The most persistent DDT homolog (</span><i class=\"EmphasisTypeItalic \">p,p</i><span>′-DDE) continued to constitute about 70% of total DDT residues, as it did in 1974–79. DDT contamination attributable to former DDT manufacturing facilities remained evident at sites in Alabama and Arkansas, and high concentrations at one site in Hawaii suggested that input to the environment was continuing. Conversely, the data do not support the contention of others that DDT was still being used in the Southwest. Residues of polychlorinated biphenyls (PCBs) remained widespread, but a significant downward trend in total PCBs was evident, especially in areas that the NPMP has previously shown to be the most heavily contaminated. Mean concentrations of dieldrin had not changed since 1978–79, and levels remained highest in Hawaii and in the Great Lakes. Toxaphene concentrations plateaued after a period of steady increase through the 1970's, but the incidence of toxaphene continued to increase; residues were present at 88% of the stations sampled in 1980–81, including one in Alaska (most likely as a consequence of atmospheric transport).

Igneous rocks range from basalt to dacite and yielded K-Ar ages of 48 to 22 m.y. The Meshik arc is oriented along the trend of the Alaska Peninsula, subparallel to the present-day Aleutian arc. Rocks of the Meshik arc are emplaced on Cenozoic, Mesozoic, and older clastic sedimentary rocks of the Alaska Peninsula terrane. Tectonic interpretation suggests: a) the arc represents a relatively stationary period in the otherwise mobile migration of the Alaska Peninsula terrane, b) subduction was an important process along the Alaska Peninsula during Tertiary time, and c) most migration of the Alaska Peninsula terrane since Cretaceous time took place in Paleocene and middle Miocene time. </p>","language":"English","publisher":"Alaska Division of Geological & Geophysical Surveys","publisherLocation":"Fairbanks, AK","doi":"10.14509/2269","usgsCitation":"Wilson, F.H., 1985, The Meshik Arc: An eocene to earliest miocene magmatic arc on the Alaska Peninsula: Alaska Division of Geological & Geophysical Surveys Professional Reports DGGS PR 88, iii, 14 p., https://doi.org/10.14509/2269.","productDescription":"iii, 14 p.","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":480157,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.14509/2269","text":"Publisher Index Page"},{"id":341373,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Alaska Peninsula","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -166.201171875,\n              55.05320258537112\n            ],\n            [\n              -163.828125,\n              53.48804553605622\n            ],\n            [\n              -152.02880859375,\n              58.938673187948304\n            ],\n            [\n              -154.6435546875,\n              60.28340847828243\n            ],\n            [\n              -166.201171875,\n              55.05320258537112\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"591c0fcfe4b0a7fdb43ddf1c","contributors":{"authors":[{"text":"Wilson, Frederic H. 0000-0003-1761-6437 fwilson@usgs.gov","orcid":"https://orcid.org/0000-0003-1761-6437","contributorId":67174,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederic","email":"fwilson@usgs.gov","middleInitial":"H.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":695391,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The Maclaren terrane consists of the Maclaren Glacier metamorphic belt and the regionally deformed and metamorphosed East Susitna batholith. The Maclaren Glacier metamorphic belt is composed of argillite, metagraywacke, and sparse andesite flows that are progressively regionally metamorphosed from lower greenschist facies to middle amphibolite facies near the East Susitna batholith. The East Susitna batholith is composed of gabbro, quartz diorite, granodiorite, and sparse quartz monzonite. Isotopic ages are as old as a K-Ar hornblende age of 87.5 m.y., possibly reset, and a U-Pb zircon age of 70 m.y. The batholith is intensely deformed and regionally metamorphosed under conditions of the middle amphibolite facies.