A series of four magnitude -6 earthquakes in May 1980 called attention to this current episode of unrest, and subsequent activity has included numerous earthquake swarms in the south moat of the caldera accompanied by inflation of the resurgent dome by more than 50 cm over the last five years. The seismicity associated with this unrest is currently monitored by a network of 31 telemetered seismic stations with an automatic processing system that yelds hypocentral locations and earthquake magnitudes in near-real time. Deformation of the ground is monitored by a) a series of overlapping trilateration networks that provide coverage ranging from annual measurements of regional deformation to daily measurements of deformation local to the active, southern section of the caldera, b) a regional network of level lines surveyed annually, c) a regional network of precise gravity stations occupied annually, d) local, L-shaped level figures surveyed every few months, and e) a network of fourteen borehole tiltmeter clusters (two instruments in each cluster) and a borehole dilatometer, the telemetered signals from which provide continuous data on deformation rates. Additional telemetered data provide continuous information on fluctuations in the local magnetic field, hydrogen gas emission rates at three sites, and water level and temperatures in three wells. Continuous data on disharge rates and temperatures from hot springs and fumaroles are collected by several on-site recorders within the caldera, and samples for liquid and gas chemistry are collected several times per year from selected hot springs and fumaroles. ?? 1984 Intern.

During this period, two types of ground-shaking hazard maps have been constructed. The first type assumes that, except for scaling differences, approximately the same effects that occurred in historic earthquakes will occur in future earthquakes. The second type integrates historic seismicity data and geologic information and uses probabilistic concepts to estimate the characteristics of future ground shaking within specific exposure times. Construction of zoning maps on both a national and regional scale requires innovative research and good data to resolve technical issues about seismicity, the earthquake source, seismic wave attenuation, and local ground response.

By far the most common process is volcanic - basically the glass is rapidly chilled molten rock. All natural glasses are thermodynamically unstable and tend to alter chemically or to crystallize. The rate of these processes is determined by the chemical composition of the magma. The hot and fluid basaltic melts have a structure that allows for rapid crystal growth, and seldom forms glass selvages greater than a few centimeters thick, even when the melt is rapidly cooled by extrusion in the deep sea. In contrast the cooler and very viscous rhyolitic magmas can yield bodies of glass that are tens of meters thick. These highly polymerized magmas have a high silica content - often 71-77% SiO2. Their high viscosity inhibits diffusive crystal growth. Basalt glass in sea water forms an alteration zone called palagonite whose thickness increases linearly with time. The rate of diffusion of water into rhyolitic glass, which follows the relationship - thickness = k (time) 1 2, has been determined as a function of the glass composition and temperature. Increased SiO2 increases the rate, whereas increased CaO, MgO and H2O decrease the rate. The activation energy of water diffusion varies from about 19 to 22 kcal/mol. for the glasses studied. The diffusion of alkali out of rhyolite glass occurs simultaneously with water diffusion into the glass. The rate of devitrification of rhyolitic glass is a function of the glass viscosity, which in turn is a function of water content and temperature. Although all of the aforementioned processes tend to destroy natural glasses, the slow rates of these processes, particularly for rhyolitic glass, has allowed samples of glass to persist for 60 million years. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Non-Crystalline Solids","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00223093","usgsCitation":"Friedman, I., and Long, W., 1984, Volcanic glasses, their origins and alteration processes: Journal of Non-Crystalline Solids, v. 67, no. 1-3, p. 127-133.","startPage":"127","endPage":"133","numberOfPages":"7","costCenters":[],"links":[{"id":225921,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc2ede4b08c986b32ae5b","contributors":{"authors":[{"text":"Friedman, I.","contributorId":95596,"corporation":false,"usgs":true,"family":"Friedman","given":"I.","email":"","affiliations":[],"preferred":false,"id":367115,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Long, W.","contributorId":59963,"corporation":false,"usgs":true,"family":"Long","given":"W.","email":"","affiliations":[],"preferred":false,"id":367114,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

