Moreover, only Se among the four measured elements exhibited a geographic (spatial) pattern that coincided with known inflows of tile drainage to the San Joaquin River and its tributaries. Historical data from the Grassland Water District (Grasslands; a region exposed to concentrated tile drainage) suggested that concentrations of Se in fishes were at maximum during or shortly after 1984 and have been slightly lower since then.

Approximately 65% of the dissolved organic carbon (DOC) was first removed on XAD-8 resin, and then an additional 20% of the DOC was removed on XAD-4 resin. Approximately 15% of the DOC solutes (primarily hydrophilic neutrals) were not sorbed or concentrated by the procedure. Of the 65% of the solutes removed on XAD-8 resin, 40% were fulvic acids, 16% were humic acids, and 9% were hydrophobic neutrals. Approximately 20% of the hydrophilic solutes that pass through the XAD-8 resin were sorbed solutes on the second resin, XAD-4 (i.e., they were hydrophobic relative to the XAD-4 resin). The fraction sorbed on XAD-4 resin was called XAD-4 acids because it represented approximately 85-90% of the hydrophilic XAD-8 acid fraction according to the original XAD-8 fractionation procedure. The recovery of hydrophobic acids (fulvic acids and humic acids) and the hydrophobic neutral fraction from XAD-8 resin was essentially quantitative at 96%, 98%, and 86%, respectively. The recovery of XAD-4 acids from the XAD-4 resin was only about 50%. The exact reason for this moderately low recovery is unknown, but could result from ??-?? bonding between these organic solutes and the aromatic matrix of XAD-4. The hydrophobic/hydrophilic solute separation on XAD-8 resin for water from background Side A and Side B of the lake was almost identical at 65 and 67%, respectively. This result suggested that both sides of the lake are similar in organic chemical composition even though the DOC variation from side to side is 20%.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environment International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0160-4120(92)90027-2","issn":"01604120","usgsCitation":"Malcolm, R., and MacCarthy, P., 1992, Quantitative evaluation of XAD-8 and XAD-4 resins used in tandem for removing organic solutes from water: Environment International, v. 18, no. 6, p. 597-607, https://doi.org/10.1016/0160-4120(92)90027-2.","startPage":"597","endPage":"607","numberOfPages":"11","costCenters":[],"links":[{"id":499877,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/9eb6773467144df0b779c5a985f4581f","text":"External Repository"},{"id":205568,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0160-4120(92)90027-2"},{"id":224898,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9217e4b0c8380cd80655","contributors":{"authors":[{"text":"Malcolm, Ronald L.","contributorId":46075,"corporation":false,"usgs":true,"family":"Malcolm","given":"Ronald L.","affiliations":[],"preferred":false,"id":374595,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"MacCarthy, P.","contributorId":88081,"corporation":false,"usgs":true,"family":"MacCarthy","given":"P.","email":"","affiliations":[],"preferred":false,"id":374596,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Stratigraphic, facies, and contact features of the caldera-related tuffs also provide constraints on the locations, lateral displacements, and very existence for some major northwest-trending faults and inferred regional thrusts in south-eastern Arizona. For example, the intricate Cochise thrust system, as mapped by others in the southern Dragoon Mountains, consists instead of primary depositional contacts within caldera-fill megabreccia, and the inferred regional thrusts do not exist, at least as previously interpreted. Silicic alkalic compositions of the Jurassic caldera-related, ash-flow tuffs; bimodal associated mafic magmatism; and interstratified coarse sedimentary deposits provide evidence for synvolcanic extension and rifting within the Cordilleran magmatic arc. Gold-copper mineralization is associated with subvolcanic intrusions at several of the Jurassic calderas.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1992)104<0032:JAFSCA>2.3.CO;2","usgsCitation":"Lipman, P.W., and Hagstrum, J., 1992, Jurassic ash-flow sheets, calderas, and related intrusions of the Cordilleran volcanic arc in southeastern Arizona: Implications for regional tectonics and ore deposits: Geological Society of America Bulletin, v. 104, no. 1, p. 32-39, https://doi.org/10.1130/0016-7606(1992)104<0032:JAFSCA>2.3.CO;2.","productDescription":"8 p.","startPage":"32","endPage":"39","numberOfPages":"8","costCenters":[],"links":[{"id":225126,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -112.33882163208548,\n              32.38295754498907\n            ],\n            [\n              -112.33882163208548,\n              31.25293988195604\n            ],\n            [\n              -108.93347953106378,\n              31.25293988195604\n            ],\n            [\n              -108.93347953106378,\n              32.38295754498907\n            ],\n            [\n              -112.33882163208548,\n              32.38295754498907\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"104","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4031e4b0c8380cd64b77","contributors":{"authors":[{"text":"Lipman, P.

