The Orca Group also probably underlies a large part of the Gulf of Alaska Tertiary province and the continental shelf south of the outcrop belt; coextensive rocks to the southwest on Kodiak Island are called the Ghost Rocks and Sitkalidak Formations. \r\n\r\nThe Orca Group was pervasively faulted, tightly folded, and metamorphosed regionally to laumontite and prehnite-pumpellyite facies prior to, and perhaps concurrently with, intrusion of early Eocene granodiorite and quartz monzonite plutons. \r\n\r\nIn eastern Prince William Sound, 95% of the Orca sedimentary rocks are interbedded feldspathic and lithofeldspathic sandstone, siltstone, and mudstone turbidites. Lithic components vary widely in abundance and composition, but labile sedimentary and volcanic grains dominate. A widespread yet minor amount of the mudstone is hemipelagic or pelagic, with scattered foraminifers. Pebbly mudstone with rounded clasts of exotic lithologies and locally conglomerate with angular blocks of deformed sandstone identical to the enclosing matrix are interbedded with the turbidites. \r\n\r\nThick and thin tabular bodies of altered tholeiitic basalt are locally and regionally conformable with the sedimentary rocks, and constitute 15-20% of Orca outcrops in eastern Prince William Sound. The basalt consists chiefly of pillowed and nonpillowed flows, but also includes minor pillow breccia, tuff, and intrusive rocks. Nonvolcanic turbidites are interbedded with the basalt; lenticular bioclastic limestone, red and green mudstone, chert, and conglomerate locally overlie the basalt, but are supplanted upward by turbidites. From west to east, basalts within the Orca Group become increasingly fragmental and amygdaloidal. Such textural changes probably indicate shallower water to the east. \r\n\r\nA radial distribution of paleocurrents and distinctive associations of turbidite facies within the sedimentary rocks suggest that the Orca Group in eastern Prince William Sound was deposited on a westward-sloping, complex deep-sea fan. Detritus was derived primarily from 'tectonized' sedimentary, volcanic, and plutonic rocks. Coeval submarine volcanism resulted in intercalation of basalt within prisms of terrigenous sediment.","language":"ENGLISH","doi":"10.3133/ofr7683","usgsCitation":"Winkler, G., 1976, Deep-sea fan deposition of the lower Tertiary Orca Group, eastern Prince William Sound, Alaska: U.S. Geological Survey Open-File Report 76-83, iii, 20 leaves : ill. ; 28 cm., https://doi.org/10.3133/ofr7683.","productDescription":"iii, 20 leaves : ill. ; 28 cm.","costCenters":[],"links":[{"id":170947,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0083/report-thumb.jpg"},{"id":84952,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0083/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672527","contributors":{"authors":[{"text":"Winkler, Gary R.","contributorId":75513,"corporation":false,"usgs":true,"family":"Winkler","given":"Gary R.","affiliations":[],"preferred":false,"id":237089,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A comprehensive review of the Lisburne in the subsurface of the eastern Arctic Slope indicates attractive reservoir characteristics in a favorable source and migration setting where numerous trapping mechanisms appear to be available. Evaluation of this group as a potential exploration objective is particularly timely in view of impending offshore sales in the Beaufort Sea and current exploration programs underway in the Prudhoe Bay area and the Naval Petroleum Reserve.</p><p>Dolomite and sandstone have been identified as reservoir rocks. Oolitic grainstone is a common rock type, but all observations to date indicate little reservoir potential owing to complete void filling by calcite cement. The most important reservoir rock as judged by thickness, areal extent, and predictability is microsucrosic (10-30 μ) dolomite of intertidal to supratidal origin. It is present throughout the Lisburne and is most abundant near the middle of the sequence. Northward it decreases in thickness from 1,000 feet (300 m) to less than 100 feet (30 m). Porosity of the dolomite as determined in selected wells averages between 10 and 15 percent and attains a maximum of slightly more than 25 percent. Net thickness of reservoir rocks (i.e., rocks with greater than 5 percent porosity) varies in these wells from 140 feet (40 m) to 390 feet (120 m). Oil shows are common, and drill-stem tests have yielded as much as 1,600 bbls/day oil and 22 MMcf/day gas in the Lisburne pool of the Prudhoe Bay Field and as much as 2,057 bbls/day saltwater outside the field area. The occurrence of dolomite over such a large area makes its presence in the offshore Beaufort Sea and adjacent Naval Petroleum Reserve No. 4 fairly certain. The occurrence of sandstone as thick as 140 feet (40 m) in the middle and upper part of the Lisburne in two coastal wells suggests that larger areas of sandstone may be found to the north in offshore areas. Shows of oil and gas and a saltwater flow of 1,470 bbls/day have been recorded from this sandstone facies.