Methodology","docAbstract":"<p><span>A new photoclinometric technique for extraction of topographic data from single planetary images is presented that overcomes many previous limitations of photoclinometry. The procedure fully compensates for oblique viewing geometry prevalent in spacecraft images. Albedo variations have been one of the most serious obstacles in the application of photoclinometry to planetary surfaces. This problem is overcome in the topographic solution by simultaneously utilizing brightness data from a pair of profiles; both segments are assumed to have the same topographic and albedo variations along their lengths. Profile directions are chosen where the orientation of downslope or upslope is obvious, thus resolving a major ambiguity in photoclinometry. This requirement is particularly easy to satisfy for craters and not very difficult for many irregular features. An additional procedure is presented that eliminates even the requirement of topographic symmetry along the pair of profiles. If two profiles have the same relief but their shapes are very different, another method can be used in an iterative process to derive topographic profiles; however, this procedure does, require that the albedo not vary along the profiles. Test results indicate that both procedures have an accuracy and precision of approximately 2° for slopes of typical bowl-shaped craters, which translates to approximately 5% for depths.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB089iB11p09449","issn":"01480227","usgsCitation":"Davis, P.A., and Soderblom, L., 1984, Modeling crater topography and albedo from monoscopic Viking orbiter images: 1.

The distribution of vents maps the areal zonation inferred for the upper parts of the Coso magmatic system. Subalkalic basalts (&lt;50% SiO<sub>2</sub>) were erupted well away from the rhyolite field at any given time. Compositional variation among these basalts can be ascribed to crystal fractionation. Erupted volumes of these basalts decrease with increasing differentiation. Mafic lavas containing up to 58% SiO<sub>2</sub>, erupted adjacent to the rhyolite field, formed by mixing of basaltic and silicic magma. Basaltic magma interacted with crustal rocks to form other SiO<sub>2</sub>-rich mafic lavas erupted near the Sierra Nevada fault zone.</p><p class=\"Para\">Several rhyolite domes in the Coso volcanic field contain sparse andesitic inclusions (55–61% SiO<sub>2</sub>). Pillow-like forms, intricate commingling and local diffusive mixing of andesite and rhyolite at contacts, concentric vesicle distribution, and crystal morphologies indicative of undercooling show that inclusions were incorporated in their rhyolitic hosts as blobs of magma. Inclusions were probably dispersed throughout small volumes of rhyolitic magma by convective (mechanical) mixing. Inclusion magma was formed by mixing (hybridization) at the interface between basaltic and rhyolitic magmas that coexisted in vertically zoned igneous systems. Relict phenocrysts and the bulk compositions of inclusions suggest that silicic endmembers were less differentiated than erupted high-silica rhyolite. Changes in inferred endmembers of magma mixtures with time suggest that the steepness of chemical gradients near the silicic/mafic interface in the zoned reservoir may have decreased as the system matured, although a high-silica rhyolitic cap persisted.</p><p class=\"Para\">The Coso example is an extreme case of large thermal and compositional contrast between inclusion and host magmas; lesser differences between intermediate composition magmas and inclusions lead to undercooling phenomena that suggest smaller ΔT. Vertical compositional zonation in magma chambers has been documented through study of products of voluminous pyroclastic eruptions.

