Sieved bulk-sediment fractions and pan concentrates were created from the original samples collected from wadis in the two quadrangles. A semiquantitative 30-element spectrographic analysis was completed on both the sieved bulk-sediment fraction and the pan concentrate of each sample. The results were statistically analyzed in an attempt to identify anomalous regions. Anomaly threshold values were calculated for most elements; the threshold value of an element in a data set is defined as the geometric mean value plus two standard deviations. \r\n\r\nThe Bald al Jimalah West tin-tungsten deposit (MODS 02661) in the southern part of the Al Jurdhawiyah quadrangle was identified by one pan-concentrate sample containing anomalous concentrations of tin and tungsten. Samples near the Bald al Jimalah East ancient lead-zinc-silver mines (MODS 00960) contain strongly anomalous concentrations of tin and lead and to a lesser extent of tungsten and copper. Both of these regions and other regions containing anomalous concentrations of certain elements are recommended for additional studies.

Chemical differences between the Ruby and Mariano Lake deposits are consistent with the interpretation that the Ruby deposit has been more affected by post-mineralization oxidizing solutions than has the Mariano Lake deposit.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83818","usgsCitation":"Pierson, C.T., Spirakis, C., and Robertson, J., 1983, Comparison of abundances of chemical elements in mineralized and unmineralized sandstone of the Brushy Basin Member of the Morrison Formation, Smith Lake District, Grants uranium region, New Mexico: U.S. Geological Survey Open-File Report 83-818, 47 p. :ill. ;28 cm., https://doi.org/10.3133/ofr83818.","productDescription":"47 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":153322,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0818/report-thumb.jpg"},{"id":50002,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0818/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d489","contributors":{"authors":[{"text":"Pierson, C.

The data for each station consist of scalar electromagnetic measurements at descrete frequencies for two-orthogonal magnetic and electric field pairs. Observations spaced about 5-km apart indicate resistivities in the range of 100-700 ohm-m for the unweathered Tertiary volcanic rocks to a depth of 200 to 500 m. Beneath this zone the data indicate resistivities in the range of 10-100 ohm-m that suggest the existence of an older volcanic rock unit. The less resistive unit appears to be displaced upward beneath Turtle Mountain, an area bounded to the northeast and southwest by mapped Basin and Range faults, and bounded to the southeast by an unmapped fault of older origin that trends northeast. Lateral changes in the resistivity of the two main geoelectric layers result in lowered resistivity in an area of known hot-springs near the confluence of the Gila and San Francisco Rivers, as well as along a north-south trending zone located on the east flank of Turtle Mountain, about 5-km (3-mi) west-northwest of the hot springs. This second anomaly is at a probable depth of 400-500 m and is interpreted to indicate a buried fault or fracture zone.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr83815","usgsCitation":"Klein, D.P., and Baer, M.J., 1983, Geoelectric structure of the Gila-San Francisco Wilderness Area, Graham and Greenlee Counties, Arizona, from audio-magnetotelluric data: U.S. Geological Survey Open-File Report 83-815, 109 p., https://doi.org/10.3133/ofr83815.","productDescription":"109 p.","costCenters":[],"links":[{"id":406098,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_14236.htm","linkFileType":{"id":5,"text":"html"}},{"id":49135,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0815/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":152182,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0815/report-thumb.jpg"}],"country":"United States","state":"Arizona","county":"Graham County, Greenlee County","otherGeospatial":"Gila-San Francisco Wilderness Area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -109.566,\n              33.076\n            ],\n            [\n              -109.32,\n              33.076\n            ],\n            [\n              -109.32,\n              32.833\n            ],\n            [\n              -109.566,\n              32.833\n            ],\n            [\n              -109.566,\n              33.076\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1de4b07f02db6a9b4e","contributors":{"authors":[{"text":"Klein, D.

Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having a weak to moderate self-potential effect extend downdip from two discontinuously exposed, parallel ridges of mineralized quartzite. Crone electromagnetic data were quantitatively interpreted using characteristic parameter lines adapted for use at 1830 and 5010 Hz, the frequencies employed at Umm ar Rummf. Depths to the top of the conductors were computed to be from 20 to 40 m or about the thickness of the oxidized zone, which behaves as a variably conductive overburden. Both tabular conductors can also be traced geophysically to the north and south of the copper-bearing outcrops. The association of the geophysical anomalies with copper-mineralized rocks has been proved by drilling. \r\n\r\nReconnaissance MAXMIN electromagnetic profiles across the target using a wide coil separation show broad, low-amplitude anomalies that may indicate mineralized rocks at depth, and reconnaissance ground-magnetic profiles show strong total-field intensity anomalies associated with basaltic dikes of probable Tertiary age.

Compilation of available information on the distribution, composition, and ages of these rocks indicates the presence of six major and six minor plutonic belts.</p><p>From west to east, the major belts are: the Fairweather-Baranof belt of early to mid-Tertiary granodiorite; the Muir-Chichagof belt of mid-Cretaceous tonalite and granodiorite; the Admiralty-Revillagigedo belt of porphyritic granodiorite, quartz diorite, and diorite of probable Cretaceous age; the Klukwan-Duke belt of concentrically zoned or Alaskan-type ultramafic-mafic plutons of mid-Cretaceous age within the Admiralty-Revillagigedo belt; the Coast Plutonic Complex sill belt of tonalite of unknown, but perhaps mid-Cretaceous, age; and the Coast Plutonic Complex belt I of early to mid-Tertiary granodiorite and quartz monzonite.</p><p>The minor belts are distributed as follows: the Glacier Bay belt of Cretaceous and(or) Tertiary granodiorite, tonalite, and quartz diorite lies within the Fair-weather-Baranof belt; layered gabbro complexes of inferred mid-Tertiary age lie within and are probably related to the Fairweather-Baranof belt; the Chilkat-Chichagof belt of Jurassic granodiorite and tonalite lies within the Muir-Chichagof belt; the Sitkoh Bay alkaline, the Kendrick Bay pyroxenite to quartz monzonite, and the Annette and Cape Fox trondhjemite plutons, all interpreted to be of Ordovician(?) age, together form the crude southern southeastern Alaska belt within the Muir-Chichagof belt; the Kuiu-Etolin mid-Tertiary belt of volcanic and plutonic rocks extends from the Muir-Chichagof belt eastward into the Admiralty-Revillagigedo belt; and the Behm Canal belt of mid- to late Tertiary granite lies within and next to Coast Plutonic Complex belt II. In addition, scattered mafic-ultramafic bodies occur within the Fairweather-Baranof, Muir-Chichagof, and Coast Plutonic Complex belts I and II. Palinspastic reconstruction of 200 km of right-lateral movement on the Chatham Strait fault does not significantly change the pattern of the major belts but does bring parts of the minor mid-Tertiary and Ordovician(?) belts closer together.</p><p>The major belts are related to the stratigraphic-tectonic terranes of Berg, Jones, and Coney (1978) as follows: the Fairweather-Baranof belt is largely in the Chugach, Wrangell (Wrangellia), and Alexander terranes; the Muir-Chichagof belt is in the Alexander and Wrangell terranes; the Admiralty-Revillagigedo belt is in the Gravina and Taku terranes; the Klukwan-Duke belt is in the Gravina, Taku, and Alexander terranes; the Coast Plutonic Complex sill belt is probably between the Taku and Tracy Arm terranes; and the Coast Plutonic Complex belts I and II are in the Tracy Arm and Stikine terranes.</p><p>Significant metallic-mineral deposits are spatially related to certain of these belts, and some deposits may be genetically related. Gold, copper, and molybdenum occurrences may be related to granodiorites of the Fairweather-Baranof belt. Magmatic copper-nickel deposits occur in the layered gabbro within that belt. The Juneau gold belt, which contains gold, silver, copper, lead, and zinc occurrences, parallels and lies close to the Coast Plutonic Complex sill belt; iron deposits occur in the Klukwan-Duke belt; and porphyry molybdenum deposits occur in the Behm Canal belt.</p><p>The Muir-Chichagof belt of mid-Cretaceous age and the Admiralty-Revillagigedo belt of probable Cretaceous age are currently interpreted as possible magmatic arcs associated with subduction events. In general, the other belts of intrusive rocks are spatially related to structural discontinuities, but genetic relations, if any, are not yet known. The Coast Plutonic Complex sill belt is probably related to a post-Triassic, pre-early Tertiary suture zone that nearly corresponds to the boundary between the Tracy Arm and Taku terranes. The boundary between the Admiralty-Revillagigedo and Muir-Chichagof belts coincides nearly with the Seymour Canal-Clarence Strait lineament and also is probably a major post-Triassic suture.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/MEM159-p171","usgsCitation":"Brew, D.A., and Morrell, R.P., 1983, Intrusive rocks and plutonic belts of southeastern Alaska, U.S.A: GSA Memoirs, v. 159, p. 171-194, https://doi.org/10.1130/MEM159-p171.","productDescription":"24 p.","startPage":"171","endPage":"194","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":373716,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Southeastern Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -135.087890625,\n              59.5343180010956\n            ],\n            [\n              -138.076171875,\n              58.53959476664049\n            ],\n            [\n              -133.2421875,\n              54.16243396806779\n            ],\n            [\n              -129.814453125,\n              55.27911529201561\n            ],\n            [\n              -135.087890625,\n              59.5343180010956\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"159","noUsgsAuthors":false,"publicationDate":"1983-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Brew, David A. dbrew@usgs.gov","contributorId":3244,"corporation":false,"usgs":true,"family":"Brew","given":"David","email":"dbrew@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":786244,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morrell, Robert P.","contributorId":19157,"corporation":false,"usgs":true,"family":"Morrell","given":"Robert","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":786245,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Four agricultural areas, two low-density residential areas, and Chekika Hammock State Park were investigated. The effects of land use on the groundwater were minimal in all areas; only iron , which occurs naturally in high concentrations in the Everglades, exceeded potable groundwater standards. Potassium and nitrate concentrations in certain samples increased over background concentrations in the agricultural areas. Groundwater at Chekika Hammock State Park and at a citrus grove is contaminated by brackish water flowing from an artesian well. The soil at the agricultural areas had higher concentrations of chromium, copper, and manganese than at the two residential areas or at Chekika Hammock State Park. One residential area (Coopertown) had the highest concentrations of lead and zinc and detectable polychlorinated biphenyls. Chlorinated-hydrocarbon insecticide residues in soil at three agricultural areas were higher than background concentrations.

