The phytoliths are comparable to modern tree/shrub, grass, and fern forms, although some may be modern contaminants. Spherical tree/shrub phytoliths are the most common, occurring particularly in the lower middle to middle Miocene core sections at Site 1165. All phytolith forms observed (except irregular and folded sphericals) have been previously described in other Antarctic sediments. The low phytolith abundances in the cores probably result from a combination of factors including the substantial distance offshore of the drill sites, taphonomic influences (low source production, soil dissolution, and dilution of terrigenous material during transport and deposition), and silica diagenesis downhole.completedStratigraphyAntarcticabiostratigraphyCenozoiccoresCretaceousdiagenesisEast AntarcticaLeg 188marine sedimentsMesozoicOcean Drilling ProgramODP Site 1165ODP Site 1166phytolithsPlantaePrydz BayQuaternarysedimentsSouthern OceanUpper Cretaceousurn:org.iodp:exp:188urnlargerWorkCitationcampaignurn:org.iodp:exp:188:site:1165urnlargerWorkCitationstudyurn:org.iodp:exp:188urnlargerWorkCitationcampaignurn:org.iodp:exp:188:site:1166urnlargerWorkCitationstudyurn:org.iodp:exp:188urnlargerWorkCitationcampaignEnglishgeoscientificInformation67.130074.4800-67.4200-64.2200Data report; available only on CD-ROM in PDF format and on the Web in PDF and HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/188_SR/VOLUME/CHAPTERS/002.PDFdownload