T(CP) or T(1p) time constants at a contact time of 1 ms are favorable for quantification of 13C-NMR spectra. Because of the short T(CP) values, correction factors for signal intensity for various regions of the 13C-NMR spectra would be necessary at contact times greater than 1.1 ms or less than 0.9 ms. T(CP) and T(1p) values have a limited non-homogeneity within Skjervatjern fulvic and humic acids. A pulse delay or repeat time of 700 ms is more than adequate for quantification of these 13C-NMR spectra. Paramagnetic effects in these humic substances are precluded due to low inorganic ash contents, low contents of Fe, Mn, and Co, and low organic free-radical contents. The observed T(CP) values suggest that all the carbon types in Skjervatjern fulvic and humic acids are fully cross-polarized before significant proton relaxation occurs. The 13C-NMR spectra for Skjervatjern fulvic acid is similar to most aquatic fulvic acids as it is predominantly aliphatic, low in aromaticity (fa1 = 24), low in phenolic content, high in carboxyl content, and has no resolution of a methoxyl peak. The 13C-NMR spectra for Skjervatjern humic acid is also similar to most other aquatic humic acids in that it is also predominantly aliphatic, high in aromaticity (fa1 = 38), moderate in phenolic content, moderate in carboxyl content, and has a clear resolution of a methoxyl carbon region. After the consideration of the necessary 13C-NMR experimental conditions, these spectra are considered to be quantitative. With careful consideration of the previously determined 13C-NMR experimental conditions, quantitative spectra can be obtained for humic substances in the future from the HUMEX site. Possible changes in humic substances due to acidification should be determined from 13C-NMR data.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environment International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0160-4120(92)90028-3","issn":"01604120","usgsCitation":"Malcolm, R., 1992, 13C-NMR spectra and contact time experiment for Skjervatjern fulvic and humic acids: Environment International, v. 18, no. 6, p. 609-620, https://doi.org/10.1016/0160-4120(92)90028-3.","startPage":"609","endPage":"620","numberOfPages":"12","costCenters":[],"links":[{"id":499878,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/0f8d4a85779645b6b06237884da46324","text":"External Repository"},{"id":205567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0160-4120(92)90028-3"},{"id":224897,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e225e4b0c8380cd459c3","contributors":{"authors":[{"text":"Malcolm, Ronald L.","contributorId":46075,"corporation":false,"usgs":true,"family":"Malcolm","given":"Ronald L.","affiliations":[],"preferred":false,"id":374594,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The plutons form two highly distinct isotopie groups: Group I (hornblende-biotite and two-mica plutons of all ages) have Pb isotopie compositions suggesting derivation from rocks of the Belt Supergroup or their metamorphosed equivalents, although Nd isotopie data can only support this model if there was a significant input of juvenile mantle-derived or ancient light REE-depleted material. Group II (hornblende-biotite of Eocene age) have highly retarded Pb isotopie compositions relative to the present day crustal average and require a source region with long-term U (and other LIL) depletion, characteristic of cratonic lower crust. A U-Pb zircon upper intercept age of ca. 2600 Ma obtained from one of the Group II samples, together with Sm-Nd data from the gneisses, indicates possible late-Archean crust at depth, which acted as a source region for Eocene extension-related plutonism. Isotopie compositions and apparent geochemical evolution do not support a direct correlation with the nearest exposed North American Craton in the Wyoming province. If it represents attenuated pre-Mesozoic craton, then it must have been accreted to the craton prior to development of the miogeocline in the Late Proterozoic.

