St. George basin is a long (300 km), narrow (30-50 km) graben whose long axis strikes northwestward, parallel to the continental margin of the southern Bering Sea. Located near the Pribilof Islands, and beneath the virtually featureless Bering Sea shelf, the basin is filled with more than 10 km of sedimentary deposits. These sedimentary rocks are ruptured by normal faults associated with the sides of the graben; these ruptures commonly correlate with offsets in the basement surface. Offset along these faults increases with depth implying that they are growth-type structures. Basement rocks, that floor and flank St. George basin are part of an assemblage of Mesozoic eugeosynclinal rocks that extends from southern Alaska to eastern Siberia beneath the Bering Sea margin and outer shelf. A parallel belt of igneous rocks of late Mesozoic and earliest Tertiary age may also extend from western Alaska to northeastern Siberia beneath the inner Bering Sea shelf.
The Bering Sea margin and adjacent shelf were apparently uplifted by the end of Mesozoic time, resulting in deep subaerial erosion• Following uplift, the outer Bering Sea shelf has undergone extensional rifting and regional subsidence. Differential subsidence has resulted in the formation of a series of basement ridges and basins whose axes parallel the Bering Sea margin. Some of these basins are very large to gigantic in size, e.g., St. George basin, and involve crustal subsidence exceeding 10 km. Such large scale crustal collapse suggests deep crustal or upper mantle processes, such as thermal metamorphism or stress-induced crustal migration.
Nine wells drilled along the northern coast of the Alaska Peninsula, as well as several onshore Soviet wells in northeastern Siberia, relate directly to the submerged basins of the Bering Sea shelf. Although all of the wells on the Alaska Peninsula were abandoned as dry holes, shows of oil and gas were found. In addition, Soviet drilling resulted in the discovery of oil and gas
shows in Oligocene and Miocene sandstone.
Regional geologic and geophysical mapping suggests that there are suitable source beds, reservoir rocks, and traps within St. George basin. However, it is not known if hydrocarbons are present or if the possible reservoirs are of commercial size. A resource appraisal of St. George basin out to 200 meters water depth indicates that, at 5 percent probability, 6.4 billion barrels of oil and 18.6 trillion cubic feet of gas may be in the basin; at 95 percent probability 0.8 billion barrels of oil and 4.5 trillion cubic feet of gas may be in the basin. The statistical mean of the appraisal is 2.7 billion barrels of oil and 10.3 trillion cubic feet of gas.
A large number of faults, evidence for recent movement along some of the faults, and high seismicity all indicate that faulting is a major environmental concern for the outer continental shelf region of the southern Bering Sea, especially in St. George basin. Most of the faults are potentially active and their movement is probably influenced by the local geology, including basement structures and sediment loading. Unstable sediment masses pose potential threats to resource development in the vicinity of the Pribilof Canyon. Volcanic activity along the Aleutian arc south of St. George basin may also pose an environmental hazard to petroleum development in the area. Another environmental hazard is the presence of shallow gas pockets, which could pose such problems during drilling as blowouts and liquefaction of bottom sediment.

A digital model calibrated to conditions in Sand Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, summer and winter low flows. The Greensburg wastewater-treatment facility is the only point-source waste Load affecting Sand Creek in the vicinity of Greensburg. Nonpoint, unrecorded waste loads seemed to be significant during three water-quality surveys done by the Indiana State Board of Health.
Natural streamflow in Sand Creek during the summer and annual 7-day, 10-year low flow is zero, so no benefit from dilution is provided. Current (1978) ammonia-nitrogen and dissolved-oxygen concentrations of effluent from the Greensburg wastewater-treatment facility will not meet Indiana stream water-quality standards for ammonia toxicity and dissolved oxygen.
Model simulations indicate that benthic-oxygen demand, nitrification, and the dissolved-oxygen concentration of the wastewater effluent are the most significant factors affecting the in-stream dissolved-oxygen concentrations during summer low flows. The model predicts that with a benthic-oxygen demand of 1.5 grams per square meter per day at 20° Celsius the stream has no additional waste-load assimilative capacity.
The model also indicates that if the deoxygenation rate for nitrogenous biochemical-oxygen demand ranges from 0.2 to 1.0 day-1 at 20° Celsius and the in-stream ammonia-nitrogen toxicity standard is not exceeded, the minimum dissolved-oxygen concentration of the stream is primarily controlled by the dissolved-oxygen concentration of the wastewater effluent and the benthic-oxygen demand. If the deoxygenation rate for nitrogenous biochemical-oxygen demand is 3.5 day-1 or greater at 20° Celsius, then even with an effluent total ammonia-nitrogen concentration of 2.5 milligrams per liter the minimum 24-hour average in-stream dissolved-oxygen concentration of at least 5 milligrams per liter cannot be met during summer low flows.
