'Caliche' includes various carbonates such as calcic soils and products of groundwater cementation. The term 'caliche' is generally avoided in this report in favor of such terms as calcrete, calcic soils, and pervasively cemented deposits. \r\n\r\nCriteria for the recognition of various types of calcrete of diverse origins include field relations and laboratory data. Calcic soils provide a comprehensive set of characteristics that aid in their recognition in the field. These characteristics include a distinctive morphology that is zoned horizontally and can frequently be traced over tens to hundreds of square kilometers. \r\n\r\nThe major process in the formation of pedogenic calcrete and calic soils is the leaching of calcium carbonate from upper soil horizons by downward percolating soil solutions and reprecipitation of the carbonate in alluvial horizons near the base of the soil profile. The formation of pedogenic calcrete involves many factors including climate, source of carbonate, and tectonic stability of the geomorphic surface on which the calcrete is deposited. Most of the carbonate in pedogenic calcrete is probably derived from windblown sand, dust, and rain. \r\n\r\nCalcic soils and pedogenic calcretes follow a six-stage sequence morphologic development and is based on a classification devised by Gile, Peterson and Grossman in 1966. The .six morphologic stages of carbonate deposition in soils are related to the relative age of the soil and are as follows: \r\n\r\nI. The first or youngest stage includes filamentous or faint coatings of carbonate on detrital grains. \r\nII. The second stage includes pebble coatings which are continuous; firm carbonate nodules are few to common. \r\nIII. The third stage includes coalesced nodules which occur in a friable or disseminated carbonate matrix. \r\nIV. The fourth stage includes platy, firmly cemented matrix which engulfs nodules; horizon is plugged to downward moving solutions. \r\nV. The fifth stage includes soils which are platy to tabular, dense, strongly cemented. A well-developed laminar layer occurs on the upper surface. \r\nVI. The sixth and most advanced stage is massive, multilaminar, and strongly cemented calcrete with abundant pisoliths, the upper surface of which may be brecciated. Pisoliths may indicate many generations of brecciation and reformation. \r\n\r\nIn general calcic soils include stages I through III and are friable to moderately indurated; whereas pedogenic calcretes include stages IV through VI and are dense and strongly indurated. In a single pedon the morphologic stage of carbonate deposition decreases downward in the profile. The stage of development may be used in local regions for correlation and determination of relative ages of soils and geomorphic surfaces. Some structures observed in pedogenic calcretes may be present in other types of calcrete but the horizontal zonation typical of deposits of soil processes is absent. Laminar structure in particular is not restricted to pedogenic deposits and is common in many varieties of calcrete. \r\n\r\nVery little chemical change occurs in the noncalcareous nonclayey fractions of calcretes with age; but clay minerals within calcretes undergo a complex history of authigenesis. There is a depletion of magnesium in the calcareous portion and an enrichment of magnesium in the clayey portion of a calcrete with age. In keeping with this relationship, montmorillonite, or mixed layer montmorillonite-illite, is common in younger calcretes; whereas the high magnesium-silicate clays, sepiolite and palygorskite, are common in older calcretes. This indicates that the magnesium depleted from the carbonate is redistributed authigenically in clay minerals. \r\n\r\nThe mobility of carbonate introduces many problems in attempts to date calcretes directly.

Only the unconfined aquifer was modeled, using several simplifying assumptions concerning hydrologic conditions in the ground-water basin.

Testing of the model indicated that simulated water levels were especially sensitive to tansmissivity, storage coefficient, irrigation return, and riverbed hydraulic conductivity; amond the parameters that affected water levels least were the vertical hydraulic conductivity and specific storage of the confining bed, the so-called E-clay.

