from 3.0 to 7.5 m and has an average seismic velocity of about 390 m/s. It overlies high-velocity, relatively strong sedimentary bedrock that has velocities greater than about 1330 m/s. The low-velocity layer is also present at the other eight seismic refraction sites in the basin; a similar layer has also been \r\nreported in the Soviet Union in a landslide area over similar bedrock. The buried contact of the low- and high-velocity layers is relatively smooth and is nearly parallel with the restored topographic surface. There is no indication that any of the high-velocity layer (bedrock) has been displaced or removed. \r\n\r\nThe seismic data also show that the shear modulus of the low-velocity layer is only about one-tenth that of the high-velocity layer and the shear strength (at failure) is only about one-thirtieth. Much of the slide failure is clearly in the shear mode, and failure is, therefore, concluded to be confined to the low-velocity layer. The major immediate factor contributing to landslide failure is apparently the addition of moisture to the low-velocity layer. \r\n\r\nThe study implies that the low-velocity layer can be defined over some of the basin by seismic surveys and that they can help predict or delineate potential slides. Preventative actions that could then be taken include avoidance, dewatering, prevention of saturation, buttressing the toe, and unloading the head. The low-velocity layer is usually less than about 5 m thick and may be excavated by dozing, whereas the bedrock must be blasted. Thus, it would seem economically feasible to underpin a structure to nonweathered bedrock or, perhaps, to remove the low-velocity layer prior to construction. \r\n\r\n(2) Many coal beds in the Powder River Basin have burned along their outcrops, and the resulting intense heat has baked and fused the overlying clastic (sedimentary) rocks into clinkers. The clinkers are very magnetic and a buried edge of a single layer of burn can easily be located by magnetic prospecting methods. Location of the edge is very important in estimating unburned coal deposits, locating clinker quarries, and planning drilling of seismic reflection lines.\r\n\r\nThe clinkers are very porous and highly fractured,-and seismic and geotechnical tests show that they have relatively low strength and competency. Many of the laboratory tests, however, are inherently biased because the clinkers are so highly fractured that only competent samples are selected. The laboratory tests, for example, show that clinkers must be loosened by heavy ripping tractors or blasting, whereas the field data and practical experience indicate that clinkers may be mined with light equipment. \r\n\r\nHeavy structures such as coal silos and bridge abutments may have to be sited on clinkers. However, differential settlement may occur, with failure in the shear mode, because chimneys of relatively greater strength occur among the weaker clinkers. Preliminary data indicate that the chimneys may be located by magnetic or possibly seismic surveys. Special foundation-preparation techniques could be used or, perhaps, the chimneys could be avoided altogether at a construction site.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79952","usgsCitation":"Miller, C., 1979, Seismic, magnetic, and geotechnical properties of a landslide and clinker deposits, Powder River basin, Wyoming and Montana: U.S. Geological Survey Open-File Report 79-952, iv, 47 p.:ill., maps ;28 cm., https://doi.org/10.3133/ofr79952.","productDescription":"iv, 47 p.:ill., maps ;28 cm.","costCenters":[],"links":[{"id":143460,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0952/report-thumb.jpg"},{"id":38176,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0952/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685c1b","contributors":{"authors":[{"text":"Miller, C.H.","contributorId":19148,"corporation":false,"usgs":true,"family":"Miller","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":161200,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Measurements of thermal gradient in the upper few tens of meters generally are sufficient to outline the major anomalies, but it is always desirable to combine these gradients with reliable estimates of thermal conductivity to provide data on the energy flux and to constrain models for the heat sources responsible for the observed, near-surface thermal anomalies. The major problems associated with heat-flow measurements in the geothermal exploration mode are concerned with the economics of casing and/or grouting holes, the repeated site visits necessary to obtain equilibrium temperature values, the possible legal liability associated with the disturbance of underground aquifers, the surface hazards presented by pipes protruding from the ground, and the security problems associated with leaving cased holes open for periods of weeks to months. \r\n\r\nWe have developed a technique which provides reliable 'real-time' determinations of temperature, thermal conductivity, and hence, of heat flow during the drilling operation in unconsolidated sediments. A combined temperature, gradient, and thermal conductivity experiment can be carried out, by driving a thin probe through the bit about 1.5 meters into the formation in the time that would otherwise be required for a coring trip. Two or three such experiments over the depth range of, say, 50 to 150 meters provide a high-quality heat-flow determination at costs comparable to those associated with a standard cased 'gradient hole' to comparable depths. The hole can be backfilled and abandoned upon cessation of drilling, thereby eliminating the need for casing, grouting, or repeated site visits.