Mean total DDT concentrations declined from 19.19 mg/kg in 1970 to 2.74 mg/kg in 1982. The decline in both contaminants closely followed first order loss kinetics. If the current decline continues, PCB concentrations will decline to the USFDA tolerance of 2.0 mg/kg in 1988. Mean total DDT concentrations will fall to the IJC objective of 1.0 mg/kg by 1991. Mean dieldrin concentrations increased significantly from 0.20 mg/kg in 1971 to 0.58 mg/kg in 1979 before declining to 0.21 mg/kg in 1982. The decline from 1979-1982 followed first order loss kinetics. As this decline is not reflected in other species (bloater chubs, smelt) it will require additional years of monitoring to determine if the decline in dieldrin concentrations between 1979 and 1982 truly represents a declining trend.\rContaminants in lake trout from Lake Superior and Lake Huron generally declined over the study period. The only statistically significant trend other than in Lake Michigan was for total DDT which declined significantly in Lake Superior lake trout. Large data variance and the short time frame covered (1977-1982) interfered with detection of trends on Lakes Superior and Huron.","language":"English","usgsCitation":"DeVault, D.S., Willford, W.A., and Hesselberg, R.J., 1985, Contaminant trends in lake trout (Salvelinus namaycush) of the upper Great Lakes, 22 p.","productDescription":"22 p.","startPage":"22","numberOfPages":"22","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":127974,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cfe4b07f02db546366","contributors":{"authors":[{"text":"DeVault, David S.","contributorId":22720,"corporation":false,"usgs":true,"family":"DeVault","given":"David","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":297811,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Willford, Wayne A.","contributorId":67446,"corporation":false,"usgs":true,"family":"Willford","given":"Wayne","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":297813,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hesselberg, Robert J.","contributorId":36074,"corporation":false,"usgs":true,"family":"Hesselberg","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":297812,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

X-ray fluorescence (XRF) spectroscopy has come to play a vital role in this environment largely because it is a dependable, multielement, rapid method that covers a wide range of elemental concentrations, commonly with only one sample preparation. The following discussion centers on the role of modern XRF instrumentation in the resolution of geochemical problems.

Santa Rosa Lake has caused changes in the ground water flow system, which may cause changes in the streamflow of the Pecos River that cannot be detected at the present streamflow-gaging stations, which are used to administer water rights along the Pecos River. The effect of the lake on streamflow was investigated using a three-dimensional ground water flow model.

Detachment sliding could have occurred around the volcano if either pore-fluid pressures were exceptionally high (greater than 90%) or the rocks had very low resistance to shear (about 1 × 10</span><sup>5</sup><span>&nbsp;Pa or 1 bar). Because of the vast areal extent and probable shallow depth of the detachment zone, development of ubiquitous, high pore-fluid pressures beneath aureole-forming material was unlikely. However, a zone of sufficiently weak material consisting of about 10% interstitial or interbedded ice could have been present. If so, a simple rheologic model for the aureole deposits can be applied that consists of a thin ductile layer overlain by a thicker brittle layer. According to this model, extensional deformation would have occurred near the shield and compressional deformation in its distal parts. Proximal grabens and distal corrugations on aureole surfaces support this model. A submarine slide at Kitimat Arm, British Columbia, is a valid qualitative analogy for the observed features and inferred emplacement style of the aureole deposits. Ground-ice processes have been considered the cause of many geologic features on Mars; a 3% average concentration of ground ice in the regolith is predicted by theoretical models for the ice budget and cryosphere. Ice may have been deposited in higher concentrations below the aureole-forming material; the source of the ice could have been juvenile water circulated hydrothermally by Olympus Mons volcanism. The basal scarp of Olympus Mons apparently demarcates the transition between the upper, stable part of the shield and its lower part that decoupled and formed the aureole deposits. This transition may reflect a change in the bulk shear strength of the shield, caused either by a radial dependence in the abundance of ice or fluid in the shield materials or by the concentration of intrusive dikes within the volcano. Other Martian volcanoes exhibit virtually no evidence of similar large-scale gravity spreading and basal scarps. Perhaps such evidence, if it existed, has been buried by lava flows, or perhaps the smaller size of other volcanoes did not permit the development of these features.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0019-1035(85)90117-4","issn":"00191035","usgsCitation":"Tanaka, K.L., 1985, Ice-lubricated gravity spreading of the Olympus Mons aureole deposits: Icarus, v. 62, no. 2, p. 191-206, https://doi.org/10.1016/0019-1035(85)90117-4.","productDescription":"16 p.","startPage":"191","endPage":"206","numberOfPages":"16","costCenters":[],"links":[{"id":221966,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"62","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a37fae4b0c8380cd61324","contributors":{"authors":[{"text":"Tanaka, K.

