The measurement of stress change depends on the reaction of a slender, compliant cavity to the transient variations of rock stress about the cavity. A liquid-filled pressurized cell, emplaced in the cavity, provides the means by which changes in pressure can be monitored. The change in pressure in the cell is equivalent to the change in rock stress in the direction normal to the cell if the compliance contrast between cavity and rock is large and the aspect ratio of the cavity is small. Earthquake-related variations in the stress field in a highly fractured quartz-monzonite stock have been observed to occur in a characteristic way prior to a microseismic event. The precursory stress change (decompression followed by compression) lasted about 5 hours and led directly to a stress drop of 15 × 10−3 bar. Seismic noise monitored during the same period of time suggests that failure in the fractured rock mass resulted from rapid encroachment of meltwater and subsequent increase in fluid pressure.</p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0800010197","usgsCitation":"Swolfs, H., and Walsh, J., 1990, The theory and prototype development of a stress-monitoring system: Bulletin of the Seismological Society of America, v. 80, no. 1, p. 197-208, https://doi.org/10.1785/BSSA0800010197.","productDescription":"12 p.","startPage":"197","endPage":"208","numberOfPages":"12","costCenters":[],"links":[{"id":422166,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.geoscienceworld.org/ssa/bssa/article/80/1/197/119326/The-theory-and-prototype-development-of-a-stress"},{"id":223235,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb0f2e4b08c986b325154","contributors":{"authors":[{"text":"Swolfs, H.S.","contributorId":70759,"corporation":false,"usgs":true,"family":"Swolfs","given":"H.S.","affiliations":[],"preferred":false,"id":372062,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walsh, J.B.","contributorId":63846,"corporation":false,"usgs":true,"family":"Walsh","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":372061,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The igneous protolith of this gneiss was a suite of subduction-related platonic rocks. U-Pb data on zircons from trondhjemitic and granitic samples yield upper-intercept (igneous) ages of 2070 ±16 and 2040 ±74 Ma, respectively. Nd isotope data from these rocks suggest that a diorite-tonalite-trondhjemite suite (ε<sub>Nd</sub><span>&nbsp;</span>[T] = +2.1 to +2.7; T is time of crystallization) evolved from partial melts of depleted mantle with no discernible contamination by older crust, whereas a coeval granitic pluton (ε<sub>Nd</sub><span>&nbsp;</span>[T] = -5.7) contains a significant component derived from Archean crust. Orthogneisses with similar age and Nd isotope characteristics are found in the Idono complex 250 km to the north. Early Proterozoic rocks are unknown elsewhere in Alaska. However, Phanerozoic plutons cutting several \"continental\" terranes in Alaska (southern Brooks Range and Ruby, Seward, and Yukon-Tanana terranes) have Nd isotope compositions indicative of Early Proterozoic (or older) crustal components that could be correlative with rocks of the Kilbuck terrane. Rocks with similar igneous ages in cratonal North America are rare, and those few that are known have Nd isotope compositions distinct from those of the Kilbuck terrane. Conversely, provinces with Nd model ages off 2.0-2.1 Ga are characterized by extensive 1.8 Ga or younger plutonism, which is unknown in the Kilbuck terrane. At present the case for a North American parentage of the Kilbuck terrane is not compelling. The possibility that the Kilbuck terrane was displaced from provinces off similar age in other cratons (e.g., Australian, Baltic, Guiana, and west African shields), or from the poorly dated Siberian craton, cannot be excluded.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1990)018<1219:KTOKRI>2.3.CO;2","issn":"00917613","usgsCitation":"Box, S.E., Moll-Stalcup, E.J., Wooden, J.L., and Bradshaw, J., 1990, Kilbuck terrane: Oldest known rocks in Alaska: Geology, v. 18, no. 12, p. 1219-1222, https://doi.org/10.1130/0091-7613(1990)018<1219:KTOKRI>2.3.CO;2.","productDescription":"4 p.","startPage":"1219","endPage":"1222","numberOfPages":"4","costCenters":[],"links":[{"id":223236,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4092e4b0c8380cd64e7a","contributors":{"authors":[{"text":"Box, S.