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79593","usgsCitation":"Sass, J., Kennelly, J., Wendt, W., Moses, T., and Ziagos, J., 1979, In situ determination of heat flow in unconsolidated sediments: U.S. Geological Survey Open-File Report 79-593, v, 71 p., 4 sheets :ill., map ;28 cm., https://doi.org/10.3133/ofr79593.","productDescription":"v, 71 p., 4 sheets :ill., map ;28 cm.","costCenters":[],"links":[{"id":160335,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0593/report-thumb.jpg"},{"id":59576,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0593/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fae4b07f02db5f41ce","contributors":{"authors":[{"text":"Sass, J.H.","contributorId":70749,"corporation":false,"usgs":true,"family":"Sass","given":"J.H.","email":"","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":204162,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kennelly, J.P.","contributorId":16051,"corporation":false,"usgs":true,"family":"Kennelly","given":"J.P.","affiliations":[],"preferred":false,"id":204159,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wendt, W.E.","contributorId":60248,"corporation":false,"usgs":true,"family":"Wendt","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":204161,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moses, T.H.","contributorId":24344,"corporation":false,"usgs":true,"family":"Moses","given":"T.H.","email":"","affiliations":[],"preferred":false,"id":204160,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ziagos, J.P.","contributorId":77931,"corporation":false,"usgs":true,"family":"Ziagos","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":204163,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Although the entire central section of the San Andreas fault is characterized by moderate seismicity and aseismic creep, Dry Lake Valley has particularly shallow earthquakes as well as a fairly high creep rate (18-20 mm/year, S. Schultz, pers. comm.). Fig. 2 is a longitudinal section along the San Andreas fault showing high precision locations of magnitude one or greater earthquakes that occurred in 1973-1975 (from W. Ellsworth, per. comm.). The depth accuracy of the earthquakes shown is about <span>±</span> 0.5 km, and it is obvious from Figure 2 that Dry Lake Valley earthquakes are extremely shallow.</p><p>As shown in Figure 1 the general geology of the central section of the San Andreas fault consists of Tertiary to Jurassic sedimentary and volcanic rocks overlying Cretaceous age Gabilan granite of the Salinian Block on the west side of the fault and Cretaceous-Jurassic sedimentary assemblages of the Franciscan Complex to the east of the fault. Dibblee (1979) summarizes the geology along the central San Andreas fault. At the Dry Lake Valley site as much as 2 km of Pliocene-Miocene marine sediments (Etchegoin and Santa Margarita formation) overlie Franciscan rocks on the northeast side of the San Andreas fault. On the southwestern side of the fault, 1-2 km of Pliocene-Miocene valley sediments and granitic conglomerate overlies the Gabilan granite.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791206","usgsCitation":"Roller, J.C., Zoback, M.D., Raleigh, C., and Liechti, R., 1979, Preliminary report on drilling in and near the San Andreas fault zone, California; Dry Lake Valley No. 1: U.S. Geological Survey Open-File Report 79-1206, 9 p., https://doi.org/10.3133/ofr791206.","productDescription":"9 p.","costCenters":[],"links":[{"id":424208,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1206/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":141582,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1206/report-thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Dry Lake Valley, San Andreas fault zone","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.1304821047622,\n              36.76699348900142\n            ],\n            [\n              -121.1304821047622,\n              35.846256286535905\n            ],\n            [\n              -119.449573901637,\n              35.846256286535905\n            ],\n            [\n              -119.449573901637,\n              36.76699348900142\n            ],\n            [\n              -121.1304821047622,\n              36.76699348900142\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cb23","contributors":{"authors":[{"text":"Roller, John C.","contributorId":60642,"corporation":false,"usgs":true,"family":"Roller","given":"John","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":155648,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zoback, Mark D.","contributorId":80275,"corporation":false,"usgs":true,"family":"Zoback","given":"Mark","middleInitial":"D.","affiliations":[],"preferred":false,"id":155650,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Raleigh, C.B.","contributorId":40219,"corporation":false,"usgs":true,"family":"Raleigh","given":"C.B.","email":"","affiliations":[],"preferred":false,"id":155647,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Liechti, R.P.","contributorId":67510,"corporation":false,"usgs":true,"family":"Liechti","given":"R.P.","email":"","affiliations":[],"preferred":false,"id":155649,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native wood casing with steel during the 20th century increased corrosion problems and, in what is called the New Valley Project, led to an intense search for causes and corrective treatments. This revealed that extreme corrosiveness results from combined effects of relatively acidic waters with significant concentrations of destructive sulfide ion; unfavorable ratios of sulfate and chloride to less aggressive ions; mineral equilibria and electrode potential which hinder formation of protective films; relative high chemical reaction rates because of abnormal temperatures, and high surface velocities related to well design. \r\n\r\nThere is general agreement among investigators that conventional corrosion control methods such as coating metal surfaces, chemical treatment of the water, and electrolytic protection with impressed current and sacrificial electrodes are ineffective or impracticable for wells in the Western Desert's New Valley. Thus, control must be sought through the use of materials more resistant to corrosion than plain carbon steel wherever well screens and casings are necessary. Of the alternatives considered, stainless steel appears to. be the most promising where high strength and long-term services are required and the alloy's relatively high cost is acceptable. Epoxy resin-bonded fiberglass and wood appear to be practicable, relatively inexpensive alternatives for installations which do. not exceed their strength limitations. Other materials such as high strength aluminum and Monel Metal have shown sufficient promise to. merit their consideration in particular locations and uses. The limited experience with pumping in these desert wells leaves uncertainties concerning the durability of conventional pump designs. \r\n\r\nEgypt's New Valley Project provides an excellent opportunity for continuing study of the corrosion problems that concern ground-water developers in many parts of the world.","language":"ENGLISH","publisher":"U.S. Govt.