Air concentrations determined by alpha-track detectors (ATDs) and continuous radon monitors were compared with the predictions of a single-cell model. In many of the houses, the water supply was shown to contribute significantly to levels of indoor 222Rn. The data from the ATD study were augmented with a continuous monitoring study of a house near Lyons, CO. The well water in that house has the highest known concentration of 222Rn in water yet reported (93 MBq m-3). The temporal pattern in the indoor 222Rn concentration corresponds to water-use records. In general, it is difficult to quantify the proportion of indoor radon attributable to water use. Several lines of evidence suggest that the single-cell model underestimates this proportion. Continuous- monitoring data, although useful, are impractical due to the cost of the equipment. We propose a protocol for 222Rn measurement based on three simultaneous integrating radon detectors that may help estimate the proportion of indoor 222Rn derived from the water supply.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Health Physics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00179078","usgsCitation":"Lawrence, E., Wanty, R., and Nyberg, P., 1992, Contribution of 222Rn in domestic water supplies to 222Rn in indoor air in Colorado homes: Health Physics, v. 62, no. 2, p. 171-177.","startPage":"171","endPage":"177","numberOfPages":"7","costCenters":[],"links":[{"id":225075,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"62","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa80e4b0c8380cd4db28","contributors":{"authors":[{"text":"Lawrence, E.P.","contributorId":65129,"corporation":false,"usgs":true,"family":"Lawrence","given":"E.P.","email":"","affiliations":[],"preferred":false,"id":374329,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wanty, R.

Aqueous photolysis of solutions containing &alpha;-pinene, a representative terpene, in the presence of humic acid resulted in degradation of the pinene. Comparison of this reaction to photolysis of &alpha;-pinene in the presence of methylene blue leads to the conclusion that the reactive pathway for the abiotic degradation of &alpha;-pinene is due to reaction with singlet oxygen produced by irradiation of the humic material.

Plagioclase is one of the most common mineral phases in volcanic rocks; thus, these procedures will be widely applicable to many problems for which precise radiometric age control has not been available. We studied plagioclase and plagioclase-sanidine concentrates from the oldest and the three largest silicic ash-flow deposits of the Taupo Volcanic Zone, New Zealand, one of the world's largest and most active volcanic systems. The results are in close agreement with new magnetostratigraphic data, suggest that existing fission-track age determinations significantly underestimate the age of older units, and shift the inception of Taupo Volcanic Zone volcanism back to at least 1600 ka.

The observed variability in amounts and/or ratios of many metals and amounts and compositions of the organic matter appear related to the cause and degree of water-column stratification and the resulting absence/presence of dissolved O2 or H2S. High Cd, Mo, U, V, Zn and S contents, a high degree of pyritization (DOP) (0.75-0.88), and high high V (V + Ni) (0.84-0.89) indicate the presence of H2S in a strongly stratified water column. Intermediate contents of metals and S, intermediate DOP (0.67-0.75) and intermediate V (V + Ni) (054-0.82) indicate a less strongly stratified anoxic water column. Whereas, low metal contents and low V (V + Ni) (0.46-0.60) indicate a weakly stratified, dysoxic water column. High P contents at the top of the organic-matter-rich intervals within the Stark Shale Member indicate that phosphate precipitation was enhanced near the boundary between anoxic and dysoxic water compositions. Relatively abundant terrestrial organic matter in intervals deposited from the more strongly stratified H2S-bearing water column indicates a combined halocline-thermocline with the fresher near-surface water the transport mode for the terrestrial organic matter. The predominance of algal organic matter in intervals deposited from a less strongly stratified water column indicates the absence of the halocline and the presence of the more generally established thermocline. Relatively low amounts of degraded, hydrogen-poor organic matter characterize intervals deposited in a weakly stratified, dysoxic water column. The inferred variability in chemistry of the depositional environments may be related to climate variations and/or minor changes in sea level during the general phase of deeper water deposition responsible for this widespread shale member. ?? 1992.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0009-2541(92)90031-Y","issn":"00092541","usgsCitation":"Hatch, J.R., and Leventhal, J., 1992, Relationship between inferred redox potential of the depositional environment and geochemistry of the Upper Pennsylvanian (Missourian) Stark Shale Member of the Dennis Limestone, Wabaunsee County, Kansas, U.S.A.: Chemical Geology, v. 99, no. 1-3, p. 65-82, https://doi.org/10.1016/0009-2541(92)90031-Y.","startPage":"65","endPage":"82","numberOfPages":"18","costCenters":[],"links":[{"id":266065,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0009-2541(92)90031-Y"},{"id":225092,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a732e4b0e8fec6cdc3f1","contributors":{"authors":[{"text":"Hatch, J.

