It provides exposures of gneisses (Dunbar Gneiss) that structurally underlie the voluminous metavolcanic rocks of northeastern Wisconsin, and exposures of abundant granitoid rocks ranging from tonalite to granite. The granitoid rocks cut both the gneisses in the core and the supracrustal (cover) metavolcanic rocks and were emplaced essentially along the core-cover boundary. The Dunbar Gneiss is calc-alkaline and was derived from volcanic and intrusive rocks of intermediate composition. The various intrusive rocks have calcic, calc-alkaline, and alkali to alkali-calcic compositions, and they progress with time to more SiO<sub>2</sub><span>&nbsp;</span>and K<sub>2</sub>-rich compositions. U-Pb zircon ages indicate that accumulation of the layered rocks in the core and cover, deformation and metamorphism, and intrusion of the granitoid rocks spanned a relatively short time, ∼1865–1835 Ma.</p><p>We interpret the dome as being a large-scale, fold-interference structure resulting from polydeformation modified by diapirism. Northeast-oriented folds (F<sub>3</sub>) and a related mylonitic foliation (S<sub>3</sub>), nearly confined to the dome, are superposed on northwest-oriented folds (F<sub>2</sub>) that developed during regional deformation. In the core-cover boundary, these structures are obliterated by a zone of intense deformation—a mylonitic foliation and a steeply plunging stretching lineation—as much as 500 m wide, which we interpret as resulting from diapirism. Metamorphic zoning is concentric: amphibolite facies in inner parts of the mantle and greenschist facies in the outer part of the mantle.</p><p>The Wisconsin magmatic terrane, as represented by the rocks in the Dunbar dome, differs from the epicratonic, early Proterozoic sedimentary-volcanic sequence (Marquette Range Supergroup) in Michigan, to the north, in stratigraphy, structure, and volume and composition of igneous rocks. Whereas the basalts in northern Michigan are compositionally similar to continental rift basalts, the volcanic rocks in the Dunbar dome have over-all island-arc compositional affinities. The over-all calc-alkaline compositions of the intrusive rocks are similar to those in magmatic arcs formed at convergent plate-margin settings. Accordingly, we interpret the Wisconsin magmatic terrane as an oceanic-arc complex that was sutured to the North American continent during development of the Penokean orogen. Similar interpretations based on broad regional observations have been proposed previously.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1985)96<1101:TDGDIF>2.0.CO;2","usgsCitation":"Sims, P., Peterman, Z.E., and Schulz, K.J., 1985, The Dunbar Gneiss-granitoid dome: Implications for early Proterozoic tectonic evolution of northern Wisconsin: Geological Society of America Bulletin, v. 96, no. 9, p. 1101-1112, https://doi.org/10.1130/0016-7606(1985)96<1101:TDGDIF>2.0.CO;2.","productDescription":"12 p.","startPage":"1101","endPage":"1112","numberOfPages":"12","costCenters":[],"links":[{"id":222129,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Michigan, Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -90.17501031586968,\n              44.73567155837759\n            ],\n            [\n              -86.92305719086939,\n              44.73567155837759\n            ],\n            [\n              -86.92305719086939,\n              47.35804575064864\n            ],\n            [\n              -90.17501031586968,\n              47.35804575064864\n            ],\n            [\n              -90.17501031586968,\n              44.73567155837759\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"96","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba70be4b08c986b321333","contributors":{"authors":[{"text":"Sims, P.K.","contributorId":30191,"corporation":false,"usgs":true,"family":"Sims","given":"P.K.","email":"","affiliations":[],"preferred":false,"id":363127,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterman, Z.

Samples of rocks ranging from 5 to 10 g are crushed and sieved under controlled conditions and then ground with distilled water to submicron size in a closed mechanical mill. After ultra-centrifugation, chloride content is determined by coulometric titration. The chloride concentrations and total pore-water concentrations, obtained earlier from the same pore-water concentrations, obtained earlier from the same samples by low-temperature vacuum desiccation, are used to arrive at the \"original\" pore-water chloride concentrations by a simple iteration procedure.

