Earthquake-related changes in tilt have been simultaneously observed on up to four independent instruments. At earthquake distances greater than 10 earthquake source dimensions, there are few clear indications of tilt change. For the four instruments with the longest records (>10 months), 26 earthquakes have occurred since July 1973 with at least one instrument closer than 10 source dimensions and 8 earthquakes with more than one instrument within that distance. Precursors in tilt direction have been observed before more than 10 earthquakes or groups of earthquakes, and no similar effect has yet been seen without the occurrence of an earthquake.","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.186.4168.1031","issn":"00368075","usgsCitation":"Johnston, M., and Mortensen, C., 1974, Tilt precursors before earthquakes on the San Andreas fault, California: Science, v. 186, no. 4168, p. 1031-1034, https://doi.org/10.1126/science.186.4168.1031.","productDescription":"4 p.","startPage":"1031","endPage":"1034","costCenters":[],"links":[{"id":220878,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -124.45666847071621,\n              42.01984851212089\n            ],\n            [\n              -125.16966073400368,\n              40.34354343643049\n            ],\n            [\n              -123.27167044267902,\n              36.56383126641184\n            ],\n            [\n              -118.02584394627357,\n              32.41432931769626\n            ],\n            [\n              -114.67012404096481,\n              32.57112197935383\n            ],\n            [\n              -114.14712625758764,\n              34.23963061224003\n            ],\n            [\n              -114.33539006324236,\n              34.89289036617578\n            ],\n            [\n              -119.93892948906924,\n              38.960055495084276\n            ],\n            [\n              -119.9821581107169,\n              42.06558960257587\n            ],\n            [\n              -124.45666847071621,\n              42.01984851212089\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"186","issue":"4168","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb38be4b08c986b325e58","contributors":{"authors":[{"text":"Johnston, M.J.S. 0000-0003-4326-8368","orcid":"https://orcid.org/0000-0003-4326-8368","contributorId":104889,"corporation":false,"usgs":true,"family":"Johnston","given":"M.J.S.","affiliations":[],"preferred":false,"id":360169,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mortensen, C.E.","contributorId":91503,"corporation":false,"usgs":true,"family":"Mortensen","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":360168,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During Late Triassic time, large fault basins formed within the Gulf of Maine and probably beneath Georges Bank. The fault basins and a possible major northeast-trending fault zone beneath the northern part of the bank probably formed as a result of the opening Atlantic during the Mesozoic. Nonmarine sediments, associated with mafic flows and intrusive rocks, were deposited in the fault basins as they formed. The upper surface of the Triassic and pre-Triassic rocks that comprise basement is an unconformity that makes up much of the bottom of the Gulf of Maine. Depth to the basement surface beneath the gulf differ greatly because of fluvial erosion in Tertiary time and glacial erosion in Pleistocene time. Beneath the northern part of Georges Bank the basement surface is smoother and slopes southward. Prominent valleys, cut before Late Cretaceous time, are present beneath this part of the bank.</p><p>Cretaceous, Tertiary, and possibly Jurassic times were characterized by episodes of coastal-plain deposition and fluvial erosion. During this time a very thick wedge of sediment, mostly of Jurassic(?) and Cretaceous ages, was deposited on the shelf. Major periods of erosion took place at the close of the Cretaceous and during the Pliocene. Fluvial erosion during the Pliocene removed much of the coastal-plain sedimentary wedge and formed the Gulf of Maine.</p><p>Pleistocene glaciers eroded all but a few remnants of the coastal-plain sediments within the gulf and deposited a thick section of drift against the north slope of Georges Bank and a thin veneer of outwash on the bank. Marine sediments were deposited in the basins of the Gulf of Maine during the retreat of the last ice and the postglacial rise in sea level.</p>","language":"English","publisher":"American Association of Petroleum Geologists","doi":"10.1306/83D91BC3-16C7-11D7-8645000102C1865D","usgsCitation":"Oldale, R.N., Hathaway, J., Dillon, W.P., Hendricks, J.D., and Robb, J.M., 1974, Geophysical observations on northern part of Georges Bank and adjacent basins of Gulf of Maine: AAPG Bulletin, v. 58, no. 12, p. 2411-2427, https://doi.org/10.1306/83D91BC3-16C7-11D7-8645000102C1865D.","productDescription":"17 p.","startPage":"2411","endPage":"2427","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":292701,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Georges Bank, Gulf Of Maine","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -69.0,40.0 ], [ -69.0,42.0 ], [ -60.0,42.0 ], [ -60.0,40.0 ], [ -69.0,40.0 ] ] ] } } ] }","volume":"58","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f5b653e4b09d12e0e8e6ce","contributors":{"authors":[{"text":"Oldale, R.