The analyses indicate a general trend of aggradation in the lower part of the floodway with a consequent trend toward increasing the inundated area, especially at higher flood flows.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7714","usgsCitation":"Jennings, M.E., and Land, L.F., 1977, Simulation studies of flow and sediment transport using a mathematical model, Atchafalaya River Basin, Louisiana: U.S. Geological Survey Water-Resources Investigations Report 77-14, vi, 55 p., https://doi.org/10.3133/wri7714.","productDescription":"vi, 55 p.","costCenters":[],"links":[{"id":359497,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1977/0014/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":158775,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1977/0014/report-thumb.jpg"}],"country":"United States","state":"Louisiana","otherGeospatial":"Atchafalaya River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.91986083984375,\n              29.310351371763023\n            ],\n            [\n              -91.14532470703125,\n              29.310351371763023\n            ],\n            [\n              -91.14532470703125,\n              31.027047769854388\n            ],\n            [\n              -91.91986083984375,\n              31.027047769854388\n            ],\n            [\n              -91.91986083984375,\n              29.310351371763023\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68a5f6","contributors":{"authors":[{"text":"Jennings, Marshall E.","contributorId":55813,"corporation":false,"usgs":true,"family":"Jennings","given":"Marshall","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":198848,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Land, Larry F.","contributorId":60612,"corporation":false,"usgs":true,"family":"Land","given":"Larry","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":198847,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Long-term average annual recharge to the aquifer from streams and precipitation is estimated to total about 24,270 acre-feet. Pumpage from public-supply and irrigation wells is estimated to have totaled about 48,000 acre-feet from 1938 through 1972. This pumpage did not cause any noticeable decrease in natural discharge and it is assumed there has been no significant change in ground-water storage. Pumpage is estimated to total about 39,500 acre-feet for the 3-year period 1973 through 1975. A digital model was developed to simulate the ground-water system in the Arikaree Formation. The model can be used to indicate the general effect of applying hydraulic stresses to the aquifer.

They are flooding, landsliding, and subsidence over underground mines. In 1973, information was most complete relative to flooding and least complete relative to landsliding. </p><p>Accordingly, in July 1973, the U.S. Geological Survey (USGS) and The Appalachian Regional Commission (ARC) entered into an agreement by which the USGS undertook studies chiefly aimed at increasing knowledge of landsliding and mine subsidence relative to land use, but having other ramifications as well, as part of a larger ARC 'Land-use and physical-resource analysis' (LUPRA) program. The chief geographic focus was Allegheny County, but adjacent areas were included in some investigations. </p><p>Resulting products, exclusive of this report, are: </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">1. Forty-three provisional maps of landslide, distribution and susceptibility and of land modified by man in Allegheny County, 1:24,000 scale, 7½ -minute quadrangle format, released to open files. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">2. Four USGS Miscellaneous Field Studies (MF) maps of Allegheny County showing (a) bedrock, MF685A; (b) susceptibility to landsliding, MF-685B ; (c) coal-mining features, MF-685C; and (d) zones that can be affected by flooding, landsliding and undermining, MF-685D; all at the scale of 1:50,000. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">3. Two MF maps showing coal-mining activity and related information and sites of recorded mine-subsidence events, and one MF map classifying land surface by relative potentiality of mine subsidence, in Allegheny, Washington, and Westmoreland Counties, Pa., at a scale of 1:125,000--MF-693A through MF-693C. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">4.

Five MF maps, largely in chart form, describing interaction of the shallow ground-water regime with mining-related problems, landsliding, heavy storm precipitation, and other features and processes, largely in Allegheny County--MF-641A through MF-641E. </p><p>Map products are directly applicable to general classification of land for susceptibility to landsliding and mine subsidence and, to a lesser extent, flooding and engineering characteristics. The hydrogeologic charts enable greater understanding of environmental effects of ground water. All products are guides to expected conditions, but none are substitutes for detailed investigations of specific sites by competent technical personnel on the ground. </p><p>Specific results and findings are: </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">1. Knowledge of .susceptibility to landsliding in Allegheny County now is adequate for application to countywide land-use planning. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">2. About 110 mi<sup>2</sup> (285. km<sup>2)</sup>, or 15 percent, of the county has some significant degree of susceptibility to landsliding. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">3. Although a general classification of land in Allegheny, Washington, and Westmoreland Counties relative to mine-subsidence incidents was prepared, data are wholly inadequate for even moderately precise prediction of subsidence events over previously mined-out areas; the accumulation of adequate data might not repay the effort in terms of damage prevention. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">4. Commonwealth-of-Pennsylvania regulations, have been very successful in limiting mine-subsidence damage over areas mined after 1966. </p><p style=\"padding-left: 40px;\" data-mce-style=\"padding-left: 40px;\">5. Undermining and consequent subsidence may have affected the ground-water regime more widely than heretofore believed. </p><p>Except for the earth-disturbance inventory that resulted in the maps of susceptibility to landsliding and man-modified land, methods used in the studies largely were conventional. The inventory and ensuing analysis combined aerial photographic interpretation with field work and incorporation of existing data. The method worked very well for the purposes of defining distribution of landslides and areas having different susceptibilities to landsliding. However, if susceptibility to landsliding alone had been the goal, this could have been determined adequately by using photographs at smaller scales and appreciably less expenditure of effort per unit of ground area.</p>","language":"English","publisher":"U.S. Government Printing Office","doi":"10.3133/cir747","usgsCitation":"Briggs, R.P., 1977, Environmental geology, Allegheny County and vicinity,

