( 英 文 ). Halfar J; Ingle J C. Journal ofForaminiferal Research, 2003, 33(4): 309-329 3图 版 .The La Paz area of the southwestern Gulf ofCalifornia, Mexico, provides an ideal setting forstudying the distribution of Recent warmtemperateto subtropical littoral to inner neriticforaminiferal assemblages in a carbonatedominatedsetting. Four representative subenvironmentsincluding two pocket bays, a rhodolithdominatedcarbonate bioherm, and a mixed carbonate-siliciclastichigh-energy beach were selectedfor detailed foraminiferal analysis. Assemblagesof benthic foraminifera were comparedto bottom observations, time-series temperaturerecordings, and occurrences of othercarbonate-producing biota. Foraminifera are ofintermediate importance among carbonate producersin the La Paz environments, making up4% of the total calcareous biota. However, theyreach abundances of up to 27% in middle shelflocalities where species numbers are also highest.Miliolid foraminifera, dominated by the genusQuinqueloculina, are the most abundant groupand frequently comprise more than 60% of foraminiferalassemblages. Larger foraminiferainclude Peneroplis pertusus pertusus, P. pertususarietina, Amphisorus hemprichii, Gypsinavesicularis, and Sphaerogypsina globulus. Thedistribution of shallow-water assemblages in theLa Paz environments is largely controlled bysubstrate type. Q- and R-mode cluster analysesrevealed eight distinct foraminiferal biofaciesthat appear to be related to microlithofacies definedon the basis of biogenic components. Assemblagesinclude mixtures of tropical and temperatespecies as demonstrated by the abundanceof Peneroplis pertusus, Amphisorus hemprichii,and Quinqueloculina spp., which are representativeof tropical communities. In contrast, themost abundant species with temperate affinitiesinclude Buccella parkerae, Gavelinopsis sp.,Haplophragmoides sp., and Oolina melo. Applicationof the Murray model for distinguishingcool-temperate, warm-temperate, and subtropicalfaunas clearly points to the warm-temperate tosubtropical character of the foraminiferal assemblagesassociated with the carbonate factoriesand environments of the southern Gulf of California.2008040189大 洋 南 部 记 录 中 特 提 斯 洋 晚 白 垩 世 的 浮 游 有孔 虫 生 物 事 件 - 综 述 = Late Cretaceous planktonicforaminiferal bioevents in thetethys and inthe southern Ocean record: an overview. ( 英 文 ).Petrizzo M R. Journal of Foraminiferal Research,2003, 33(4): 330-337 1 图 版 .The Late Cretaceous planktonic foraminiferaldistribution recorded at several drill sites (DeepSea Drilling Project and Ocean Drilling Program)in the South Atlantic and south Indian Oceanand from sediment outcrops in the Tethyan region(Gubbio and El Kef) have been analyzed inorder to investigate the presence of a similar sequenceof bioevents occurring at low, middle,and high latitude. Comparative analysis highlightsthe co-occurrence of several bioevents;some of them are isochronous bioevents occurringin the Tethys and in the Southern Oceanrecord, whereas others are diachronous acrosslatitudes but can be used for correlation at regionalscale, as they show the same stratigraphicdistribution in the South Atlantic and IndianOcean record. Isochronous bioevents are the firstand the last occurrence of Helvetoglobotruncanahelvetica, and the first appearance of Falsotruncanamaslakovae in the lower-middle Turonian.The first occurrence of Heterohelix papula in theSouthern Ocean sites, correlated with the firstoccurrence of large heterohelicids in the Tethyanarea, allows the Coniacian/Santonian boundaryto be identified. The most reliable bioevents usefulfor correlation at a regional scale in theSouthern Ocean record are the last occurrence ofthe marginotruncanids in the upper Santonian,the first and the last occurrence of Globigerinelloidesimpensus from the uppermost Santonianto upper Campanian, the first occurrence of Heterohelixrajagopalani in the middle-upper Campanian,and the appearance of Abathomphalusmayaroensis in the lower Maastrichtian.2008040190土 耳 其 南 部 Taurides 中 部 Aydincik 地 区 下 侏罗 统 碳 酸 盐 的 生 物 地 层 学 和 Lituolipora termieri(hottinger, 1967) 的 形 态 分 析 = Biostratigraphyof the Lower Jurassic carbonates fromthe aydincik area (central taurides, S.