Current carbonaceous biochemical-oxygen demand loads from the Greensburg wastewater-treatment facility are sufficient to maintain an average dissolved-oxygen concentration of 5 milligrams per liter, the State's water-quality standard for streams during winter low flows.

Person, personal communication, 1979) occurred beneath the Chugach and St. Elias mountains of southern Alaska (fig. 1). This is a region of complex tectonics resulting from northwestward convergence between the Pacific and North American plates. To the east, the northwest-trending Fairweather fault accommodates the movement with dextral slip of about 5.5 cm/yr (Plafker, Hudson, and others, 1978); to the west, the Pacific plate underthrusts Alaska at the Aleutian trench, which trends southwestward (Plafker 1969). The USGS has operated a telemetered seismic network in southern Alaska since 1971 and it was greatly expanded along the eastern Gulf of Alaska in September 1974. The current configuration of stations is shown in Figure 9. Technical details of the network are available in published earthquake catalogs (Lahr, Page, and others, 1974; Fogleman, Stephens, and others, 1978). Preliminary analysis of the data from this network covering the time period September 1, 1978 through March 10, 1979, as well as worldwide data for the main shock will be discussed in this paper.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr79670","usgsCitation":"Lahr, J.C., Plafker, G., Stephens, C., Foglean, K.A., and Blackford, M.E., 1979, Interim report on the St. Elias, Alaska earthquake of 28 February 1979: U.S. Geological Survey Open-File Report 79-670, 23 p., https://doi.org/10.3133/ofr79670.","productDescription":"23 p.","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":140230,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_79_670.gif"},{"id":259117,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0670/of79-670.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":259293,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1979/0670/","linkFileType":{"id":5,"text":"html"}},{"id":407802,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_75015.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"St. Elias Mountains, Chugach Mountains","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -142,\n 59.75\n ],\n [\n -139.5,\n 59.75\n ],\n [\n -139.5,\n 61\n ],\n [\n -142,\n 61\n ],\n [\n -142,\n 59.75\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dbe4b07f02db5e0a4d","contributors":{"authors":[{"text":"Lahr, John C.","contributorId":20328,"corporation":false,"usgs":true,"family":"Lahr","given":"John","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":154931,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":154929,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stephens, C.D.","contributorId":18752,"corporation":false,"usgs":true,"family":"Stephens","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":154930,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Foglean, K.

Approximately 1,000 of the lakes are listed by 7.5-minute quadrangle topographic-map name, lake-identification number, latitude and longitude, and county. Other data given are shape of lake, maximum length, mean width, length and development of shoreline, surface area, orientation, presence of a stream inlet or outlet, and geologic data (geologic formation of area surrounding the lake and the mined coal-bed member). Field data (sampling date, pH, specific conductance, apparent color of lake, and general vegetation along the shoreline) were collected for 287 of the lakes.\r\n\r\nTwo hundred eighty-seven lakes were sampled once for pH and specific conductance. Vegetation along the shoreline and apparent color of each lake were identified at the same time. Although these data are not sufficient to quantify the water quality of the lakes, they do illustrate the variability of these characteristics. The pH of the 287 lakes ranged from 2.5 to 10.0; however, the pH of 80 percent of them ranged from 6 to 9. Specific conductance ranged from 99 to 3,800 micromhos per centimeter at 25? Celsius. Specific conductance for approximately 70 percent of the lakes in the Staunton and Brazil formations was less than 500 micromhos per centimeter at 25? Celsius, but for approximately 65 percent in the Dugger and Petersburg Formations it was greater than 1,000 micromhos per centimeter at 25? Celsius. The apparent colors of the lakes observed were varying shades of aqua, blue, brown, lime green, red, and green. Eighty percent of the lakes sampled were green.\r\n\r\nLake sizes ranged from a chosen minimum of 0.5 acre to a maximum of 344 acres. Maximum length ranged from 0.1 to 2 miles, and the mean width was generally less than 0.8 mile.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791639","issn":"0094-9140","usgsCitation":"Bobo, L.L., 1979, Gazetteer of coal-mine lakes in southwestern Indiana: U.S. Geological Survey Open-File Report 79-1639, 1 atlas (iv, 107 p.) :maps ;31 x 46 cm.; (111 over-size sheets - PGS), https://doi.org/10.3133/ofr791639.","productDescription":"1 atlas (iv, 107 p.) :maps ;31 x 46 cm.; (111 over-size sheets - PGS)","costCenters":[],"links":[{"id":156524,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1639/report-thumb.jpg"},{"id":52024,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1639/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b1268","contributors":{"authors":[{"text":"Bobo, Linda L.","contributorId":104053,"corporation":false,"usgs":true,"family":"Bobo","given":"Linda","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":188378,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":46484,"text":"ofr79594 - 1979 - Map showing radiometric ages of rocks in southeastern Alaska","interactions":[],"lastModifiedDate":"2025-08-21T16:30:07.871855","indexId":"ofr79594","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"79-594","title":"Map showing radiometric ages of rocks in southeastern Alaska","docAbstract":"No abstract available.