The principal source of ground water in the basin is a shallow unconfined aquifer in the valley alluvium. Continuous pumping of the shallow aquifer has induced the flow of saltwater and has caused the chloride concentration to increase from about 30 to 540 milligrams per liter in the lower part of the valley. A study from January 1971 to December 1974 indicated that the hydraulic conductivities of the aquifer materials, in the basin, are less than 1 foot per day for the metavolcanic and igneous rocks. Estimated conductivities range from 10 to 100 feet per day for the alluvium. The average transmissivity of the alluvial aquifer is estimated to be 4,000 feet squared per day and the average specific capacity is 20 gallons per minute per foot of drawdown. In December 1974, the alluvial aquifer contained an estimated 10 ,000 acre-feet of water in recoverable storage. The data suggest that water supplies to meet future needs could be supplemented by the construction of surface-water-control structures and additional wells. Analysis of a digital simulation model suggests that wells be located in the upper reaches of the alluvial aquifer where a sustained yield of 3,000 gallons per minute could be obtained.

Test drilling based on conceptual models of ground-water occurrence in carbonate-rock aquifers indicate that multimillion-gallon-per-day supplies could be developed from strategically located production wells in the Shiloh and Overall Creek localities. The Shiloh locality which encompasses an elongated synclinal depression in the bedrock has the potential to supply 5 to 8 million gallons per day. The Overall Creek locality which straddles a joint-oriented lineament has the potential to supply 3 to 6 million gallons per day. Some local springs could be used as a supplemental source of potable water, but storage facilities would be needed to offset poorly sustained flows during dry periods. An exception is Fox Camp Spring which appears to be a natural well. The quality of ground water in the Murfreesboro area is typically hard, moderately mineralized and moderately to highly alkaline.

The distribution of the thermal areas below the summit of Mt. Hood, shown on planimetrically corrected maps at 1:12,000, suggests structural control by a fracture system and brecciated zone peripheral to a hornblende-dacite plug dome (Crater Rock), and by a concentric fracture system that may have been associated with development of the present crater. The extent and inferred temperature of the thermal areas permits a preliminary estimate of a heat discharge of 10 megawatts, by analogy with similar fumarole and thermal fields of Mt. Baker, Washington. This figure includes a heat loss of 4 megawatts (MW) via conduction, diffusion, evaporation, and radiation to the atmosphere, and a somewhat less certain loss of 6MW via fumarolic mass transfer of vapor and advective heat loss from runoff and ice melt. The first part of the estimate is based on two-point models for differential radiant exitance and differential flux via conduction, diffusion, evaporation, and radiation from heat balance of the ground surface. Alternate methods for estimating volcanogenic geothermal flux that assume a quasi-steady state heat flow also yield estimates in the 5-11 MW range. Heat loss equivalent to cooling of the dacite plug dome is judged to be insufficient to account for the heat flux at the fumarole fields.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77599","usgsCitation":"Friedman, J.D., and Frank, D., 1977, Structural and heat-flow implications of infrared anomalies at Mt.

Seepage investigations showed that during periods of base flow, the surface-water regime cannot be predicted on the basis of flow-duration figures alone. The investigations also indicate that the streambeds are permeable for extended reaches throughout the areas studied. Inconsistent data on gain or loss for a given reach are assumed to be indicative of the changes in rate of ground-water recharge or discharge. Analysis of surface-water quality since 1972 showed high nitrate (as NO3) concentrations (4 to 18 mg/liter) in the Cortland area and in Factory Brook. The nitrate source is probably from human activities.

