( 英 文 ). Courtinat B.Journal of Micropalaeontology, 2000, 19(part 2):165-175Research carried out on the Upper Jurassicdinoflagellate cyst assemblages of the Sub-Tethyan marine realm, show that populations ofthe dinoflagellate cysts Subtilisphaera? inaffectaand S.? paeminosa are predominant in shallowwater marginal marine or brackish environments.The distribution of groups of dinoflagellate cysts,micrhystridid acritarchs and variations of terrestrialinputs represented by phytoclasts are presumedparameters of the salinity balance duringsuch Late Jurassic depositional environments. Inthis context, the shagreenate to faintly granulateS.? inaffecta appears to be an opportunistictaxon with an ability to prosper in brackish environments.In contrast, the coarsely granulate topustulate paeminosa form is seemingly less eurytopicand flourishes with success in shallow,marginal marine, environments. SEM studiesreveals that the two morphotypes possesstransapical archaeopyle sutures on what is usuallyconsidered the antapex. Following theseobservations the cysts are interpreted in a reversesense. Consequently, the attribution to the genusSubtilisphaera becomes inappropriate. The twomorphotypes, interpreted as variants of a singlespecies, are attributed to the genus CorculodiniumBatten & Lister, 1988 for which a newemendation is proposed. The specific epithetinaffecta is considered legal over paeminosa.2008040107大 西 洋 东 北 Goban Spur 大 陆 边 缘 沉 积 物 表面 的 硅 藻 流 = Diatom fluxes in surface sedimentsof the Goban Spur continental margin, NEAtlantic Ocean. ( 英 文 ). Bao R; De Stigter H;Van Weering T C E. Journal of Micropalaeontology,2000, 19(part 2): 123-131Continental slopes are presumed key areas fordeposition of organic carbon exported from theshelf. Analysis of across-slope differences indiatom and silicoflagellate fluxes recorded inbottom sediments of the Goban Spur margin, atypical North Atlantic slope environment, wascarried out to test if they can provide informationon the magnitude of advection of materialfrom the shelf into deeper waters. Total diatomand silicoflagellate accumulation rates showedstrong across-slope differences. Minimum valuesare recorded at the shelf break where maximumsurface productivity conditions occur while thedeeper sampling stations record fluxes as high as183x10(6) valves cm(-2) ka(-1). While high diatomfluxes show a clear correspondence with theactivity of a permanent bottom nepheloid layeroperating in the region, they do not correlatewith productivity patterns observed in the watercolumn. Diatom assemblages are mainly composedof Chaetoceros resting spores and Thalassionemanitzschioides (Grunow) Grunow exHustedt, typical indicators of spring bloom conditionsin the area. The absence of clear acrossslopetrends in the diatom assemblages is interpretedas the effect of random mixing driven bythe strong hydrodynamic regime provoked bythe activity of the bottom nepheloid layer. Thedominance of Chaetoceros resting spores acrossthe slope is related to important exportation ofshelf-derived production. However, due to thebroad ecological tolerances of the main taxacomposing the diatom assemblages, they do notallow precise estimations on the magnitude ofthe primary vertical flux vs, the secondary lateralflux in this slope environment. Use of thetychoplanktonic and benthic diatoms, which arerestricted to the neritic realm, allows only theestimation of the minimum amount of shelfderiveddiatoms reaching the slope sediments (atleast 13% of the total diatom assemblage for theupper slope area of the Goban Spur). This studyshows that major limitations exist for the use ofdiatoms preserved in surface sediments of thisarea as tracers of shelf-derived production transportedto the continental slope.2008040108Hallembaye 和 Turnhout ( 比 利 时 ) 和Beutenaken( 荷 兰 )Campanian-Danian 白垩 中 沟 鞭 藻 囊 胞 新 种 = New species ofdinoflagellate cysts from the Campanian-Danianchalks at Hallembaye and Turnhout (Belgium)and at Beutenaken (the Netherlands).
