Five formations have been recognized as a result of of recent investigations by the author and other geologists of the Navy Oil Unit, U.S. Geological Survey. In the western Brooks Range, the three formations present below the Lisburns formation are: Utukok formation (Upper Touranisian to Lower Visean), Montak formation (restricted) (Upper Devonian to Lower Tournaisian (?)) and Hunt Fork (?) formation (Upper Devonian). In the central Brooks Range the Kayak formation (Lower to Upper Tournaisian), Kanayut formation (Upper Devonian to Lower Tournaisian (?)), and Hunt Fork formation (Upper Devonian) lie below the Lisburns formation.</p><p>Lithologic and faunal characteristics of these sedimentary units reveal the regional pattern of sedimentation and suggest specific paleoecologic environments. The chart conglomerates in the Kanayut and Noatuk formations are thought to have formed in a belt characterized by fluctuating marine and nonmarine conditions, the chart source being a mid-Devonian ragolith.</p><p>Analysis of formulas suggest certain correlations with the European, Siberian, and western Cordilleran sections.</p><p>Described faunas of the Utukok and Kayak formations include 40 braciopod species and varieties, 9 echinodera species, 2 bryzoan species, 8 molluscan species, and 1 tribute species, of which 13 are new.</p>","language":"English","publisher":"U.S. Geological

These areas are probably only local manifestations of mineralization that affected a much broader area and formed antimony-bearing deposits in neighboring districts, the closest of which is 50 miles away. The ores were exposed largely as a result of lode gold mining, but at two periods in the past, high prices for antimony ore warranted an independent production and about 2500 tons of stibnite ore was shipped.\r\n\r\nThe sulfide deposits occupy the same fractures along which a gold-quartz mineralization of greater economic importance occurred; and both are probably genetically related to igneous rocks which intrude the schistose country rock. The sulfide is in part contemporaneous with some late-stage quartz in which it occurs as disseminated crystals; and in part the latest filling in the mineralized zones where it forms kidney-shaped masses of essentially solid sulfide. One extremely long mass must have contained nearly 100 tons of ore, but the average of the larger kidneys is closer to several tons. Much of the ore is stibnite, with quartz as a minor impurity, and assays show the tenor to vary from 40 to 65 percent antimony. Sulphantimonites are less abundant but likewise occur as disseminated crystals and as kidney-shaped bodies. Antimony oxides appear on the weathered surface and along fractures within the sulfide ore.\r\n\r\nDeposits containing either stibnite or sulphantimonite are known at more than 50 localities, but only eighteen have produced ore and the bulk of this came from the mines. The geology of the deposit, and the nature, extent, and period of the workings are covered in the detailed descriptions of individual occurrences.\r\n\r\nSeveral geologic and economic factors, which greatly affect prospecting and mining for stibnite ore in the area, are outlined. The principal available ore and reserves are considered to be ores earlier mined but never shipped, ore minable from near-surface deposits, and ores recoverable as a by-product of future gold mining. The outlook for stibnite production in the district is very uncertain. Apparently the greater portion of stibnite ore has already been recovered and present operations will strip the two principal areas of the district. This conclusion is based on the scanty discoveries since the last war and the fact that the areas are so pock-marked with prospects that there is little likelihood that any other large near-surface bodies remain to be discovered. Future prospecting would essentially be limited to attempts to seek the continuation of lodes previously having high yields of stibnite.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr5146","usgsCitation":"Killeen, P.L., and Mertie, J.B., 1951, Antimony ore in the Fairbanks district, Alaska: U.S. Geological Survey Open-File Report 51-46, 43 p.; 3 maps (2 folded) ;27 cm., https://doi.org/10.3133/ofr5146.","productDescription":"43 p.; 3 maps (2 folded) ;27 cm.","costCenters":[],"links":[{"id":149030,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1951/0046/report-thumb.jpg"},{"id":43139,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1951/0046/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":43140,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1951/0046/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":43141,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1951/0046/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67aea4","contributors":{"authors":[{"text":"Killeen, Pemberton Lewis","contributorId":108090,"corporation":false,"usgs":true,"family":"Killeen","given":"Pemberton","email":"","middleInitial":"Lewis","affiliations":[],"preferred":false,"id":169493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mertie, John B.

