These rocks were invaded, probably in the Tertiary, by dikes and a small stock of porphyry. The ore deposits of the area are the Golden Zone breccia pipe, a nearly vertical body about in the center of the porphyry stock, and steeply dipping veins. Most veins strike north to northeast and are commonly only 1-5 feet thick, but locally are as much as 15 feet thick. Both pipe and vein deposits are gold deposits of low to moderate grade that are characterized by abundant arsenopyrite; some contain possibly economic amounts of copper, lead and zinc minerals. Of the deposits of the mine area, only the Golden Zone has been explored to any extent, and both it and some of. the veins deserve further exploration to determine their potential.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr68122","usgsCitation":"Hawley, C.C., Clark, A.L., and Benfer, J.A., 1968, Geology of the Golden Zone mine area, Alaska: U.S. Geological Survey Open-File Report 68-122, Report: 18 p.; 1 Plate: 25.60 × 20.18 inches, https://doi.org/10.3133/ofr68122.","productDescription":"Report: 18 p.; 1 Plate: 25.60 × 20.18 inches","costCenters":[],"links":[{"id":496185,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_8250.htm","linkFileType":{"id":5,"text":"html"}},{"id":42692,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1968/0122/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42691,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0122/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":147063,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1968/0122/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Golden Zone mine area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.667,\n              63.225\n            ],\n            [\n              -149.667,\n              63.202\n            ],\n            [\n              -149.628,\n              63.202\n            ],\n            [\n              -149.628,\n              63.225\n            ],\n            [\n              -149.667,\n              63.225\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db6801bd","contributors":{"authors":[{"text":"Hawley, C.

Though some intracontinental provincialism is evident, particularly among Lower and Middle Triassic ammonoid faunas, various local sections where parts of the faunal sequence are preserved—sections in southeastern Idaho, western Nevada, northern California, northeastern Oregon, northeastern British Columbia, southwestern British Columbia, southeastern and southern Alaska, and the Arctic Islands of Canada—can be pieced together in overlapping fashion into a unified sequential framework of biostratigraphic units presented in an annotated zonal chart. At least 35 zonal units of demonstrably different age are now recognized; these units are apportioned among the Griesbachian, Dienerian, Smithian, and Spathian Stages of the Lower Triassic; the Anisian and Ladinian Stages of the Middle Triassic; and the Karnian, Norian and Rhaetian Stages of the Upper Triassic. This zonation based on North American ammonoid faunas for the first time provides an objective and reasonably detailed standard of reference for expressing the age and correlation of the marine Triassic rocks of Canada and the United States.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/SPE110-p1","usgsCitation":"Silberling, N., and Tozer, E.T.,

Volcanism on Nunivak Island occurred in distinct episodes separated by quiet intervals that lasted from 1.6 to 0.6 m.y. During the past 6 m.y., tholeiitic basalt was erupted during at least five such episodes, and highly undersaturated alkalic basalt was erupted during at least three episodes. The oldest volcanic rock found on Nunivak Island is an alkalic basalt, succeeded by repeated alternations of tholeiitic and alkalic basalt. During the last episode of tholeiitic volcanism, 130 cu km of basalt erupted during a well-defined interval that lasted from 0.9 to 0.3 m.y. ago. A nearly contemporaneous eruption of alkalic basalt has continued vigorously to historic times and has covered the central part of the island with small cones, flows, and tephra from explosion craters. The volume of alkalic basalt of the latest episode of volcanic activity is from 0.7 to 2.0 percent of the volume of the associated tholeiite. At least one earlier eruption of alkalic basalt occurred in close association with the eruption of tholeiite. As on Hawaii, the highly undersaturated alkalic basalts on Nunivak contain abundant ultramafic inclusions.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Studies in Volcanology","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/MEM116-p377","usgsCitation":"Hoare, J., Condon, W., Cox, A., and Dalrymple, G.B., 1968, Geology, paleomagnetism, and potassium-argon ages of basalts from Nunivak Island, Alaska, chap. <i>of</i> Studies in Volcanology, v. 116, p. 377-413, https://doi.org/10.1130/MEM116-p377.","productDescription":"38 p.","startPage":"377","endPage":"413","costCenters":[],"links":[{"id":373150,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Nunivak Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -167.49755859375,\n              60.22071908232925\n            ],\n            [\n              -167.3382568359375,\n              59.98250201795759\n            ],\n            [\n              -166.343994140625,\n              59.77022610242765\n            ],\n            [\n              -166.08581542968747,\n              59.72040749601443\n            ],\n            [\n              -165.9869384765625,\n              59.825493056630116\n            ],\n            [\n              -165.4595947265625,\n              59.86964070806754\n            ],\n            [\n              -165.6298828125,\n              60.05935761134086\n            ],\n            [\n              -165.6134033203125,\n              60.2888540595603\n            ],\n            [\n              -165.849609375,\n              60.378575303227215\n            ],\n            [\n              -165.95947265624997,\n              60.36228069247893\n            ],\n            [\n              -166.1572265625,\n              60.46263441109029\n            ],\n            [\n              -166.3824462890625,\n              60.39757538658664\n            ],\n            [\n              -166.5802001953125,\n              60.40571488624096\n            ],\n            [\n              -166.9317626953125,\n              60.297020731204576\n            ],\n            [\n              -166.8603515625,\n              60.23981116999893\n            ],\n            [\n              -167.3492431640625,\n              60.275238405838536\n            ],\n            [\n              -167.49755859375,\n              60.22071908232925\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"116","noUsgsAuthors":false,"publicationDate":"1968-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Hoare, J.

It is based on field examination June 8-12, 1966, in company with Messrs. E. B. Eckel and E. G. Dobrovolny, field work September 19-October 3, 1966, and May 1-June 4, 1967, on discussions with the staff of The Alaska Railroad, my colleagues, and Professor H. B. Seed of the University of California, and on review of published and unpublished material pertinent to the area and its problems.</p><p>During the fall of 1966 a detailed topographic map of the port area was prepared for The Alaska Railroad by Jay Whiteford and Associates. During late 1966 and early 1967 a drilling, sampling and soils testing program in an area of immediate interest along Boring Lines 1 and 2 was made by Adams, Corthell, Lee, Wince, and Associates (ACLW), a consultant engineering firm, under contract to The Alaska Railroad. Most of the basic data used in this report for stability analyses, such as the geometry of the ground surface and the physical properties of the materials, was derived from the Whiteford map and the ACLW investigations.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr68310","usgsCitation":"Varnes, D., 1968, Alaska Railroad Terminal Reserve, Anchorage,
