This paper provides major, trace, and some Sr isotope data on postglacial (&lt;10000 y) rocks, i.e., tholeiitic magmas of the Eastern Rift Zone and transitional basalts, icelandites, and rhyolites of the Torfajökull centre, and assesses the relationships between the magma types in terms of the development of the Icelandic crust.Tholeiitic magmas from the Eastern Rift Zone are LILE-enriched relative to MORB. They have undergone extensive olivine-plagioclase-clinopyroxene fractionation at low pressures. Compared with the tholeiites, Torfajökull transitional basalts show LILE/HFS enrichment and higher (</span><sup>87</sup><span>Sr/</span><sup>86</sup><span>Sr)</span><sub>1</sub><span>&nbsp;ratios. They define several magmatic lineages and have equilibrated over a wide range of pressures. Both basalt types were derived by very small degrees of partial melting of compositionally similar mantle sources, the main difference being that the tholeiites were generated in the spinel Iherzolite, and the transitional basalts in the garnet lherzolite, stability fields, a conclusion previously reached by Meyer et al. (1985). The mantle sources may have contained LILE-enriched streaks.Low-pressure differentiation of Torfajökull transitional basalt produced an iceiandite to sub-alkaline rhyolite sequence by crystal fractionation, the rhyolites representing &gt;90% crystallization of parental basalts. The rhyolites were emplaced as nine separate lava fields, formed during 11 eruptive episodes. The compositional range within each field is limited, and, although similar, the ranges define several magmatic lineages. Continued fractionation of plagioclase-alkali feldspar-clinopyroxene-magnetite-apatite-zircon assemblages generated peralkaline rhyolites in certain post-glacial eruptions. Chemical variations in the deposits from the Hrafntinnusker peralkaline eruption were related predominantly to alkali feldspar fractionation, and the melts were erupted from a zoned magma chamber. All postglacial volcanic rocks at Torfajokull have been mantle derived and thus represent new additions to the Icelandic crust. © 1990 Oxford University Press.</span></p>","language":"English","publisher":"Oxford University Press","doi":"10.1093/petrology/31.2.429","issn":"00223530","usgsCitation":"Macdonald, R., Mcgarvie, D., Pinkerton, H., Smith, R.L., and Palacz, A., 1990, Petrogenetic evolution of the torfajökull volcanic complex, Iceland I. relationship between the magma types: Journal of Petrology, v. 31, no. 2, p. 429-459, https://doi.org/10.1093/petrology/31.2.429.","productDescription":"31 p.","startPage":"429","endPage":"459","costCenters":[],"links":[{"id":369767,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Iceland ","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-14.5087,66.45589],[-14.73964,65.80875],[-13.60973,65.12667],[-14.90983,64.36408],[-17.79444,63.67875],[-18.65625,63.49638],[-19.97275,63.64363],[-22.76297,63.96018],[-21.77848,64.40212],[-23.95504,64.89113],[-22.1844,65.08497],[-22.22742,65.37859],[-24.32618,65.61119],[-23.65051,66.26252],[-22.13492,66.41047],[-20.57628,65.73211],[-19.05684,66.2766],[-17.79862,65.99385],[-16.16782,66.52679],[-14.5087,66.45589]]]},\"properties\":{\"name\":\"Iceland\"}}]}","volume":"31","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Macdonald, R.","contributorId":92402,"corporation":false,"usgs":true,"family":"Macdonald","given":"R.","affiliations":[],"preferred":false,"id":776321,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mcgarvie, D.W.","contributorId":220955,"corporation":false,"usgs":false,"family":"Mcgarvie","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":776322,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pinkerton, H.","contributorId":168630,"corporation":false,"usgs":false,"family":"Pinkerton","given":"H.","email":"","affiliations":[],"preferred":false,"id":776323,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, R.