It was probably reactivated during early Mesozoic continental breakup and again in the Late Cretaceous and Tertiary, causing the steeply dipping postrift New Shoreham fault to form, either as an antithetic (normal) or splay (reverse) fault.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1985)13<875:BIFAPC>2.0.CO;2","usgsCitation":"Hutchinson, D.R., Klitgord, K.D., and Detrick, R.S., 1985, Block Island fault: A Paleozoic crustal boundary on the Long Island platform: Geology, v. 13, no. 12, p. 875-879, https://doi.org/10.1130/0091-7613(1985)13<875:BIFAPC>2.0.CO;2.","productDescription":"5 p.","startPage":"875","endPage":"879","onlineOnly":"N","additionalOnlineFiles":"N","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":296776,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Long Island platform","volume":"13","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5492b73ce4b00eda8915ad07","contributors":{"authors":[{"text":"Hutchinson, Deborah R. 0000-0002-2544-5466 dhutchinson@usgs.gov","orcid":"https://orcid.org/0000-0002-2544-5466","contributorId":521,"corporation":false,"usgs":true,"family":"Hutchinson","given":"Deborah","email":"dhutchinson@usgs.gov","middleInitial":"R.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":536915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klitgord, Kim D.","contributorId":82307,"corporation":false,"usgs":true,"family":"Klitgord","given":"Kim","email":"","middleInitial":"D.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":536916,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Detrick, R.