These telluride minerals have so far not been identified. The nearby Brewer mine, on the basis of chemical evidence, also contains tellurides. The probable telluride localities in South Carolina are now expanded to three, significantly increasing the few reports of Te minerals from the Au deposits of the southeastern Piedmont, many of which are now considered to be volcanogenic. The occurrence of telluride minerals in gold ore from the Haile-Brewer area may help to explain the divergence in Au/Ag ratios reported in chemical analyses of drill core, ore samples and production records. Te, in addition, may be useful in geochemical exploration programmes in the SE Piedmont, including programmes using heavy mineral concentrates derived from stream alluvium. -R.S.M.","language":"English","issn":"00383678","usgsCitation":"Bell, H., and Larson, R., 1984, A new occurrence of telluride minerals in South Carolina: Southeastern Geology, v. 24, no. 4, p. 189-194.","productDescription":"6 p.","startPage":"189","endPage":"194","numberOfPages":"6","costCenters":[],"links":[{"id":220251,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States ","state":"South Carolina ","county":"Lancaster County ","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-80.8405,35.0016],[-80.7828,34.9349],[-80.7888,34.8809],[-80.796,34.8175],[-80.6779,34.8166],[-80.5614,34.8157],[-80.5559,34.8013],[-80.5437,34.7853],[-80.5303,34.7798],[-80.5247,34.7707],[-80.5141,34.7666],[-80.5153,34.7593],[-80.4904,34.7229],[-80.4871,34.7061],[-80.476,34.6983],[-80.4599,34.6787],[-80.4516,34.6759],[-80.4488,34.6682],[-80.4394,34.6604],[-80.4332,34.6599],[-80.4305,34.6576],[-80.4344,34.6477],[-80.4339,34.6404],[-80.4228,34.6344],[-80.4122,34.6271],[-80.4168,34.6162],[-80.5511,34.5605],[-80.5451,34.5505],[-80.5418,34.5382],[-80.5379,34.5337],[-80.5335,34.5282],[-80.5296,34.5218],[-80.5247,34.5095],[-80.5258,34.505],[-80.5442,34.5033],[-80.5488,34.4933],[-80.5599,34.4938],[-80.5666,34.4897],[-80.5772,34.4852],[-80.5795,34.4847],[-80.5828,34.4934],[-80.5861,34.497],[-80.595,34.5021],[-80.6301,34.499],[-80.6252,34.489],[-80.6274,34.4831],[-80.6324,34.4808],[-80.6408,34.4845],[-80.6452,34.4836],[-80.6587,34.4786],[-80.6764,34.4932],[-80.6825,34.501],[-80.6831,34.5073],[-80.6886,34.5155],[-80.6981,34.516],[-80.7065,34.5097],[-80.7098,34.5047],[-80.7121,34.4956],[-80.7132,34.4879],[-80.7289,34.4825],[-80.7345,34.4811],[-80.7384,34.482],[-80.7406,34.4807],[-80.7417,34.4852],[-80.7456,34.4889],[-80.7456,34.492],[-80.74,34.5016],[-80.7394,34.507],[-80.7449,34.5102],[-80.7461,34.5129],[-80.7393,34.5247],[-80.7393,34.5352],[-80.7376,34.5397],[-80.7437,34.5402],[-80.8677,34.4641],[-80.8794,34.4582],[-80.8883,34.4682],[-80.8961,34.4841],[-80.8961,34.4936],[-80.8821,34.5004],[-80.8754,34.5336],[-80.8776,34.5436],[-80.8787,34.5463],[-80.8765,34.569],[-80.8781,34.5813],[-80.8831,34.5886],[-80.8921,34.5976],[-80.8892,34.6185],[-80.8909,34.624],[-80.8959,34.6295],[-80.897,34.6358],[-80.8886,34.6631],[-80.8774,34.683],[-80.8606,34.6957],[-80.86,34.7003],[-80.8617,34.7034],[-80.8662,34.7062],[-80.8684,34.7153],[-80.8684,34.7234],[-80.8745,34.7316],[-80.8778,34.7434],[-80.8784,34.7593],[-80.8761,34.7857],[-80.8839,34.7948],[-80.8901,34.8052],[-80.8951,34.8125],[-80.8979,34.8207],[-80.899,34.8247],[-80.8979,34.8279],[-80.8755,34.8374],[-80.8665,34.8483],[-80.8687,34.8556],[-80.8766,34.8597],[-80.8788,34.8624],[-80.8799,34.8751],[-80.8782,34.8888],[-80.8793,34.8983],[-80.8782,34.9038],[-80.8748,34.9065],[-80.8681,34.9124],[-80.8652,34.9224],[-80.8658,34.9264],[-80.8691,34.9314],[-80.873,34.96],[-80.877,34.9614],[-80.8848,34.9601],[-80.887,34.9619],[-80.8859,34.9791],[-80.8971,34.9946],[-80.8999,35.005],[-80.8988,35.0109],[-80.9027,35.0105],[-80.9055,35.0127],[-80.9032,35.0259],[-80.8982,35.0364],[-80.906,35.0495],[-80.9016,35.0716],[-80.8854,35.0535],[-80.8604,35.0246],[-80.8405,35.0016]]]},\"properties\":{\"name\":\"Lancaster\",\"state\":\"SC\"}}]}","volume":"24","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e4ade4b0c8380cd46827","contributors":{"authors":[{"text":"Bell, H.","contributorId":97630,"corporation":false,"usgs":true,"family":"Bell","given":"H.","affiliations":[],"preferred":false,"id":365900,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larson, R.R.","contributorId":29803,"corporation":false,"usgs":true,"family":"Larson","given":"R.R.","email":"","affiliations":[],"preferred":false,"id":365899,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These accretionary modes are:</p><ul class=\"list\"><li class=\"react-xocs-list-item\"><span class=\"list-label\">1.</span><p>(1) hydrogenous,<span>&nbsp;</span><i>i.e</i>., direct precipitation or accumulation of colloidal metal oxides in seawater,</p></li><li class=\"react-xocs-list-item\"><span class=\"list-label\">2.</span><p>(2) oxic diagenesis which refers to a variety of ferromanganese accretion processes occurring in oxic sediments; and</p></li><li class=\"react-xocs-list-item\"><span class=\"list-label\">3.</span><p>(3) suboxic diagenesis which results from reduction of Mn<sup>+4</sup><span>&nbsp;</span>by oxidation of organic matter in the sediments. Geochemical evidence suggests processes (1) and (2) occur at all three MANOP nodule-bearing sites, and process (3) occurs only at the hemipelagic site, H, which underlies the relatively productive waters of the eastern tropical Pacific.