The regional correlation ofthe geochemical records as well as interpretationsof these records on a global scale indicatethat changes in conodont biofacies of LateFamennian-Early Tournaisian limestones werecaused by a complex pattern of environmentalchanges.2008040043摩 洛 哥 东 北 部 石 炭 纪 Jerada 地 块 晚 维 宪 期 盆地 沉 积 层 序 中 微 生 物 海 绵 和 微 生 物 后 生 动 物岩 隆 = Microbial-sponge and microbialmetazoanbuildups in the Late Viséan basin-fillsequence of the Jerada Massif (Carboniferous,NE Morocco). ( 英 文 ). Aretz M; Herbig H G.Geological Journal, 2008, 43(2-3): 307 - 336Three distinctive Late Viséan buildup intervalsare differentiated on the southern limb ofthe Jerada Synclinorium. The oldest buildups(BI-1) are preserved as olistoliths in the Oued ElKoriche Formation (Fm). They were located ona southern platform prior to reworking. Theyounger Koudiat Es-Senn Fm contains twoautochthonous buildup intervals (BI-2 to BI-3).BI-1 and BI-2 buildups are large microbialspongebuildups, BI-3 are small microbialmetazoanbuildups in the capping bed successionabove BI-2. All buildups are characterized by arigid non-skeletal microbial framework. Growthof the largest BI-2 buildups started in aphotic todysphotic conditions in a water depth significantlyless than 100 m and continued into agitatedshallow-water. Smaller BI-2 buildups andall BI-3 buildups are encased in grainy shallowwatercarbonates. In contrast to a mostly homogeneousmicrobial-sponge facies below, the uppermostpart of the BI-2 buildups and all BI-3buildups consist of heterogeneous boundstoneswith differing frame builders. BI-1 to BI-3buildups represent different stages within aViséan basin-fill sequence. Carbonate sedimentationended with the deposition of peritidal oncoliticfloatstones below the unconformablyoverlying Namurian shales. The Jerada buildupshave many features commonly associated withreefs. Comparison with contemporaneous buildupsshows considerable similarities to buildupsfrom Algeria, the Eastern Moroccan Anti-Atlasand the British Isles.2008040044英 国 设 得 兰 群 岛 西 部 Foula 次 盆 地 坎 佩 尼 阶至 古 新 统 生 物 地 层 和 古 环 境 = Campanian toPalaeocene biostratigraphy and palaeoenvironmentsin the Foula Sub-basin, west of the ShetlandIslands, UK. ( 英 文 ). Van den Akker T J HA; Kaminski M A; Gradstein F M; Wood J.Journal of Micropalaeontology, 2000, 19(part 1):23-43For a detailed biostratigraphic framework ofthe Foula Sub-basin, located west of the ShetlandIslands (UK continental shelf), well 205/10-2B is chosen as a reference section. Based on thesuccession of last occurrence events of nominatetaxa, ten stratigraphically distinct Campanian toPalaeocene assemblages are described. The regionalapplicability of these events is tested bycorrelation between three wells in the Foula Subbasin(wells 205/10-2B, 206/3-1 and 206/5-1).Despite some local differences, the biostratigraphyof the Foula Sub-basin compares well withthe biostratigraphy of the Western Tethys andthe northern North Sea, and is therefore an importantlink between the southern and northernareas of the Northeast Atlantic margin. Amorphogroup analysis of agglutinating foraminiferain well 205/10-2B indicates depositionof Campanian and Maastrichtian mudstonesin a well oxygenated, lower bathyal environment,whereas Palaeocene sediments are deposited in amiddle to upper bathyal environment.微 体 古 生 物 学综 论2008040045意 大 利 南 亚 平 宁 山 脉 东 段 Faeto 和 Tufillo 组中 新 世 钙 质 浊 积 层 的 微 体 古 生 物 研 究 = Micropaleontologicalstudy on the Miocene calcareousturbidite deposits of Faeto and Tufilloformations (eastern sector of the Southern ApennineChain).

Rivista Italianadi Paleontologia e stratigrafia, 2007,113(2): Calcareous plankton biostratigraphy;Early and Middle Miocene; Mediterranean; factoFormation; TufilA biostratigraphic study was carried out onfour sections of the Miocene Tufillo and FaetoFormation. This study indicates that the lowerLanghian portion of the Tufillo Formation ischaracterized by arkose sandstones which passupwards into calcarenites and /or calciruditesand marly deposits. Field data suggest that thesesandstones directly overly the "Numidian Sandstones".The Faeto Formation starts with calcarenitesand calcareous marls, in the calcareousnannofossil MNN3b Zone (Burdigalian), andlies on the "Numidian Sandstones" as well.High-resolution dampling and biostratigraphyreveal that the deposition of the "NumidianSandstones" ends in the late Burdigalian stage,just below the FCO of S. heteromorphus(MNN3b) and the LO of C. dissimilis (MMi2bSubzone).200804004615