An intensive study of the chemistry of atmospheric deposition, soil leachate, and stream water and fish populations was conducted on these basins during 1980&ndash;1981 with emphasis on dormant season periods with runoff from snowmelt and rain. Although bedrock geology was found to control the natural buffering capacity of these streams, only acid precipitation could be linked to sharp drops in pH and increases in total Al concentrations observed during stormflows in the poorly buffered streams. Three poorly buffered streams exhibited drops to pH 4.4 to 4.5 and increases in total Al concentrations up to 1.5 mg/L during observed peak flows. Mineral soil leachate from the three major soil series on the basins during this time exhibited a low pH of 4.3 and mean total Al concentrations of 3.6 mg/L, indicating stream response during storms was closely linked to chemistry of soil leachate. Poorly buffered streams did not support reproducing populations of trout (</span><i>Salmonidae</i><span>&nbsp;sp.) or other fishes. In contrast, one well-buffered stream (20 mg/L CaCO</span><sub>3</sub><span>) exhibited drops to pH 5.5 during peak flow and supported reproducing trout and sculpin (</span><i>Cottus bairdi</i><span>) populations. The acidification of the four streams studied was attributed to atmospheric deposition.</span></p>","language":"English","publisher":"ACSESS","doi":"10.2134/jeq1984.00472425001300040022x","usgsCitation":"Sharpe, W.E., DeWalle, D.R., Leibfried, R.T., Dinicola, R., Kimmel, W.G., and Sherwin, L.S., 1984, Causes of acidification of four streams on Laurel Hilld in southwestern Pennsylvania: Journal of Environmental Quality, v. 13, no. 4, p. 619-631, https://doi.org/10.2134/jeq1984.00472425001300040022x.","productDescription":"13 p.","startPage":"619","endPage":"631","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":321907,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"574eb5b7e4b0ee97d51a839b","contributors":{"authors":[{"text":"Sharpe, William E.","contributorId":169553,"corporation":false,"usgs":false,"family":"Sharpe","given":"William","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":630935,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DeWalle, David R.","contributorId":23291,"corporation":false,"usgs":true,"family":"DeWalle","given":"David","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":630936,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leibfried, Robert T.","contributorId":169733,"corporation":false,"usgs":false,"family":"Leibfried","given":"Robert","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":630937,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dinicola, Richard S. 0000-0003-4222-294X dinicola@usgs.gov","orcid":"https://orcid.org/0000-0003-4222-294X","contributorId":352,"corporation":false,"usgs":true,"family":"Dinicola","given":"Richard S.","email":"dinicola@usgs.gov","affiliations":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"preferred":true,"id":630938,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kimmel, William G.","contributorId":84929,"corporation":false,"usgs":true,"family":"Kimmel","given":"William","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":630939,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sherwin, Lysle S.","contributorId":169734,"corporation":false,"usgs":false,"family":"Sherwin","given":"Lysle","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":630940,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

That disseminated gold mineralization is associated with Hg, As, and Sb is clearly demonstrated in these deposits for both fracture coatings and rock chip samples. However, the relationship is more pronounced for fracture coatings. Fracture coatings at Pinson contain an average of 3.61, 5.13, 14.37, and 3.42 times more Au, As, Sb and Hg, respectively, than adjacent rock samples. At Preble, fracture coatings contain 3.13, 9.72, 9.18, and 1.85 times more Au, As, Sb and Hg, respectively, than do adjacent rock samples. Geochemical anomalies determined from fracture coatings are thus typically more intense than those determined from rock samples for these elements. The sizes of anomalies indicated by fracture coatings are also somewhat larger, but this is less obvious. In both areas, Sb anomalies are more extensive in fracture coatings. At Preble, some Hg and Au anomalies are also more extensive in fracture coatings. In addition to halos formed by the Hg, As and Sb, high values for Au/Ag and Zn/(Fe + Mn) are closely associated with gold mineralization at the Pinson mine. The large enhancement in geochemical response afforded by fracture coatings indicates a definite potential in the search for buried disseminated gold deposits.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6742(84)90080-3","issn":"03756742","usgsCitation":"Crone, W., Larson, L., Carpenter, R., Chao, T.T., and Sanzolone, R.F., 1984, A comparison of iron oxide-rich joint coatings and rock chips as geochemical sampling media in exploration for disseminated gold deposits: Journal of Geochemical Exploration, v. 20, no. 2, p. 161-178, https://doi.org/10.1016/0375-6742(84)90080-3.","productDescription":"18 p.","startPage":"161","endPage":"178","numberOfPages":"18","costCenters":[],"links":[{"id":220466,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e35ce4b0c8380cd45fd5","contributors":{"authors":[{"text":"Crone, W.","contributorId":12977,"corporation":false,"usgs":true,"family":"Crone","given":"W.","email":"","affiliations":[],"preferred":false,"id":365488,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larson, L.T.","contributorId":61956,"corporation":false,"usgs":true,"family":"Larson","given":"L.T.","email":"","affiliations":[],"preferred":false,"id":365491,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carpenter, R.H.","contributorId":24913,"corporation":false,"usgs":true,"family":"Carpenter","given":"R.H.","email":"","affiliations":[],"preferred":false,"id":365489,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chao, T.