Extraterrestrial sources have been invoked in some cases (e.g., the Cambrian of China). However, available data on abundances of PGE indicate relatively low values for Ir (<0.02-2 ppb) in comparison with amounts for other PGE (up to 700 ppb Pt and 1255 ppb Pd). These data and high contents for Mo are not consistent with extraterrestrial sources of metals for Chinese shales and Ni-Mo-sulfide beds.

In the tectonically active part of upper Cook Inlet, the presence of stratigraphic sections containing numerous prehistoric interbedded layers of peat and silt suggests that such stratigraphy resulted when marshes and forests were similarly inundated and buried by intertidal and tidal sediment as a result of great, prehistoric earthquakes.</p><p>This study tests the feasibility of using buried, radiocarbon-dated, late Holocene peat layers that are exposed in the intertidal zone of upper Cook Inlet to determine earthquake recurrence intervals, because estimates of the recurrence intervals of past earthquakes are needed for evaluation of the potential for future earthquakes. In a reconnaissance study of interbedded peat and silt, 65 conventional radiocarbon dates from peat and other organic material in 25 measured sections in the intertidal zone and one drillhole were used. Radiocarbon ages from the tops of peat beds cluster weakly but may indicate that regional subsidence events recurred at irregular intervals between about 200 to 800 radiocarbon yr within the past 3,200 radiocarbon yr. Conversion to calibrated ages does not alter this range substantially but may extend both ends of the age range. Coeval and correlative stratigraphy and radiocarbon data in the buried peat layers of upper Cook Inlet strongly suggest sudden, subsidence-induced layering. Because of problems associated with conventional radiocarbon dating, the complex stratigraphy of the study area, the tectonic setting, and regional changes in sea level, conclusions from the study do not permit precise identification of the timing and recurrence of paleoseismic events.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1992)104<0684:UORDSI>2.3.CO;2","usgsCitation":"Bartsch-Winkler, S., and Schmoll, H., 1992, Utility of radiocarbon-dated stratigraphy in determining late Holocene earthquake recurrence intervals, upper Cook Inlet region, Alaska: Geological Society of America Bulletin, v. 104, no. 6, p. 684-694, https://doi.org/10.1130/0016-7606(1992)104<0684:UORDSI>2.3.CO;2.","productDescription":"11 p.","startPage":"684","endPage":"694","numberOfPages":"11","costCenters":[],"links":[{"id":224853,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"upper Cook Inlet region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.21835533891556,\n              62.26809200594323\n            ],\n            [\n              -153.26132408891561,\n              62.26809200594323\n            ],\n            [\n              -153.26132408891561,\n              59.88911950060532\n            ],\n            [\n              -149.21835533891556,\n              59.88911950060532\n            ],\n            [\n              -149.21835533891556,\n              62.26809200594323\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"104","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc0d0e4b08c986b32a32d","contributors":{"authors":[{"text":"Bartsch-Winkler, S.","contributorId":31388,"corporation":false,"usgs":true,"family":"Bartsch-Winkler","given":"S.","affiliations":[],"preferred":false,"id":374592,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmoll, H.

