The deformational events are generally characterized by distinctive structural fabrics and metamorphisms. Most of the events are interpreted to be related to subduction-related accretion or terrane accretion along the Border Ranges fault system (BRFS) and companion faults, and the Contact fault system (CFS). Each period of subduction-related accretion consisted of underplating of the outboard unit beneath the adjacent inboard unit. The fabric associated with each subduction-related accretion consisted of folding, intense shearing, and local rolling of planar structures. Age and structural relationships suggest migration of the zone of subduction-related accretion from the BRFS to the north, through each accreting unit, to younger bounding thrust faults to the south. Other older and younger deformational events are also recognized and are interpreted to have formed before and after, respectively, accretions along the BRFS and CFS. The main younger deformational events are (1) early Tertiary north verging folding of portions of the northern Chugach and southern Wrangellia terranes and (2) broad folding and rotation of major and minor structures related to subduction-related accretion or terrane accretion during early and middle Tertiary oroclinal bending of Alaska.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB094iB04p04297","issn":"01480227","usgsCitation":"Nokleberg, W., Plafker, G., Lull, J.S., Wallace, W.K., and Winkler, G.R., 1989, Structural analysis of the southern Peninsular, southern Wrangellia, and northern Chugach terranes along the Trans-Alaska Crustal Transect, northern Chugach Mountains, Alaska: Journal of Geophysical Research Solid Earth, v. 94, no.

Continuous data collection allowed estimates to be made for each component of the water-balance equation independent of other components. The average annual precipitation was 948 millimeters. Average annual evapotranspiration was estimated at 637 millimeters, runoff was 160 millimeters, change in water storage in a waste-trench cover was 24 millimeters, and deep percolation was 208 millimeters. The magnitude of the difference between precipitation and all other components (81 millimeters per year) indicates that, in a similar environment, the water-budget method would be useful in estimating evapotranspiration, but questionable for estimation of other components. Precipitation depth and temporal distribution had a very strong effect on all other components of the water-balance equation. Due to the variability of precipitation from year to year, it appears that two years of data are inadequate for characterization of the long-term average water balance at the site.","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.1752-1688.1989.tb03075.x","issn":"00431370","usgsCitation":"Healy, R.W., Gray, J.R., De Vries, G.M., and Mills, P., 1989, Water balance at a low-level radioactive-waste disposal site: Water Resources Bulletin, v. 25, no. 2, p. 381-390, https://doi.org/10.1111/j.1752-1688.1989.tb03075.x.","startPage":"381","endPage":"390","numberOfPages":"10","costCenters":[],"links":[{"id":267749,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.1989.tb03075.x"},{"id":224422,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"505bc7c1e4b08c986b32c5ec","contributors":{"authors":[{"text":"Healy, R.

Comprised of a sequence of 75 remote reference magnetic variation (MV) stations spaced 3-4 km apart, the profile stretched for 225 km from Newport, on the Oregon coast, across the Coast Range, the Willamette Valley, and the High Cascades to a point ??? 50 km east of Santiam Pass. At all of the MV stations, data were collected for short periods (16-100 s), and at 17 of these stations data were also obtained at longer periods (100-1600 s). Data were monitored with a three-component ring core fluxgate magnetometer (Nanotesla), and were recorded with a microcomputer (DEC PDP 11/73) based data acquisition system. A 2-D generalized inversion of the magnetic transfer coefficients over the period range of 16-1600 s indicates four distinct conductors. First, we see the coast effect caused by a large sedimentary wedge offshore. Second, we see the effect of currents flowing in the conductive sediments of the Willamette Valley. Our inversion suggests that the Willamette Valley consists of two electrically distinct features, due perhaps to a horst-like structure imprinted on the valley sediments. Next we note an electric current system centered beneath the High Cascades. This latter feature may be associated with a sediment-filled graben beneath Santiam Pass as suggested by some of the gravity and MT results reported to date. Finally, we detect the presence of a deep conductor at mid-crustal depths which laterally extends westward from beneath the Basin and Range Province, and terminates beneath the western Cascades. One view of this last result is that it appears that modern Basin and Range structure is being imprinted on pre-existing Cascade structure. ?? 1989.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Physics of the Earth and Planetary Interiors","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0031-9201(89)90016-2","issn":"00319201","usgsCitation":"Hermance, J., Lusi, S., Slocum, W., Neumann, G., and Green, A., 1989, A high-density remote reference magnetic variation profile in the Pacific northwest of North America: Physics of the Earth and Planetary Interiors, v. 53, no. 3-4, p. 305-319, https://doi.org/10.1016/0031-9201(89)90016-2.","startPage":"305","endPage":"319","numberOfPages":"15","costCenters":[],"links":[{"id":267325,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0031-9201(89)90016-2"},{"id":224100,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"53","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e41ee4b0c8380cd4640c","contributors":{"authors":[{"text":"Hermance, J.F.","contributorId":59565,"corporation":false,"usgs":true,"family":"Hermance","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":371192,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lusi, S.","contributorId":37903,"corporation":false,"usgs":true,"family":"Lusi","given":"S.","email":"","affiliations":[],"preferred":false,"id":371190,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Slocum, W.","contributorId":53096,"corporation":false,"usgs":true,"family":"Slocum","given":"W.","email":"","affiliations":[],"preferred":false,"id":371191,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Neumann, G.A.","contributorId":11767,"corporation":false,"usgs":true,"family":"Neumann","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":371189,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Green, A.W.

