In the upper Pololu Volcanics the lavas become more enriched in incompatible elements, and there is a transition from tholeiitic to alkalic basalt. In contrast, the Hawi volcanics consist of hawaiites, mugearites, and trachytes. 87Sr/86Sr ratios of 14 Pololu basalts and 5 Hawi lavas range from 0.70366 to 0.70392 and 0.70350 to 0.70355, respectively. This small but distinct difference in Sr isotopic composition of different lava types, especially the lower 87Sr/86Sr in the younger lavas with higher Rb/Sr, has been found at other Hawaiian volcanoes. Our data do not confirm previous data indicating Sr isotopic homogeneity among lavas from Kohala Volcano. Also some abundance trends, such as MgO-P2O5, are not consistent with a simple genetic relationship between Pololu and Hawi lavas. We conclude that all Kohala lavas were not produced by equilibrium partial melting of a compositionally homogeneous source. ?? 1987 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00518033","issn":"00107999","usgsCitation":"Lanphere, M.A., and Frey, F., 1987, Geochemical evolution of Kohala Volcano, Hawaii: Contributions to Mineralogy and Petrology, v. 95, no. 1, p. 100-113, https://doi.org/10.1007/BF00518033.","startPage":"100","endPage":"113","numberOfPages":"14","costCenters":[],"links":[{"id":205422,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00518033"},{"id":223857,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"95","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1636e4b0c8380cd550bd","contributors":{"authors":[{"text":"Lanphere, M.

Of the size fractions investigated (&lt;2, &lt;16, &lt;63and&lt;125 μm), the strongest correlation with trace elements occurs with the percent &lt;63 μm or&lt;125 μm fractions. As the proportion of these size fractions increases in the samples, so do the trace element concentrations. When surface area (as defined by nitrogen adsorption and the BET equations) increases, trace element levels also increase. Correlations between bulk sediment chemistry and surface area are as strong as those between sediment chemistry and the proportion of the &lt;63or&lt;125 μm fractions. Surface area appears to serve as a proxy for grain size. The strongest correlations between grain size and surface area are the same as for trace elements and grain size (with the &lt;63or&lt;125 μm fractions). Surface area also is affected by geochemical phase, as are the trace elements associated with sediments. Of the phases considered (carbonates, Mn oxides, reactive Fe, amorphous Fe, organic matter), amorphous Fe oxides appear to exert the greatest control over both surface area and trace element levels. The concentrations of various geochemical phases affect surface area, grain size, and trace element chemistry. However, the effect of phase is grain-size dependent. For material with mean grain sizes in the fine sand range and coarser (&gt; 125 μm), each of the various phases contribute to overall sample surface area. For material having mean grain sizes in the very fine sand range and finer (&lt;125 μm), the same phases act as surface-area inhibitors by cementing fine grains together to form aggregates. This increases the mean grain size of the sample and reduces the surface area. The presence of these aggregates may explain why the &lt;63 μm or&lt;125 μm size fractions are more important to sediment-trace element levels and surface area than other finer fractions.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0883-2927(87)90027-8","issn":"08832927","usgsCitation":"Horowitz, A.J., and Elrick, K.A., 1987, The relation of stream sediment surface area, grain size and composition to trace element chemistry: Applied Geochemistry, v. 2, no. 4, p. 437-451, https://doi.org/10.1016/0883-2927(87)90027-8.","productDescription":"15 p.","startPage":"437","endPage":"451","numberOfPages":"15","costCenters":[],"links":[{"id":223863,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baf0fe4b08c986b32450f","contributors":{"authors":[{"text":"Horowitz, A.

