Ages of sized and magnetic fractions of zircon concentrates show variable degrees of discordance which seem to result from a very young disturbance that produces linear arrays in the Concordia plot. Model age calculations based on a statistically and geologically reasonable lower intercept produce very consistent internal relationships. The Pan African Orogeny, considered to be responsible for loss of radiogenic argon and strontium from minerals of many rocks, does not appear to have affected the zircon data, even though uplift had exposed the rocks of the Arabian Shield at that time. Tonalite, granodiorite, and crosscutting leucoadamellite bodies in the southern part of the An Nimas Bathylith yield ages in the time range 820-760 Ma. A narrow time range of 660 to 665 million years was indicated for ages of widely separated and compositionally different intrusive bodies all to the east of the An Nimas Bathylith. This work suggests that the younger end of the age spectrum established from regional K-Ar and Rb-Sr measurements may be underestimated, and that magmatic activity could be more episodic than previously assumed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/BF01164527","issn":"00107990","usgsCitation":"Cooper, J., Stacey, J.S., Stoeser, D., and Fleck, R., 1979, An evaluation of the zircon method of isotopic dating in the Southern Arabian Craton: Contributions to Mineralogy and Petrology, v. 68, no. 4, p. 429-439, https://doi.org/10.1007/BF01164527.","productDescription":"11 p.","startPage":"429","endPage":"439","costCenters":[],"links":[{"id":205143,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01164527"},{"id":221815,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Arabian Peninsula","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 34.53,11.8 ], [ 34.53,32.15 ], [ 60.3,32.15 ], [ 60.3,11.8 ], [ 34.53,11.8 ] ] ] } } ] }","volume":"68","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ea5be4b0c8380cd487e3","contributors":{"authors":[{"text":"Cooper, J.A.","contributorId":57005,"corporation":false,"usgs":true,"family":"Cooper","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":363228,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stacey, J.

Two networks of precise horizontal control were established in Mexicali Valley by the U.S. Geological Survey in 1977 - 1978 to measure both types of movement as they occur. These networks consisted of (1) a regional trilateration net brought into the mountain ranges west of the geothermal area from survey stations on an existing U.S. Geological Survey crustal-strain network north of the international border, and (2) a local net tied to stations in the regional net and encompassing the area of present and planned geothermal production. Survey lines in this net were selected to span areas of probable ground-surface movements in and around the geothermal area. Electronic distance measuring (EDM) instruments, operating with a modulated laser beam, were used to measure the distances between stations in both networks. The regional net was run using a highly precise long-range EDM instrument, helicopters for transportation of men and equipment to inaccessible stations on mountain peaks, and a fixed wing airplane flying along the line of sight. Precision of measurements with this complex long-range system approached 0-2 ppm of line length. The local net was measured with a medium-range EDM instrument requiring minimal ancillary equipment. Precision of measurements with this less complex system approached 3 ppm for the shorter line lengths. The detection and analysis of ground-surface movements resulting from tectonic strains or induced by geothermal fluid withdrawal is dependent on subsequent resurveys of these networks. ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geothermics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(79)90052-X","issn":"03756505","usgsCitation":"Massey, B., 1979, Regional and local networks of horizontal control, Cerro Prieto geothermal area: Geothermics, v. 8, no. 3-4, p. 275-281, https://doi.org/10.1016/0375-6505(79)90052-X.","startPage":"275","endPage":"281","numberOfPages":"7","costCenters":[],"links":[{"id":221809,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268144,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0375-6505(79)90052-X"}],"volume":"8","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a4a2e4b0e8fec6cdbbd4","contributors":{"authors":[{"text":"Massey, B.L.","contributorId":27611,"corporation":false,"usgs":true,"family":"Massey","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":363058,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The main uplift of this region began about 17 m.y. ago, with slow uplift of the central Sierra Nevada summit region at rates estimated at about 0.012 mm/yr and of western Basin and Range Province at about 0.01 mm/yr. Many Mesozoic faults of the Foothills fault system