The effect of progressive natural weathering on the isotopic (Rb-Sr, K-Ar, δD, δ18O) and chemical (REE, H2O+) compositions of biotite has been studied on a suite of migmatitic biotites from the Chad Republic. During the early stages of weathering the Rb-Sr system is strongly affected, the hydrogen and oxygen isotope compositions change markedly, the minerals are depleted in light REE, the water content increases by a factor of two, and the K-Ar system is relatively little disturbed. During intensive weathering the K-Ar system is more strongly disturbed than the Rb-Sr system.
Most of the isotopic and chemical modifications take place under nonequilibrium conditions and occur before newly formed kaolinite and/or smectite can be detected. These observations suggest that
(a) “protominerals” may form within the biotite structure during the initial period of weathering, and
(b) only when chemical equilibrium is approached in the weathering profile are new minerals able to form.
A low compressional-wave velocity region in the midcrust below the San Francisco Mountain stratovolcano, Arizona, has been detected by the teleseismic P residual technique. This region is approximately 6 km wide, lies between elevations of 9 km and 34 km below sea level, and has a compressional velocity reduction of more than 6% with respect to the surrounding rocks. Several mechanisms are found to be quantitatively sufficient to produce such a feature. These include (1) a cool silicic pluton enclosed in a more mafic crust, (2) high temperature (near but below the solidus) in a quartz-bearing rock in the low-velocity region, (3) high density of water-filled cracks having pore pressures nearly equal to lithostatic pressure, and (4) the presence of melt, either in intergranular pores or in crystal-poor dikes.

Porosity data are derived from borehole-gravity measurements and from suites of acoustic, neutron, and density logs. Both types of wire-line measurements sample large volumes of rock relative to petrographic methods and can be examined at vertical scales approaching those of aquifers and hydrocarbon reservoirs. Investigation depths range from the surface to about 18,000 ft (5,500 m) and span the transition from high-porosity near-surface carbonate sediments of Pleistocene age to much denser Mesozoic carbonate rocks with porosities of only a few percent.
Carbonate porosity in the South Florida basin was affected by a variety of diagenetic processes. However, a number of factors that could complicate porosity-depth relations are of limited importance in southern Florida. The basin contains little clastic material; present depths of burial are about equal to maximum depths of burial; the influences of tectonism, geopressures, and hydrocarbon accumulations are minimal.
Curves of porosity versus depth, reflecting large-scale porosity-loss processes in the subsurface, are derived for a composite carbonate section and for carbonate strata of different ages and compositions. The decrease of porosity with depth for a composite carbonate section representing a wide range of depositional environments and subsequent diagenetic histories can be characterized by the exponential function ^phgr = 41.73e -z8197/ (ft) [^phgr = 41.73e-z2498/ (m)], where ^phgr is the porosity (%) and z is the depth below ground level (feet or meters). Average porosity is reduced by a factor of two in a depth interval of about 5,700 ft (1,740 m).
Carbonate strata of different ages that are buried to equal depths show no systematic porosity differences. This implies that the effect of time on porosity in these rocks is probably subordinate to that of burial depth. The data also show a faster than expected rate of porosity decrease with depth for rocks of Eocene age and younger. If it is assumed that the decrease in the volume of evaporites in these rocks indicates less saline pore fluids, porosity loss in shallow-water carbonates may be inversely related to the magnesium content of pore waters.
Dolomite porosity is lower than limestone porosity in the near surface, but does not decrease as rapidly with depth. Below about 5,600 ft (1,700 m), dolomite is more porous than limestone. It is hypothesized that most dolomitization occurred relatively early and either reduced original porosity or selectively favored lower-porosity limestones. With continued burial, dolomite was more resistant than limestone to associated porosity-reducing effects.

Two scales of prior information can be available: (1) prior information having known reliability (that is, bias and random error structure) and (2) prior information consisting of best available estimates of unknown reliability. A regression method that incorporates the second scale of prior information assumes the prior information to be fixed for any particular analysis to produce improved, although biased, parameter estimates. Approximate optimization of two auxiliary parameters of the formulation is used to help minimize the bias, which is almost always much smaller than that resulting from standard ridge regression. It is shown that if both scales of prior information are available, then a combined regression analysis may be made.

