Several of these possibilities are discussed in terms of the rock cycle. The mineralogy of clays neoformed in the weathering environment is a function of solution chemistry, with the most dilute solutions favoring formation of the least soluble clays. After erosion and transportation, these clays may be deposited on the ocean floor in a lateral sequence that depends on floccule size. Clays undergo little reaction in the ocean, except for ion exchange and the neoformation of smectite; therefore, most clays found on the ocean floor are inherited from adjacent continents. Upon burial and heating, however, dioctahedral smectite reacts in the diagenetic environment to yield mixed-layer illite-smectite, and finally illite. With uplift and weathering, the cycle begins again.

Group I leads have oceanic (mantle) characteristics, whereas group II leads have incorporated a continental-crustal component of at least early Proterozoic age. The group I leads are found in rocks from the Red Sea Hills of Egypt and the western and southern parts of the Arabian Shield. Group II leads are found in rocks from the northeastern and eastern parts of the Arabian Shield, as well as from the southeastern Shield near Najran. They are also found in rocks to the south in Yemen, to the east in Oman, and to the west at Aswan, Egypt. This distribution of data suggests that the Arabian-Nubian Shield has an oceanic core flanked by rocks that have developed, at least in part, from older continental material. Two mechanisms are suggested by which this older lead component could have been incorporated into the late Proterozoic rocks, and each may have operated in different parts of the Shield. The older lead component either was derived directly from an underlying early Proterozoic basement or was incorporated from subducted pelagic sediments or sediments derived from an adjacent continent. New U-Pb zircon data indicate the presence of an early Proterozoic basement southeast of Jabal Dahul in the eastern Arabian Shield. These data, together with 2,000-Ma-old zircons from the Al Amar fault zone, verify the implication of the common lead data that at least a part of the eastern Arabian Shield has an older continental basement. Because continental margins are particularly favorable locations for development of ore deposits, these findings may have important economic implications, particularly for tin, tungsten, and molybdenum exploration. ?? 1983 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01132334","issn":"00107999","usgsCitation":"Stacey, J.S., and Stoeser, D.B., 1983, Distribution of oceanic and continental leads in the Arabian-Nubian Shield: Contributions to Mineralogy and Petrology, v. 84, no. 1, p. 91-105, https://doi.org/10.1007/BF01132334.","startPage":"91","endPage":"105","numberOfPages":"15","costCenters":[],"links":[{"id":205061,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01132334"},{"id":220760,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"84","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a02ebe4b0c8380cd5026b","contributors":{"authors":[{"text":"Stacey, J.

The composition of the mixture was based on the differences between the amino acid contents of corn gluten meal and trout eggs. Fry fed the basal diet without added essential amino acids gained little weight, suffered high mortality and had eroded caudal fins. Addition of the mixture of amino acids (lysine, arginine, histidine, isoleucine, threonine, valine and tryptophan) significantly improved weight gain and prevented nearly all mortality and fin erosion. Single deletions of the amino acids valine, tryptophan, threonine, histidine and isoleucine had no significant effect on weight gain but the deletion of lysine alone significantly reduced weight gain and caused fin erosion and mortality. Deletion of arginine reduced weight gain (P&lt;.05), but did not cause mortality or fin erosion. Feeding graded levels of each of these two amino acids showed that the minimum lysine requirement for maximum growth was about 6.1% of protein, and the minimum arginine requirement was between 5.4 and 5.9% of protein.

Late Tertiary to early Pleistocene rivers eroded the pre-Mesozoic bedrock and the Upper Cretaceous to lower Tertiary coastal plain and continental shelf strata to form a lowland and cuesta having a north-facing escarpment. The lowland and landward flanks of the cuesta were modified by glaciers during Pleistocene time and subsequently were overlain by drift and end moraine deposits of the late Wisconsinan ice advance. During deglaciation, freshwater lakes formed between the retreating ice and end moraines. Prior to sea-level rise, the drift and older deposits were cut by streams flowing south and southwestward toward Block Island Sound. As sea level rose, postglacial valleys were partly filled by fluvial, freshwater-peat, estuarine and salt-marsh deposits. Transgressing seas eroded the sea floor, exposing bedrock and coastal plain outcrops, and deposited marine sediments. ?? 1983.","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(83)90033-6","issn":"00253227","usgsCitation":"Needell, S., O’Hara, C.J., and Knebel, H., 1983, Quaternary geology of the Rhode Island inner shelf: Marine Geology, v. 53, no. 1-2, p. 41-53, https://doi.org/10.1016/0025-3227(83)90033-6.","productDescription":"13 p.","startPage":"41","endPage":"53","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":221574,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Rhode Island","otherGeospatial":"Narragansett Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.51275634765625,\n              41.410805789669816\n            ],\n            [\n              -71.11450195312499,\n              41.410805789669816\n            ],\n            [\n              -71.11450195312499,\n              41.84808170729204\n            ],\n            [\n              -71.51275634765625,\n              41.84808170729204\n            ],\n            [\n              -71.51275634765625,\n              41.410805789669816\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"53","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a92c9e4b0c8380cd80a4b","contributors":{"authors":[{"text":"Needell, S.