were reactivated with normal slip in mid-Tertiary time and have continued to be active with slow slip rates. Sparse data indicate acceleration of rates of uplift and faulting during the Late Cenozoic. The Basin and Range faulting appears to have extended westward during this period with a reduction in width of the Sierra Nevada. The eastern boundary zone of the Sierra Nevada has an irregular en-echelon pattern of normal and right-oblique faults. The area between the Sierra Nevada and the Walker Lane is a complex zone of irregular patterns of ho??rst and graben blocks and conjugate normal-to right- and left-slip faults of NW and NE trend, respectively. The Walker Lane has at least five main strands near Walker Lake, with total right-slip separation estimated at 48 km. The NE-trending left-slip faults are much shorter than the Walker Lane fault zone and have maximum separations of no more than a few kilometers. Examples include the 1948 and 1966 fault zone northeast of Truckee, California, the Olinghouse fault (Part III) and possibly the almost 200-km-long Carson Lineament. Historic geologic evidence of faulting, seismologic evidence for focal mechanisms, geodetic measurements and strain measurements confirm continued regional uplift and tilting of the Sierra Nevada, with minor internal local faulting and deformation, smaller uplift of the western Basin and Range Province, conjugate focal mechanisms for faults of diverse orientations and types, and a NS to NE-SW compression axis (??1) and an EW to NW-SE extension axis (??3). ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Tectonophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0040-1951(79)90271-3","issn":"00401951","usgsCitation":"Slemmons, D., Wormer, D., Bell, E., and Silberman, M., 1979, Recent crustal movements in the Sierra Nevada-Walker lane region of California-Nevada: Part i, rate and style of deformation: Tectonophysics, v. 52, no. 1-4, p. 561-570, https://doi.org/10.1016/0040-1951(79)90271-3.","startPage":"561","endPage":"570","numberOfPages":"10","costCenters":[],"links":[{"id":222214,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a95f2e4b0c8380cd81d15","contributors":{"authors":[{"text":"Slemmons, D.B.","contributorId":11763,"corporation":false,"usgs":true,"family":"Slemmons","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":364021,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wormer, D.V.","contributorId":49111,"corporation":false,"usgs":true,"family":"Wormer","given":"D.V.","email":"","affiliations":[],"preferred":false,"id":364022,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bell, E.J.","contributorId":62747,"corporation":false,"usgs":true,"family":"Bell","given":"E.J.","email":"","affiliations":[],"preferred":false,"id":364023,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Silberman, M.L.","contributorId":10013,"corporation":false,"usgs":true,"family":"Silberman","given":"M.L.","affiliations":[],"preferred":false,"id":364020,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Flushing the charged greensand filter with water does not cause significant release of cations back into solution, suggesting that polluted greensand might be disposed of at landfill sites without endangering the quality of either ground or surface water. ?? 1979 Springer Verlag New York Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF02380510","issn":"09430105","usgsCitation":"Spoljaric, N., and Crawford, W., 1979, Removal of contaminants from landfill leachates by filtration through glauconitic greensands: Environmental Geology, v. 2, no. 6, p. 359-363, https://doi.org/10.1007/BF02380510.","startPage":"359","endPage":"363","numberOfPages":"5","costCenters":[],"links":[{"id":222416,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205233,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02380510"}],"volume":"2","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa729e4b0c8380cd8526a","contributors":{"authors":[{"text":"Spoljaric, N.","contributorId":12625,"corporation":false,"usgs":true,"family":"Spoljaric","given":"N.","email":"","affiliations":[],"preferred":false,"id":363599,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crawford, W.A.","contributorId":103009,"corporation":false,"usgs":true,"family":"Crawford","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":363600,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The rhombic pattern is optimal when the targets are known to have a preferred orientation. Situations can also be found where a rectangular pattern is as efficient as the rhombic pattern. A triangular or square drilling pattern should be used when the orientations of the targets are unknown. The way in which the optimum hole spacing varies as a function of (1) the cost of drilling, (2) the value of the targets, (3) the shape of the targets, (4) the target occurrence probabilities was determined for several examples.