Most of the deposits are economically of low grade and genetically of xenothermal or epithermal character. Their gold- and silver-bearing minerals are usually disseminated, fine grained, and difficult to study. Sparsely disseminated pyrite and arsenoprite are common associates. Identified silver minerals are: native silver and electrum; the sulfides acanthite, argentite (the latter always inverted to acanthite), and members of the Silberkies group; the sulfosalts matildite, miargyrite, pyrargyrite, argentian tetrahedrite, and unnamed Ag-Sb-S and Ag-Fe-Sb-S minerals; the telluride hessite and the selenide naumannite; halides of the cerargyrite group; and the antimonate stetefeldtite. Suspected silver minerals include the sulfide uytenbogaardtite and the sulfosalts andorite, diaphorite, and polybasite. Electrum, acanthite, and argentian tetrahedrite are common, though nowhere abundant. The other silver minerals are rare. Silver is present as a minor element in the structure of some varieties of other minerals. These include arsenopyrite, chalcopyrite, chalcostibite, covelline, digenite, galena, sphalerite, and stibnite. The search for adventitious Ag in most of these minerals has been cursory. The results merely indicate that elemental silver is not confined to discrete silver minerals and is, therefore, an additional complication for the recovery of silver-bearing material from some deposits. Silver occurs cryptically in some plants of the region. At Red Mountain, for example, the ashed sapwood of Douglas-fir (Pseudotsuga menziesii) contains 2 to 300 ppm Ag. Silver in the ashed wood is roughly 100 times as abundant as it is in soil. The phenomenon, useful in biogeochemical exploration, deserves the attention of mineralogists. ?? 1987 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01163257","issn":"09300708","usgsCitation":"Leonard, B.F., and Christian, R., 1987, Residence of silver in mineral deposits of the Thunder Mountain caldera complex, Central Idaho, U.S.A.: Mineralogy and Petrology, v. 36, no. 3-4, p. 151-168, https://doi.org/10.1007/BF01163257.","startPage":"151","endPage":"168","numberOfPages":"18","costCenters":[],"links":[{"id":205405,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01163257"},{"id":223702,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa96fe4b0c8380cd85dc3","contributors":{"authors":[{"text":"Leonard, B.

Samples exposed in the rural location were chemically indistinguishable from the freshly quarried limestone, whereas all samples collected from urban exposure sites developed gypsum stains on the ground-facing surfaces where the stones were not washed by precipitation. The gas-solid reaction of SO//2 with calcite was selected for detailed consideration. It appears from the model that under arid conditions, the quantity of stain deposited on an unwashed surface is independent of atmospheric SO//2 concentration once the surface has been saturated with gypsum. Under wet conditions, surface sulfation and weight loss are probably dominated by mechanisms involving wet stone. However, if the rain events are frequent and delimited by periods of dryness, the quantity of gypsum produced by a gas-solid reaction mechanism should correlate with both the frequency of rain events and the atmospheric SO//2 level.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Materials Performance","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00941492","usgsCitation":"Mossotti, V.G., Lindsay, J.R., and Hochella, M.F., 1987, EFFECT OF AN ACID RAIN ENVIRONMENT ON LIMESTONE SURFACES.: Materials Performance, v. 26, no. 11, p. 47-52.","startPage":"47","endPage":"52","numberOfPages":"6","costCenters":[],"links":[{"id":225941,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0456e4b0c8380cd508fb","contributors":{"authors":[{"text":"Mossotti, Victor G. mossotti@usgs.gov","contributorId":3494,"corporation":false,"usgs":true,"family":"Mossotti","given":"Victor","email":"mossotti@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":367723,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lindsay, James R.","contributorId":19714,"corporation":false,"usgs":true,"family":"Lindsay","given":"James","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":367725,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hochella, Michael F.

Here we present detailed data on rainfall, ground-water flow, and repetitive seasonal motion that occurred from 1982 to 1985 at Minor Creek landslide in northwestern California, and we interpret these data in the context of physically based theories. We find that landslide motion is closely regulated by the direction and magnitude of near-surface hydraulic gradients and by waves of pore pressure caused by intermittent rainfall.</p><p>Diffusive propagation of pore-pressure waves accompanies downward ground-water flow along nearly vertical hydraulic gradients that exist in most of the landslide. Field data combined with a pore-pressure diffusion analysis show that single rainstorms typically produce short-period waves that attenuate before reaching the landslide base.

