Sediment slides of widely varying size and shape are common in Quaternary deposits of the upper slope, particularly where gradients are steep. Our study of a large sediment failure in lowstand prograded coastal deposits west of Cape Licosa indicates that the nature of shelf-margin deposition is an additional important control on failure.</p><p id=\"SP0010\">The failure zone has a mobilization surface showing in-situ deformation in the sediment above it; an upper failure surface; a head scarp; and a zone of ponded sediment debris downslope from the exposed surface of failure. The basal mobilization surface is roughly parallel to the seafloor and coincident with a major downlap surface. The failed section is less that 20 m thick and local in extent, but deformation on the basal mobilization surface extends outside the immediate area of the failure. Directly downslope of the slide scarp are internally stratified mounds that show no evidence of deformation or movement. Most of the prograded deposit experienced in-situ deformation that evolved into the collapse of part of the sediment pile above the mobilization surface. A portion of the mobilized sediment flowed a few kilometers basinward and accumulated at the base of a slope-parallel ridge.</p><p id=\"SP0015\">Sediment failure occurred on the Licosa shelf margin following a major pulse of coastal sedimentation along the lowstand shoreline. On many continental margins, sea-level lowering is thought to be an important cause of failure unconsolidated sediment deposited during previous high-stand conditions. The Licosa slide demonstrates that sea-level fall has another, equally important but indirect, role in sediment failure. As sea level falls and reaches its lowstand position, streams are at their peak efficiency and a coarsening-upward clastic coastal wedge is rapidly emplaced at relatively steep gradients on the shelf margin, and these are conditions that inherently favor sediment instability and failure.</p></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(92)90183-I","issn":"00253227","usgsCitation":"Trincardi, F., and Field, M., 1992, Collapse and flow of lowstand shelf-margin deposits: An example from the eastern Tyrrhenian Sea, Italy: Marine Geology, v. 105, no. 1-4, p. 77-94, https://doi.org/10.1016/0025-3227(92)90183-I.","productDescription":"18 p.","startPage":"77","endPage":"94","numberOfPages":"18","costCenters":[],"links":[{"id":224738,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"105","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f7ace4b0c8380cd4cc44","contributors":{"authors":[{"text":"Trincardi, F.","contributorId":94794,"corporation":false,"usgs":true,"family":"Trincardi","given":"F.","affiliations":[],"preferred":false,"id":376150,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Field, M.E.","contributorId":27052,"corporation":false,"usgs":true,"family":"Field","given":"M.E.","affiliations":[],"preferred":false,"id":376149,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Currently, one of the largest costs in applying spatial data analysis is the cost of developing the needed spatial data. Therefore, guidelines and standards are required for the development of spatial data in order to allow for data sharing and reuse; this eliminates costly redevelopment. In order to attain this goal, the USGS is expanding efforts to identify guidelines and standards for the development of spatial data for hydrologic analysis. Because of the variety of project and database needs, the USGS has concentrated on developing standards for documenting spatial sets to aid in the assessment of data set quality and compatibility of different data sets. An interim data set documentation standard (1990) has been developed that provides a mechanism for associating a wide variety of information with a data set, including data about source material, data automation and editing procedures used, projection parameters, data statistics, descriptions of features and feature attributes, information on organizational contacts lists of operations performed on the data, and free-form comments and notes about the data, made at various times in the evolution of the data set. The interim data set documentation standard has been automated using a commercial geographic information system (GIS) and data set documentation software developed by the USGS. Where possible, USGS developed software is used to enter data into the data set documentation file automatically. The GIS software closely associates a data set with its data set documentation file; the documentation file is retained with the data set whenever it is modified, copied, or transferred to another computer system. The Water Resources Division of the USGS is continuing to develop spatial data and data processing standards, with emphasis on standards needed to support hydrologic analysis, hydrologic data processing, and publication of hydrologic thermatic maps. There is