One stratum of Santonian age near the base of the Galembo Member of the La Luna Formation crops out at many places in the Departments of Santander and Norte de Santander and may be of commercial grade. This stratum is more than one meter thick at several places near Lebrija and near Sardinata, farther south it is locally one meter thick or more near the base of the Guadalupe Formation in the Department of Boyaca. Other phosphorite beds are found at higher stratigraphic levels in the Galembo Member and the Guadalupe Formation, and at some places these may be commercial also. A stratigraphically lower phosphorite occurs below the Galembo Member in the Capacho Formation (Cenomanian age) in at least one area near the town of San Andres, Santander. A phosphorite or pebbly phosphate conglomerate derived from erosion of the Galembo Member forms the base of the Umir Shale and the equivalent Colon Shale at many places.\r\n\r\nDeposition of the apatite took place upon the continental shelf in marine water of presumed moderate depth between the Andean geosyncline and near-shore detrital deposits adjacent to the Guayana shield. Preliminary calculations indicate phosphorite reserves of approximately 315 million metric tons in 9 areas, determined from measurements of thickness, length of the outcrop, and by projecting the reserves to a maximum of 1,000 meters down the dip of the strata into the subsurface. Two mines were producing phosphate rock in 1969; one near Turmeque, Boyaca, and the other near Tesalia, Huila.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791525","issn":"0094-9140","usgsCitation":"Maughan, E.K., Zambrano O., F., Mojica G., P., Abozaglo M., J., Pachon P., F., and Duran R., R., 1979, Paleontologic and stratigraphic relations of phosphate beds in Upper Cretaceous rocks of the Cordillera Oriental, Colombia: U.S. Geological Survey Open-File Report 79-1525, iii, 101 p., 7 over-size sheets :ill., maps ;27 cm., https://doi.org/10.3133/ofr791525.","productDescription":"iii, 101 p., 7 over-size sheets :ill., maps ;27 cm.","costCenters":[],"links":[{"id":153730,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1525/report-thumb.jpg"},{"id":51469,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51470,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51471,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51472,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51473,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51474,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1525/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51475,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1525/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db688f31","contributors":{"authors":[{"text":"Maughan, Edwin K.","contributorId":85172,"corporation":false,"usgs":true,"family":"Maughan","given":"Edwin","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":186635,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zambrano O., Francisco","contributorId":54606,"corporation":false,"usgs":true,"family":"Zambrano O.","given":"Francisco","email":"","affiliations":[],"preferred":false,"id":186632,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mojica G., Pedro","contributorId":67102,"corporation":false,"usgs":true,"family":"Mojica G.","given":"Pedro","email":"","affiliations":[],"preferred":false,"id":186633,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abozaglo M., Jacob","contributorId":74776,"corporation":false,"usgs":true,"family":"Abozaglo M.","given":"Jacob","email":"","affiliations":[],"preferred":false,"id":186634,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pachon P., Fernando","contributorId":15226,"corporation":false,"usgs":true,"family":"Pachon P.","given":"Fernando","email":"","affiliations":[],"preferred":false,"id":186631,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Duran R., Raul","contributorId":106521,"corporation":false,"usgs":true,"family":"Duran R.","given":"Raul","email":"","affiliations":[],"preferred":false,"id":186636,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":38155,"text":"ofr791092 - 1979 - Reconnaissance geology of the Ginny Creek zinc-lead-silver and Nimiuktuk barite deposits, northwestern Brooks Range, Alaska","interactions":[],"lastModifiedDate":"2025-06-25T20:28:40.467948","indexId":"ofr791092","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"79-1092","title":"Reconnaissance geology of the Ginny Creek zinc-lead-silver and Nimiuktuk barite deposits, northwestern Brooks Range, Alaska","docAbstract":"No abstract available.