</p><p>Shales of Permian and Cretaceous age unconformably overlie the Lisburne, providing adequate sealing beds above potential reservoirs. Impermeable limestone (completely cemented grainstone) and thin beds of shale may serve as seals within the Lisburne, but the possibility of fractures in these units may negate their sealing capability.</p><p>The most favorable source rock for Lisburne hydrocarbons appears to be Cretaceous shale that unconformably overlies the Lisburne east of Prudhoe Bay. This shale is reported by Morgridge and Smith (1972) to be a rich source rock and is the most likely source for the entire Prudhoe Bay Field. A source within the Lisburne or within the underlying Kayak Shale is postulated to explain oil shows in the southernmost Lisburne wells. This postulated source may be in a more basinal facies of the Lisburne and may be similar to dark shale in the upper Lisburne found in thrust slides in the Brooks-Range. Coal in the underlying Endicott Group is a possible source for dry gas. It is inferred that at the present time much of this coal is in a gas—generating regime downdip from the Prudhoe Bay Field area.</p><p>Stratigraphic traps involving the Lisburne Group may exist as a result of widespread Permian and Cretaceous unconformities. Structural traps related to normal faulting may occur along the trend of the Barrow Arch, and faulted anticlines are numerous in the foothills of the Brooks Range. Combination traps are possible along the trend of the Barrow Arch at places where both stratigraphic and structural trap might exist.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76786","usgsCitation":"Bird, K.J., and Jordan, C.F., 1976, The Lisburne Group: A potential major hydrocarbon objective of the Arctic Slope, Alaska: U.S. Geological Survey Open-File Report 76-786, 45 p., https://doi.org/10.3133/ofr76786.","productDescription":"45 p.","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":140044,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0786/report-thumb.jpg"},{"id":427884,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0786/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","otherGeospatial":"Arctic Slope","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -167.79230672684753,\n              70.95128032471553\n            ],\n            [\n              -167.79230672684753,\n              68.64028489549236\n            ],\n            [\n              -143.12168301430032,\n              68.64028489549236\n            ],\n            [\n              -143.12168301430032,\n              70.95128032471553\n            ],\n            [\n              -167.79230672684753,\n              70.95128032471553\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67bc1b","contributors":{"authors":[{"text":"Bird, Kenneth J. kbird@usgs.gov","contributorId":1015,"corporation":false,"usgs":true,"family":"Bird","given":"Kenneth","email":"kbird@usgs.gov","middleInitial":"J.","affiliations":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"preferred":true,"id":156799,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jordan, Clifton F.","contributorId":95203,"corporation":false,"usgs":true,"family":"Jordan","given":"Clifton","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":156800,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Three methods were used at each of five stations to increase sampling effectiveness and to evaluate each method. Chironomidae and Plecoptera comprised 91 percent of all individuals and 47 percent of all taxa in the combined faunal list. At each station, the most abundant organisms were taken by all methods but the less abundant ones by only one or two methods. The dip net collected the highest percentage of taxa, and the second highest percentage of individuals. The 10-rock method collected the highest percentage of individuals but was relatively ineffective for taxa. The drift net collected the fewest individuals, but the percentage of taxa was relatively high. Of the 27 unique taxa (those taxa collected by only one of the methods), 15 were collected by dip net, 8 by drift net, and 4 by the 10-rock method. The methods differed in their effectiveness with regard to collecting the most abundant taxonomic groups. Although the dip net was most effective for collecting taxa, more thorough scrubbing of substrates to remove clinging organisms probably would improve the technique.</p>","language":"English","publisher":"U.