All of the fissure zones; which have a cumulative length of >8.7 km, occur above either ridges or steps in the bedrock surface. Intersecting fissure zones overlie intersecting bedrock features, and the angle of intersection of the zones accurately reflects the angle between the bedrock features. These relations suggest that the fissures are forming in response to localized differential compaction caused by localized variations of aquifer-system thickness. Topographic profiles across fissures on undisturbed desert floor confirm differential compaction proportional to the variations in aquifer thickness. The occurrence of the fissures at points of maximum convex-upward curvature in profiles of both the topographic and buried bedrock surfaces indicates that the fissures result from tensile strains caused by bending of the strata above the buried bedrock features in response to the differential compaction. Tensile strains at failure are estimated to range from ∼ 0.02% to 0.2% on the basis of modeling of the bending process.
The U.S. Geological Survey produces a variety of resource information for the United States. This includes many data bases of particular interest to planners such as land use and terrain information prepared by the National Mapping Division, water quantity and quality data collected by Water Resources Division, and coal resource information gathered by the Geologic Division. These data are stored in various forms, and information on their availability can be obtained from appropriate offices in the U.S. Geological Survey as well as from USGS Circular 777. These data have been used for the management, development, and monitoring of our Nation's resources by Federal, State, and local agencies.

Human infections are probably acquired by inhalation of aerosols containing elementary bodies of the causative agent Chlamydia psittaci, from bird droppings, or from tissues. Infected birds do not have to be ill to transmit the organism (Schachter and Dawson 1978). The disease in humans is considered an occupational risk for people working with pet birds (particularly psittacine species) and poultry, but all avian species can be considered as potential reservoirs (Schachter and Dawson 1978). Burkhart and Page (1971) listed >130 species of wild birds as being infected.
The purpose of this report is to draw the disease to the attention of those working with wild birds by describing 2 cases acquired from wild waterfowl and by reviewing other information on human infections associated with wild birds. We do this because the disease can be serious if not treated properly, and because the disease is not usually associated with wild birds the diagnosis may not be considered by physicians without some prompting from the patient.

The relative depth and time of siderite precipitation can be inferred from the structure, mineralogy and isotopic composition of these concretions. Concretions that formed at shallow depths, early in the history of the sediment, contain a high percentage (75-85%) of carbonate, preserve uncompacted structures and have oxygen isotopic ratios similar to that of sea-water. In contrast, concretions that formed later and/or at greater depths have lower carbonate content and lower 18O/16O ratios. Concretions in rapidly deposited sediments formed at shallow depths (<10 m), and those in sediments that accumulated slowly formed at greater depths. These differences agree with the fossil evidence. Siderite did not form until nearly all the dissolved sulphur had been reduced and precipitated as pyrite; the excess organic matter produced methane at about the same time.-H.R.B.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Sedimentary Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00224472","usgsCitation":"Gautier, D.L., 1982, Siderite concretions: indicators of early diagenesis in the Gammon shale (Cretaceous).: Journal of Sedimentary Petrology, v. 52, no. 3, p. 859-871.","startPage":"859","endPage":"871","numberOfPages":"13","costCenters":[],"links":[{"id":221127,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8ef2e4b08c986b318c3e","contributors":{"authors":[{"text":"Gautier, D.