</p><p>The Wrangellia terrane is divided into two subterranes: (1) the Slana River subterrane, composed of late Paleozoic andesite to dacite flows, tuff, limestone, and argillite, unconformably overlying massive basalt flows of the Triassic Nikolai Greenstone, Late Triassic limestone, and younger Mesozoic flysch; and (2) the Tangle subterrane, a deeper-water equivalent of the Slana River subterrane, composed of late Paleozoic and Early Triassic aquagene tuff, chert, minor andesite tuff and flows, limestone, unconformably overlying pillow basalt and massive basalt flows of the Triassic Nikolai Greenstone, and Late Triassic limestone. Both subterranes are intruded by locally extensive gabbro and diabase dikes and by cumulate mafic and ultramafic sills.</p><p>Less extensive terranes (two) are the Clearwater terrane, a sequence of intensely deformed chlorite schist, muscovite schist, marble, and greenstone of Late Triassic age; and an unnamed terrane of ultramafic and associated rocks of presumable Paleozoic or Mesozoic age. Each terrane or subterrane generally has (1) a distinctive time-stratigraphic sequence reflecting a unique geologic history; (2) a missing provenance for bedded sedimentary or volcanic rocks; and (3) bounding thrust or strike-slip faults, interpreted as accretionary sutures.</p><p>The Maclaren and Wrangellia terranes are juxtaposed along the Broxson Gulch thrust, which consists of an imbricate series of north-dipping thrust faults. Paralleling the Broxson Gulch thrust, a few kilometres to the south, is the north-dipping Eureka Creek thrust, along which are juxtaposed the Slana River and Tangle subterranes. The Maclaren terrane is correlated with the Kluane Schist and the Ruby Range batholith in the southern Yukon Territory, which represent the northward extension of the Taku and Tracy Arm terranes. If correct, this correlation defines a minimum displacement of the Maclaren terrane along the Denali fault of ∼400 km.</p><p>The Maclaren terrane is interpreted to have formed in a synorogenic Andean-type arc setting on the west margin of Mesozoic North America in the middle to late Mesozoic and early Cenozoic. The Wrangellia terrane is interpreted to have initially formed in an island-arc setting during the late Paleozoic. Subsequently in the Late Triassic, the Wrangellia terrane underwent rifting near the paleoequator, with formation of the Nikolai Greenstone and associated mafic and ultra-mafic igneous rocks. In the middle and late Mesozoic, Wrangellia migrated toward, and was accreted during, the middle Cretaceous to the Maclaren terrane along the Broxson Gulch thrust. Subsequent dispersion of both the Maclaren and Wrangellia terranes along the Denali fault and the Broxson Gulch thrust commenced during the early Tertiary and continues through the present.</p>","language":"English","publisher":"GSA","doi":"10.1130/0016-7606(1985)96<1251:OATEOT>2.0.CO;2","usgsCitation":"Nokleberg, W.J., Jones, D.L., and Silberling, N.J., 1985, Origin and tectonic evolution of the Maclaren and Wrangellia terranes, eastern Alaska Range, Alaska: GSA Bulletin, v. 96, no. 10, p. 1251-1270, https://doi.org/10.1130/0016-7606(1985)96<1251:OATEOT>2.0.CO;2.","productDescription":"20 p.","startPage":"1251","endPage":"1270","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":375479,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Maclaren and Wrangellia terranes","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -151.962890625,\n              61.227957176677876\n            ],\n            [\n              -141.064453125,\n              61.227957176677876\n            ],\n            [\n              -141.064453125,\n              64.1297836764257\n            ],\n            [\n              -151.962890625,\n              64.1297836764257\n            ],\n            [\n              -151.962890625,\n              61.227957176677876\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"96","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Nokleberg, Warren J. 0000-0002-1574-8869 wnokleberg@usgs.gov","orcid":"https://orcid.org/0000-0002-1574-8869","contributorId":2077,"corporation":false,"usgs":true,"family":"Nokleberg","given":"Warren","email":"wnokleberg@usgs.gov","middleInitial":"J.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":790640,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, D.