We believe that these volcanic and stratified sedimentary rocks, known by different formational names in different parts of this region, are, in fact, segments of one and the same suite of rocks that formed during the early and middle Tertiary.</p><p>The volcanic-sedimentary complex is exposed on both sides of a north-trending lowland formed by the collinear Juab and Sevier Valleys. West of the lowland, the complex has been named the \"Goldens Ranch Formation\" east of the lowland, it has been called the \"Moroni Formation.\"; Both formations are stratigraphically alike in that each consists of a lower unit composed predominantly of water-laid, variably cemented sediments and sedimentary rocks with some tuff beds near the base, and an upper unit of intermediate-composition volcanic rocks, chiefly ash-flow tuffs, and volcanic breccias. Both formations contain abundant exotic clasts of andesite, tan and purple quartzite, and dark blue limestone and dolomite. Both formations are folded and faulted along with the underlying sedimentary units.</p><p>Potassium-argon ages indicate that both the Goldens Ranch and Moroni Formations formed during the late Eocene to middle Oligocene. The geochronology and stratigraphic relations are strong evidence that the Goldens Ranch and Moroni Formations are correlative, and that they are one and the same depositional unit.</p><p>During the latest Oligocene-earliest Miocene, minor monzonitic bodies intruded sedimentary units in the area.</p><p>The new K-Ar data bear on the matter of the origin of the complex structural deformation in central Utah. Different workers have attributed the singular deformation either to recurrent episodes of compression stemming from the Sevier orogeny, or to repeated episodes of salt diapirism. We recognize two sequences of repeated deformation: one that occurred prior to deposition and consolidation of the Goldens Ranch and Moroni Formations, and a second that occurred after these formations were emplaced, in essence, after early Oligocene time. The Sevier orogeny ended in Paleocene time; thus, the compression and thrusting stemming from the Sevier orogeny could be responsible for the structural complexity that marks pre-Paleocene units. These same orogenic forces do not seem to be viable explanations for the broad flexures and monoclinal downwarps that mark the Goldens Ranch, Moroni, and younger formations. In our view, multiple episodes of salt diapirism more reasonably explain the structural complexity in central Utah.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1989)101<0534:SONPAA>2.3.CO;2","usgsCitation":"Witkind, I.J., and Marvin, R.F., 1989, Significance of new potassium-argon ages from the Goldens Ranch and Moroni Formations, Sanpete-Sevier Valley area, central Utah: Geological Society of America Bulletin, v. 101, no. 4, p. 534-548, https://doi.org/10.1130/0016-7606(1989)101<0534:SONPAA>2.3.CO;2.","productDescription":"15 p.","startPage":"534","endPage":"548","numberOfPages":"15","costCenters":[],"links":[{"id":224433,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Utah","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -112.40554338984188,\n              39.776483822588716\n            ],\n            [\n              -112.40554338984188,\n              38.91841705321613\n            ],\n            [\n              -111.26296526484207,\n              38.91841705321613\n            ],\n            [\n              -111.26296526484207,\n              39.776483822588716\n            ],\n            [\n              -112.40554338984188,\n              39.776483822588716\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"101","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8f1be4b08c986b318d24","contributors":{"authors":[{"text":"Witkind, I.