Eruptions of complex suites of mixed and hybrid rocks have been triggered, involving tholeiites of the rift zone and transitional basalts and rhyolites of the Torfajökull centre. Three-component hybrids are an unusual feature of the activity. The distribution of various magma mixing and hybrid types is related to the periodic injection of tholeiite into a magma chamber, or chambers, where rhyolite overlies parental transitional basalts.Pre-postglacial rhyolites (&gt;10000 y) at Torfajokull are predominantly peralkaline, whereas later rhyolites are, with few exceptions, subalkaline. Furthermore, the injection of rift zone magmas, and the consequent abundance of rhyolite-basalt mixing, have been important features of magmatism at the centre only in postglacial times. Reduced repose times in the magma reservoirs have prevented the production of peralkaline rhyolites. These trends are interpreted in terms of the southerly migration of the Eastern Rift Zone. © 1990 Oxford University Press.</span></p>","language":"English","publisher":"Oxford University Press ","doi":"10.1093/petrology/31.2.461","issn":" 00223530","usgsCitation":"Mcgarvie, D., Macdonald, R., Pinkerton, H., and Smith, R., 1990, Petrogenetic evolution of the torfajökull volcanic complex, Iceland II.

The Western Energy Citation Clearinghouse (WECC v.1.0), part of a suite of data and information management tools developed and managed by the Wyoming Landscape Conservation Initiative (WLCI), provides resource managers with a searchable online database of citations that covers a broad spectrum of energy and landscape related topics relevant to resource managers, such as energy sources, natural and human landscape effects, and new research, methods and models. Based on the 2011 USGS Open-file Report \"Abbreviated bibliography on energy development\" (Montag, et al. 2011), WECC is an extensive collection of energy-related citations, as well as categorized lists of additional online resources related to oil and gas development, best practices, energy companies and Federal agencies. WECC incorporates the powerful web services of Sciencebase 2.0, the enterprise data and information platform for USGS scientists and partners, to provide secure, role-based data management features. For example, public/unauthenticated WECC users have full search and read access to the entire energy citation collection, while authenticated WLCI data stewards can manage WECC's citation collection using Sciencebase data management forms.","largerWorkTitle":"Proceedings of the American Geophysical Union, Tenth Annual Hydrology Days","conferenceTitle":"Proceedings of the American Geophysical Union, Tenth Annual Hydrology Days","conferenceDate":"1990-04-10T00:00:00","conferenceLocation":"Fort Collins, CO","language":"English","publisher":"Hydrology Days Publications","publisherLocation":"Fort Collins, CO","usgsCitation":"Milhous, R.T., 1990, The quantification of instream flow rights to water, 14 p.","productDescription":"14 p.","numberOfPages":"14","costCenters":[],"links":[{"id":293742,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5412b9c1e4b0239f1986bb21","contributors":{"authors":[{"text":"Milhous, Robert T.","contributorId":28646,"corporation":false,"usgs":true,"family":"Milhous","given":"Robert","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":500746,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These observations are as follows: (1) Earthquakes in the major fault zones are predominantly deep (maximum, 22 km; characteristic, 11–18 km). (2) Earthquakes in the crustal blocks bounding the fault zones are predominantly shallow (maximum, 17 km; characteristic, 1–6 km). (3) In the San Jacinto fault zone, maximum earthquake depths correlate with surface heat flow. These relations together with focal mechanisms, geodetic strain measurements, and fault zone models are consistent with the following ideas: (1) Interseismic plate motion is accommodated by aseismic slip along an extension of the major fault zone below a brittle zone that is locked between large earthquakes. (2) The aseismic slip in a narrow fault zone in the brittle-plastic transition region concentrates strain at the base of the brittle fault zone. (3) Deep earthquakes occur in the lower part of the brittle fault zone due to stick-slip failure of highly stressed patches. (4) Background earthquakes and aftershocks that occur several kilometers deeper than large earthquake hypocenters suggest that a zone of mixed slip behavior may exist between the stable sliding (deep) and stick-slip (shallow) regions of the fault zone. This zone of mixed slip may fail predominantly by stable sliding, analogous to the central San Andreas and Calaveras faults of California. Seismic precursors to large earthquakes may occur in this zone, and large earthquakes may nucleate near the upper edge of this zone. Furthermore, the difference in seismicity between the San Jacinto and southern San Andreas faults suggests that the nature of this mixed zone may evolve as total displacement in the fault zone increases. (5) Shear stress may be less in the crustal blocks than in the deep brittle fault zones and generally at a level sufficient to cause brittle failure only shallow in the crustal blocks. (6) In the stress field produced by plate motion and slip in the deep fault zone, the upper brittle fault zone is not oriented favorably for shear failure. Lack of shallow earthquakes in the fault zones and the predominance of shallow earthquakes on favorably oriented fractures in the adjacent crustal blocks suggest that either stress in the upper brittle fault zone is relatively low or the upper fault zone is effectively strong due to its orientation.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB095iB04p04751","usgsCitation":"Sanders, C.O., 1990, Earthquake depths and the relation to strain accumulation and stress near strike-slip faults in southern California: Journal of Geophysical Research, v. 95, no.

