Host rocks include both mafic and felsic volcanic rocks or their volcaniclastic equivalents, silica-rich chemical sediments, and locally developed carbonate horizons. Some host rocks display variably preserved relict volcanic and (or) sedimentary textures, but the majority are metamorphic rocks having original textures and mineralogies substantially changed. In addition, many host rocks experienced significant premetamorphic chemical alteration that further obscures their origins. For these reasons, the \"Host rock lithology\" column in table 1 first lists a metamorphic rock description and them, in parentheses, suggests a possible volcanic or chemical-sediment protolith.</p>\n<p>With the exception of the Pecos mine and a subsurface deposit partially outlined by recent drilling at Jones Hill, New Mexico occurrences shown on this map do not exhibit enough of the classic features of volcanogenic massive-sulfide deposits to make their classification (or origins) unequivocal.

Map C shows outlines of those drainage basins containing samples of stream sediment and concentrate with anomalous element concentrations and also shows weighted values for each outlined basin based on the number of elements with anomalous concentrations in each stream-sediment and concentrate sample and on the degree to which these concentrations are anomalous in each sample.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf1535C","usgsCitation":"Chaffee, M.A., 1986, Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Sweetwater Roadless Area, Mono County, California and Lyon and Douglas Counties, Nevada: U.S. Geological Survey Miscellaneous Field Studies Map 1535, 2 Plates: 53.57 x 33.85 inches and 50.66 x 33.67 inches, https://doi.org/10.3133/mf1535C.","productDescription":"2 Plates: 53.57 x 33.85 inches and 50.66 x 33.67 inches","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":327191,"rank":1,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1535-C/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":327190,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1535-C/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":326381,"rank":3,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf1535C.JPG"}],"scale":"62500","country":"United States","state":"California, Nevada","county":"Douglas County, Lyon County, Mono County","otherGeospatial":"Sweetwater Roadless Area","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -119.5,38.25 ], [ -119.5,38.5 ], [ -119.25,38.5 ], [ -119.25,38.25 ], [ -119.5,38.25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db6995d2","contributors":{"authors":[{"text":"Chaffee, Maurice A. mchaffee@usgs.gov","contributorId":4047,"corporation":false,"usgs":true,"family":"Chaffee","given":"Maurice","email":"mchaffee@usgs.gov","middleInitial":"A.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":261492,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