On the basis of this integrated suite of data the pre-Cretaceous Florida-Bahamas region can be divided into the pre-Jurassic North American plate, Jurassic marginal rift basins, and a broad Jurassic transform zone including stranded blocks of pre-Mesozoic continental crust. Major tectonic units include the Suwannee basin in northern Florida containing Paleozoic sedimentary rocks, a central Florida basement complex of Paleozoic age crystalline rock, the west Florida platform composed of stranded blocks of continental crust, the south Georgia rift containing Triassic sedimentary rocks which overlie block-faulted Suwannee basin sedimentary rocks, the Late Triassic-Jurassic age Apalachicola rift basin, and the Jurassic age south Florida, Bahamas, and Blake Plateau marginal rift basins. The major tectonic units are bounded by basement hinge zones and fracture zones (FZ). The basement hinge zone represents the block-faulted edge of the North American plate, separating Paleozoic and older crustal rocks from Jurassic rifted crust beneath the marginal basins. Fracture zones separate Mesozoic marginal sedimentary basins and include the Blake Spur FZ, Jacksonville FZ, Bahamas FZ, and Cuba FZ, bounding the Blake Plateau, Bahamas, south Florida, and southeastern Gulf of Mexico basins. The Bahamas FZ is the most important of all these features because its northwest extension coincides with the Gulf basin marginal fault zone, forming the southern edge of the North American plate during the Jurassic. The limited space between the North American and the South American/African plates requires that the Jurassic transform zone, connecting the Central Atlantic and the Gulf of Mexico spreading systems, was located between the Bahamas and Cuba FZ's in the region of southern Florida. Our plate reconstructions combined with chronostratigraphic and lithostratigraphic information for the Gulf of Mexico, southern Florida, and the Bahamas indicate that the gulf was sealed off from the Atlantic waters until Callovian time by an elevated Florida-Bahamas region. Restricted influx of waters started in Callovian as a plate reorganization, and increased plate separation between North America and South America/Africa produced waterways into the Gulf of Mexico from the Pacific and possibly from the Atlantic.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1029/JB089iB09p07753","usgsCitation":"Klitgord, K.D., Popenoe, P., and Schouten, H., 1984, Florida: A Jurassic transform plate boundary: Journal of Geophysical Research B: Solid Earth, v. 89, no.

Of the chemicals reviewed, all appear to present some degree of primary hazard to non-target birds and mammals; however, PA-14, the Starlicide family of chemicals and fenthion appear to be the least hazardous when used according to use directions. 4-Aminopyridine, endrin and strychnine, because of their high acute toxicity and lack of selectivity, must be considered potentially more hazardous. With respect to secondary hazards, the ranking of chemicals changes considerably and only PA-14 appears to present a negligible hazard. The Starlicide family of chemicals presents negligible hazards to most animal species under currently registered uses, but may be potentially hazardous to cats and owls under specific use conditions. Two chemicals, 4-aminopyridine and strychnine, are potentially more hazardous to predatory and scavenger animals due to their highly toxic nature and rapid lethal effects in target species, leaving unassimilated chemical in the gastrointestinal tract.