Three periods were evident: (1) A spring bloom, during snowmelt, of the planktonic diatom <i>Asterionella formosa</i>, (2) a mid-summer period of minimal algal abundance, and (3) a fall bloom of the blue-green alga <i>Oscillatoria limnetica</i>. Seasonal phytoplankton dynamics in these lakes are controlled partially by the rapid flushing rate during snowmelt and the transport of phytoplankton from the highest lake to the lower lakes by the stream, Icy Brook. During snowmelt, the A. formosa population in the most downstream lake has a net rate of increase of 0.34 d<sup>-1</sup>, which is calculated from the flushing rate and from the A. formosa abundance in the inflow from the upstream lake and in the downstream lake. Measurement of photosynthetic rates at different depths during the three periods confirmed the rapid growth of <i>A. formosa</i> during the spring. The decline in <i>A. formosa</i> after snowmelt may be related to grazing by developing zooplankton populations. The possible importance of the seasonal variations in nitrate concentrations were evaluated in situ enrichment experiments. For <i>A. formosa</i> and <i>O. limnetica</i> populations, growth stimulation resulted from 8- or 16-micromolar amendments of calcium nitrate and sulfuric acid, but the reason for this stimulation could not be determined from these experiments.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.2307/1551589","usgsCitation":"McKnight, D.M., Smith, R.L., Bradbury, J.P., Baron, J., and Spaulding, S.A., 1990, Phytoplankton dynamics in three Rocky Mountain lakes, Colorado, USA: Arctic and Alpine Research, v. 22, no. 3, p. 264-274, https://doi.org/10.2307/1551589.","productDescription":"11 p.","startPage":"264","endPage":"274","costCenters":[{"id":40553,"text":"WMA - Office of the Chief Operating Officer","active":true,"usgs":true}],"links":[{"id":223029,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Glass Lake, Sky Pond, The Loch","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.66053867340088,\n              40.29026356570576\n            ],\n            [\n              -105.65397262573242,\n              40.29026356570576\n            ],\n            [\n              -105.65397262573242,\n              40.294551700286306\n            ],\n            [\n              -105.66053867340088,\n              40.294551700286306\n            ],\n            [\n              -105.66053867340088,\n              40.29026356570576\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.66755533218382,\n              40.280245946971625\n            ],\n            [\n              -105.66429376602173,\n              40.280245946971625\n            ],\n            [\n              -105.66429376602173,\n              40.28315972120923\n            ],\n            [\n              -105.66755533218382,\n              40.28315972120923\n            ],\n            [\n              -105.66755533218382,\n              40.280245946971625\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.67180395126341,\n              40.27657899643966\n            ],\n            [\n              -105.66710472106934,\n              40.27657899643966\n            ],\n            [\n              -105.66710472106934,\n              40.27944381853661\n            ],\n            [\n              -105.67180395126341,\n              40.27944381853661\n            ],\n            [\n              -105.67180395126341,\n              40.27657899643966\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"22","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7b38e4b0c8380cd7930d","contributors":{"authors":[{"text":"McKnight, Diane M.","contributorId":59773,"corporation":false,"usgs":false,"family":"McKnight","given":"Diane","email":"","middleInitial":"M.","affiliations":[{"id":16833,"text":"INSTAAR, University of Colorado","active":true,"usgs":false}],"preferred":false,"id":371901,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, Richard L. 0000-0002-3829-0125 rlsmith@usgs.gov","orcid":"https://orcid.org/0000-0002-3829-0125","contributorId":1592,"corporation":false,"usgs":true,"family":"Smith","given":"Richard","email":"rlsmith@usgs.gov","middleInitial":"L.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":38175,"text":"Toxics Substances Hydrology Program","active":true,"usgs":true}],"preferred":true,"id":371903,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bradbury, J.

This observation, plus the discovery of a hibernation-induced trigger (HIT) in the blood of black bears, prompted the examination of polar bear blood collected thoughout the year for evidence ofr HIT, and to determine if it displayed opioid activity, as black bear blood does. A bioassay was conducted by injected summer 13-lined ground squirrels with serum collected from polar bears at different seasons. One group of squirrels was previously implanted with osmotic pumps containing naloxone. The rest had pumps containing saline. Squirrels with saline pumps all hibernated significantly more than those with naloxone, except the group receiving blood from a November polar bear, observed to be highly active and hyperphagic. An in vitro study, using guinea pig ileum, showed that 400 nM morphine inhibited induced contractions and 100 nM naloxone reversed the inhibition. Ten mg of winter polar bear serum albumin fraction (to which HIT binds in ground squirrels and woodchucks) had a similar inhibiting effect, but naloxone, even at 4,000 nM, didn't reverse it. It is concluded that polar bear contains HIT, that it has an opioid effct, but may not itself be an opioid.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0091-3057(90)90311-5","usgsCitation":"Bruce, D.S., Darling, N.K., Seeland, K.J., Oeltgen, P.R., Nilekani, S.P., and Amstrup, S.C., 1990, Is the polar bear (<i>Ursus maritimus</i>) a hibernator?