This activity has persisted for hundreds of thousands of years and is likely to continue. The Long Valley magma chamber had a volume approaching 3000 km</span><sup>3</sup><span>&nbsp;prior to its climatic caldera-forming eruption 0.7 m.y. ago but has been reduced to less than a third of this volume by cooling, eruption, and crystallization. Seismic evidence indicates that the main mass of the present Long Valley magma chamber is about 10 km in diameter and that its roof is 8–10 km deep with smaller cupolas as shallow as 4–5 km. Although a chamber of this size is probably capable of producing an eruption approaching 30 km</span><sup>3</sup><span>&nbsp;of lava, the record over the past 0.5 m.y. suggests that eruptions of 1 km</span><sup>3</sup><span>&nbsp;or less are far more likely. Models proposed for the current ground uplift and seismicity within the caldera require inflation of 0.1–0.2 km</span><sup>3</sup><span>&nbsp;by additional magma since mid-1979, and some models suggest that inflation was accompanied by injection of a thin dike or dikes (probably of silicic magma) into the ring fracture zone beneath the south moat. Several of the&nbsp;</span><i>M</i><span>&nbsp;5.8–6.2 earthquakes that occurred in the region beginning in 1978 had non-double-couple focal mechanisms. Whether these unusual mechanisms indicate injection of mafic (low-viscosity) magma at midcrustal depths in the Sierra Nevada block south of the caldera remains debatable. Studies of calderas of various ages throughout the world indicate that episodes of unrest are relatively common and do not invariably culminate in eruptions. Although current unrest is concentrated in the south moat of Long Valley caldera, the Inyo/Mono Craters probably hold a greater potential for producing an eruption in the foreseeable future. The Inyo/Mono Craters have erupted at 500-year intervals over the past 2000–3000 years, whereas the Long Valley magma chamber has erupted at about 200,000-year intervals over the past 700,000 years. In either case, a major earthquake near the caldera could strongly influence the course of volcanic activity.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB090iB13p11111","issn":"01480227","usgsCitation":"Hill, D., Bailey, R., and Ryall, A., 1985, Active tectonic and magmatic processes beneath Long Valley Caldera, eastern California: An overview: Journal of Geophysical Research Solid Earth, v. 90, no.

The Umpqua Formation (as herein restricted) consists of as much as 10,000 ft (3,000 m) of mudstone, sandstone, and conglomerate of nonmarine to deep marine origin. A basaltic basement that underlies the sedimentary rocks in most of the area and was formerly included in the Umpqua is herein considered a separate unit and assigned to the Siletz River Volcanics. A proposal to subdivide the Umpqua into three unconformity-bounded formations (in ascending order: Roseburg, Lookingglass, and Flournoy Formations) in the area west of Roseburg, Oregon, is not recognized in this report because of quest onable correlations and limited extent of some units. Foremost of these questionable correlations is that of the Flournoy Formation with rocks formerly assigned to the Tyee Formation in areas as far north as the latitude of Salem, Oregon. My investigations of depositional facies and lithologic criteria do not substantiate this correlation.</p><p>The Tyee Formation, which conformably overlies the Umpqua, is a predominantly sandstone unit about 6,000 ft (1,800 m) thick, deposited in environments ranging from shallow marine and nonmarine deltaic on the south, to slope and deep marine basinal to the north. Deposition across the Umpqua-Tyee boundary contact represents a change in tectonic setting from active plate margin of the Umpqua to more stable marginal basin deposition of the Tyee. This change is also reflected in a change in provenance as indicated by the characteristic arkosic and micaceous aspects of Tyee sandstones.</p>","language":"English","publisher":"American Association of Petroleum Geologists","doi":"10.1306/AD462BB9-16F7-11D7-8645000102C1865D","usgsCitation":"Molenaar, C.M., 1985, Depositional Relations of Umpqua and Tyee Formations (Eocene), Southwestern Oregon: American Association of Petroleum Geologists Bulletin, v. 69, no. 8, p. 1217-1229, https://doi.org/10.1306/AD462BB9-16F7-11D7-8645000102C1865D.","productDescription":"13 p.","startPage":"1217","endPage":"1229","numberOfPages":"13","costCenters":[],"links":[{"id":222494,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","otherGeospatial":"Umpqua and Tyee Formations","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -124.61573884056492,\n              44.09401586800607\n            ],\n            [\n              -124.61573884056492,\n              42.38533872872969\n            ],\n            [\n              -121.9551006063869,\n              42.38533872872969\n            ],\n            [\n              -121.9551006063869,\n              44.09401586800607\n            ],\n            [\n              -124.61573884056492,\n              44.09401586800607\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"69","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fd40e4b0c8380cd4e705","contributors":{"authors":[{"text":"Molenaar, C.