The formations are all conformable and in places intertongue and intergrade. </p><p>The major Ordovician units above the Lexington Limestone in the Blue Grass region are: The Clays Ferry Formation, the Kope Formation, the Garrard Siltstone, the Fairview Formation, the Calloway Creek Limestone, the Grant Lake Limestone, the Ashlock Formation, the Bull Fork Formation, and the Drakes Formation. The Clays Ferry Formation is made up of subequal amounts of fossiliferous limestone and shale and minor siltstone; the Clays Ferry is as much as 300 ft thick and intertongues with the Lexington Limestone and the Kope Formation. The Kope Formation resembles the partly equivalent Clays Ferry but has a higher shale content (60-80 percent) and thicker layers of shale; the Kope, as much as 275 ft thick, is mostly restricted to the northern part of the State. The Garrard Siltstone, which consists of very calcitic siltstone and minor shale, overlies the Clays Ferry Formation in the southeastern part of the Blue Grass region; the Garrard, as much as 100 ft thick, feathers out into the upper part of the Clays Ferry in southern central and northern east-central Kentucky. </p><p>The Fairview Formation is characterized by even-bedded limestone interlayered with nearly equal amounts of shale and minor siltstone. The Fairview crops out in the northern part of the Blue Grass region, where it generally overlies the Kope Formation or the Garrard Siltstone; it grades southward into the Calloway Creek Limestone. The Calloway Creek contains more limestone (generally at least 70 percent) and is more irregularly and thinner bedded than the Fairview. </p><p>The Grant Lake Limestone is composed of nodular-bedded limestone (70-90 percent), interlayered and intermixed with shale; it overlies the Fairview Formation in the northern part of the Blue Grass region and the Calloway Creek Limestone in the western and central parts. In east-central Kentucky, the Grant Lake is classified as a member of the Ashlock Formation, an assemblage of lithologically distinct units that were combined to facilitate mapping in the southeastern and southern part of the region. The Ashlock consists of the following members, in ascending order: The Tate (calcitic and dolomitic mudstone), the Grant Lake, the Gilbert (micrograined limestone and shale), the Stingy Creek (nodular-bedded mudstone and limestone), the Terrill (dolomitic and calcitic mudstone), the Sunset (micrograined limestone), and the Reba (nodular-bedded limestone and shale). </p><p>The Bull Fork Formation, which overlies the Grant Lake Limestone, is made up of subequal amounts of thin-bedded highly fossiliferous limestone and shale; limestone makes up about 80 percent of the basal part of the formation and decreases in abundance irregularly upward to only 20 percent of the top part. On the east side of the Blue Grass region, the Bull Fork grades into the Reba Member of the Ashlock Formation; on the west side, it grades into the Grant Lake. </p><p>The uppermost formation in the region is the Drakes Formation, which in east-central Kentucky consists of the Rowland Member (calcitic to dolomitic mudstone) overlain by the Preachersville Member (dolomitic to calcitic mudstone and dolomite and dolomitic siltstone). In northeast Kentucky, the Drakes is represented by only the Preachersville Member. In most of central and north-central Kentucky, the formation consists of three members: the Rowland at the base (dolomitic mudstone to muddy limestone), the Bardstown (fossiliferous limestone and shale), and the Saluda Dolomite (dolomite, in part calcitic and muddy). In northern north-central Kentucky, the Drakes is represented by only the Saluda Dolomite Member. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1151E","usgsCitation":"Weir, G.W., Peterson, W.L., Swadley, W.C., and Pojeta, J., 1984, Lithostratigraphy of Upper Ordovician strata exposed in Kentucky, with a section on biostratigraphy: U.S. Geological Survey Professional Paper 1151, v, 121 p.; 7 Plates: 37.00 x 21.00 inches or smaller, https://doi.org/10.3133/pp1151E.","productDescription":"v, 121 p.; 7 Plates: 37.00 x 21.00 inches or smaller","costCenters":[],"links":[{"id":104561,"rank":10,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_4738.htm","linkFileType":{"id":5,"text":"html"},"description":"4738"},{"id":33985,"rank":6,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33984,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33983,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33982,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33989,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1151e/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33988,"rank":9,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-7.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33987,"rank":8,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":33986,"rank":7,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1151e/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":121559,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1151e/report-thumb.jpg"}],"country":"United States","state":"Kentucky","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -83.333,\n              39.1\n            ],\n            [\n              -86,\n              39.1\n            ],\n            [\n              -86,\n              36.61568653049616\n            ],\n            [\n              -83.333,\n              36.61568653049616\n            ],\n            [\n              -83.333,\n              39.1\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635f33","contributors":{"authors":[{"text":"Weir, Gordon Whitney","contributorId":59790,"corporation":false,"usgs":true,"family":"Weir","given":"Gordon","email":"","middleInitial":"Whitney","affiliations":[],"preferred":false,"id":152854,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterson, Warren Lee","contributorId":68303,"corporation":false,"usgs":true,"family":"Peterson","given":"Warren","email":"","middleInitial":"Lee","affiliations":[],"preferred":false,"id":152855,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swadley, W.

Ratios of the nonlinear least squares to log transformation volatilization and absorption coefficients for 77 tests ranged from 0.955 to 1.08 and averaged 1.01. Comparison of the maximum, minimum, and mean root-mean-square errors of prediction for six sets of coefficients showed that the errors for the nonlinear least squares procedure were almost always smaller than the errors for the log transformation procedure.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0045-6535(84)90175-9","usgsCitation":"Rathbun, R.E., and Tai, D.Y., 1984, Comparison of nonlinear least squares and log transformation procedures for calculating volatilization coefficients: Chemosphere, v. 13, no. 7, p. 715-730, https://doi.org/10.1016/0045-6535(84)90175-9.","productDescription":"16 p.