These data were collected across the Border Ranges fault system, a major suture zone that separates the Peninsular and Chugach tectonostratigraphic terranes. The Chugach terrane consists of metamorphosed, strongly deformed flysch, subduction melange as well as blueschist- and greenschist-facies rocks. Even so, highly reflective rocks lie at great depth within or beneath this terrane. The shallow part of the seismic section (0–5 s) reveals only a few reflections, which undulate and interweave, indicating that some of them originate outside of the plane of the seismic section. Other undulating events could reveal early Cenozoic granitic plutons or antiformal stacks of rock imbricated along thrust faults. In contrast to this shallow reflection pattern, three reflection bands contain most of the events on the middle part of the seismic section (5–12 s or 12–34 km). We interpret divergent reflections within the uppermost band (5–5.5 s) as gently north dipping thrust faults, and subparallel reflections truncated at the boundaries of the upper and middle bands may image a metamorphic foliation or thrust faults. If the truncated reflections represent thrust faults, then the reflection geometry suggests that subparallel roof and floor thrust faults bound imbricated rocks, forming duplex structures. The upper and middle bands are separated by an area on the seismic section that reveals few reflections. This area correlates approximately in depth with a high velocity (7.5 km/s) layer evident in refraction models. The poorly reflective, high velocity unit might be volcanic rocks like those exposed in the structurally lowest part of the Chugach terrane. If so, then the bottom of the poorly reflective rocks indicates the base of the Chugach terrane. Rocks that cause the upper and middle reflection bands and the intervening, poorly reflective volcanic rocks may form a midcrustal shear zone that is about 10 km thick. The deepest band of subparallel reflections (30–35 km) correlates closely in depth with the top of the Wadati-Benioff zone associated with the underthrusting Pacific plate. The reflections probably stem from the decollement that separates lithospheric plates within the subduction zone. This reflection band increases abruptly in thickness, possibly indicating local underplating of subducted sediment. No events from the oceanic Moho have been recognized. Neither the Border Ranges fault system, the suture between the Chugach and Peninsular terranes, nor deep crustal layers of the Peninsular terrane are evident in these seismic reflection data.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB094iB04p04424","issn":"01480227","usgsCitation":"Fisher, M.A., Brocher, T., Nokleberg, W., Plafker, G., and Smith, G., 1989, Seismic reflection images of the crust of the northern part of the Chugach terrane, Alaska: Results of a survey for the Trans-Alaska Crustal Transect (TACT): Journal of Geophysical Research Solid Earth, v. 94, no.

Observation wells were installed in the shallow aquifer of the flood plain, and water quality samples were collected to determine if contaminants are present in the shallow groundwater. Groundwater in the shallow aquifer occurs under water-table conditions. Recharge is primarily from precipitation and discharge is to East Fork Poplar Creek. Groundwater levels fluctuate seasonally in response to variations in recharge and evapotranspiration. During extremely dry periods, the water table drops below the base of the shallow aquifer in some flood-plain areas. Contaminants found in water samples from several of the wells in concentrations which equaled or exceeded drinking-water standards established by the U.S. Environmental Protection Agency are antimony, chromium, lead, mercury, selenium, phenols, and strontium-90. Total and dissolved uranium concentrations exceeded the analytical detection limit in nearly 70% of the wells in the flood plain. The results of water quality determinations demonstrate that elevated concentrations of most trace metals (and possibly organic compounds and radionuclides) were caused by contaminated sediments in the samples. The presence of contaminated sediment in samples is suspected to be the result of borehole contamination during well installation.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri884219","usgsCitation":"Carmichael, J.K., 1989, An investigation of shallow ground-water quality near East Fork Poplar Creek, Oak Ridge, Tennessee: U.S. Geological Survey Water-Resources Investigations Report 88-4219, v, 49 p., https://doi.org/10.3133/wri884219.","productDescription":"v, 49 p.","costCenters":[],"links":[{"id":123597,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_88_4219.jpg"},{"id":414497,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47116.htm","linkFileType":{"id":5,"text":"html"}},{"id":2087,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri88-4219","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Tennessee","city":"Oak Ridge","otherGeospatial":"East Fork Poplar Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -84.3,\n              36.0181\n            ],\n            [\n              -84.3,\n              35.9806\n            ],\n            [\n              -84.2444,\n              35.9806\n            ],\n            [\n              -84.2444,\n              36.0181\n            ],\n            [\n              -84.3,\n              36.0181\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db684245","contributors":{"authors":[{"text":"Carmichael, J.

