The results include the determination of elements by semiquantitative spectrographic analysis, phosphate by X-ray fluorescence, carbon dioxide by acid decomposable carbonate, total carbon by induction furnace, carbonate carbon by conversion using the conversion factor of 0.2727 for amount of carbon in carbon dioxide, and organic carbon by difference. \r\n\r\nA seven- cycle semilogarithmic chart presents the data graphically and illustrates the range, mode, and mean for some of the elements. The chart shows, also, the approximate concentration of the same elements in rocks similar to the black shale and limestone of the Shublik Formation. \r\n\r\nEach sample represents 5 feet of section and is composed of rock chips taken at 1 - foot intervals. The samples are keyed into a stratigraphic column of the formation. \r\n\r\nRocks of the Shublik Formation contain anomalously high concentrations of some of the elements. These same elements might be expected to be high in some of the petroleum from northern Alaska if the Shublik Formation is a source for this petroleum. Several of the stratigraphic intervals may represent, also, a low-grade phosphate deposit.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr70101","usgsCitation":"Detterman, R.L., 1970, Analysis of Shublik Formation rocks from Mt.

Based on present data the gross value of the deposit, with a value of $25.00 or more per ton, is $20,000,000. A belt of metasedimentary rocks, intruded by gabbro to the south and granite to the north, was the host for fissure vein-replacement type mineralization. Most of the mineralization is in a siliceous dolomite transected by fissures.

Original descriptions of the individual fault-events published in English, French, German, or Spanish were used whenever possible, supplemented by translations of selected passages of reports published in Japanese and Chinese. For some events, original descriptions were not published in these languages and secondary sources were used. Although more than 100 fault-events have been reported in the literature, only those for which reliable data (in the judgement of the present writers) were available on at least two of the three parameters M, L, and D are included in this interim report and listed in table 1. Some fault-events have been omitted because the available reports contained significantly different data for the same event and the writers had insufficient basis for choosing between them.</p><p>This report was prepared to permit early release of part of the results of a more comprehensive study of historic surface faulting now under way, and to elicit suggestions and criticisms from users of the report. Comments are especially invited regarding the methods used in designating the fault type and in identifying the main fault.</p><p>The more comprehensive report will deal with subsidiary faults as well as main faults, will have detailed citations of the sources of information, and will discuss various additional aspects of faulting. It is anticipated that reliable data on a few more faults will be obtained, and it is hoped that comments from users of this interim report will permit improvement of the comprehensive report. Thus it is expected that the comprehensive report will contain modifications of the present data and will be of larger scope. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr7034","usgsCitation":"Bonilla, M.G., and Buchanan, J.M., 1970, Interim report on worldwide historic surface faulting (Version 1.1): U.S. Geological Survey Open-File Report 70-34, ii, 32 p., https://doi.org/10.3133/ofr7034.","productDescription":"ii, 32 p.","costCenters":[],"links":[{"id":47569,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0034/report.pdf","text":"Version 1.0","linkFileType":{"id":1,"text":"pdf"}},{"id":150858,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0034/report-thumb.jpg"},{"id":375406,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1970/of1611/","linkFileType":{"id":5,"text":"html"}},{"id":375405,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/of1611/of1611.pdf","text":"Version 1.1","linkFileType":{"id":1,"text":"pdf"}}],"edition":"Version 1.1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dbe4b07f02db5e0921","contributors":{"authors":[{"text":"Bonilla, Manuel G.","contributorId":74384,"corporation":false,"usgs":true,"family":"Bonilla","given":"Manuel","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":178700,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Buchanan, Jane M.","contributorId":32543,"corporation":false,"usgs":true,"family":"Buchanan","given":"Jane","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":178699,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Attention