Earthquake data and tectonic modeling for subduction zones indicate that the slab pull force is much larger than the ridge push force. Interactions between the forces that drive and resist plate motions cause spatially and temporally localized stresses that lead to characteristic earthquake activity, providing details on how subduction occurs. Compression is localized across a locked interface thrust zone, because both the ridge push and the slab pull forces are resisted there. The slab pull force increases with increasing plate age; thus because the slab pull force tends to bend subducted plate downward and decrease the force acting normal to the interface thrust zone, the characteristic maximum earthquake at a given interface thrust zone is inversely related to the age of the subducted plate. The 1960 Chile earthquake (</span><i>M<sub>w</sub></i><span> 9.5), the largest earthquake to occur in historic times, began its rupture at an interface bounding oceanic plate &lt;30 m.y. old. However, this rupture initiation was associated with the locally oldest subducting lithosphere (weakest coupling); the rupture propagated southward along an interface bounding progressively younger oceanic lithosphere, terminating near the subducting Chile Rise. Prior to a great subduction earthquake, the sinking subducted slab will cause increased tension at depths of 50–200 km, with greatest tension near the shallow zone resisting plate subduction. Plate sinking not only leads to compressional stresses at a locked interface thrust zone but may load compressional stresses at plate depths of 260–350 km, provided that the shallow sinking occurs faster than the relaxation time of the deeper mantle. This explains K. Mogi's observations of </span><i>M</i><span> ≥ 7 thrust earthquakes at depths of 260–350 km, immediately downdip and within 3 years prior to five great, shallow earthquakes of northern Japan. The slab pull model explains the lower layer of double seismic zones as due to tension from the deeper, sinking plate and the upper layer as due to localized in-plate compression, as plate motion is resisted by the bounding mantle. Just downdip of the interface thrust zone, there occurs an aseismic 20°–50° dip increase of subducted plate. This slab bend reflects the summed slab pull force of deeper plate and probably is at the crustal basalt to eclogite phase change. Resistance to subduction provided by a continually developing slab bend may be an important factor in the size of slab pull force delivered to an interface thrust zone.</span></p>","language":"English","publisher":"Wiley","doi":"10.1029/RG025i001p00055","issn":"87551209","usgsCitation":"Spence, W., 1987, Slab pull and the seismotectonics of subducting lithosphere: Reviews of Geophysics, v. 25, no. 1, p. 55-69, https://doi.org/10.1029/RG025i001p00055.","productDescription":"15 p.","startPage":"55","endPage":"69","costCenters":[],"links":[{"id":480092,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://zenodo.org/record/1231450","text":"External Repository"},{"id":225368,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-06-14","publicationStatus":"PW","scienceBaseUri":"505b912de4b08c986b31979f","contributors":{"authors":[{"text":"Spence, William","contributorId":27454,"corporation":false,"usgs":true,"family":"Spence","given":"William","affiliations":[],"preferred":false,"id":367929,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

An Arrhenius plot of data from induced conodont color alteration by pyrolysis in air at 1 atm was used to generate the geologic temperatures for conodont color-alteration indices (CAI) above 300 °C, that is, for CAI values of 5½ through 8. Such CAI values occur in very low- to medium-grade, regionally metamorphosed, contact-metamorphosed, and hydrothermally altered rocks. The uniformity or variability of CAI values within a sample, together with conodont texture, can help to distinguish grades and environments of metamorphism, particularly in metacarbonate sequences. Induced CAI by pyrolysis in a water-methane mixture at ½ kbar results in retardation of CAI and in a disparate mixture of both low and high CAI values within each experimental sample. In this system, color-alteration processes, above a CAI of 2 to 3, seem to change from predominantly carbonization to predominantly loss of organic matter, presumably by oxidation and volatilization of oxides. These experiments approximate the type of CAI mixture characteristically found in conodonts recovered from hydrothermally altered rocks. These data indicate that CAI values of 6 to 8 cannot be used to assess precise temperatures of hydrothermally altered rocks but may serve as useful indicators of potential mineralization.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1987)99<471:CCATAA>2.0.CO;2","usgsCitation":"Rejebian, V., Harris, A., and Huebner, J., 1987, Conodont color and textural alteration: An index to regional metamorphism, contact metamorphism, and hydrothermal alteration: Geological Society of America Bulletin, v. 99, no. 4, p. 471-479, https://doi.org/10.1130/0016-7606(1987)99<471:CCATAA>2.0.CO;2.","productDescription":"9 p.","startPage":"471","endPage":"479","numberOfPages":"9","costCenters":[],"links":[{"id":225565,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f9d1e4b0c8380cd4d7c8","contributors":{"authors":[{"text":"Rejebian, V.A.","contributorId":15352,"corporation":false,"usgs":true,"family":"Rejebian","given":"V.A.","email":"","affiliations":[],"preferred":false,"id":367969,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harris, A.