The metamorphic rocks include amphibolite-facies orthogneiss and paragneiss, greenschist-facies fine-grained siliceous and graphitic metasediments, and a variety of carbonate rocks. Lithologic units within the metamorphic terrane trend generally north-northeast and dip moderately toward the southeast. Thrust faults locally juxtapose lithologic units in the metamorphic assemblage, and normal faults displace both the metamorphic rocks and some parts of the granite stock. The gneisses and graphitic metasediments are believed to be late Precambrian in age, but the carbonate rocks are in part Paleozoic. Dating by the potassium-argon method indicates that the granite stock is Late Cretaceous. \r\n\r\nThe stock has sharp discordant contacts, beyond which is a well-developed thermal aureole with rocks of hornblende hornfels facies. The average mode of the granite is 29 percent plagioclase, 31 percent quartz, 36 percent K-feldspar, and 4 percent biotite. Accessory minerals include apatite, magnetite, sphene, allanite, and zircon. Late-stage or deuteric minerals include muscovite, fluorite, tourmaline, quartz, and albite. \r\n\r\nThe stock is a zoned complex containing rocks with several textural facies that are present in four partly concentric zones. Zone 1 is a discontinuous border unit, containing fine- to coarse-grained biotite granite, that grades inward into zone 2. Zone 2 consists of porphyritic biotite granite with oriented phenocrysts of pinkish-gray microcline in a coarse-grained equigranular groundmass of plagioclase, quartz, and biotite. It is in sharp, concordant to discordant contact with rocks of zone 3. Zone 3 consists of seriate-textured biotite granite that has been intruded by bodies of porphyritic biotite granite containing phenocrysts of plagioclase, K-feldspar, quartz, and biotite in an aplitic groundmass. Flow structures, pegmatite and aplite segregations, and miarolitic cavities are common in the seriate-textured granite. Zone 4, which forms the central part of the complex, consists of fine- to medium-grained biotite granite and locally developed leucogranite. Small miarolitic cavities are common within it. \r\n\r\nEight textural facies have been defined within the complex, and mineralogic, petrographic, modal, and chemical variations are broadly systematic within the facies sequence. Study of these variations shows that the gradational facies of zones l and 2 systematically shift toward more mafic compositions inward within the complex. Seriate-textured rocks of zone 3 are similar in composition to those of zone 2, but porphyritic rocks of zone 3 and rocks of zone 4 mark shifts to more felsic compositions. These late-crystallizing felsic rocks are products of an interior residual magma system. This system was enriched in water and certain trace elements including tin, lithium, niobium, lead, and zinc. The complex as a whole has higher concentrations of these elements than many other granites. The nature of this geochemical specialization is particularly well demonstrated by the trace-element composition of biotite.\r\n\r\nThe crystallization history of the pluton was complex. The available data suggest that this history could have included: (1) chilling and metasomatic alteration adjacent to the contact, (2) in-situ crystallization in several marginal facies accompanied by some transfer of residual constituents toward interior parts of the pluton, (3) slight upward displacement of magma that was subjacent to the crystallized walls, accompanied by disequilibrium crystallization and local vapor saturation, (4) upward displacement of part of the residual water-rich interior magma, accompanied by rapid loss of a separated vapor phase, and (5) displacement of the margins of the pluton by normal faults, accompanied by loss of an exsolved vapor phase from th","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr7735","usgsCitation":"Hudson, T., 1977, Genesis of a zoned granite stock, Seward Peninsula, Alaska: U.S. Geological Survey Open-File Report 77-35, xv, 188 p. :ill., maps (1 fold. in pocket) ; scale 1:31,680; 28 cm., https://doi.org/10.3133/ofr7735.","productDescription":"xv, 188 p. :ill., maps (1 fold. in pocket) ; scale 1:31,680; 28 cm.","costCenters":[],"links":[{"id":151857,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0035/report-thumb.jpg"},{"id":48947,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0035/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":48948,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0035/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"31680","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6aebcf","contributors":{"authors":[{"text":"Hudson, Travis","contributorId":90282,"corporation":false,"usgs":true,"family":"Hudson","given":"Travis","affiliations":[],"preferred":false,"id":180978,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Surface morphology and internal characteristics of glacial and glaciofluvial erosional and depositional features were examined and mapped in detail in the Kent and Ellsworth, Connecticut, USGS 7? minute quadrangles, and by reconnaissance in the surrounding quadrangles. This study contributes to the expanding detailed knowledge of glaciation and geomorphology in western New England and eastern New York state. \r\n\r\nIce along the lateral east margin of the southward-waxing, Wisconsin-age, Hudson-Champlain Valley ice lobe successively overran ridges trending northeast-to-southwest. Late Wisconsin ice flow was consistently toward the southeast in the study area. Glacial erosion on the upland surfaces was weak, and several early or pre-Wisconsin meltwater channels persist, which evidence little late Wisconsin glacial or glaciofluvial modification. Deeply weathered rock has been locally preserved beneath unweathered till. \r\n\r\nTill deposits are generally thin, averaging from 10 to 15 feet in thickness, but till deposits exceeding 200 feet in thickness have been observed. Direct evidence for two or more cycles of till deposition is lacking, although multiple glaciations can be inferred from drainage derangement of the Housatonic River and from anomalies in configuration of old, upland melt-water channels which were re-occupied and eroded by melt water during subsequent deglaciations. \r\n\r\nThe orientation of ridges and the local terrain relief exerted minor control on ice flow during waxing phases of glaciation. Local relief and ridges which were oriented transverse to ice flow became the