</p></li></ul><p>A normative model quantitatively accounts for the variability observed in nearly all elements. Zn and Na, however, are not well explained by the three end-member model, and we suggest that an additional accretionary process results in greater variability in the abundances of these elements. Variable contributions from the three accretionary processes result in distinct top-bottom compositional differences at the three sites. Nodule tops from H are enriched in Ni, Cu, and Zn, instead of the more typical enrichments of these elements in nodule bottoms. In addition, elemental correlations typical of most pelagic nodules are reversed at site H.</p><p>The three accretionary processes result in distinct mineralogies. Hydrogenous precipitation produces δMnO<sub>2</sub>. Oxic diagenesis, however, produces Cu-Ni-rich todorokite, and suboxic diagenesis results in an unstable todorokite which transforms to a 7 Å phase (“birnessite”) upon dehydration. The presence of Cu and Ni as charge-balancing cations influence the stability of the todorokite structure. In the bottoms of H nodules, which accrete dominantly by suboxic diagenesis, Na<sup>+</sup><span>&nbsp;</span>and possibly Mn<sup>+2</sup><span>&nbsp;</span>provide much of the charge balance for the todorokite structure.</p><p>Limited growth rate data for H nodules suggest suboxic accretion is the fastest of the three processes, with rates at least 200 mm/10<sup>6</sup><span>&nbsp;</span>yr. Oxic accretion is probably 10 times slower and hydrogenous 100 times slower. Since these rates predict more suboxic component in bulk nodules than is calculated by the normative analysis, we propose that suboxic accretion is a non-steady-state process. Variations in surface water productivity cause pulses of particulate flux to the sea floor which result in transient Mn reduction in the surface sediments and reprecipitation on nodule surfaces.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(84)90186-8","issn":"00167037","usgsCitation":"Dymond, J., Lyle, M., Finney, B., Piper, D., Murphy, K., Conard, R., and Pisias, N., 1984, Ferromanganese nodules from MANOP Sites H, S, and R-Control of mineralogical and chemical composition by multiple accretionary processes: Geochimica et Cosmochimica Acta, v. 48, no. 5, p. 931-949, https://doi.org/10.1016/0016-7037(84)90186-8.","productDescription":"19 p.","startPage":"931","endPage":"949","numberOfPages":"19","costCenters":[],"links":[{"id":220526,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0f87e4b0c8380cd53937","contributors":{"authors":[{"text":"Dymond, J.","contributorId":98461,"corporation":false,"usgs":true,"family":"Dymond","given":"J.","email":"","affiliations":[],"preferred":false,"id":365653,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lyle, M.","contributorId":40344,"corporation":false,"usgs":true,"family":"Lyle","given":"M.","email":"","affiliations":[],"preferred":false,"id":365649,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Finney, B.","contributorId":72125,"corporation":false,"usgs":true,"family":"Finney","given":"B.","affiliations":[],"preferred":false,"id":365651,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Piper, D.Z.","contributorId":34154,"corporation":false,"usgs":false,"family":"Piper","given":"D.Z.","email":"","affiliations":[],"preferred":false,"id":365648,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Murphy, K.","contributorId":89865,"corporation":false,"usgs":false,"family":"Murphy","given":"K.","email":"","affiliations":[],"preferred":false,"id":365652,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Conard, R.","contributorId":63531,"corporation":false,"usgs":true,"family":"Conard","given":"R.","email":"","affiliations":[],"preferred":false,"id":365650,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pisias, N.","contributorId":25290,"corporation":false,"usgs":true,"family":"Pisias","given":"N.","affiliations":[],"preferred":false,"id":365647,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

A strong positive correlation has been found between formation-water salinity and Ra activity, resulting from the interaction of formation water with aquifer matrix. Ra isotopes enter the fluid phase after being produced by the decay of parent elements U and Th, which are located at sites on and within the solid matrix. Processes that are belived to be primarily responsible for transferring Ra from matrix to formation water are chemical leaching and alpha-particle recoil. Factors controlling the observed salinity-Ra relationship may be one or a combination of the following factors: (a) ion exchange; (b) increased solubility of matrix silica surrounding Ra atoms, coupled with a salinity-controlled rate of reequilibration of silica between solution and quartz grains; and (c) the equilibration of Ra in solution with detrial barite within the aquifer. No difference was found in the brine-Ra relation in water produced from oil or gas wells and water produced from wells penetrating only water-bearing aquifers, although the relation was more highly correlated for water-bearing aquifers than hydrocarbon-containing reservoirs. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0009-2541(84)90186-4","issn":"00092541","usgsCitation":"Kraemer, T.F., and Reid, D., 1984, The occurrence and behavior of radium in saline formation water of the U.S. Gulf Coast region: Chemical Geology, v. 46, no. 2, p. 153-174, https://doi.org/10.1016/0009-2541(84)90186-4.","startPage":"153","endPage":"174","numberOfPages":"22","costCenters":[],"links":[{"id":266106,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0009-2541(84)90186-4"},{"id":219659,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bae31e4b08c986b323f48","contributors":{"authors":[{"text":"Kraemer, T.