The deposits, located approximately 180 km apart, are hosted by Mississippian and Pennsylvanian strata of the Kagvik structural sequence of late Paleozoic and early Mesozoic age. This sequence is situated in the lowermost structural plate of a series of predominantly east-striking, shallow-dipping thrust plates that characterize the regional structure. The deposits occur in shale, tuff, tuffaceous sandstone, altered chert, and quartz exhalite. These units are in places interlayered with or adjacent to bedded or nodular barite or submarine keratophyre flows. Chert and shale commonly contain abundant highly altered, fine-grained feldspar, pumice lapilli, and mafic volcanic rock fragments.The main types of occurrences at Red Dog Creek are: (1) disseminated and stratiform sulfides thinly bedded in organic-rich Mississippian and Pennsylvanian shale and chert, (2) massive sulfide veins and breccia fillings in silicified Mississippian and Pennsylvanian shale, and (3) stratiform sulfide-bearing lenses subdivided into (3a) quartz-exhalite with up to several percent sulfides and barite, (3b) massive sulfide-quartz lenses with up to several percent barite, and (3c) barite-quartz lenses with up to several percent sulfides.At Drenchwater Creek sulfides and barite occur as: (1) disseminations in shale, chert, tuff, and tuffaceous sandstone; (2) disseminations to aggregates in quartz exhalite; and (3) occurrences in veins crosscutting cleavages in brecciated chert and shale.The stratiform sulfides occur in zones up to several thousand meters long and several tens of meters thick. Preliminary grades at Red Dog Creek are 17.1 percent zinc, 5.0 percent lead, and 2.4 oz silver per ton contained in at least 85 million tons.The range of sulfide sulfur isotope values at Red Dog Creek is -16.6 per mil to +3.6 per mil. Sphalerite averages 0.8 per mil. Pyrite is isotopically lighter than coexisting sphalerite in quartz exhalite and massive sulfide lenses. This isotopic relationship is compatible with paragenetic relationships which show pyrite crystallized both earlier and later than other sulfides. Galena is isotopically lighter than coexisting sphalerite. Three groups of geologically and isotopically distinct barites exist including isotopic values appropriate for derivation from late Paleozoic seawater sulfate.Early in the depositional sequence isotopically light pyrite formed from organically reduced seawater sulfate. Sphalerite, galena, late pyrite, and some barite precipitated from two sulfur-bearing solutions that mixed at the mineralization site. Isotopically light barite associated with sulfides precipitated from oxidized H&nbsp;</span><sub>2</sub><span>&nbsp;S without seawater sulfate contribution. Lead isotope data from Red Dog and Drenchwater Creeks are compatible with generation of lead in a Phanerozoic mature island-arc setting, a typical orogene, or possibly a back-arc type intracratonic basin.The stratiform sphalerite-galena-barite deposits probably formed in an incipient island-arc environment near a continental margin, containing magmas of keratophyric and andesitic composition, where metal-laden hydrothermal fluids discharged into a deep (?) water, low-energy environment.

Most of these plutons crop out south of the Denali fault system (DFS) in the Talkeetna quadrangle. Plutons of the McKinley sequence largely intrude deformed upper Meszoic flysch between the DFS and the northern edges of Wrangellia and the Peninsular terrane, which jointly make up the Talkeetna superterrane. The average K-Ar age of biotite from nine granites of the McKinley sequence is 57.3 Ma; Rb-Sr data for whole rock samples indicate that the McKinley sequence cannot be older than 60 Ma. A selected suite of 20 samples of granite and granodiorite range in SiO</span><sub>2</sub><span>&nbsp;from 65.9 to 77.6%. All 20 samples are corundum normative, and 18 are moderately peraluminous.

These high and variable Sr isotopic ratios, peraluminous nature, rare earth element patterns, and high σ</span><sup>18</sup><span>O values suggest that granitic rocks of the McKinley sequence crystallized from hybrid magmas produced by assimilation of sedimentary rocks by a mantle-derived melt. Mesozoic flysch is the likely source of the crustal component of the hybrid magmas. Geologic evidence suggests that the Talkeetna superterrane collided with stable Alaska after Early Cretaceous time. The flysch basin, lying south of stable Alaska, was closed by northward movement of the Talkeetna superterrane; maximum age for basin closure and terrane accretion is middle Cretaceous (Cenomanian). Paleomagnetic evidence indicates that all terranes north of the DFS have been part of stable Alaska since the Paleocene and that northward movement of Wrangellia was completed by 50 Ma. Granitic rocks of the McKinley sequence may be products of terrane accretion; the granitic rocks crystallized from hybrid magmas produced during terrane collision and deformation of the flysch basin. Isotopic ages of the McKinley sequence establish the time of final accretion of the Talkeetna superterrane as Paleocene.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB090iB13p11413","issn":"01480227","usgsCitation":"Lanphere, M.A., and Reed, B., 1985, The McKinley Sequence of granitic rocks: A key element in the accretionary history of southern Alaska: Journal of Geophysical Research Solid Earth, v. 90, no.