Three widely applied numerical models of two-dimensional transport partially account for the effects of transient flow by removing terms corresponding to the fluid continuity equation from the transport equation, resulting in a simpler governing equation. However, fluid-storage terms remaining in the transport equation that change during transient flow are, in certain cases, held constant in time in these models. For the case of increasing heads, this approximation, which is unacknowledged in these models' documentation, leads to transport velocities that are too high, and increased concentration at fluid and solute sources. If heads are dropping in time, computed transport velocities are too low. Using parameters that somewhat exaggerate the effects of this approximation, an example numerical simulation indicates solute travel time error of about 14 percent but only minor errors due to incorrect dilution volume. For horizontal flow and transport models that assume fluid density is constant, the product of porosity and aquifer thickness changes in time: initial porosity times initial thickness plus the change in head times the storage coefficient. This formula reduces to the saturated thickness in unconfined aquifers if porosity is assumed to be constant and equal to specific yield. The computational cost of this more accurate representation is insignificant and is easily incorporated in numerical models of solute transport.","language":"English","publisher":"NGWA","doi":"10.1111/j.1745-6584.1992.tb01798.x","issn":"0017467X","usgsCitation":"Goode, D., 1992, Modeling transport in transient ground-water flow: An unacknowledged approximation: Ground Water, v. 30, no. 2, p. 257-261, https://doi.org/10.1111/j.1745-6584.1992.tb01798.x.","productDescription":"5 p.","startPage":"257","endPage":"261","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":224507,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"2","noUsgsAuthors":false,"publicationDate":"2005-08-04","publicationStatus":"PW","scienceBaseUri":"505a5c58e4b0c8380cd6fc00","contributors":{"authors":[{"text":"Goode, Daniel J. 0000-0002-8527-2456 djgoode@usgs.gov","orcid":"https://orcid.org/0000-0002-8527-2456","contributorId":2433,"corporation":false,"usgs":true,"family":"Goode","given":"Daniel J.","email":"djgoode@usgs.gov","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":false,"id":374369,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Emphasis is given to results of experimental studies of V chemistry, especially those for which the experimental conditions are near those found in nature. Where possible, data are obtained for or corrected to the reference conditions of 298.15K, 1 atm (1.01325 bar) and zero ionic strength. Vanadium [IV] (V<sup>IV</sup>) and vanadium[V] (V<sup>V</sup>) are the most soluble forms of V in nature, and their complexes with fluoride, sulfate, and oxalate may act to increase V solubility under oxidizing conditions.</p><p>Because redox behavior is of fundamental importance to understanding natural V chemistry, the kinetics of reduction of V<sup>IV</sup><span>&nbsp;</span>to V<sup>III</sup><span>&nbsp;</span>H<sub>2</sub>S were studied. Although H<sub>2</sub>S is predicted from thermodynamic data to be capable of reducing V<sup>IV</sup><span>&nbsp;</span>to V<sup>III</sup>, this reaction has not been demonstrated experimentally. Experiments were carried out under conditions of temperature (45°C), pH (3.6–6.8), ionic strength (0.05–0.1 m), and V concentrations (9.8–240 μmolar) likely to be found in nature. Because the reaction is very slow, H<sub>2</sub>S concentrations in excess of natural conditions were used (8.1 × 10<sup>−4</sup><span>&nbsp;</span>to 0.41 atm). The results show that V<sup>IV</sup><span>&nbsp;</span>is reduced to V<sup>III</sup><span>&nbsp;</span>under a variety of conditions. The rate increases with increasing pH, but is not appreciably affected by ionic strength (as represented by the concentration of KCl, which was used as the supporting electrolyte in all cases). Prior to initiation of the reaction, there is an induction period, the length of which increases with increasing KCl concentration or decreasing pH. Attempts to model the reaction mechanism by numerical methods have failed to produce a satisfying fit of the results, indicating partial reaction orders, a complex mechanism, or involvement of a variety of intermediate species.</p><p>The results of the thermodynamic and kinetic studies were applied to understanding the genesis of V deposits such as those commonly found on the Colorado Plateau. Vanadium in these sandstone-hosted deposits is present mostly in the reduced oxidation state, V<sup>III</sup>. Because of the insolubility of V<sup>III</sup><span>&nbsp;</span>oxyhydroxides, it is likely that a more oxidized form of V (either [IV] or [V]) was transported to the site of mineralization, and that the V was reduced<span>&nbsp;</span><i>in situ</i><span>&nbsp;</span>and subsequently precipitated. A probable reductant is hydrogen sulfide; the presence of pyrite cogenetic with the V minerals documents the presence of H<sub>2</sub>S during mineralization. The experiments described here show that H<sub>2</sub>S could have reduced V<sup>IV</sup><span>&nbsp;</span>to V<span>&nbsp;</span><sup>III</sup>, and thus led to the formation of these deposits.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(92)90217-7","issn":"00167037","usgsCitation":"Wanty, R., and Goldhaber, M., 1992, Thermodynamics and kinetics of reactions involving vanadium in natural systems: Accumulation of vanadium in sedimentary rocks: Geochimica et Cosmochimica Acta, v. 56, no. 4, p. 1471-1483, https://doi.org/10.1016/0016-7037(92)90217-7.","productDescription":"13 p.","startPage":"1471","endPage":"1483","numberOfPages":"13","costCenters":[],"links":[{"id":224506,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"56","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb27de4b08c986b325830","contributors":{"authors":[{"text":"Wanty, R.
