Silver- and bismuth-bearing galena associated with minor amounts of pyrite, chalcopyrite and sphalerite occur at the Pequea mine, Lancaster County, Pennsylvania. Ag and Bi contents in the Dandy suite of galena range from about 1.4 to 3.4 and 2.5 to 6.5 wt.% respectively, and are comparable or lower in galena from the other localities. Exsolved matildite is present in galena from the Dandy, Jackass and Leadville localities. The presence in significant amounts of both Ag and Bi in a Pb-rich sulfide system is necessary for formation of PbSss (galena solid-solution). If Ag (especially) and Bi (to a lesser extent) are absent, the galena formed will be essentially pure PbS. Some minor Sb may substitute for Bi. Compositional data for all of the galena samples are in agreement with a previously proposed linear relationship between a and Ag-Bi(Sb) content. Matildite and seven additional Pb-Bi-Ag-Cu sulfosalts have been identified from the Dandy vein system, based on electron-microprobe analyses and some X-ray powder-diffraction data.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Mineralogist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00084476","usgsCitation":"Foord, E.E., and Shawe, D., 1989, Pb-Bi-Ag-Cu-(Hg) chemistry of galena and some associated sulfosalts.

Seismic reflection profiles are too widely spaced to delineate basin boundaries accurately. Isopleths of two-way travel time representing basin fill suggest that, structurally, the basins are grabens and half-grabens. As shown on seismic reflection profiles, bounding faults of the basins intersect or merge with low-angle fault surfaces that cut the pre-Mesozoic basement. The rift basins appear to have formed by Mesozoic extension that resulted in reverse motion on reactivated basement thrust faults that originated from compressional tectonics during the Paleozoic.</div><div class=\"u-margin-s-bottom\">Computer-plotted structure contour maps derived from analysis of seismic reflection profiles provide information on the burial history of the rift basins. The postrift unconformity bevels the rift basins and, in the offshore area mapped, ranges from 2000 to 12,000 m below present sea level. The oldest postrift sediments that cover the more deeply buried rift basins are estimated to be of Middle Jurassic age (Bajocian-Bathonian), the probable time of opening of the Atlantic Ocean basin and onset of continental drift about 175–180 m.y. ago. By late Oxfordian-early Kimmeridgian time, the less deeply buried basins nearshore Delaware had been covered. A time-temperature index of maturity plot of one of the basins indicates that only dry gas would be present in reservoirs in synrift rocks buried by more than 6000 m of postrift sediments and in the oldest (Bathonian?-Callovian?) postrift rocks. Less deeply buried synrift rocks landward of the basin modeled might still be within the oil generation window.</div></div></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(89)90119-9","issn":"00253227","usgsCitation":"Benson, R., and Roberts, J., 1989, Geologic framework of the offshore region adjacent to Delaware: Marine Geology, v. 90, no. 1-2, p. 103-111, https://doi.org/10.1016/0025-3227(89)90119-9.","productDescription":"9 p.","startPage":"103","endPage":"111","numberOfPages":"9","costCenters":[],"links":[{"id":224198,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"90","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1971e4b0c8380cd559bb","contributors":{"authors":[{"text":"Benson, R.N.","contributorId":46227,"corporation":false,"usgs":true,"family":"Benson","given":"R.N.","email":"","affiliations":[],"preferred":false,"id":370704,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roberts, J.H.","contributorId":84483,"corporation":false,"usgs":true,"family":"Roberts","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":370705,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The sediments on the abyssal plain surrounding Shimada Seamount consist of pelagic clay with ferromanganese micronodules and zeolites. The pelagic clay is mostly barren of microfossils except for a few occurrences of highly corroded specimens of&nbsp;</span><i>Radiolaria</i><span>&nbsp;and diatoms. Eolian terrigenous material is the dominant component of the pelagic clay to a depth of at least 8 m below sea floor, with minor contributions from volcanic debris and hydrothermal and hydrogenous sources. The average amount of basaltic debris is only 0.25%, but concentrations are as high as 10% in some samples. The average hydrothermal component (metalliferous sediment) is 8.8% with a maximum of about 13% at 7.5 m below sea floor in one core. The hydrogenous component, mostly as ferromanganese micronodules, averages 4.1% with a maximum of 5.6%. There is no calcareous biogenic debris and essentially no siliceous biogenic debris. In the past, a decrease in hydrothermal components through time may have been the result of a decrease in relative importance of hydrothermal influences, or an increase in the flux of terrigenous debris transported by the northeast trade winds. Because volcanic activity is still active on Shimada Seamount, or has been in the recent past, the observed increase in relative abundance of terrigenous components probably was the result of increased wind transport and not decreased hydrothermal activity. Shimada Seamount may be an important local source of metalliferous sediment in the eastern equatorial North Pacific, and may have been an even more important source in the past.