Metal concentrations were evaluated with respect to area, species, sex and age groups.  Metal concentrations in Peromyscus from the proposed mine site were not different from those collected in a third area where no mine or deposit exists.  This is probably due to the 30 m of glacial material over the proposed mine site deposit.  A statistical interaction between area, species, sex and age was observed for zinc and copper concentrations in small mammals we examined.  Peromyscus from the mine site had consistently higher metal concentrations than Peromyscus from the control site.  Greater total body cadmium and lead concentrations in adult?compared with juvenile?Peromyscus collected at the mine site suggests age-dependent accumulation of these toxic metals.  Microtus did not exhibit this age-related response, and responded to other environmental metals more erratically and to a lesser degree.  Differences in the response of these two species to environmental metal exposure may be due to differences in food habits.  Nickel, mercury and arsenic concentrations in small mammals from the mine site were not different from controls.  Heavy metal concentrations are also presented for Sorex cinereus, Blarina brevicauda and Zapus hudsonicus without respect to age and sex cohorts. Peromyscus may be a potentially important species for the monitoring of heavy metal pollution.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Pollution (Series A)","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0143-1471(82)90098-8","collaboration":"2781_Smith.pdf","usgsCitation":"Smith, G.J., and Rongstad, O., 1982, Small mammal-heavy metal concentrations from mined and control sites: Environmental Pollution (Series A), v. 28, no. 2, p. 121-134, https://doi.org/10.1016/0143-1471(82)90098-8.","productDescription":"121-134","startPage":"121","endPage":"134","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":18415,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/0143-1471(82)90098-8","linkFileType":{"id":5,"text":"html"}},{"id":196674,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e482ae4b07f02db4e75a4","contributors":{"authors":[{"text":"Smith, G.
