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.

It also attempts to express this knowledge in terms that the planner can use to test alternatives during the planning process. Because the available data used in this report are applied to a portion of the Brandywine Creek basin in Pennsylvania, this can be considered as a report on the basic hydrologic conditions of the Brandywine Creek basin prior to the beginning of major urbanization. Because the available data are not yet adequate, this report can be considered as a compilation of tentative suggestions in the form of an explanatory, not a definitive handbook.</p>\n<p>The application of current knowledge of the hydrologic effects of urbanization to the Brandywine should be viewed as a forecast of conditions which may be expected as urbanization proceeds. By making such forecasts in advance of actual urban development, the methods can be tested, data can be extended, and procedures improved as verification becomes possible.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/cir554","usgsCitation":"Leopold, L.B., 1968, Hydrology for urban land planning
