floatstones with a matrix usually consisting ofbryozoan fragments, benthic foraminifera andechinoid fragments or terrigenous silty fine sand.The rhodoliths of type B units usually have aloose internal framework with irregular tobranched crusts. The two contrasting rhodolithbearingunits are interpreted as characteristicfacies of transgressive systems tract deposits,analogous to shell concentrations formed underconditions of low net sedimentation. Type Adeposits are correlated with relatively highenergysettings and/or narrow submerged palaeotopographiclows, whereas type B depositsare interpreted as forming in lower-energy settings.The association between transgression anddevelopment of rhodolithic facies is confirmedby observations of a modern rhodolith productionsite at Whangaparaoa Peninsula in NorthIsland, where algal nodules grow above aravinement surface cut during the Holocene sealevelrise, and also by a review of published fossilexamples, many of which show stratigraphicand compositional attributes analogous to thoseof the New Zealand occurrences. The reviewindicates that transgressive rhodolith accumulationsdevelop more commonly in, but are notrestricted to, non-tropical settings. It is suggestedthat a combination of factors, such as low netsedimentary input, nature of the substrate, sealevelrise and inherited physiography contributeto determine the relationship between rhodolithbearingdeposits and transgressive settings.2008040099贵 州 南 部 地 区 晚 石 炭 世 叶 状 藻 的 古 生 态 =Paleoecology of Late Carboniferous PhylloidAlgae in Southern Guizhou,SW China.

Halfar J; Steneck R S; Joachimski M;Kronz A; Wanamaker A D. Geology, 2008,36(6): 463-466Most high-resolution, proxy-based paleoclimateresearch has concentrated on tropicaloceans, while mid- and high-latitude marine regionshave received less attention, despite theirimportance in the global climate system. At present,sclerochronological analyses of bivalvemollusks supply the bulk of annual- to subannual-resolutionextratropical marine climate data,even though interpretation is complicated by aslowdown of growth with increasing shell age.Hence, in order to address the need for additionalhigh-resolution proxy climate data fromextratropical regions, we conducted the firstyear-long in situ field calibration of the corallinered alga Clathromorphum compactum in theGulf of Maine, United States. Coralline red algaeare widely distributed in coastal regions worldwide,and individual calcified plants can livecontinuously for several centuries in temperateand subarctic oceans. Stable oxygen isotopesextracted at subannual resolution from growthincrements of monitored specimens of C. compactumrelate well to in situ–measured seasurfacetemperatures during the May to Decembercalcification period, highlighting the suitabilityof coralline red algae as an extratropical climatearchive. Furthermore, there is a strong correlationbetween a 30 yr 18 O record of C. compactumand an instrumental sea-surface temperaturerecord (r = –0.58, p = 0.0008) and a proxyreconstruction derived from the bivalve Arcticaislandica collected in the central Gulf of Maine(r = 0.54, p = 0.002).2008040101阿 根 廷 火 地 岛 中 古 近 世 沟 鞭 藻 囊 胞 : 地 层 学和 古 环 境 学 = Middle Palaeogene dinoflagellatecysts from Tierra del Fuego, Argentina: biostratigraphyand palaeoenvironments. ( 英 文 ).Guerstein G R; Guler M V; Williams G L; FensomeR A; Chiesa, J O. Journal of Micropalaeontology,2008, 27(part 1): 75-94Palynological data from four surface sectionsin northern Tierra del Fuego, southern Argentina,provide a biostratigraphical and palaeoenvironmentalframework for the lower member of theLa Despedida Formation and the Cabo PenaFormation in their type areas. Selected dinoflagellatecyst (dinocyst) events indicate that the ageof the lower member of the La Despedida Formationis Middle Eocene and that of the CaboPena Formation is Late Eocene-earliest Oligocene.The age assigned to the La DespedidaFormation agrees with determinations based oncalcareous microfossils, but there is a potentialdiscrepancy regarding the Cabo Pena Formation.According to recent stratigraphic studies, theCabo Domingo Group, which includes the CaboPena Formation, is Late Eocene-Miocene in age.The palynomorph assemblages from the lower31