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(89)90235-4","issn":"00167037","usgsCitation":"Dean, W., Gardner, J., and Nancy, L.P., 1989, Influence of Shimada Seamount on sediment composition in the eastern tropical North Pacific: Geochimica et Cosmochimica Acta, v. 53, no. 7, p. 1523-1536, https://doi.org/10.1016/0016-7037(89)90235-4.","productDescription":"14 p.","startPage":"1523","endPage":"1536","numberOfPages":"14","costCenters":[],"links":[{"id":224315,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"53","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b06e4b0c8380cd6217f","contributors":{"authors":[{"text":"Dean, W.E.","contributorId":97099,"corporation":false,"usgs":true,"family":"Dean","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":371104,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gardner, J.V.","contributorId":76705,"corporation":false,"usgs":true,"family":"Gardner","given":"J.V.","affiliations":[],"preferred":false,"id":371103,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nancy, L P.","contributorId":97255,"corporation":false,"usgs":true,"family":"Nancy","given":"L","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":371105,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Numerical experiments with a detailed three-dimensional ground-water flow model indicate that significant wellbore flow can occur in contaminant monitoring wells with long well screens that are embedded in homogeneous aquifers with very small vertical head differences in the aquifer. This ``short circuiting'' of flow through boreholes should exist at some level on all scales.

Major-element compositions of both extrusive and intrusive suites in the Latir field are broadly similar; both suites include high-SiO2 rocks with low Ba and Sr, and high Rb, Nb, Th, and U contents. Moreover, both intermediateto siliciccomposition volcanic and plutonic rocks contain abundant accessory sphene and apatite, rich in rare-earth elements (REE), as well as phases in which REE's are essential components. Strong depletion in Y and REE contents, with increasing SiO2 content, in the plutonic rocks indicate a major role for accessory mineral fractionation that is not observed in volcanic rocks of equivalent composition. Considerations of the rheology of granitic magma suggest that accessory-mineral fractionation may occur primarily by filter-pressing evolved magmas from crystal-rich melts. More limited accessory-mineral crystallization and fractionation during evolution of the volcanic magmas may have resulted from markedly lower diffusivities of essential trace elements than major elements. Accessory-mineral fractionation probably becomes most significant at high crystallinities. The contrast in crystallization environments postulated for the extrusive and intrusive rocks may be common to other magmatic systems; the effects are particularly pronounced in highly evolved rocks of the Latir field. High-SiO2 peralkaline porphyry emplaced during resurgence of the Questa caldera represents non-erupted portions of the magma that produced the Amalia Tuff during caldera-forming eruption. The peralkaline porphyry continues compositional and mineralogical trends found in the tuff. Amphibole, mica, and sphene compositions suggest that the peralkaline magma evolved from metaluminous magma. Extensive feldspar fractionation occurred during evolution of the peralkaline magmas, but additional alkali and iron enrichment was likely a result of high halogen fluxes from crystallizing plutons and basaltic magmas at depth. ?? 1989 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/BF00371367","issn":"00107999","usgsCitation":"Johnson, C., Czamanske, G., and Lipman, P.W., 1989, Geochemistry of intrusive rocks associated with the Latir volcanic field, New Mexico, and contrasts between evolution of plutonic and volcanic rocks: Contributions to Mineralogy and Petrology, v. 103, no. 1, p. 90-109, https://doi.org/10.1007/BF00371367.","startPage":"90","endPage":"109","numberOfPages":"20","costCenters":[],"links":[{"id":205461,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00371367"},{"id":224250,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"103","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a16fee4b0c8380cd55344","contributors":{"authors":[{"text":"Johnson, C.M.","contributorId":78707,"corporation":false,"usgs":true,"family":"Johnson","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":370711,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Czamanske, G.K.","contributorId":26300,"corporation":false,"usgs":true,"family":"Czamanske","given":"G.K.","email":"","affiliations":[],"preferred":false,"id":370710,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lipman, P.

