The plutonic rocks have an aggregate area of about 1,200 square miles and their composition, distribution, and possible petrogenesis are discussed for the first time in this report. \r\n\r\nField, petrographic and chemical data supported by K/Ar age dating indicate the plutonic rocks are divisible into two suites differing in age, location, and composition. The western plutons are mid-Cretaceous (~100 m.y.) in age and consist of a heterogeneous assemblage of monzonite, syenite, quartz monzonite. Associated with these granitic rocks is a group of alkaline sub-silicic rocks that forma belt of intrusive complexes extending for a distance of at least 180 miles from west-central Alaska to the Bering Sea. The complex at Granite Mountain shows a rare example of zoning from an alkaline rim to a quartz-bearing core. The occurrence of a similar complex at Cape Dezhnev on the easternmost tip of Siberia suggests the alkaline province may extend into Siberia. The easternmost plutons are Late Cretaceous (180 m.y.) in age and composed primarily of granodiorite and quartz monzonite similar to calc-alkaline plutons found throughout the North America Cordillera.\r\n\r\nThe plutons are epizonal and intrude deformed but unmetamorphosed Lower Cretaceous andesitic volcanics and volcanic graywacke which constitute the highly mobile Yukon-Koyukuk volcanogenic province of west-central Alaska. No older rocks have been found within the confines of this vast tract; the occurrence of a bounding ophiolite sequence has lead to the suggestion that the province was formed by large-scale rifting and is underlain by oceanic crust. \r\n\r\nThe possibility of no juvenile sialic crust over much of the area suggests that the potassium-rich magma now represented by the alkaline rocks originated in the mantle. The distribution of the alkaline rocks appears to be related to regional structural features, particularly the boundary between the Mesozoic volcanogenic province of west-central Alaska and the thrust-faulted province of metamorphic-plutonic and sedimentary rocks of Paleozoic and Precambrian age that forms the eastern Seward Peninsula. This boundary may have been a zone of structural weakness along which alkaline magma was generated. Modal and chemical trends suggest that the potassium-rich magma influenced the composition of more granitic magmas forming at higher levels. The latter may have been forming as a result of anatexis of andesite and mixing of mantle-derived mafic magma. The result is the heterogeneous assemblage of generally potassium-rich plutonic rocks that forms the west end of the Hogataza plutonic belt.\r\n\r\nThe loci of magmatism in west-central Alaska shifted east in Late Cretaceous time and the eastern plutons show only local signs of potassium enrichment. They are compositionally homogeneous and differences within plutons appear due to local contamination.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr71210","usgsCitation":"Miller, T.P., 1970, Petrology of the Plutonic Rocks of west-central Alaska: U.S. Geological Survey Open-File Report 71-210, xi, 132, [2] leaves :ill., maps ;27 cm.; 136 p., https://doi.org/10.3133/ofr71210.","productDescription":"xi, 132, [2] leaves :ill., maps ;27 cm.; 136 p.","costCenters":[],"links":[{"id":106510,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_8615.htm","linkFileType":{"id":5,"text":"html"},"description":"8615"},{"id":153233,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1971/0210/report-thumb.jpg"},{"id":49672,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1971/0210/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49673,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1971/0210/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49674,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1971/0210/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49675,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1971/0210/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db68668e","contributors":{"authors":[{"text":"Miller, Thomas P. tmiller@usgs.gov","contributorId":4183,"corporation":false,"usgs":true,"family":"Miller","given":"Thomas","email":"tmiller@usgs.gov","middleInitial":"P.","affiliations":[{"id":121,"text":"Alaska Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":182117,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

When properly impacted against a stiff material the device measures the amount of rebound of a spring-loaded hammer, with the rebound of the hammer being directly proportional to the strength of the material tested. Application of this instrument to rock, specifically water-saturated zeolitized tuff, is demonstrated through a set of correlation diagrams that relate Schmidt hammer rebound values, obtained from core samples and from the sites where samples were taken, to physical properties measured on rock samples in the laboratory. The properties include compressive strength, compressional and shear velocities, and dynamic and static Young's shear and bulk moduli. The correlation diagrams apply only to zeolitized tuff of the type found at the Nevada Test Site in its natural state (freshly excavated). These diagrams enable the user of the L-type Schmidt hammer to immediately obtain values of physical properties of such rocks in place, a convenience desirable where conventional sampling is not feasible or is impossible, and when results are required on short notice. The charts apply to L-type hammers that are calibrated to a nominal rebound value of 74. Calibration is made on a 35-pound-(16-kg-) test anvil with a steel-hardened test surface of Brinell hardness = 500 kg/mm<sup>2</sup><span id=\"_mce_caret\" data-mce-bogus=\"1\" data-mce-type=\"format-caret\">.</span></p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr70117","usgsCitation":"Ege, J.R., Miller, D.R., and Danilchik, W., 1970, Schmidt hammer test method for field determination of physical properties of zeolitized tuff: U.S. Geological Survey Open-File Report 70-117, iv, 37 p., https://doi.org/10.3133/ofr70117.","productDescription":"iv, 37 p.","costCenters":[],"links":[{"id":498187,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0117/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":147091,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0117/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd364","contributors":{"authors":[{"text":"Ege, John R.","contributorId":69534,"corporation":false,"usgs":true,"family":"Ege","given":"John","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":167869,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, Danny R.","contributorId":75536,"corporation":false,"usgs":true,"family":"Miller","given":"Danny","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":167871,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Danilchik, Walter","contributorId":70390,"corporation":false,"usgs":true,"family":"Danilchik","given":"Walter","email":"","affiliations":[],"preferred":false,"id":167870,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