dominant control factors for ice flow during late phases of deglaciation and ultimately initiated marginal stagnation zones. \r\n\r\nLate Wisconsin deglaciation evolved in three stages. First, the active ice margin receded rapidly northwestward across, and almost transverse to, the upland ridge crests in response to factors of both backwasting and downwasting. Second, local terrain relief restricted active ice flow, initiated stagnation, diverted melt-water flow and controlled deposition of small active ice-marginal deposits on the northwest slopes of ridges. Third, melting and thinning of stagnant ice tongues in valleys with ice surfaces which were low gradient and southward-sloping caused rapid northward recession of the stagnant ice margin. \r\n\r\nSequences of related outwash deposits have been correlated with inferred ice-marginal, recessional positions. In this region, the zone of stagnant ice distal to active ice ranged from 6 to 15 miles in average width. \r\n\r\nLacustrine sediments accumulated as stagnant ice blocks melted in isolated basins and other depressions where through-flowing melt-water drainage was restricted or absent. The paucity of ice-contact and outwash deposits in the isolated basins indicates that little entrained debris was present in the stagnant ice. Prograding outwash along the Housatonic River and other major drainage routes infilled glacially overdeepened \r\nunderlying lacustrine sediments sand and gravel. rock basins and buried beneath upward-coarsening \r\n\r\nUpland bogs, which have developed postglacially, contain as much as 22 feet of organic material mixed with silt and clay. An age of 12,750 ? 230 years B.P. was determined for materials immediately above three feet of older organic-rich clay layers. This dated material correlates with the upper part of the pollen T zone reported elsewhere in Connecticut and New York.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77545","usgsCitation":"Kelley, G.C., 1977, Late Pleistocene and Recent geology of the Housatonic River region in northwestern Connecticut: U.S. Geological Survey Open-File Report 77-545, [12], 222 leaves :ill., maps, plates (fold. in envelope) ;28 cm.; (222 p., 9 sheets - PGS), https://doi.org/10.3133/ofr77545.","productDescription":"[12], 222 leaves :ill., maps, plates (fold. in envelope) ;28 cm.; (222 p., 9 sheets - PGS)","costCenters":[],"links":[{"id":142786,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0545/report-thumb.jpg"},{"id":37540,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37541,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37542,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37543,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37544,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37545,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37546,"rank":406,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0545/plate-7.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37547,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0545/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8b71","contributors":{"authors":[{"text":"Kelley, George C.","contributorId":51294,"corporation":false,"usgs":true,"family":"Kelley","given":"George","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":160283,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate. The solutions are monitored for the concentration of uranium and selected additional elements (Si, K, Li, F), and the glass is recovered and examined for physical and/or chemical evidence of attack. The flushing mode is designed to mimic leaching of glass shards by intermittent, near-surface waters with which the glass is not in equilibrium. \r\n\r\nReported rates are applicable only to the experimental conditions (120?C, 7,000 psi), but it is assumed that the reaction mechanisms and the relative importance of rate-influencing parameters remain unchanged, at reduced temperature and pressure. Results of the above experiment indicate that silica and uranium are released from glass shards at comparable rates, while lithium and potassium are released faster and fluorine slower than either Si or U. Rates of release of silica and uranium correlate positively with the surface area of the shards. Rhyolitic shards release uranium at faster rates than rhyodacitic shards of comparable surface area. Changes in the shards resulting from experimental treatment and observed in the original glass separates from an Oligocene ash (compared to a Pleistocene ash) include; surface pitting, increased surface area, devitrification rinds (<1l micron wide) and reduced lithium contents. Future investigations will study the effect of temperature, pressure, solution composition, and flow rate on the relative mobility of U, Si, Li, F, and K.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77744","usgsCitation":"Zielinski, R.A., 1977, Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass: U.S. Geological Survey Open-File Report 77-744, 36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS), https://doi.org/10.3133/ofr77744.","productDescription":"36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS)","costCenters":[],"links":[{"id":145048,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0744/report-thumb.jpg"},{"id":39701,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0744/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db60541a","contributors":{"authors":[{"text":"Zielinski, Robert A. 0000-0002-4047-5129 rzielinski@usgs.gov","orcid":"https://orcid.org/0000-0002-4047-5129","contributorId":1593,"corporation":false,"usgs":true,"family":"Zielinski","given":"Robert","email":"rzielinski@usgs.gov","middleInitial":"A.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":163765,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Specifically, the mathematical model describes the three-dimensional flow of both single- and two-phase, single-component water and the transport of heat in porous media. The derivation begins with the point balance equations for mass, momentum, and energy. These equations are then averaged over a finite volume to obtain the macroscopic balance equations for a porous medium. The macroscopic equations are combined by appropriate constitutive relationships to form two similified partial differential equations posed in terms of fluid pressure and enthalpy. A two-dimensional formulation of the simplified equations is also derived by partial integration in the vertical dimension.