These offset plutons place severe constraints on the amount and rate of movement along the McKinley segment since the beginning of the Oligocene Epoch. The 38-km displacement indicates an average rate of 0.1 cm/yr if movement began immediately after crystallization in early Oligocene time or an average rate of 0.4 cm/yr if movement began 10 m.y. ago in late Miocene time. These rates, however, are considerably less than Holocene movement rates measured along the fault further to the east, which suggests that the Holocene displacement rate is greater than the pre-Holocene rate or that right-lateral movement along the fault may diminish to the west.</span></p>","language":"English","publisher":"GSW","doi":"10.1130/0016-7606(1974)85<1883:OPAHOM>2.0.CO;2","usgsCitation":"Reed, B.L., and Lanphere, M.A., 1974, Offset plutons and history of movement along the McKinley segment of the Denali Fault system, Alaska: GSA Bulletin, v. 85, no. 12, p. 1883-1892, https://doi.org/10.1130/0016-7606(1974)85<1883:OPAHOM>2.0.CO;2.","productDescription":"10 p.","startPage":"1883","endPage":"1892","costCenters":[],"links":[{"id":356242,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Reed, Bruce L.","contributorId":19928,"corporation":false,"usgs":true,"family":"Reed","given":"Bruce","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":741506,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lanphere, Marvin A. alder@usgs.gov","contributorId":2696,"corporation":false,"usgs":true,"family":"Lanphere","given":"Marvin","email":"alder@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":741507,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

He wrote that no known intermediate forms, fossil or living, bridge the \"enormous gaps between any two of the three lineages,\" and therefore treated each as a separate subphylum. These subphyla are (i) the subphylum Aculifera Hatscheck 1891, containing only the class Aplacophora, derived from the most primitive ancestors of the Mollusca; (ii) the subphylum Placophora von Jhering 1876, containing only the class Polyplacophora, and emphasizing the pseudometamerism of its more advanced premollusk ancestor; and (iii) the subphylum Conchifera Gegenbaur 1878, containing the Monoplacophora and the other classes derived from it.</span></p><p><span>We point out that the Polyplacophora may be derived from the Monoplacophora instead of a more primitive ancestral stock. We also suggest that the Conchifera can be separated into two major lineages, each worthy of the rank of subphylum. The fossil record indicates that the Monoplacophora gave rise to the Gastropoda, Cephalopoda, Rostroconchia, and possibly Polyplacophora, and that the Pelecypoda and Scaphopoda are derived from the Rostroconchia. These last three classes thus form a lineage that diverged from the Monoplacophora in the Early Cambrian. They emphasized a shell form that in all groups is primitively open at both ends, allowing the gut to remain relatively straight, with an anterior mouth and posterior anus. They became burrowing (infaunal) deposit or filter feeders. We coin the term Diasoma (through-body) for the subphylum containing these three classes (Rostroconchia, Pelecypoda, and Scaphopoda). The remaining three classes (Monoplacophora, Gastropoda, and Cephalopoda) emphasize a conical univalved shell, usually twisted into a spiral. The relatively small single aperture forces the anus to lie close to the mouth, and the gut is bent into a \"U.\" Most are surface-dwelling (epifaunal) grazers or carnivores. We coin the name&nbsp;<i>Cyrtosoma</i>&nbsp;(hunchback-body) for the subphylum containing these three classes.

The 1973 population was estimated at 1,450 ± 30 pairs, of which 713 were on the western shore and 737 on the eastern shore. A small percentage of nonbreeders (possibly 2-5 percent) may be included in this estimate. Only 31.7 percent of the population was nesting in trees; the remaining birds utilized duck blinds (28.7 percent), channel markers (21.8 percent), and miscellaneous man-made structures (17.8 percent). The geographical distribution of nesting ospreys has quite likely changed during the last several decades as suitable artificial nesting sites have become more available. Furthermore, limited evidence suggests that birds nesting on the man-made sites were more successful than those nesting in trees.

The chert is in green to gray mudstone, about 8 m beneath a conspicuous gray and yellow zeolitic tuff. The bedded chert contains molds of saline minerals and it grades southward and marginward into nodular chert. The nodular chert is of two varieties: relatively large lobate nodules that have greenish-brown interiors and abundant saline crystal molds, and relatively small lobate nodules that have gray interiors and a surface reticulation. The latter variety is the so-called snakeskin agate prized by lapidaries. Both nodular varieties characteristically have a thin white rind. The cherts are similar, if not identical, to cherts reported from Quaternary lacustrine deposits in eastern Africa and from Pleistocene to Jurassic lacustrine deposits in Wyoming.