Both sites are characterized by high rates of sedimentation, and the organic carbon contents of these sediments generally exceed 0.5%. Anomalous seismic reflections that transgress sedimentary structures and parallel the seafloor, suggested the presence of gas hydrates at both sites, and, during coring, small samples of gas hydrate were recovered at subbottom depths of 238m (Site 533) and 404 m (Site 568). The principal gaseous components of the gas hydrates wer methane, ethane, and CO2. Residual methane in sediments at both sites usually exceeded 10 mll-1 of wet sediment. Carbon isotopic compositions of methane, CO2, and ??CO2 followed parallel trends with depth, suggesting that methane formed mainly as a result of biological reduction of oxidized carbon. Salinity of pore waters decreased with depth, a likely result of gas hydrate formation.

The method is particularly applicable when analyzing data from arrays in which most of the recording stations are far (i.e., several focal depths) from a group of events. This iterative scheme locates earthquakes relative to a master event and performs an inversion for in situ velocity using a generalized inverseleast squares estimation procedure. Direct arrivals, when available, may be included to stabilize the inversion and increase the accuracy of the event locations. We tested this scheme on artificial data contaminated by random and systematic arrival time errors, gaps in azimuthal coverage, and inaccuracies in the assumed velocity model.

The bathymetry of the lake has evolved as a result of sedimentary infilling. The western caldera is steep-sided and contains a large flat-floored central basin 240 m deep. The smaller, older, eastern caldera is mostly filled by coalescing delta fans and is connected with the larger caldera by means of a deep channel. Seismicreflection data indicate that at least 170 m of flat-lying unfaulted sediments partly fill the central basin and that the strata of the pre-eruption edifice have collapsed partly along inward-dipping ring faults and partly by more chaotic collapses. These sediments have accumulated in the last 23,000 years at a minimum average sedimentation rate of 7 m/103 yr. The upper 9 m of these sediments is composed of > 50% turbidites, interbedded with laminated clayey silts containing separate diatom and ash layers. The bottom sediments have >1% organic material, an average of 4% pyrite, and abundant biogenic gas, all of which demonstrate that the bottom sediments are anoxic. Although thin (<0.5 cm) ash horizons are common, only one thick (7-16 cm) primary ash horizon could be identified in piston cores. Alterations in the mineralogy and variations in the diatom assemblage suggest magnesium-rich hydrothermal activity. ?? 1985.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Poppe, L., Paull, C.K., Newhall, C.G., Bradbury, J., and Ziagos, J., 1985, A geophysical and geological study of Laguna de Ayarza, a Guatemalan caldera lake: Journal of Volcanology and Geothermal Research, v. 25, no. 1-2, p. 125-144.","startPage":"125","endPage":"144","numberOfPages":"20","costCenters":[],"links":[{"id":222158,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e406e4b0c8380cd46360","contributors":{"authors":[{"text":"Poppe, L.