Consideration of expected behavior of the regression solutions and results of a hypothetical modeling problem lead to several general conclusions. First, if the parameters are properly scaled, linearized expressions for the mean square error (MSE) in parameter estimates of a nonlinear model will often behave very nearly as if the model were linear. Second, by using prior information, the MSE in properly scaled parameters can be reduced greatly over the MSE of ordinary least squares estimates of parameters. Third, plots of estimated MSE and the estimated standard deviation of MSE versus an auxiliary parameter (the ridge parameter) specifying the degree of influence of the prior information on regression results can help determine the potential for improvement of parameter estimates. Fourth, proposed criteria can be used to make appropriate choices for the ridge parameter and another parameter expressing degree of overall bias in the prior information. Results of a case study of Truckee Meadows, Reno-Sparks area, Washoe County, Nevada, conform closely to the results of the hypothetical problem. In the Truckee Meadows case, incorporation of prior information did not greatly change the parameter estimates from those obtained by ordinary least squares. However, the analysis showed that both sets of estimates are more reliable than suggested by the standard errors from ordinary least squares.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR019i003p00662","usgsCitation":"Cooley, R.L., 1983, Incorporation of prior information on parameters into nonlinear regression groundwater flow models: 2.

Three long cores from the eastern and northern sides of the Aleutian Basin show changes in species assemblage which can be interpreted in terms of changes in the ocean environment during the last glaciation (Wisconsin) and the Holocene. The early and late Wisconsin maxima were times of prolonged annual sea-ice cover and a short cool period of phytoplankton productivity during the ice-free season. The middle Wisconsin interstade, at least in the southern Bering Sea, had greater seasonal contrast than today, with some winter sea-ice cover, an intensified temperature minimum, and high spring productivity. Variations in clastic and reworked fossil material imply varying degrees of transport to the basin by Alaskan rivers. The results of Jouse?? from the central Bering Sea generally correspond with those presented here, although there are problems with direct comparison. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(83)90079-0","issn":"00335894","usgsCitation":"Sancetta, C., and Robinson, S., 1983, Diatom evidence on Wisconsin and Holocene events in the Bering Sea: Quaternary Research, v. 20, no. 2, p. 232-245, https://doi.org/10.1016/0033-5894(83)90079-0.","startPage":"232","endPage":"245","numberOfPages":"14","costCenters":[],"links":[{"id":266557,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90079-0"},{"id":221277,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a00abe4b0c8380cd4f859","contributors":{"authors":[{"text":"Sancetta, C.","contributorId":14951,"corporation":false,"usgs":true,"family":"Sancetta","given":"C.","affiliations":[],"preferred":false,"id":360466,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Robinson, S.W.","contributorId":30985,"corporation":false,"usgs":true,"family":"Robinson","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":360467,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Comparison of HfNdSr c relationships for Tristan da Cunha, Kerguelen and Samoa reveals divergences in the mantle array for ocean island magma sources, and perhaps suggests that these irregularities are largely the result of an extra component of 87Sr/86Sr variation. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"LITHOS","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0024-4937(83)90033-6","issn":"00244937","usgsCitation":"Jonathan, P.P., 1983, Hafnium isotope results from mid-ocean ridges and Kerguelen: LITHOS, v. 16, no. 1, p. 47-51, https://doi.org/10.1016/0024-4937(83)90033-6.","startPage":"47","endPage":"51","numberOfPages":"5","costCenters":[],"links":[{"id":267967,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0024-4937(83)90033-6"},{"id":219683,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f53e4b0c8380cd5ccba","contributors":{"authors":[{"text":"Jonathan, Patchett P.","contributorId":85323,"corporation":false,"usgs":true,"family":"Jonathan","given":"Patchett","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":358753,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Significant mechanical compaction resulted from pressures simulating less than 1,000 ft of burial. Increasing loads to more than 10,000 ft did not significantly increase compaction. Chemical compaction was detected only in cores compacted to pressures greater than 10,000 ft of burial. These experiments suggest that chemical compaction would begin at much shallower depths given geologic time. Experiments that caused chemical compaction lend support to the hypothesis that cement required to produce a low-porosity/low-permeability fine-grained limestone is derived internally. Dissolution, ion diffusion, and reprecipitation are the most likely processes for creating significant thicknesses of dense limestones. Continuation of chemical compaction after significant porosity reduction necessitates expulsion of connate fluids, possibly including hydrocarbons.--Modified journal abstract.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F8242-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Shinn, E., and Robbin, D., 1983, Mechanical and chemical compaction in fine-grained shallow-water limestones: Journal of Sedimentary Petrology, v. 53, no. 2, p. 595-618, https://doi.org/10.1306/212F8242-2B24-11D7-8648000102C1865D.","productDescription":"24 p.","startPage":"595","endPage":"618","numberOfPages":"24","costCenters":[],"links":[{"id":220695,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"53","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5357e4b0c8380cd6c9f7","contributors":{"authors":[{"text":"Shinn, E.A.","contributorId":38610,"corporation":false,"usgs":true,"family":"Shinn","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":360677,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Robbin, D.M.","contributorId":101384,"corporation":false,"usgs":true,"family":"Robbin","given":"D.M.","affiliations":[],"preferred":false,"id":360678,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