Si, Li, and V are also preferentially mobilized by glass dissolution. Gaseous transfer followed by fixation of soluble uranium species on volcanic-ash particles is not an important process affecting uranium mobility. Gaseous transfer, however, may be important in forming water-soluble phases, adsorbed to ash surfaces, enriched in the economically and environmentally important elements Zn, Cu, Cd, Pb, B, F, and Ba. Quick removal of these adsorbed elements by the first exposure of freshly erupted ash to rain and surface water may pose short-term hazards to certain forms of aquatic and terrestrial life. Such rapid release of material may also represent the first step in transportation of economically important elements to environments favorable for precipitation into deposits of commercial interest. Ash samples collected from the active Guatemalan volcanoes Fuego and Pacaya (high-Al basalts) and Santiaguito (hornblende-hypersthene dacite); bomb fragments from Augustine volcano (andesite-dacite), Alaska, and Heimaey (basalt), Vestmann Islands, Iceland; and fragments of \"rhyolitic\" pumice from various historic eruptions were subjected to three successive leaches with a constant water-to-ash weight ratio of 4:1. The volcanic material was successively leached by: (1) distilled-deionized water (pH = 5.0-5.5) at room temperature for 24 h, which removes water-soluble gases and salts adsorbed on ash surfaces during eruption; (2) dilute HCl solution (pH = 3.5-4.0) at room temperature for 24 h, which continues the attack initiated by the water and also attacks acid-soluble sulfides and oxides; (3) a solution 0.05 M in both Na,CO, and NaHCO, (pH = 9.9) at 80°C for one week, which preferentially dissolves volcanic glass. The first two leaches mimic interaction of ash with rain produced in the vicinity of an active eruption. The third leach accelerates the effect of prolonged contact of volcanic ash with alkaline ground water present during ash diagenesis.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0377-0273(82)90017-8","issn":"03770273","usgsCitation":"Smith, D.B., Zielinski, R.A., and Rose, W., 1982, Leachability of uranium and other elements from freshly erupted volcanic ash: Journal of Volcanology and Geothermal Research, v. 13, no. 1-2, p. 1-30, https://doi.org/10.1016/0377-0273(82)90017-8.","productDescription":"30 p.","startPage":"1","endPage":"30","costCenters":[],"links":[{"id":221397,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267294,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0377-0273(82)90017-8"}],"volume":"13","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4597e4b0c8380cd6742e","contributors":{"authors":[{"text":"Smith, D.

Reproducibility of biodegradation in the RDA test was analyzed under conditions in which the test is commonly done. Biodegradation results were not reproducible for di-2-ethylexyl phthalate (DEHP) and phthalic acid in replicated RDA tests using Missouri River water. Chemical and biological changes during the RDA tests probably reflected relative laboratory conditions. Initial suspended solids and subsequent DEHP biodegradation were directly related. Interpretation of RDA test results is enhanced by replicating experiments and comparing biodegradation of the test compound with a compound whose degradation properties are known. However, biodegradation measured with the RDA test is too variable and too dependent on laboratory treatment of samples to apply results directly to the aquatic environment.

Monte Carlo experiments were used to compare the performance of several alternative methods for estimating the standard deviation σ of a lag one autoregressive model in terms of bias, root mean square error, probability of underestimation, and expected opportunity design loss. Three methods provided estimates of σ which were much less biased but had greater mean square errors than the usual estimate of σ: s = (1/(n - 1) ∑ (xi −x¯)2)½. The three methods may be briefly characterized as (1) a method using a maximum likelihood estimate of the unbiasing factor, (2) a method using an empirical Bayes estimate of the unbiasing factor, and (3) a robust nonparametric estimate of σ suggested by Quenouille. Because s tends to underestimate σ, its use as an estimate of a model parameter results in a tendency to underdesign. If underdesign losses are considered more serious than overdesign losses, then the choice of one of the less biased methods may be wise.

Presented here are techniques that are suitable in the face of the complications listed above for the exploratory analysis of monthly water quality data for monotonie trends. The first procedure described is a nonparametric test for trend applicable to data sets with seasonality, missing values, or values reported as ‘less than’: the seasonal Kendall test. Under realistic stochastic processes (exhibiting seasonality, skewness, and serial correlation), it is robust in comparison to parametric alternatives, although neither the seasonal Kendall test nor the alternatives can be considered an exact test in the presence of serial correlation. The second procedure, the seasonal Kendall slope estimator, is an estimator of trend magnitude. It is an unbiased estimator of the slope of a linear trend and has considerably higher precision than a regression estimator where data are highly skewed but somewhat lower precision where the data are normal. The third procedure provides a means for testing for change over time in the relationship between constituent concentration and flow, thus avoiding the problem of identifying trends in water quality that are artifacts of the particular sequence of discharges observed (e.g., drought effects). In this method a flow-adjusted concentration is defined as the residual (actual minus conditional expectation) based on a regression of concentration on some function of discharge. These flow-adjusted concentrations, which may also be seasonal and non-normal, can then be tested for trend by using the seasonal Kendall test.