was first focused on this region in the early 1950's, after oil and gas were discovered in the Cretaceous of the North Slope by the U.S. Navy. The presence of similar Cretaceous strata in the Yukon-Koyukuk province and the possibility that some of the broad alluviated lowlands within the province might be underlain by Tertiary basins were pointed out by Gryc and others (1951) and Payne (1955). Between 1954 and 1961 large parts of the province were reconnoitered by oil company surface parties and a small amount of geophysical work was carried out in the Nulato-Kateel and Bethel areas. The explorational activity culminated in 1960-61 with the drilling of two deep tests, a 12,000-foot hole near Nulato on the Yukon River and a 15,000-foot hole at Napatuk Creek in the Yukon-Kuskokwim Coastal Lowland. Apparently neither test revealed oil shows or favorable reservoir rocks, as exploration and leasing activity in the province declined sharply thereafter.</p><p>Since 1954 the U.S. Geological Survey has maintained a modest but continuing program of reconnaissance geologic mapping of the province and its borderlands. Nearly all parts of this vast area have been visited either by helicopter or river boat. Although information in many places is still sketchy, the broad outlines of the surface geology are now known. Subsurface data, however, are almost totally lacking.</p><p>The mapping indicates that the petroleum possibilities over most of the province are limited because of complex structure and scarcity of promising reservoir rocks. Two areas where further exploration seems warranted are the Yukon-Kuskokwim Coastal Lowland and the western part of the Kobuk-Selawik Lowland.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr70257","collaboration":"This report is preliminary and has not been edited or reviewed for conformity with Geological Survey standards","usgsCitation":"Patton, W.W., 1970, Petroleum possibilities of the Yukon-Koyukuk Province, Alaska: U.S. Geological Survey Open-File Report 70-257, Report: 13 p.; 1 Plate: 23.96 x 14.54 inches, https://doi.org/10.3133/ofr70257.","productDescription":"Report: 13 p.; 1 Plate: 23.96 x 14.54 inches","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":422022,"rank":3,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1970/0257/figure-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":422021,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0257/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":148019,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0257/report-thumb.jpg"}],"scale":"5000000","country":"United States","state":"Alaska","otherGeospatial":"Yukon-Koyukuk Province","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -160.73174908925813,\n              66.77942177184187\n            ],\n            [\n              -160.73174908925813,\n              60.34875981757247\n            ],\n            [\n              -156.1810191082801,\n              60.34875981757247\n            ],\n            [\n              -156.1810191082801,\n              66.77942177184187\n            ],\n            [\n              -160.73174908925813,\n              66.77942177184187\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db687e66","contributors":{"authors":[{"text":"Patton, William Wallace Jr.","contributorId":72346,"corporation":false,"usgs":true,"family":"Patton","given":"William","suffix":"Jr.","email":"","middleInitial":"Wallace","affiliations":[],"preferred":false,"id":170991,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Lead, zinc, and silver are the principal ore metals and galena and sphalerito are the ore minerals identified to date. Throughout the core there is a somewhat better correlation of silver with zinc than with lead.</p><p>The richest interval of core is in the main vein, 51-1/2 feet of core from 430 to 482 feet, and averages nearly 20 ounces of silver to the ton. Within this interval, 15 feet of core from 444 to 459 feet averages 60 ounces of silver to the ton. The richest single sample represents the five-foot interval from 454 to 459 feet and is reported to contain nearly 140 ounces of silver to the ton. All of these intervals contain recoverable quantities of lead and zinc and some contain a small amount of gold.