The technique uses solvent extraction followed by gas chromatographic separation and detection employing nitrogen-selective devices. Seven compounds can be determined simultaneously at a nominal detection limit of 0.1 μg/L in a 1-litre sample. Three different natural water samples were used for error analysis via evaluation of recovery efficiencies and estimation of overall method precision. As an alternative to liquid-liquid partition (solvent extraction) for removal of compounds of interest from water, solid-phase extraction (SPE) techniques employing chromatographic grade silicas with chemically modified surfaces have been examined. SPE is found to provide rapid and efficient concentration with quantitative recovery of some triazine herbicides from natural water samples. Concentration factors of 500 to 1000 times are obtained readily by the SPE technique.</p></div></div>","language":"English","publisher":"Taylor and Francis ","doi":"10.1080/03067318408079923","issn":"03067319","usgsCitation":"Steinheimer, T., and Brooks, M., 1984, Development and evaluation of a gas chromatographic method for the determination of triazine herbicides in natural water samples: International Journal of Environmental Analytical Chemistry, v. 17, no. 2, p. 97-111, https://doi.org/10.1080/03067318408079923.","productDescription":"15 p.","startPage":"97","endPage":"111","numberOfPages":"15","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":220195,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-02-23","publicationStatus":"PW","scienceBaseUri":"505a001fe4b0c8380cd4f5d4","contributors":{"authors":[{"text":"Steinheimer, T.R.","contributorId":106166,"corporation":false,"usgs":true,"family":"Steinheimer","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":365891,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brooks, M.G.","contributorId":103410,"corporation":false,"usgs":true,"family":"Brooks","given":"M.G.","email":"","affiliations":[],"preferred":false,"id":365890,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Within this wedge, seismic reflection profiles reveal an abundance of potential hydrocarbon-trapping structures. These structures include antiforms, thrust and normal faults, and stratigraphic pinchouts. Maximum closure on these features is 2 km. In addition, the silt and possibly sand size sediment within the offscraped turbidite deposits, and the porous diatomaceous pelagic deposits interbedded with and at the base of the wedge, may define suitable reservoirs for the entrapment of hydrocarbons. Potential seals for these reservoirs include diagenetically-altered and -produced siliceous and carbonate sediment. The organic carbon input into the central Aleutian Trench, based on carbon analyses of DSDP Legs 18 and 19 core samples, suggests that the average organic carbon content within the accretionary body is approximately 0.3-0.6%. Heat flow across the Aleutian Terrace indicates that at present the oil generation window lies at a depth of 3-6.5 km. At depths of 8 km (which corresponds to the maximum depth the offscraped sediment has been seismically resolved beneath the lower trench slope), the probable high (170-180??C) temperatures prohibit all but gas generation. The dewatering of trench sediment and subducted oceanic crust should produce an abundance of fluids circulating within the accretionary body. These fluids and gases can conduct hydrocarbons to any of the abundant trapping geometries or be lost from the system through sea floor seepage. In the Aleutian accretionary body all the conditions necessary for the formation of oil and gas deposits exist. The size and ultimate preservation of these deposits, however, are dependent on the deformational history of the prism both during accretion and after the accretion process has been superceded by subsequent tectonic regimes. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0264-8172(84)90083-7","issn":"02648172","usgsCitation":"McCarthy, J., Stevenson, A., Scholl, D., and Vallier, T., 1984, Speculations on the petroleum geology of the accretionary body: an example from the central Aleutians: Marine and Petroleum Geology, v. 1, no. 2, p. 