It emerges from the mountains 10 miles east of Anchorage and above that point has a drainage area of 90 square miles. Stream flow records for the 4 year period, 1947 through 1950, show a mean flow of 156 second-feet with a variation from 114 second-feet for 1950 to 198 second-feet for 1949. The monthly distribution of flow has considerable variation with about one-fifth of the runoff in the 6 month period December to May, and about one-half the runoff in the 3 month period, June, July, and August. Storage is therefore required for regulation and most effective use of the streamflow. There is no natural storage in the basin. Storage possibilities and power developments are not favorable. Two possible sites are considered in this report, one at mile 1.0 and one at mile 3.5. Development at the former site would produce 3200 and 2300 KW for 50 percent and 90 percent of the time while development at the latter would produce 5000 and 4400 KW for 50 percent and 90 percent of the time.</p><p>Ship Creek is not a glacier fed stream and thus is free from glacial silt and offers a good source of municipal and industrial water supply. The natural flow is sufficient to supply present demands and it is believed that with the development of storage demands created by any foreseeable expansion of Anchorage and the surrounding area can readily be met.</p>","language":"English","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr5140","usgsCitation":"Colbert, J., 1951, Water utilization Ship Creek near Anchorage, Alaska: U.S. Geological Survey Open-File Report 51-40, Report: iii, 21 p.; Appendixes: 1-3 p., https://doi.org/10.3133/ofr5140.","productDescription":"Report: iii, 21 p.; Appendixes: 1-3 p.","costCenters":[],"links":[{"id":428750,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1951/0040/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":155654,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1951/0040/report-thumb.jpg"}],"country":"United States","state":"Alaska","city":"Anchorage","otherGeospatial":"Ship Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -150.25062856052656,\n              61.26580240344245\n            ],\n            [\n              -150.25062856052656,\n              61.082783211646415\n            ],\n            [\n              -149.73850269828569,\n              61.082783211646415\n            ],\n            [\n              -149.73850269828569,\n              61.26580240344245\n            ],\n            [\n              -150.25062856052656,\n              61.26580240344245\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f3e4b07f02db5efaed","contributors":{"authors":[{"text":"Colbert, Jesse L.","contributorId":107730,"corporation":false,"usgs":true,"family":"Colbert","given":"Jesse L.","affiliations":[],"preferred":false,"id":188801,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Barnes' report covers investigations of coal-bearing rocks of the Kenai formation of Tertiary age in a coastal belt between Bluff Point, 1-1/2 miles west of Homer, and the head of Kachemak Bay. Cobb's report deals with similar rocks exposed along the shore between Bluff Point and Deep Creek. The present report covers an extension of this work from Deep Creek along the east shore of Cook Inlet to the most northerly exposures of rocks of the Kenai formation in the beach bluffs about 6 miles south of the mouth of the Kasilof River, Outcrops of coal-bearing rocks along the Storling Highway and the lower reaches of the Ninilchik River also were investigated. The writer, assisted by F.J. Markewicz, carried on the field work which is the basis for this report between June 1 and August 12, 1950. Field work comprised measurement of stratigraphic sections, tracing of coal beds, geologic mapping along the shorn of Cook Inlet, the lower part of the Ninilchik River, and the Sterling Highway, and sampling of coal beds.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr5157","usgsCitation":"Cobb, E.H., 1951, Coal investigations on the northwest margin of the Homer district, Kenai coal field, Alaska in 1950: U.S. Geological Survey Open-File Report 51-57, Report: 13 p.; 3 Plates: 50.15 x 41.84 inches or smaller, https://doi.org/10.3133/ofr5157.","productDescription":"Report: 13 p.; 3 Plates: 50.15 x 41.84 inches or smaller","costCenters":[],"links":[{"id":146470,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1951/0057/report-thumb.jpg"},{"id":419793,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1951/0057/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":419794,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1951/0057/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":419795,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1951/0057/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":419796,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1951/0057/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","otherGeospatial":"Kenai coal field","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -151.97606895484873,\n              59.86995468899815\n            ],\n            [\n              -151.97606895484873,\n              59.29432591306937\n            ],\n            [\n              -151.0279167616619,\n              59.29432591306937\n            ],\n            [\n              -151.0279167616619,\n              59.86995468899815\n            ],\n            [\n              -151.97606895484873,\n              59.86995468899815\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49ade4b07f02db5c6f5e","contributors":{"authors":[{"text":"Cobb, Edward Huntington","contributorId":25916,"corporation":false,"usgs":true,"family":"Cobb","given":"Edward","email":"","middleInitial":"Huntington","affiliations":[],"preferred":false,"id":167181,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