The geology of Mount Mazama has been mapped at a scale of 1:24,000 based on detailed study of the walls of Crater Lake caldera and mapping of the flanks of the volcano.

The lower transgressive unit includes a large linear shoal found at a water depth of 90 m and hardground mounds at water depths of 70–80 m. Some patches of earlier Pleistocene prodelta mud remain also, exposed or covered by a thin veneer of transgressive sand on the northern outer shelf.

Thermal waters in the KGRA and at Mammoth Hot Springs, located 13 km inside the Park boundary, are high in bicarbonate and sulfate and are actively depositing travertine. These similarities and the existence of numerous regional-scale structural and stratigraphic features that could provide conduits for fluid flow at depth indicate a possible cause for concern. The objectives of this study include delineations of any hydrologic connections between these thermal waters, the level of impact of geothermal development in the event of such connections, and mitigation measures to minimize or eliminate adverse impacts. The study involves a number of geochemical, geophysical, geologic, and hydrologic techniques, but does not include any test drilling. Preliminary results suggest that thermal waters at Bear Creek Springs may contain a component of water derived from Mammoth but that thermal waters at La Duke Hot Spring do not. The total rate of thermal water that discharges in the area proposed for geothermal development (near La Duke) has been determined; restricting the net production of thermal water to rates less than this total could provide a satisfactory margin of safety for development.","largerWorkTitle":"Transactions - Geothermal Resources Council","conferenceTitle":"1990 International Symposium on Geothermal Energy","conferenceDate":"20 August 1990 through 24 August 1990","conferenceLocation":"Kailua-Kona, HI, USA","language":"English","publisher":"Publ by Geothermal Resources Council","publisherLocation":"Davis, CA, United States","issn":"01935933","isbn":"0934412677","usgsCitation":"Sorey, M., Colvard, E., and Sturchio, N., 1990, Geothermal systems within the Mammoth Corridor in Yellowstone National Park and the adjacent Corwin Springs KGRA, <i>in</i> Transactions - Geothermal Resources Council, v. 14, no. pt 1, Kailua-Kona, HI, USA, 20 August 1990 through 24 August 1990, p. 729-733.","startPage":"729","endPage":"733","numberOfPages":"5","costCenters":[],"links":[{"id":223027,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"pt 1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a28dde4b0c8380cd5a4a7","contributors":{"authors":[{"text":"Sorey, Michael","contributorId":49933,"corporation":false,"usgs":true,"family":"Sorey","given":"Michael","email":"","affiliations":[],"preferred":false,"id":371897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Colvard, Elizabeth","contributorId":29135,"corporation":false,"usgs":true,"family":"Colvard","given":"Elizabeth","affiliations":[],"preferred":false,"id":371896,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sturchio, N.C.","contributorId":16580,"corporation":false,"usgs":true,"family":"Sturchio","given":"N.C.","affiliations":[],"preferred":false,"id":371895,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Analysis of three MT and two seismic refraction profiles in Oregon and a coincident MT and refraction profile in northern California show a high degree of correlation between resistivity and velocity models. The main feature that is evident in both data sets is a highly conductive (2-20 ohm m) zone that occurs at depths of 6-20 km and largely within a midcrustal velocity layer of 6.4-6.6 km/s, overlying a lower crust with velocities of 7.0-7.4 km/s. Accretionary structures in the southern Washington Cascades have been shown to be related to stress release in the area of Mount St. Helens.

Most of the country rocks are Lower Proterozoic mica schists. At 1700 Ga, intrusion of the Harney Peak Granite created a large dome in these rocks, a thermal aureole with a staurolite, a first sillimanite isograd, and a small area of metamorphism above the second sillimanite isograd. The zoned pegmatites have a strong tendency to occur in clusters, and the types of pegmatites are different in different clusters. A less obvious tendency is a regional zonation in which rare-mineral pegmatites become more abundant and muscovite pegmatites less abundant toward the outskirts of the region. The composition of the granite indicates that its magma originated by partial melting of metasedimentary mica schists similar to those at the present surface.