151-167, https://doi.org/10.1016/0264-8172(84)90083-7.","startPage":"151","endPage":"167","numberOfPages":"17","costCenters":[],"links":[{"id":268658,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0264-8172(84)90083-7"},{"id":220577,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b95b8e4b08c986b31b0a0","contributors":{"authors":[{"text":"McCarthy, J.","contributorId":50290,"corporation":false,"usgs":true,"family":"McCarthy","given":"J.","affiliations":[],"preferred":false,"id":365655,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stevenson, A.J.","contributorId":27864,"corporation":false,"usgs":true,"family":"Stevenson","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":365654,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Scholl, D.W.","contributorId":106461,"corporation":false,"usgs":true,"family":"Scholl","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":365657,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vallier, T.L.","contributorId":69526,"corporation":false,"usgs":true,"family":"Vallier","given":"T.L.","affiliations":[],"preferred":false,"id":365656,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Glacial Priest Lake, dammed in the Priest River valley by a tongue of the Purcell trench lobe of the Cordilleran ice sheet, generally accumulated varved mud; the varved mud is sharply interrupted by 14 sand beds deposited by upvalley-running currents. The sand beds are texturally and structurally similar to slackwater sediment in valleys in southern Washington that were backflooded by outbursts from glacial Lake Missoula. Beds of varved mud also accumulated in glacial Lake Spokane (or Columbia?) in Latah Creek valley and elsewhere in northeastern Washington; the mud beds were disrupted, in places violently, during emplacement of each of 16 or more thick flood-gravel beds. This history corroborates evidence from southern Washington that only one graded bed is deposited per flood, refuting a conventional idea that many beds accumulated per flood. The total number of such floodlaid beds in stratigraphic succession near Spokane is at least 28. The mud beds between most of the floodlaid beds in these valleys each consist of between 20 and 55 silt-to-clay varves.

Documented penetration by the SIR-A signal of dry surficial sediment to depths of a meter or more revealed bedrock geologic features and networks of former stream valleys otherwise concealed beneath windblown sand, alluvium, and colluvial deposits. 'Radar units' mapped on SIR-A images according to relative brightness and degree of mottling correspond to subsurface geologic and topographic features identified in more than 50 test pits. Petrologic examination of pit samples confirms that a variety of depositional environments existed in this now hyper-arid region before it was mantled by windblown sand sheets and dunes. Wet sand was discovered in two buried valleys shown on the radar images and located in the field with the aid of co-registered maps and Landsat images, and a satellite navigation device. Buried valleys whose streams once traversed mineralized zones are potential sites of placers (gold, tin).","conferenceTitle":"Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology.","conferenceLocation":"Colorado Springs, CO, USA","language":"English","publisher":"Environmental Research Inst of Michigan","publisherLocation":"Ann Arbor, MI, USA","usgsCitation":"Breed, C.S., McCauley, J., and Schaber, G.G., 1984, SHUTTLE IMAGING RADAR PROVIDES FRAMEWORK FOR SUBSURFACE GEOLOGIC EXPLORATION IN EGYPT AND SUDAN., Proceedings of the International Symposium on Remote Sensing of Environment, Third Thematic Conference: Remote Sensing for Exploration Geology., Colorado Springs, CO, USA.","startPage":"949","costCenters":[],"links":[{"id":219916,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaf4ce4b0c8380cd874eb","contributors":{"authors":[{"text":"Breed, Carol S.","contributorId":100904,"corporation":false,"usgs":true,"family":"Breed","given":"Carol","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":365957,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McCauley, John F.","contributorId":54973,"corporation":false,"usgs":true,"family":"McCauley","given":"John F.","affiliations":[],"preferred":false,"id":365956,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schaber, Gerald G.","contributorId":12511,"corporation":false,"usgs":true,"family":"Schaber","given":"Gerald","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":365955,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A host cellular response to zygotes and oocysts was noted in the majority of infected adult geese. Heavily infected kidneys were hypertrophic with minute foci on the surface of the organ. Histological examinations showed large numbers of unsporulated oocysts accumulated in distended collecting tubules, resulting in pressure necrosis to adjacent tissue and urate retention. Zygotes were observed in the cytoplasm of tubule cells and extracellularly in interstitial tissue. Infected tubule cells were characterized by the peripheral location of the nuclei, cytoplasmic basophilia, and cellular hypertrophy.