In September 1987, Louisiana's first statewide beach cleanup attracted about 3300 volunteers who filled 16,000 bags with trash collected along 15 beaches. An estimated 800,173 items were gathered. Forty percent of the items were made of plastic and 11% were of polystyrene. Of all the litter collected, 37% was beverage-related. Litter from the oil and gas, commercial fishing, and maritime shipping industries was found, as well as that left by recreational users. Although beach cleanups temporarily rid Louisiana beaches of litter, the real value of the effort is in public participation and education. Civic groups, school children, and individuals have benefited by increasing their awareness of the problems of trash disposal.","largerWorkTitle":"Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management","conferenceTitle":"Coastal Zone '89: Proceedings of the Sixth Symposium on Costal and Ocean Management","conferenceDate":"11 July 1989 through 14 July 1989","conferenceLocation":"Charleston, SC, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","usgsCitation":"Lindstedt, D.M., and Holmes, J.C., 1989, Louisiana's statewide beach cleanup, <i>in</i> Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management, v. 1, no. pt1, Charleston, SC, USA, 11 July 1989 through 14 July 1989, p. 915-924.","startPage":"915","endPage":"924","numberOfPages":"10","costCenters":[],"links":[{"id":223656,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"pt1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a49fee4b0c8380cd68a3f","contributors":{"authors":[{"text":"Lindstedt, Dianne M.","contributorId":90473,"corporation":false,"usgs":true,"family":"Lindstedt","given":"Dianne","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":370765,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Holmes, Joseph C.

In the Klerksdorp district where the strata are offset by major throughgoing normal faults, the largest tremors, with magnitudes ranging as high as 5.2, tend to be associated with slip on these pre-existing faults. Moreover, the seismic source and ground motion parameters are quite similar to those of natural crustal earthquakes. In the Carletonville district, by contrast, where substantial faults do not exist, the large-magnitude tremors appear to result from the failure of relatively intact rock and cause seismic stress drops and ground motion parameters higher than normally observed for natural shocks. Additionally, there appears to be an upper magnitude limit of about 4 in the Carletonville district. Detailed analyses of an exceptionally large event recorded locally from each of these districts serve to highlight these contrasts. ?? 1989 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00874511","issn":"00334553","usgsCitation":"McGarr, A., Bicknell, J., Sembera, E., and Green, R., 1989, Analysis of exceptionally large tremors in two gold mining districts of South Africa: Pure and Applied Geophysics PAGEOPH, v. 129, no. 3-4, p. 295-307, https://doi.org/10.1007/BF00874511.","startPage":"295","endPage":"307","numberOfPages":"13","costCenters":[],"links":[{"id":223985,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205434,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00874511"}],"volume":"129","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eb12e4b0c8380cd48bcf","contributors":{"authors":[{"text":"McGarr, Art 0000-0001-9769-4093","orcid":"https://orcid.org/0000-0001-9769-4093","contributorId":43491,"corporation":false,"usgs":true,"family":"McGarr","given":"Art","affiliations":[],"preferred":false,"id":370826,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bicknell, J.","contributorId":107433,"corporation":false,"usgs":true,"family":"Bicknell","given":"J.","email":"","affiliations":[],"preferred":false,"id":370828,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sembera, E.","contributorId":7274,"corporation":false,"usgs":true,"family":"Sembera","given":"E.","email":"","affiliations":[],"preferred":false,"id":370825,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Green, R.W.E.","contributorId":68041,"corporation":false,"usgs":true,"family":"Green","given":"R.W.E.","email":"","affiliations":[],"preferred":false,"id":370827,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