Topography is rugged, with approximately 400 feet of relief between the boundary ridge tops and the valley floor. The water-retention structures (a dry floodwater- retention structure and a 43-acre reservoir) are to provide recreation and flood protection for the basin.</p>\n<p>Streamflow, springflow, precipitation, and groundwater levels were monitored at several sites to describe the hydrologic system. Streamflow is fairly constant at base flow, but rapid changes in discharge occur during periods of snowmelt or heavy rain; recession to base-flow discharge following these events is rapid. Surface runoff is a significant contributor to Streamflow only 10 percent of the time.</p>\n<p>The mean annual hydrologic budget for water years 1968-72 shows that of the 32.5 inches of precipitation on the basin, 6.4 inches left as runoff and 25.9 inches as evapotranspiration; ground-water storage increased an average of 0.2 inches per year.</p>\n<p>The water is a hard calcium magnesium bicarbonate type. Concentrations of major constituents in ground water and streams at base flow are similar, but concentrations in the stream generally decrease during periods when surface runoff contributes to Streamflow. Dissolved-oxygen concentrations in the stream are generally lowest during the summer; nighttime lows are generally between 7 and 8 milligrams per liter and daily maximums between 11 and 12.5 milligrams per liter. Diurnal water-temperature fluctuations of several degrees are common in streams during summer; daily maximum water temperatures as high as 26&deg;C have been measured in some areas, but temperatures this high seldom persist for more than 2 hours. Estimates of mean annual total phosphorus and total nitrogen loads during 1967-74 fall within the ranges of 0.02 to 0.07 and 0.4 to 0.8 tons per square mile, respectively; 70 to 80 percent of the total phosphorus and 35 to 55 percent of the total nitrogen are transported during periods when surface runoff contributes to Streamflow.</p>\n<p>Mean annual suspended-sediment loads during 1968-74 range from 13 to 60 tons per square mile, with 74 to 86 percent of the total transported during periods when surface water contributes to streamflow. These sediment loads are at the low end of the range previously reported for streams in the \"Driftless Area\".</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7995","usgsCitation":"Kammerer, P.A., and Sherrill, M.G., 1979, Hydrology and water quality in the Nederlo Creek Basin, Wisconsin, before construction of two water-retention structures: U.S. Geological Survey Water-Resources Investigations Report 79-95, v, 34 p., https://doi.org/10.3133/wri7995.","productDescription":"v, 34 p.","numberOfPages":"41","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":414907,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35374.htm","linkFileType":{"id":5,"text":"html"}},{"id":123633,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1979/0095/report-thumb.jpg"},{"id":56783,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1979/0095/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Wisconsin","otherGeospatial":"Nederlo Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.01554870605469,\n              43.308941276170124\n            ],\n            [\n              -91.01554870605469,\n              43.40429919674392\n            ],\n            [\n              -90.86242675781249,\n              43.40429919674392\n            ],\n            [\n              -90.86242675781249,\n              43.308941276170124\n            ],\n            [\n              -91.01554870605469,\n              43.308941276170124\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db688073","contributors":{"authors":[{"text":"Kammerer, Phil A.

Occupation of the marine environment by mammals probably carried physiological constraints for single-young pregnancies thereby limiting all species to low intrinsic rates of population increase. As such, species subjected to high mortality rates from predation or other natural disturbances became extinct; those that survived probably were largely resource limited. In view of this scenario it is suggested that stable populations of marine mammals can be maintained at high levels without being manipulated in most communities. Exploitation probably constitutes a rather dramatic environmental change to marine mammals consequently subjecting them to selective forces fundamentally different from many of those under the influence of which they evolved.<br data-mce-bogus=\"1\"></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/f79-140","usgsCitation":"Estes, J.A., 1979, Exploitation of marine mammals: r-selection of K-strategists?: Journal of the Fisheries Research Board of Canada, v. 36, p. 1209-1217, https://doi.org/10.1139/f79-140.","productDescription":"9 p.","startPage":"1209","endPage":"1217","numberOfPages":"9","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130124,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699e1c","contributors":{"authors":[{"text":"Estes, J.