The samples, particularly those with calc-alkalic compositions, are rich in plagioclase that is strongly zoned; the more silicic samples contain orthopyroxene, clinopyroxene, and primary amphibole. The quartz diorite dike contains iron-rich almandine phenocrysts that appear to be magmatic, suggesting emplacement at great depth near the base of the crust or upper mantle.Chemical and mineralogical compositions are similar to those of modern Aleutian-arc lavas. They also resemble volcanic-arc compositions from western mainland Alaska, although greater chemical diversity and a stronger continental influence are observed in the Alaskan mainland rocks.Early Eocene ages of 54.4–50.2 Ma for the Beringian samples are well constrained by conventional K–Ar ages of nine plagioclase separates and by concordant&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar incremental heating and total-fusion experiments. A concordant U–Pb zircon age of 53 Ma for the quartz-diorite dike is in good agreement with the K–Ar data.Plate motion studies of the North Pacific Ocean indicate more northerly directed subduction prior to the Tertiary and a continuous belt of arc-type volcanism extending from Siberia, along the Beringian margin, into mainland Alaska. Around 56 Ma (chron 25–24), subduction changed to a more westerly direction and subduction-related volcanism ceased for most of mainland Alaska. The increasingly oblique angle of convergence should have ended subduction along the Beringian margin as well. However, consistent ages of 54–50 Ma indicate a final pulse in arc-type magmatism during this period of plate adjustment, which may be explained by three different models: (1) The northern and central part of the Beringian margin maintained a higher angle of convergence, allowing a final pulse of arc-type magmatism. (2) The rocks erupted in an early, or proto, Aleutian arc and were rafted against the continental margin along transform faults. (3) The rocks erupted along a leaky transform fault, analogous to calc-alkalic volcanism in the southern California borderland.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e89-125","issn":"00084077","usgsCitation":"Davis, A.S., Pickthorn, L., Vallier, T., and Marlow, M.S., 1989, Petrology and age of volcanic-arc rocks from the continental margin of the Bering Sea: Implications for Early Eocene relocation of plate boundaries: Canadian Journal of Earth Sciences, v. 26, no. 7, p. 1474-1490, https://doi.org/10.1139/e89-125.","productDescription":"17 p.","startPage":"1474","endPage":"1490","costCenters":[],"links":[{"id":224142,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Russia, United States","state":"Alaska","otherGeospatial":"Bering Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -197.4659960695814,\n              50.52803134071158\n            ],\n            [\n              -150.82047128460496,\n              50.52803134071158\n            ],\n            [\n              -150.82047128460496,\n              66.48242987205629\n            ],\n            [\n              -197.4659960695814,\n              66.48242987205629\n            ],\n            [\n              -197.4659960695814,\n              50.52803134071158\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"26","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7818e4b0c8380cd7862a","contributors":{"authors":[{"text":"Davis, A.

