Saanich than exists today sedimentological andforaminiferal evidence indicate that bottom waterswere oxygenated. The foraminiferal faunaindicates that oxygen levels varied from a minimumlow oxic (1.5–3 ml/l [67–133 µM]) levelearly on to suboxic (0.3–1.5 ml/l [13.3–67 µM])conditions up section where sediments becomeprogressively more laminated. During the earlyHolocene air temperatures in the region were upto 4°C warmer, and it was much drier than atpresent. The resultant reduced freshwater flowinto the southern Strait of Georgia was conduciveto the free exchange of Saanich Inlet bottomwaters with those of well-oxygenated Haro Strait.After 7000 years BP the climate in the regioncooled and, as the influence of freshwater fromStrait of Georgia increased, oxygenation ofSaanich bottom waters became a rare occurrence.Finely-laminated sediments characterized mid-Holocene to Recent sediments in the inlet reflectingthe development of full anoxic conditionsat depth. The Lobatula fletcheri–Buccellafrigida Biofacies 1 characterizing this interval isallochthonous and derived by down-slope transportfrom shallower, more oxygenated regions ofSaanich Inlet.2008040202墨 西 哥 的 Lepidorbitoides minima Douville-坎 佩 尼 阶 有 孔 虫 的 标 志 化 石 = Lepidorbitoidesminima Duville from Mexico, a foraminiferalindex fossil for the Campanian.

Journalof Foraminiferal Research, 2002, 32(2): 126-134 8 图 版 .Mexican topotypes of Lepidorbitoides minimaDouvillé, type species of the genus OrbitocyclinaVaughan 1929, exhibit an orbitoidiform architectureconditioned by an obliquelyovercrossedstolon system in only three stolonplanes in the medium layer of the shell and arisingfrom a single auxiliary chamberlet. This architectureis identical with the one observed inCampanian early species of the Tethyan genusLepidorbitoides.Orbitocyclina is therefore placed in synonymywith Lepidorbitoides Silvestri, 1907. This opensthe way for a transatlantic biozonation based onquantitative methods supported by evolutionarytheory using nepionic acceleration as a measurablefeature.2008040203西 班 牙 Cantabrian 带 中 Gzhelian 早 期 的 蜓类 的 特 征 和 古 地 理 亲 缘 性 = Characteristicsand paleogeographic affinities of the early Ghelianfusulinoideans from the Cntabrian Zone(NW Spain). ( 英 文 ). Villa E; Ueno K. Journal ofForaminiferal Research, 2002, 32(2): 135-154 5图 版 .This paper deals with the fusulinoidean faunasfrom several recently found Gzhelian localitiesof the Cantabrian Zone (Spain). All localitieshave strata belonging to the Puentellés Formation,a lithostratigraphic unit exposed in thenorthern part of the Picos de Europa Massifs.Three Ferganites species, including F. obesus sp.nov., and several others belonging to the generaRauserites, Tumefactus, Triticites? and Quasifusulinaare described. The three Ferganites speciesbelong to a single species group, which is sofar only known from the Carboniferous of theCantabrian Zone. A comparison of these Cantabrianassemblages with contemporaneous faunasfrom other Carboniferous areas of westernEurasia shows that forms such as Rauserites cf.R. rossicus and Quasifusulina aff. Q. longissimaultima are either identical or closely related tospecies that were probably widespread in thepaleo-equatorial part of Eurasia. Other elements(e.g., Ferganites ex gr. F. obesus, Tumefactus exgr. Tu. expressus, Triticites? aff. Tr.? gusanicus)had a much more restricted geographic distributionand occurred only in the western part of thePaleo-Tethys. The assemblages are thus correlatedwith the lower Gzhelian of the RussianPlatform. The fusulinoidean faunas studieddemonstrate that the westernmost part of thePaleo-Tethys was still characterized by marinedeposits in Gzhelian times. Apparently, the CantabrianZone had close affinities with the CarnicAlps and Central Asia and, like these areas, itwas part of the Late Carboniferous (Pennsylvanian)Paleo-Tethyan province.2008040204阿 曼 东 部 Batain 平 原 中 二 叠 统 米 德 阶 的 有 孔虫 组 合 及 它 们 对 新 特 提 斯 洋 古 地 理 研 究 的 意义 = Middle Permian (Midian) foraminiferalassemblages from the Batain plain (EasternOman):their significance Neotethyan paleogeography.( 英 文 ). Vachard D; Hauser M; MartiniR; Zaninetti L; Matter A; Peters T. Journalof Foraminiferal Research, 2002, 32(2): 155-172 6 图 版 .Exceptionally rich Permian fusulinid assemblages,varying in age from Yakhtashian toDzhulfian, were found in reworked limestoneblocks from conglomerates of the Aseelah Unit,recently defined in the Batain Plain and datedpossibly as Upper Triassic. This paper only dealswith the Middle Permian, Midian (= Capitanian)microfaunas from the conglomerates. The AseelahUnit is found associated with the Triassic SalFormation, tectonically overlying the QarariUnit, and is dated as Middle to Late Permianbased on ammonoid assemblages and conodonts.64