Application of the partial digestion technique has proven superior to total digestion because the concentration of metals in hydromorphic compounds and the sulfides is enhanced relative to the metals bound in the unattacked silicate phases.

Since that time, the name has been applied to numerous members of the smectite group of clay minerals, although the reported chromium content has ranged from 1% to about 30% Cr<sub>2</sub>O<sub>3</sub>. The name has also been applied to some chromian chlorites. Because volkonskoite has been used for materials that differ not only in their chromium content but also in their basic structure, the species status of the mineral has been unclear.</p><p>To resolve this uncertainty, two specimens of volkonskoite from (1) Mount Efimiatsk, the type locality in the Soviet Union (USNM 16308) and (2) the Okhansk region in the Perm Basin, U.S.S.R. (USNM R4820), were examined by several mineralogical techniques.

X-ray powder diffraction patterns of both samples have broad lines corresponding to minerals of the smectite group.</p><p>On the basis of these data, volkonskoite appears to be a dioctahedral member of the smectite group that contains chromium as the dominant cation in the octahedral layer. Smectites containing less than this amount of octahedral chromium should not be called volkonskoite, but should be named by chemical element adjectives, e.g., chromian montmorillonite, chromian nontronite.</p>","language":"English","publisher":"The Clay Mineral Society","doi":"10.1346/CCMN.1987.0350206","usgsCitation":"Foord, E.E., Starkey, H.C., Taggart, J.E., and Shawe, D., 1987, Reassessment of the volkonskoite-chromian smectite nomenclature problem.: Clays and Clay Minerals, v. 35, no. 2, p. 139-149, https://doi.org/10.1346/CCMN.1987.0350206.","productDescription":"10 p.","startPage":"139","endPage":"149","costCenters":[],"links":[{"id":225762,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"2","noUsgsAuthors":false,"publicationDate":"2024-04-02","publicationStatus":"PW","scienceBaseUri":"505a95c4e4b0c8380cd81c0b","contributors":{"authors":[{"text":"Foord, Eugene E.","contributorId":96319,"corporation":false,"usgs":true,"family":"Foord","given":"Eugene","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":367995,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Starkey, Harry C.","contributorId":175349,"corporation":false,"usgs":false,"family":"Starkey","given":"Harry","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":367993,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Taggart, Joseph E.

Oxidized nitrogen inputs comparable to results of other studies were recorded during the 19 rainstorms sampled. Oxidized nitrogen concentrations appeared to increase after rainfall interacted with the pine and hardwood canopies and were inversely related to both rainfall and throughfall depth. Oxidized N concentrations in streamflow were greatest during the rising limb of storm flow with subsequent decreases during the falling limb of storm hydrographs and lowest during base flow. The oxidized N inputs from bulk precipitation were considerably greater than outputs from streamflow resulting in a net retention of oxidized nitrogen within the watershed during the study period.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.1987.tb00857.x","issn":"00431370","usgsCitation":"Lawrence, S.J., and Wigington, P.J., 1987, Oxidized Nitrogen in Precipitation, Throughfall, and Streamfall from a Forested Watershed in Oklahoma: Water Resources Bulletin, v. 23, no. 6, p. 1069-1076, https://doi.org/10.1111/j.1752-1688.1987.tb00857.x.","startPage":"1069","endPage":"1076","numberOfPages":"8","costCenters":[],"links":[{"id":267765,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.1987.tb00857.x"},{"id":225764,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"505a6a1fe4b0c8380cd73fef","contributors":{"authors":[{"text":"Lawrence, Stephen J. slawrenc@usgs.gov","contributorId":1885,"corporation":false,"usgs":true,"family":"Lawrence","given":"Stephen","email":"slawrenc@usgs.gov","middleInitial":"J.","affiliations":[{"id":316,"text":"Georgia Water Science Center","active":true,"usgs":true}],"preferred":true,"id":367997,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wigington, Parker J.