Gold grains, collected from 46 placer localities and 6 lode gold sites in the district, were analyzed for Ag and 37 trace elements utilizing direct current-arc optical emission spectroscopy. When possible, several measurements were made on each sample and averaged. Gold content was calculated by the summation of the 38 elements determined and subtracting from 100. The objectives of our study were to characterize the deposits by defining the type and number of distinct geochemical characteristics for the Au, to determine relationships of Au in placer deposits to possible lode sources (placer and lode), to identify possible primary sources of placer gold, and to study processes of placer formation. Interpretation of results emphasize that the Au grains are almost invariably ternary (Au-Ag-Cu) alloys.

From such forecasts, exploration and development costs can more readily be computed. Two classes of these forecasting models are the Arps-Roberts type models and the 'creaming method' models. This paper examines the robustness of the forecasts made by these models when the historical data on which the models are based have been subject to economic upheavals or when historical discovery data are aggregated from areas having widely differing economic structures. Model performance is examined in the context of forecasting discoveries for offshore Texas State and Federal areas. The analysis shows how the model forecasts are limited by information contained in the historical discovery data. Because the Arps-Roberts type models require more regularity in discovery sequence than the creaming models, prior information had to be introduced into the Arps-Roberts models to accommodate the influence of economic changes. The creaming methods captured the overall decline in discovery size but did not easily allow introduction of exogenous information to compensate for incomplete historical data. Moreover, the predictive log normal distribution associated with the creaming model methods appears to understate the importance of the potential contribution of small fields. ?? 1989.","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(89)90006-8","issn":"02648172","usgsCitation":"Attanasi, E.D., and Schuenemeyer, J., 1989, Robustness of disaggregate oil and gas discovery forecasting models: Marine and Petroleum Geology, v. 6, no. 3, p. 270-276, https://doi.org/10.1016/0264-8172(89)90006-8.","startPage":"270","endPage":"276","numberOfPages":"7","costCenters":[],"links":[{"id":268650,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0264-8172(89)90006-8"},{"id":223944,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aade0e4b0c8380cd86fb5","contributors":{"authors":[{"text":"Attanasi, E.

Adults maintained breeding territories that averaged 40.3 ha (</span><i>n</i><span>= 10, SE = 4.0). They returned to the same territory seasonally for up to seven consecutive years. Territorial males moved from areas of high male abundance to areas of high female abundance on a seasonal basis. During the winter, 74% of adult males left breeding areas and joined concentrations of males located near the ends of the range. Thirty percent of the subadult males were observed in male groups near the extremities of the range. During the summer and fall, the density of adult males (15/1,000 ha) and adult male to independent otter (non-pup) ratio (1:5) in female areas was highest. The number of adult males in areas of female abundance was inversely related to the number of dependent pups, perhaps because when pup numbers are low (late summer and fall) the number of estrous females is high. Subadult males may remain in female areas on a year round basis until their second or third year. However, they were not generally associated with adult females.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1748-7692.1989.tb00330.x","usgsCitation":"Jameson, R.J., 1989, Movements, home range, and territories of male sea otters off central California: Marine Mammal Science, v. 5, no. 2, p. 159-172, https://doi.org/10.1111/j.1748-7692.1989.tb00330.x.","productDescription":"14 p.","startPage":"159","endPage":"172","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130206,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"central California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.62474766910888,\n              37.607013138439115\n            ],\n            [\n              -122.62474766910888,\n              33.96067210203324\n            ],\n            [\n              -118.88321880244082,\n              33.96067210203324\n            ],\n            [\n              -118.88321880244082,\n              37.607013138439115\n            ],\n            [\n              -122.62474766910888,\n              37.607013138439115\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"5","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-08-26","publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b4847","contributors":{"authors":[{"text":"Jameson, Ronald J.","contributorId":17938,"corporation":false,"usgs":true,"family":"Jameson","given":"Ronald","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":315444,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