a need for the GIS vendor community to develop data set documentation tools similar to those developed by the USGS, or to incorporate USGS developed tools in their software.","largerWorkTitle":"ASTM Special Technical Publication","conferenceTitle":"International Symposium on Mapping and Geographic Information Systems","conferenceDate":"21 June 1990 through 22 June 1990","conferenceLocation":"San Francisco, CA, USA","language":"English","publisher":"Publ by ASTM","publisherLocation":"Philadelphia, PA, United States","issn":"10403094","usgsCitation":"Fulton, J.L., 1992, Development of spatial data guidelines and standards: spatial data set documentation to support hydrologic analysis in the U.S. Geological Survey, <i>in</i> ASTM Special Technical Publication, no. 1126, San Francisco, CA, USA, 21 June 1990 through 22 June 1990, p. 30-37.","startPage":"30","endPage":"37","numberOfPages":"8","costCenters":[],"links":[{"id":223416,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"1126","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0064e4b0c8380cd4f739","contributors":{"authors":[{"text":"Fulton, James L.","contributorId":103798,"corporation":false,"usgs":true,"family":"Fulton","given":"James","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":373161,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Emergence probably would have prevailed at a fourth site near Maulli??n were the site not underlain by easily compacted deposits; this site shows slight (< 1 m) net submergence in the past 3000 years. Despite net emergence, all four sites underwent 1-2 m of submergence from tectonic subsidence during a magnitude-9.5 earthquake in 1960, and two of the sites show evidence for earlier submergence events of Late Holocene age. The net emergence is probably due to some combination of cyclic uplift from elastic strain accumulation between earthquakes and monotonic uplift from postglacial loading of the Pacific Ocean floor. The small amount of the net emergence shows that neotectonics has had little net impact on Holocene relative sea level in part of the focal region of the largest earthquake recorded by seismograph. ?? 1992.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/1040-6182(92)90037-3","issn":"10406182","usgsCitation":"Atwater, B., Nunez, H., and Vita-Finzi, C., 1992, Net Late Holocene emergence despite earthquake-induced submergence, south-central Chile: Quaternary International, v. 15-16, no.

Application of earth-science data in complex geographic information systems, acceleration of geologic map production, and reduction of population costs require that national standards be developed for digital geologic cartography and computer analysis. Since December 1988, under commission of the Chief Geologic of the U.S. Geological Survey and the mandate of the National Geologic Mapping Program (with added representation from the Association of American State Geologists), a committee has been designing a comprehensive set of scientific map standards. Three primary issues were: (1) selecting scientific symbology and its digital representation; (2) creating an appropriate digital coding system that characterizes geologic features with respect to their physical properties, stratigraphic and structural relations, spatial orientation, and interpreted mode of origin; and (3) developing mechanisms for reporting levels of certainty for descriptive as well as measured properties. Approximately 650 symbols for geoscience maps, including present usage of the U.S Geological Survey, state geological surveys, industry, and academia have been identified and tentatively adopted. A proposed coding system comprises four-character groupings of major and minor codes that can identify all attributes of a geologic feature. Such a coding system allows unique identification of as many as 105 geologic names and values on a given map. The new standard will track closely the latest developments of the Proposed Standard for Digital Cartographic Data soon to be submitted to the National Institute of Standards and Technology by the Federal Interagency Coordinating Committee on Digital Cartography. This standard will adhere generally to the accepted definitions and specifications for spatial data transfer. It will require separate specifications of digital cartographic quality relating to positional accuracy and ranges of measured and interpreted values such as geologic age and rock composition. Provisional digital geologic map standards will be published for trial implementation. After approximately two years, when comments on the proposed standards have been solicited and modifications made, formal adoption of the standards will be recommended. Widespread acceptance of the new standards will depend on their applicability to the broadest range of earth-science map products and their adaptability to changing cartographic technology.","largerWorkTitle":"ASTM Special Technical Publication","conferenceTitle":"International