DDT, DDD, DDE, PCB 's and chlordane are present in most surficial bed material samples. Diazinon was the only organophosphorous insecticide detected in the study (1.6 micrograms per kilogram at one location). High values for select trace metals in bed material were discovered at two locations. Of the 10 sites sampled, the surficial bed material containing the most contamination was found along one cross section of Raccoon Creek at Bridgeport. An additional analysis of Raccoon Creek revealed bed material containing toluene, oil and grease, and trace quantities of 15 base/neutral extractable organic compounds, including polynuclear aromatic hydrocarbons, phthalate esters, and chlorinated benzenes.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri8236","collaboration":"Prepared in cooperation with the New Jersey Department of Environmental Protection, Division of Water Resources","usgsCitation":"Hochreiter, J.J., 1982, Chemical-quality reconnaissance of the water and surficial bed material in the Delaware River estuary and adjacent New Jersey tributaries, 1980-81: U.S. Geological Survey Water-Resources Investigations Report 82-36, vii, 41 p., https://doi.org/10.3133/wri8236.","productDescription":"vii, 41 p.","numberOfPages":"50","onlineOnly":"Y","additionalOnlineFiles":"N","temporalStart":"1980-01-01","temporalEnd":"1981-12-31","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":158491,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_82_36.gif"},{"id":415449,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35530.htm","linkFileType":{"id":5,"text":"html"}},{"id":261852,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri82-36/","linkFileType":{"id":5,"text":"html"}},{"id":261853,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/wri82-36/pdf/wrir82-36.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"New Jersey","otherGeospatial":"Delaware River estuary","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -75.55,\n 40.144\n ],\n [\n -75.55,\n 39.9\n ],\n [\n -74.702,\n 39.9\n ],\n [\n -74.702,\n 40.144\n ],\n [\n -75.55,\n 40.144\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dee4b07f02db5e29ea","contributors":{"authors":[{"text":"Hochreiter, Joseph J.

Rectilinear features trend dominantly in N-S (± 10°), NNW and ENE, and less commonly in NW and EW directions. The Precambrian fractures closely match, and have possibly accommodated the Tertiary structures of the Red Sea rift.
\nProjection of the ENE continental fractures offshore on the basis of a modified trend due to rift movements, and \"principle of equidistances,\" corresponds with apparently more precise locations of possible transverse faults. Projections of the proposed transverse faults generally conform with breaks in bathymetric contours, and azimuth trend of the axial trough. Hot brine pools, shallow focus epicenters and anomalous heat flow measurements, all tend to lie at or close to the intersection of the transverse faults and axis of the deep waters. The transverse faults exhibit a general N35-50°E trend as compared with the N60-70_Etrend of the ancestor continental fractures. Deflection in trend caused by faults coinciding with the presnet shore line, may indicate lateral displacement prior to the initial hase of rifting in Miocene times. It also supports the hypothesis of a \"two-phase rifting\" of the Red Sea. Spreading movements proposed along transverse faults with trend values exceeding N50°E may not be applicable, at least for the more recent separation movements.

Increased emphasis on construction of new islands and manipulation of plant communities on existing islands should be considered for waterfowl management programs in the prairie and parkland regions of North America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Duebbert, H., 1982, Nesting of waterfowl on islands in Lake Audubon, North Dakota: Wildlife Society Bulletin, v. 10, no. 3, p. 232-237.","productDescription":"6 p.","startPage":"232","endPage":"237","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":133546,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -101.513671875,\n 47.42808726171425\n ],\n [\n -101.07421875,\n 47.42808726171425\n ],\n [\n -101.07421875,\n 47.70976154266637\n ],\n [\n -101.513671875,\n 47.70976154266637\n ],\n [\n -101.513671875,\n 47.42808726171425\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"10","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b12e4b07f02db6a2f03","contributors":{"authors":[{"text":"Duebbert, Harold F.","contributorId":11544,"corporation":false,"usgs":true,"family":"Duebbert","given":"Harold F.","affiliations":[],"preferred":false,"id":311240,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":47666,"text":"wri824041 - 1982 - Map showing altitude of the top of the Fox Hills-Lower Hell Creek aquifer, Montana","interactions":[],"lastModifiedDate":"2023-03-15T18:28:58.85572","indexId":"wri824041","displayToPublicDate":"1982-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"82-4041","title":"Map showing altitude of the top of the Fox Hills-Lower Hell Creek aquifer, Montana","docAbstract":"No abstract available.