The magnetic and gravity maps show large amplitude positive anomalies associated with the shallow but largely buried section of Washington Coast Range mafic rocks which are separated by negative anomalies over deep sedimentary basins. The positive anomalies indicate that the Coast Range mafic basement extends farther east than previously thought, at least as far east as the longitude of Seattle. Linear and steep gravity and magnetic gradients indicate many unmapped, often buried faults in the Washington Coast Range Province. Magnetic highs are also associated with mapped batholiths in the Cascade arc. Several magnetic highs observed east of the Coast Range rocks and west of these batholiths may be associated with buried Tertiary plutons or ophiolites. Two-dimensional gravity and magnetic modeling constrained with geological and other geophysical data indicate that the Coast Range Province rocks are about 1 km thick at the coast, thickening to as much as 30 km near their postulated eastern edge. A maximum boundary on the average density of the upper 15–20 km of the rocks that compose the Coast Range Province of 2920 kg/m</span><sup>3</sup><span>&nbsp;was established by the modeling, suggesting a composition largely of basalt and gabbro with little interbedded sediments. Under these rocks may be mantle or a subduction complex composed of dense mafic, ultramafic, and sedimentary rocks like that proposed to underlie Vancouver Island.

However, my Washington model requires that the proposed subduction complex be more dense than the trench sediments and, therefore, that material denser than sediments be incorporated within it. The absence of continental mantle and the modeled wedge shape of the Coast Range Province upper crust suggest that erosion of the bottom of the overriding plate by subduction processes may have occurred.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB095iB12p19533","issn":"01480227","usgsCitation":"Finn, C.A., 1990, Geophysical constraints on Washington convergent margin structure: Journal of Geophysical Research Solid Earth, v. 95, no.

The magnetotactic bacterium contained a single chain of approximately 10 crystals aligned along the long axis of the cell. The crystals were essentially pure stoichiometric magnetite. When viewed along the crystal long axis the particles had a hexagonal cross-section whereas side-on they appeared as rectangules or truncated rectangles of average dimension, 53 × 35 nm. These findings are explained in terms of a three-dimensional morphology comprising a hexagonal prism of 110 faces which are capped and truncated by 111 end faces. Electron diffraction and lattice imaging studies indicated that the particles were structurally well-defined single crystals. In contrast, magnetite particles produced by the strain, GS-15 were irregular in shape and had smaller mean dimensions (14 nm). Single crystals were imaged but these were not of high structural perfection. These results highlight the influence of intracellular control on the crystallochemical specificity of bacterial magnetites. The characterization of these crystals is important in aiding the identification of biogenic magnetic materials in paleomagnetism and in studies of sediment magnetization.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0012-821X(90)90084-B","issn":"0012821X","usgsCitation":"Sparks, N., Mann, S., Bazylinski, D., Lovley, D.R., Jannasch, H., and Frankel, R., 1990, Structure and morphology of magnetite anaerobically-produced by a marine magnetotactic bacterium and a dissimilatory iron-reducing bacterium: Earth and Planetary Science Letters, v. 98, no. 1, p. 14-22, https://doi.org/10.1016/0012-821X(90)90084-B.","productDescription":"9 p.","startPage":"14","endPage":"22","numberOfPages":"9","costCenters":[],"links":[{"id":223102,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"98","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9c17e4b08c986b31d28e","contributors":{"authors":[{"text":"Sparks, N.H.C.","contributorId":57210,"corporation":false,"usgs":true,"family":"Sparks","given":"N.H.C.","email":"","affiliations":[],"preferred":false,"id":372967,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mann, S.","contributorId":69713,"corporation":false,"usgs":true,"family":"Mann","given":"S.","email":"","affiliations":[],"preferred":false,"id":372968,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bazylinski, D.A.","contributorId":55964,"corporation":false,"usgs":true,"family":"Bazylinski","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":372966,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lovley, Derek R.","contributorId":107852,"corporation":false,"usgs":true,"family":"Lovley","given":"Derek","middleInitial":"R.","affiliations":[],"preferred":false,"id":372971,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jannasch, H.W.","contributorId":89665,"corporation":false,"usgs":true,"family":"Jannasch","given":"H.W.","email":"","affiliations":[],"preferred":false,"id":372969,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Frankel, R.B.","contributorId":95623,"corporation":false,"usgs":true,"family":"Frankel","given":"R.B.","email":"","affiliations":[],"preferred":false,"id":372970,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Stratigraphic evidence at a number of localities, including new evidence from Crater Island on the west side of the Great Salt Lake Desert, shows that the Stansbury shoreline formed during the transgressive phase of late Pleistocene Lake bonneville (sometime between about 22,000 and 20,000 yr B.P.). Tufa-cemented gravel and barrier beaches were deposited in the Stansbury shorezone during one or more fluctuations in water level with a maximum total amplitude of 45 m. We refer to the fluctuations as the Stansbury oscillation. The Stansbury oscillation cannot have been caused by basin-hypsometric factors, such as stabilization of lake level at an external overflow threshold or by expansion into an interior subbasin, or by changes in drainage basin size. Therefore, changes in climate must have caused the lake level to reverse its general rise, to drop about 45 m in altitude (reducing its surface area by about 18%, 5000 km2), and later to resume its rise. If the sizes of Great Basin lakes are controlled by the mean position of storm tracks and the jetstream, which as recently postulated may be controlled by the size of the continental ice sheets, the Stansbury oscillation may have been caused by a shift in the jetstream during a major interstade of the Laurentide ice sheet. ?? 1990.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(90)90057-R","issn":"00335894","usgsCitation":"Oviatt, C.G., Currey, D., and Miller, D., 1990, Age and paleoclimatic significance of the Stansbury shoreline of Lake Bonneville, Northeastern Great Basin: Quaternary Research, v. 33, no. 3, p. 291-305, https://doi.org/10.1016/0033-5894(90)90057-R.","startPage":"291","endPage":"305","numberOfPages":"15","costCenters":[],"links":[{"id":222789,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266502,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(90)90057-R"}],"volume":"33","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059e8e0e4b0c8380cd47f2d","contributors":{"authors":[{"text":"Oviatt, Charles G.","contributorId":36580,"corporation":false,"usgs":false,"family":"Oviatt","given":"Charles","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":372920,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Currey, D.R.","contributorId":60775,"corporation":false,"usgs":true,"family":"Currey","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":372921,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Miller, D.