Symposium on Mapping and Geographic Information Systems","conferenceDate":"21 June 1990 through 22 June 1990","conferenceLocation":"San Francisco, CA, USA","language":"English","publisher":"Publ by ASTM","publisherLocation":"Philadelphia, PA, United States","issn":"10403094","usgsCitation":"Ulrech, G.E., Reynolds, M.W., and Taylor, R.B., 1992, Toward digital geologic map standards: a progress report, <i>in</i> ASTM Special Technical Publication, no. 1126, San Francisco, CA, USA, 21 June 1990 through 22 June 1990, p. 18-29.","startPage":"18","endPage":"29","numberOfPages":"12","costCenters":[],"links":[{"id":224757,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"1126","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb5b6e4b08c986b32684c","contributors":{"authors":[{"text":"Ulrech, George E.","contributorId":51471,"corporation":false,"usgs":true,"family":"Ulrech","given":"George","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":374702,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Mitchell W. 0000-0002-9966-3896 mwreynol@usgs.gov","orcid":"https://orcid.org/0000-0002-9966-3896","contributorId":4641,"corporation":false,"usgs":true,"family":"Reynolds","given":"Mitchell","email":"mwreynol@usgs.gov","middleInitial":"W.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":374700,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Taylor, Richard B.","contributorId":19539,"corporation":false,"usgs":true,"family":"Taylor","given":"Richard","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":374701,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These results provided information on the current geochemical evolution of ground waters for two study sites within the Po&ccedil;os de Caldas Natural Analogue Project.</p>\n<p id=\"para5\" class=\"svArticle section\">The ground waters are a K&ndash;Fe&ndash;SO<sub>4</sub>&ndash;F type, a highly unusual composition related to intense weathering of a hydrothermally altered and mineralized complex of phonolites. Tritium and stable isotope data indicate that ground waters are of meteoric origin and are not affected significantly by evaporation or water&ndash;rock interactions. Recharging ground waters at both study sites demonstrate water of less than about 35 years in age, whereas deeper, more evolved ground waters are below 1 TU but still contain in most cases detectable tritium. These deeper ground waters may be interpreted as being of 35 to 60 or more years in age, resulting mainly from an admixture of younger with older ground waters and/or indicating the influence of subsurface produced tritium.</p>\n<p id=\"para6\" class=\"svArticle section\">Geochemical processes involving water&ndash;rock&ndash;gas interactions have been modeled using ground water compositions, mineralogic data, ion plots and computations of speciation, non-thermodynamic mass balance and thermodynamic mass transfer. The geochemical reaction models can reproduce the water chemistry and mineral occurrences and they were validated by comparing the results of thermodynamic mass transfer calculations (using the PHREEQE program, Parkhurst et al., 1980). The results from the geochemical reaction models reveal that the dominant processes are production of CO<sub>2</sub> in the soil zone through aerobic decay of organic matter, dissolution of fluorite, calcite, K-feldspar, albite, chlorite and manganese oxides, oxidation of pyrite and sphalerite, and precipitation of ferric oxides, silica and kaolinite. Gibbsite precipitation can be modeled for the shallow (recharge) water chemistry at Morro do Ferro, consistent with known mineralogy. Recharge waters are undersaturated with respect to barite and discharging waters and deeper ground waters are saturated to supersaturated with respect to barite demonstrating a strong solubility control. Strontium isotope data demonstrate that sources other than calcium-bearing minerals are required to account for the dissolved strontium in the ground waters. These may include K-feldspar, smectite&ndash;chlorite mixed-layer clays and goyazite [SrAl<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> (OH)<sub>5</sub> &bull; H<sub>2</sub>O].</p>\n<p>&nbsp;1992.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/B978-0-444-89934-7.50011-6","issn":"03756742","usgsCitation":"Nordstrom, D.K., McNutt, R., Puigdomenech, I., Smellie, J.A., and Wolf, M., 1992, Ground water chemistry and geochemical modeling of water-rock interactions at the Osamu Utsumi mine and the Morro do Ferro analogue study sites, Poços de Caldas, Minas Gerais, Brazil: Journal of Geochemical Exploration, v. 45, no. 1-3, p. 249-287, https://doi.org/10.1016/B978-0-444-89934-7.50011-6.","productDescription":"39 p.","startPage":"249","endPage":"287","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":224677,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2aaae4b0c8380cd5b371","contributors":{"authors":[{"text":"Nordstrom, D.