Both are characterized by pale-red or purplish-medium-gray siltstone with abundant bedding-surface markings, and both contain scarce to abundant amounts of evenly or lenlicularly laminated limestone or silty limestone. Both units are lithologically unique in their respective areas of occurrence, and both are known to be widely distributed. Several thousand feet of dominantly detrital rocks occur above the Johnnie Formation in southern Nevada and the McCoy Creek Group in east-central Nevada. These detrital rocks consist of quartzite and siltstone in southern Nevada (the Stirling Quartzite, Wood Canyon Formation, and Zabriskie Quartzite) and dominantly quartzite (the Prospect Mountain Quartzite) in cast-central Nevada. Study in areas between southern and east-central Nevada indicates that the Stirling, Wood Canyon, and Zabriskie Formations change facies to the north and become lithologically similar to one another.

Magnetic anomalies show the areal distribution of rocks containing magnetite. Aeroradiometric anomalies in the Piedmont and Coastal Plain provinces are directly related to the K<sub>2</sub>O&nbsp;content of the formations. In the crystalline rocks of the Piedmont this is reflected in their muscovite and microcline content, whereas in the Coastal Plain province it is related to the glauconite content of the Aquia Formation. Locally, in the crystalline rocks of the Piedmont, uranium- and thorium-bearing mineral content is of greater importance than K<sub>2</sub>O-bearing mineral content in producing aeroradiometric anomalies. The region also is characterized by (1) a northern gravity high, (2) a southern gravity high presumed to be caused by mafic rocks, and (3) an intervening zone characterized by low gravity relief and underlain by schist and gneiss.

Effluents discharged to the aquifer have contained high concentrations of both organic (detergents, oil and grease, phenols, humic compounds, and others) and inorganic (chromium, chloride, phosphates, and others) substances. The concentration of dissolved organic carbon (DOC), as determined by a wet combustion technique, has been shown to be a definitive parameter in identifying ground water affected by waste disposal. DOC concentrations ranged from 0.1 to 0.8 milligram per liter in the nondegraded ground water and exceeded 6 milligrams per liter in the ground water affected by the waste discharge.</p><p>The general distribution of DOC in the degraded ground water has been defined both areally and vertically. The vertical distribution of DOC and other constituents indicates that two plumes of degraded water occur at different depths. A comparison of the areal distribution of DOC and detergents (as MBAS) suggests that some organic compounds may have been adsorbed by the aquifer sediments.</p>","language":"English","publisher":"National Groundwater Association","doi":"10.1111/j.1745-6584.1974.tb03033.x","usgsCitation":"Hughes, J.L., Eccles, L.A., and Malcolm, R.L., 1974, Dissolved organic carbon (DOC), an index of organic contamination in ground water near Barstow, California: Groundwater, v. 12, no. 5, p. 283-290, https://doi.org/10.1111/j.1745-6584.1974.tb03033.x.","productDescription":"8 p.","startPage":"283","endPage":"290","costCenters":[],"links":[{"id":419504,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"Barstow","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -117.1,\n              35\n            ],\n            [\n              -117.1,\n              34.75\n            ],\n            [\n              -116.75,\n              34.75\n            ],\n            [\n              -116.75,\n              35\n            ],\n            [\n              -117.1,\n              35\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"12","issue":"5","noUsgsAuthors":false,"publicationDate":"2006-07-06","publicationStatus":"PW","contributors":{"authors":[{"text":"Hughes, Jerry L.","contributorId":19944,"corporation":false,"usgs":true,"family":"Hughes","given":"Jerry","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":879459,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eccles, Lawrence A.","contributorId":90274,"corporation":false,"usgs":true,"family":"Eccles","given":"Lawrence","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":879460,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Malcolm, Ronald L.","contributorId":97500,"corporation":false,"usgs":true,"family":"Malcolm","given":"Ronald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":879461,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Surface-towed seismic reflection equipment was operated concurrently. The deep-tow data show that the slope is relatively smooth; this agrees with interpretation of surface seismic profiles. Features smaller than 1 km in length can be resolved with the deep profiles but not with the surface profiles. The deep profiles show smallscale undulations less than 0.5 km long that are especially well formed on the steeper parts of the slope. These undulations may be caused by minor downslope movement of surface sediment or by depositional processes. The deep-tow and surface seismic profiles can be combined to give a more accurate structural picture of the continental slope than can be obtained with surface data alone.</p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Silver, E.A., 1974, Detailed near-bottom geophysical profile across the continental slope off northern California: Journal of Research of the U.S. Geological Survey, v. 2, no. 5, p. 563-567.","productDescription":"5 p.","startPage":"563","endPage":"567","costCenters":[],"links":[{"id":402958,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":402957,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1974/vol2issue5/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -125.666,\n              41.666\n            ],\n            [\n              -124,\n              41.666\n            ],\n            [\n              -124,\n              42.25\n            ],\n            [\n              -125.666,\n              42.25\n            ],\n            [\n              -125.666,\n              41.666\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Silver, Eli A.","contributorId":83505,"corporation":false,"usgs":true,"family":"Silver","given":"Eli","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":845677,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