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr70324","usgsCitation":"Theobald, P.K., Thompson, C., and Horn, H.D., 1970, Geologic log and chemical data, diamond drill hole 1, Samrah, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 70-324, Report: 61 p.;  4 Figures: 29.84 x 11.90 inches or smaller, https://doi.org/10.3133/ofr70324.","productDescription":"Report: 61 p.;  4 Figures: 29.84 x 11.90 inches or smaller","costCenters":[],"links":[{"id":148894,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0324/report-thumb.jpg"},{"id":498400,"rank":6,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1970/0324/figure-10.pdf","text":"Figure 10","linkFileType":{"id":1,"text":"pdf"}},{"id":498399,"rank":5,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1970/0324/figure-5.pdf","text":"Figure 5","linkFileType":{"id":1,"text":"pdf"}},{"id":498398,"rank":4,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1970/0324/figure-4.pdf","text":"Figure 4","linkFileType":{"id":1,"text":"pdf"}},{"id":498397,"rank":3,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1970/0324/figure-3.pdf","text":"Figure 3","linkFileType":{"id":1,"text":"pdf"}},{"id":498396,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0324/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"Saudi Arabia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -120.1569003387927,\n              42.19240723701009\n            ],\n            [\n              -120.10749572008328,\n              38.838079005221346\n            ],\n            [\n              -114.92237135508793,\n              34.88069804889223\n            ],\n            [\n              -114.98297993586107,\n              31.350750228533002\n            ],\n            [\n              -108.86155573128843,\n              31.164630024551755\n            ],\n            [\n              -108.78553410798668,\n              37.13467902221349\n            ],\n            [\n              -113.85445865369462,\n              37.17625160026044\n            ],\n            [\n              -113.88260270021135,\n              42.186786176024185\n            ],\n            [\n              -120.1569003387927,\n              42.19240723701009\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              42.32738784712694,\n              15.512723400556823\n            ],\n            [\n              55.46938659113218,\n              19.579159163878117\n            ],\n            [\n              56.089387644546775,\n              21.93229208405711\n            ],\n            [\n              48.656849713663576,\n              28.702737353396188\n            ],\n            [\n              39.424873163889,\n              32.90306864705684\n            ],\n            [\n              33.20660131965218,\n              29.600711506057223\n            ],\n            [\n              42.32738784712694,\n              15.512723400556823\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a4f35","contributors":{"authors":[{"text":"Theobald, P.

The study area consists of sixteen 7 1/2-minute quadrangles in Spotsylvania and adjoining counties, Virginia. East-west traverses were flown at a spacing of 1/2 mi and a flight elevation of 500 ft above ground. Geophysical data were compiled at a scale of 1:24,000, with a contour interval of 25 gammas for the magnetics and 25 counts per sec for the aeroradioactivity. The geophysical data were checked in the field, and a lithologic map was made. Correlation is excellent between geophysical data and lithologic units, and it is evident that good detailed aeromagnetic and aeroradioactivity maps can provide appreciable shortcuts in mapping an area such as the Piedmont, where lithologies are complex and outcrops sparse. Radioactivity highs are generally associated with magnetic lows, and more importantly, for purposes of geologic interpretation where the magnetic expression is flat and featureless, there is considerable radioactivity detail for geologic guidance. By using the two geophysical maps in conjunction, the geology between widely spaced outcrops can be worked out. In the study area, high radioactivity and low magnetic intensity characterize granitic rocks, many of which were not previously mapped. Mafic bodies are characterized by high magnetic values and low radioactivity. Much of the area is underlain by a sequence of metamorphosed sedimentary and volcanic rocks having alternating quartz-muscovite and magnetiferous chlorite-actinolite assemblages. © 1970, The Geological Society of America, Inc.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1970)81[3575:COAAAW]2.0.CO;2","issn":"00167606","usgsCitation":"Neuschel, S., 1970,  Correlation of aeromagnetics and aeroradioactivity with lithology in the Spotsylvania area, Virginia: Geological Society of America Bulletin, v. 81, no. 12, p. 3575-3582, https://doi.org/10.1130/0016-7606(1970)81[3575:COAAAW]2.0.CO;2.","productDescription":"8 p.