This limestone accumulated during an interglacial high stand of sea level about 200,000 years ago. Dolomitization was preceded by freshwater diagenesis, including precipitation of sparry calcite cement, stabilization of Mg-calcitic skeletal fragments, and partial dissolution of aragonitic components. This suggests a predolomitization lowering of sea level with the consequent freshening of pore water. The subsequent precipitation of dolomite indicates a return to high sea level with the consequent increase in Mg/Ca ratio of pore water. Dolomitization took place during a brief high stand of sea level, either shortly after deposition about 200,000 yr BP, or, more likely, about 125,000 yr BP. Dolomite occurs both as microcrystalline replacement dolomite and as cement. The cement is part of the following diagenetic sequence: 1) limpid euhedral-subhedral calcian dolomite crystals, 2) zoned dolomite crystals with zones formed by variations of the calcium/magnesium ratio in dolomite, 3) layers of alternating calcian dolomite and magnesian calcite or calcite, and 4) calcite. This sequence represents the progressive freshening of ground water during the initial stage of a fall in sea level. Average cation composition of the limpid dolomite cement is Ca<span>&nbsp;</span><sub>57</sub><span>&nbsp;</span>Mg<span>&nbsp;</span><sub>43</sub><span>&nbsp;</span>(electron microprobe analysis). Zoned cement crystals are composed of Ca (sub 57-59) Mg (sub 43-41) layers and Ca<span>&nbsp;</span><sub>62</sub><span>&nbsp;</span>Mg<span>&nbsp;</span><sub>38</sub><span>&nbsp;</span>layers. Most of the higher-calcium dolomite layers are dissolved, forming hollow-zone crystals. In cement with alternating dolomite and calcite zones, the calcite is Ca (sub 99-97) Mg (sub 1-3) (low-Mg calcite) and Ca (sub 96-93) Mg (sub 4-7) (Mg calcite). The dolomite and Mg calcite zones are partially to totally leached. delta<span>&nbsp;</span><sup>18</sup><span>&nbsp;</span>O compositions of Yucatecan dolomite and of modern ground water suggest dolomite precipitation from mixed water ranging from about 75% seawater, 25% freshwater to nearly all seawater. (Isotope analyses are for the most stable calcian dolomites; more soluble, calcium-rich dolomite presumably is analyzed with calcite and thought to be isotopically lighter than the less soluble dolomite.) In the cement sequence, the most stable dolomite is followed by more soluble dolomite as ground water becomes less saline. Isotope analyses, together with position of dolomite in the cement sequence, suggest the most stable calcian dolomite (including limpid dolomite) precipitated from mixed water with large proportions of seawater, and the less stable, more calcian dolomite precipitated from fresher mixed water.</p></div></div>","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.1306/212F86E8-2B24-11D7-8648000102C1865D","usgsCitation":"Ward, W.C., and Halley, R., 1985, Dolomitization in a mixing zone of near-seawater composition, Late Pleistocene, northeastern Yucatan Peninsula: Journal of Sedimentary Research, v. 55, no. 3, p. 407-420, https://doi.org/10.1306/212F86E8-2B24-11D7-8648000102C1865D.","productDescription":"14 p.","startPage":"407","endPage":"420","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":296753,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/sepm/journals/v55-58/data/055/055003/0407.htm"},{"id":296754,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico","otherGeospatial":"Yucatan Peninsula","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.07666015625,\n              17.853290114098012\n            ],\n            [\n              -92.13134765625,\n              18.89589255941504\n            ],\n            [\n              -90.3955078125,\n              21.248422235627014\n            ],\n            [\n              -86.6162109375,\n              21.881889807629282\n            ],\n            [\n              -87.73681640625,\n              18.166730410221938\n            ],\n            [\n              -88.35205078124999,\n              18.687878686034196\n            ],\n            [\n              -89.40673828125,\n              17.874203439657514\n            ],\n            [\n              -91.07666015625,\n              17.853290114098012\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"55","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5492b73ee4b00eda8915ad0e","contributors":{"authors":[{"text":"Ward, W.

Whether these structures control the location of, or movement on, the fault is not clear.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1985)96<975:NYBF>2.0.CO;2","usgsCitation":"Hutchinson, D.R., and Grow, J., 1985, New York Bight fault: Geological Society of America Bulletin, v. 96, no. 8, p. 975-989, https://doi.org/10.1130/0016-7606(1985)96<975:NYBF>2.0.CO;2.","productDescription":"15 p.","startPage":"975","endPage":"989","onlineOnly":"N","additionalOnlineFiles":"N","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":296777,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New Jersey, New York","otherGeospatial":"New York Bight","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.739990234375,\n              39.97291055131899\n            ],\n            [\n              -73.0535888671875,\n              39.97291055131899\n            ],\n            [\n              -73.0535888671875,\n              41.18692242290296\n            ],\n            [\n              -74.739990234375,\n              41.18692242290296\n            ],\n            [\n              -74.739990234375,\n              39.97291055131899\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"96","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5492b746e4b00eda8915ad2a","contributors":{"authors":[{"text":"Hutchinson, Deborah R. 0000-0002-2544-5466 dhutchinson@usgs.gov","orcid":"https://orcid.org/0000-0002-2544-5466","contributorId":521,"corporation":false,"usgs":true,"family":"Hutchinson","given":"Deborah","email":"dhutchinson@usgs.gov","middleInitial":"R.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":536918,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grow, John A.","contributorId":51739,"corporation":false,"usgs":true,"family":"Grow","given":"John A.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":536919,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