In 1981 USGS initiated production of orthophotoquads of Alaska, also at a scale of 1:63,360 to be compatible with the topographic map series. An orthophotoquad (OQ) is prepared from a rectified or differentially rectified and scaled black-and-white photographic image published in quadrangle format. The current status of the Alaska OQ program is summarized and sample OQ's are illustrated. Engineering applications of orthophotoquads are discussed, with an emphasis on their use in the on-shore and near-shore areas.

New paleontologic data from fossil localities shown in figure 49 suggest that some strata assigned to the Orca Group are of middle Eocene age and possibly as young as late Eocene or Oligocene.

The basin and channels were filled with glacial and glacialmarine sediment before and during the time that ice retreated and oceanic conditions returned. Restricted marine conditions prevailed in early Holocene time and sediment prograded transversely into the strait from the adjacent landmasses, with some localized dispersal to the deep, central strait.

Enhanced preservation correlates with early diagenetic concretion formation at or near the sediment-water interface and with higher carbonate, organic material, and metallic cation content than in surrounding rocks. Early diagenetic growth is inferred by diverging sedimentary laminations and small-scale sedimentary structures in fossiliferous carbonate concretions. High initial concentrations of microorganisms or fecal pellets may commonly be responsible for incipient carbonate-concretion growth. Excellent preservation is demonstrated by radiolarians and palynomorphs extracted from a carbonate concretion from the Middle Jurassic Shelikof Formation, southern Alaska.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1985)13<212:CCAISH>2.0.CO;2","issn":"00917613","usgsCitation":"Blome, C., and Albert, N., 1985, Carbonate concretions: an ideal sedimentary host for microfossils: Geology, v. 13, no. 3, p. 212-215, https://doi.org/10.1130/0091-7613(1985)13<212:CCAISH>2.0.CO;2.","productDescription":"4 p.","startPage":"212","endPage":"215","numberOfPages":"4","costCenters":[],"links":[{"id":220619,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f36de4b0c8380cd4b7e1","contributors":{"authors":[{"text":"Blome, C.D.","contributorId":60647,"corporation":false,"usgs":true,"family":"Blome","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":365076,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Albert, N.

To evaluate the likelihood of such an occurrence, the tephra deposits of the region have been inventoried. Approximately 90 deposits of Holocene age are sufficiently thick to have been preserved for sampling; the frequency of such major tephrafalls ranges from 1 every 200 years near sources on the west side of upper Cook Inlet, to 1 every 1000 years on the more populated east side. The volcanoes located on the west side of upper Cook Inlet are, from north to south, Hayes, Spurr, Redoubt, and Iliamna. Hayes volcano produced the most extensive set of 6 to perhaps 8 tephra layers in the region about 3650 yr B.P. and produced one other, less extensive tephra layer during Holocene time. Spurr and Redoubt volcanoes have produced, respectively, approximately 35 and 30 Holocene layers which were dispersed eastward toward population centers. No Holocene tephra layers of Iliamna have been recognized with certainty; consequently, several tephra layers which originated to the south of the region must have a source at Augustine Volcano, or some more distant volcano. Tephra layers of Hayes volcano are calc-alkaline dacites. Most of the Spurr deposits are tholeiitic, basaltic andesites whereas those of Redoubt Volcano are calc-alkaline andesites and dacites. ?? 1985.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Riehle, J., 1985, A reconnaissance of the major Holocene tephra deposits in the upper Cook Inlet region, Alaska: Journal of Volcanology and Geothermal Research, v. 26, no. 1-2, p. 37-74.","startPage":"37","endPage":"74","numberOfPages":"38","costCenters":[],"links":[{"id":222283,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e538e4b0c8380cd46bf3","contributors":{"authors":[{"text":"Riehle, J.R.","contributorId":73573,"corporation":false,"usgs":true,"family":"Riehle","given":"J.R.","affiliations":[],"preferred":false,"id":364817,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