Because of this, biostratigraphers have commonly based conclusions on the occurrences of relatively few species. The use of binary similarity coefficients, cluster analysis techniques, and digital computers allows a polythetic approach to biostratigraphy. The approach is free of circular and a priori reasoning in that it is established that assemblage zones (major clusters in a dendrogram) are present before the biostratigraphic utility of various taxa for the recognition of the zones is determined. A measure for determining the biostratigraphic fidelity of a species for established zones is proposed. Published data on the distribution of ostracodes and foraminifers from the Eocene and Oligocene of Mississippi and Alabama are used to demonstrate a method of using coefficients and clustering in establishing a zonation.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1970)81[3237:BCACIB]2.0.CO;2","usgsCitation":"Hazel, J.E., 1970, Binary coefficients and clustering in biostratigraphy: Bulletin of the Geological Society of America, v. 81, no. 11, p. 3237-3252, https://doi.org/10.1130/0016-7606(1970)81[3237:BCACIB]2.0.CO;2.","productDescription":"16 p.","startPage":"3237","endPage":"3252","costCenters":[],"links":[{"id":392948,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alabama, Mississippi","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.593505859375,\n              30.192618218499273\n            ],\n            [\n              -88.934326171875,\n              30.32547125932808\n            ],\n            [\n              -88.79150390625,\n              30.268556249047727\n            ],\n            [\n              -88.35205078124999,\n              30.334953881988564\n            ],\n            [\n              -88.13232421875,\n              30.268556249047727\n            ],\n            [\n              -87.95654296875,\n              30.65681556429287\n            ],\n            [\n              -87.901611328125,\n              30.183121842195515\n            ],\n            [\n              -87.374267578125,\n              30.278044377800153\n            ],\n            [\n              -87.34130859375,\n              30.65681556429287\n            ],\n            [\n              -87.57202148437499,\n              30.95876857077987\n            ],\n            [\n              -84.96826171874999,\n              30.977609093348686\n            ],\n            [\n              -85.067138671875,\n              31.23159167205059\n            ],\n            [\n              -84.979248046875,\n              31.59725256170666\n            ],\n            [\n              -85.067138671875,\n              31.812229022640704\n            ],\n            [\n              -84.979248046875,\n              32.12910537866883\n            ],\n            [\n              -84.8583984375,\n              32.26855544621476\n            ],\n            [\n              -84.957275390625,\n              32.45415593941475\n            ],\n            [\n              -85.078125,\n              32.63937487360669\n            ],\n            [\n              -85.58349609375,\n              35.02099970111467\n            ],\n            [\n              -90.3076171875,\n              35.03899204678081\n            ],\n            [\n              -90.626220703125,\n              34.77771580360469\n            ],\n            [\n              -90.76904296874999,\n              34.46127728843705\n            ],\n            [\n              -91.1865234375,\n              34.016241889667015\n            ],\n            [\n              -91.329345703125,\n              33.669496972795535\n            ],\n            [\n              -91.25244140624999,\n              32.76880048488168\n            ],\n            [\n              -91.065673828125,\n              32.29641979896909\n            ],\n            [\n              -91.73583984374999,\n              30.95876857077987\n            ],\n            [\n              -89.813232421875,\n              30.95876857077987\n            ],\n            [\n              -89.93408203124999,\n              30.675715404167743\n            ],\n            [\n              -89.593505859375,\n              30.192618218499273\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"81","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Hazel, Joseph E.

The amount of air measured in glasses from nine upper Tertiary ash-flow sheets in the western United States ranges from 0.033 to 13 ppm; median is about 1 ppm. These values are very small compared with the total amounts of volatiles which probably were incorporated during welding. The data strongly suggest that large volumes of air are not incorporated by ash flows during their eruption and lateral movement.</p></div>","language":"English","publisher":"Geological Society of

Allanite porphyroblasts develop by replacement of biotite, probably in the presence of emanations from the rare earth-rich and thorium-rich Silver Plume Granite. The largest allanite crystals are made up of nearly isotropic (metamict) cores and birefringent (recrystallized) rims. Smaller crystals are made up exclusively of birefringent material. The maximum birefringence is shown to be that expectable in allanite of Late Cretaceous to early Tertiary age. As plotted on maps, the birefringence increases, and the thorium and uranium contents of the allanite decrease toward a Laramide stock. The variation in birefringence is, therefore, largely relatable to variations in the post-Laramide radiation dosage brought about by differences in the amounts of uranium and thorium lost during recrystallization. The recrystallized allanite is itself partly replaced by epidote which characteristically occurs as a border between allanite and biotite.</p><p>Total rare-earth oxides for the eight samples of allanite analyzed range from 17.5 to 21.3 percent by weight. In 13 samples, thorium ranged from 0.50 to 1.14 percent by weight, and uranium from 54 to 158 parts pparts per million.