The lava rock aquifer contains water that is almost as saline as seawater. The saline water is below a seaward-discharging freshwater lens, and separated from it by a transition zone of varying salinity. Injection of wastewater at an average rate of 6.2 cubic feet per second is planned through wells open only to the aquifer deep within the saline water zone. The lava rock aquifer is overlain by a sequence of residual soil, clay, coral reef deposits, and marine sand that form a low-permeability caprock which semiconfines the lava rock aquifer.</p><p>A two-dimensional finite-difference model was used to describe initial conditions within the freshwater part of the aquifer, and to indicate response of the freshwater part of the system to injection of wastewater. Steady-state distribution of the wastewater within the saline and the freshwater parts of the lava rock aquifer was simulated by use of a three-dimensional finite-difference model. This model, using vertical-to-horizontal ratios of hydraulic conductivity of 1:10 and 1:100, shows that wastewater with a lesser density than that of either the saline or freshwater aquifer, will form a roughly cylindrical column around the injection well base and rise through the transition zones into the freshwater lens flow system. The column diameter varies with the ratio, and the column, or plume, widens progressively through the transition zone, then maintains virtually constant size through the freshwater part of the lava rock aquifer. Seaward flow within the freshwater lens tends to distort the plume seaward.</p><p>Under conditions measured and assumed for the study, it is evident that wastewater injected at the planned rate will move upward, then seaward without significant change. After reaching a new steady state, the wastewater will discharge into and through the caprock sequence within an area measuring approximately 1,000 feet inland, 1,000 feet laterally on either side of the injection site, and about 2,000 feet seaward. Little, if any, of the injected wastewater may be expected to reach the upper part of the caprock flow system landward of the treatment plant facility. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr77469","collaboration":"Prepared in cooperation with County of Maui Department of Public Works","usgsCitation":"Burnham, W., Larson, S.P., and Cooper, H.H., 1977, Distribution of injected wastewater in the saline-lava aquifer, Wailuku-Kahului wastewater treatment facility, Kahului, Maui, Hawaii: U.S. Geological Survey Open-File Report 77-469, vii, 58 p., https://doi.org/10.3133/ofr77469.","productDescription":"vii, 58 p.","costCenters":[],"links":[{"id":396612,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0469/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":140647,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0469/report-thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kahului, Maui","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.48788452148438,\n              20.873568860790446\n            ],\n            [\n              -156.44325256347656,\n              20.873568860790446\n            ],\n            [\n              -156.44325256347656,\n              20.903720104844798\n            ],\n            [\n              -156.48788452148438,\n              20.903720104844798\n            ],\n            [\n              -156.48788452148438,\n              20.873568860790446\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae78c","contributors":{"authors":[{"text":"Burnham, W.L.","contributorId":58668,"corporation":false,"usgs":true,"family":"Burnham","given":"W.L.","email":"","affiliations":[],"preferred":false,"id":157172,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larson, Steven P.","contributorId":78718,"corporation":false,"usgs":true,"family":"Larson","given":"Steven","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":157173,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cooper, Hilton H.","contributorId":106867,"corporation":false,"usgs":true,"family":"Cooper","given":"Hilton","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":157174,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