The Schoolhouse consists mainly of yellowish gray to gray, low-angle to parallel bedded, very fine to fine-grained sandstone of eolian sand-sheet origin; interbedded fluvial deposits are present in most sections. Geological and geochemical data suggest that Schoolhouse Member oils have upper Paleozoic sources, including the intrabasinal Belden Formation. Late Paleozoic faults have served as local conduits for vertical petroleum migration. Large-scale (>200 km) lateral migration from sources in the Permian Phosphoria Formation is also possible but less likely. Belden oil was generated and migrated before about 75 Ma. Subsequently, the Schoolhouse Member reservoir was uplifted, then partly exhumed on the monoclinal flank of the Laramide (latest Cretaceous-Paleogene) White River uplift. -from Authors","language":"English","publisher":"American Association of Petroleum Geologists","doi":"10.1306/0C9B2277-1710-11D7-8645000102C1865D","usgsCitation":"Johnson, S., Schenk, C.J., Anders, D.L., and Tuttle, M., 1990, Sedimentology and petroleum occurrence, Schoolhouse Member, Maroon Formation (Lower Permian), northwestern Colorado: American Association of Petroleum Geologists Bulletin, v. 74, no. 2, p. 135-150, https://doi.org/10.1306/0C9B2277-1710-11D7-8645000102C1865D.","productDescription":"16 p.","startPage":"135","endPage":"150","numberOfPages":"16","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":223557,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -109.03521561958132,\n              40.43018100909984\n            ],\n            [\n              -109.03521561958132,\n              39.149940820318875\n            ],\n            [\n              -106.07504074968867,\n              39.149940820318875\n            ],\n            [\n              -106.07504074968867,\n              40.43018100909984\n            ],\n            [\n              -109.03521561958132,\n              40.43018100909984\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"74","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8a9fe4b08c986b3172a5","contributors":{"authors":[{"text":"Johnson, Samuel Y. 0000-0001-7972-9977","orcid":"https://orcid.org/0000-0001-7972-9977","contributorId":208205,"corporation":false,"usgs":true,"family":"Johnson","given":"Samuel Y.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":372903,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schenk, Christopher J. 0000-0002-0248-7305","orcid":"https://orcid.org/0000-0002-0248-7305","contributorId":72344,"corporation":false,"usgs":true,"family":"Schenk","given":"Christopher","email":"","middleInitial":"J.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":372905,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anders, D.

Key features of the record include: 1) the mean frequency of eruptive periods during the past 4000 years is approximately two per century; however, the variance about the mean may be large; 2) at most major centres, episodes of activity lasting several thousand years are defined by groups of eruptive periods separated by apparent dormant intervals of roughly similar duration, 3) arc-wide clustering of eruptive activity may exist at 0-4 ka, 6-8 ka, and 10-14 ka. Such clustering would be remarkable in light of significant along-arc changes in crustal structure, stress field, and subduction-zone geometry. -Author","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geoscience Canada","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03150941","usgsCitation":"Scott, W.E., 1990, Patterns of volcanism in the Cascade Arc during the past 15 000 years: Geoscience Canada, v. 17, no. 3, p. 179-183.","startPage":"179","endPage":"183","numberOfPages":"5","costCenters":[],"links":[{"id":222874,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a75eee4b0c8380cd77e18","contributors":{"authors":[{"text":"Scott, W.