A total of 32,400 discriminant analyses were conducted, based on data from simulated populations with appropriate underlying statistical distributions. Simulation results indicated strong bias in correct classification rates when group sample sizes were small and when overlap among groups was high. We also found that stability of the correct classification rates was influenced by these factors, indicating that the number of samples required for a given level of precision increases with the amount of overlap among groups. In a review of 60 published studies, we found that 57% of the articles presented results on classification rates, though few of them mentioned potential biases in their results. Wildlife researchers should choose the total number of samples per group to be at least 2 times the number of variables to be measured when overlap among groups is low.

Mean annual survival rates for adult males and females were significantly associated with mean banding latitude (P &lt; 0.0001 and P &lt; 0.0004, respectively) and time period (P &lt; 0.0001 and P &lt; 0.001, respectively). Survival rates for both adult males and females were higher in the north and lower in the south. Because individuals from the northern regions migrate farther, the cost of migration in terms of survival was lower than some other factor(s) that may cause the gradient. The relationship between mean banding latitude and mean annual recovery rates was marginally significant for adult males (P = 0.043) but not for adult females (P = 0.183), suggesting that the gradient was not due to differential harvest pressure.

The sites were instrumented with electronic piezometers and displacement meters to record induced pore pressures and movements of the slopes during failure. Piezometer records show a consistent trend of increasing pressure during the early stages of infiltration and abrupt decreases in pressure from 5 to 50 minutes before failure. Displacement meters failed to register the amount of movement, due to location and ineffectual coupling of meter pins to soil. Observations during the experiments indicate that fractures and macropores controlled the flow of water through the slope and that both water-flow paths and permeability within the slopes were not

The site is MacDougal Crater in the Sierra del Pinacate Reserve, Sonora, Mexico. Three sources of data have been used: a series of exactly matched photographs, begun in 1907; detailed permanent—plot maps, dating from 1959—1960; and an age—distribution analysis of a 170—yr—old population of Carnegiea gigantea. The crater vegetation is dominated by the woody perennials Cercidium microphyllum, Encelia farinosa, Prosopis sp., and Larrea tridentata, and the columnar cactus Carnegiea gigantea. Various populations of Larrea tridentata declined 50—90%, and Cercidium declined 60%, during the first half of this century with little or no recruitment since. Carnegiea numbers increased fourfold over the same period. A 200—fold increase in Prosopis in the playa—like crater center occurred in the early 1970s. Elsewhere on the crater floor, Encelia density increased markedly during the same period from insignificant levels in the early 1960s. Age distribution analysis for the Carnegiea population reveals three major establishment peaks during the 1790 period. Recruitment and morality records from the three sources of data are compared with regional climate records. The high mortality for some of the species was probably the result of the prolonged drought during 1936—1964. Establishment surges for some appear related to periods of unusually heavy precipitation during certain seasons. Clearly, desert communities are highly responsive to changes in the climate regime under which they grow.</span></p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.2307/1940301","usgsCitation":"Turner, R., 1990, Long-term vegetation change at a fully protected Sonoran Desert site: Ecology, v. 71, no. 2, p. 464-477, https://doi.org/10.2307/1940301.","productDescription":"14 p.","startPage":"464","endPage":"477","numberOfPages":"14","costCenters":[],"links":[{"id":223558,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico","state":"Sonora","otherGeospatial":"MacDougal Crater, Sierra del Pinacate Reserve","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -113.63660909726968,\n              31.984767065523613\n            ],\n            [\n              -113.63660909726968,\n              31.96736017802877\n            ],\n            [\n              -113.61785155346885,\n              31.96736017802877\n            ],\n            [\n              -113.61785155346885,\n              31.984767065523613\n            ],\n            [\n              -113.63660909726968,\n              31.984767065523613\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"71","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a49b0e4b0c8380cd687f3","contributors":{"authors":[{"text":"Turner, Raymond M.","contributorId":7383,"corporation":false,"usgs":true,"family":"Turner","given":"Raymond M.","affiliations":[],"preferred":false,"id":372906,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