The network had previously been surveyed in 1982. Deformation apparently associated with the Round Valley earthquake was detected as well as deformation due to the expansion of a magma chamber 8 km beneath the resurgent dome in the Long Valley caldera and right-lateral slip on the uppermost 2 km of the 1983 rupture surface in the south moat of the caldera. The deformation associated with Round Valley earthquake suggests left-lateral slip on the north-northeasterly striking vertical plane defined by the aftershock hypocenters located by A. S. Ryall. The earthquake moment implied by the deformation is about 3.8·1017 N-m, a value equivalent to an earthquake magnitude ML = 5.7 in good agreement with the observed magnitude of 5.8. A 0.053 km3 expansion of the magma chamber and 0.32 m slip on the 1983 rupture surface in the 1982-1985 interval was also required to account for the observed deformation.</p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0750051339","issn":"00371106","usgsCitation":"Gross, W., and Savage, J., 1985, Deformation near the epicenter of the 1984 Round Valley, California, earthquake: Bulletin of the Seismological Society of America, v. 75, no. 5, p. 1339-1347, https://doi.org/10.1785/BSSA0750051339.","productDescription":"9 p.","startPage":"1339","endPage":"1347","numberOfPages":"9","costCenters":[],"links":[{"id":222273,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -119.69181066830575,\n              38.329582929845884\n            ],\n            [\n              -119.69181066830575,\n              36.968318424256864\n            ],\n            [\n              -117.54398351986816,\n              36.968318424256864\n            ],\n            [\n              -117.54398351986816,\n              38.329582929845884\n            ],\n            [\n              -119.69181066830575,\n              38.329582929845884\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"75","issue":"5","noUsgsAuthors":false,"publicationDate":"1985-10-01","publicationStatus":"PW","scienceBaseUri":"5059fd3fe4b0c8380cd4e6f8","contributors":{"authors":[{"text":"Gross, W.K.","contributorId":12624,"corporation":false,"usgs":true,"family":"Gross","given":"W.K.","email":"","affiliations":[],"preferred":false,"id":364358,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Savage, J.C. 0000-0002-5114-7673","orcid":"https://orcid.org/0000-0002-5114-7673","contributorId":102876,"corporation":false,"usgs":true,"family":"Savage","given":"J.C.","affiliations":[],"preferred":false,"id":364359,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Coseismic steps were observed by creepmeters along a 200-km section of the San Andreas. some of the larger aftershocks induced additional steps, both right-lateral and left-lateral, and in general the sequence disrupted observed creep at several sites from preseismic long-term patterns. Static dislocation models can approximately explain the magnitudes and distribution of the larger coseismic steps on May 2. The smaller, more distant steps appear to be the abrupt release of accumulated slip, triggered by the coseismic strain changes, but independent of the strain change amplitudes.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0750020475","issn":"00371106","usgsCitation":"Mavko, G.M., Schulz, S., and Brown, B.D., 1985, Effects of the 1983 Coalinga, California, earthquake on creep along the San Andreas fault: Bulletin of the Seismological Society of America, v. 75, no. 2, p. 475-489, https://doi.org/10.1785/BSSA0750020475.","productDescription":"15 p.","startPage":"475","endPage":"489","numberOfPages":"15","costCenters":[],"links":[{"id":222548,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":410995,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.geoscienceworld.org/ssa/bssa/article/75/2/475/118685/Effects-of-the-1983-Coalinga-California-earthquake","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","city":"Coalinga","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.54473876953125,\n              35.98245135784044\n            ],\n            [\n              -120.12176513671875,\n              35.98245135784044\n            ],\n            [\n              -120.12176513671875,\n              36.28192129773192\n            ],\n            [\n              -120.54473876953125,\n              36.28192129773192\n            ],\n            [\n              -120.54473876953125,\n              35.98245135784044\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"75","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a045be4b0c8380cd5092b","contributors":{"authors":[{"text":"Mavko, Gerald M.","contributorId":40477,"corporation":false,"usgs":true,"family":"Mavko","given":"Gerald","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":364226,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schulz, Sandra","contributorId":107701,"corporation":false,"usgs":true,"family":"Schulz","given":"Sandra","affiliations":[],"preferred":false,"id":364228,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Beth D.","contributorId":97770,"corporation":false,"usgs":true,"family":"Brown","given":"Beth","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":364227,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
