Abstract:

Dari bor inti pada EKSPEDISI IMAGES, di Samudra Hindia, telah diteliti sebanyak 21 percontoh sedimen dari lokasi MD 982152, dan 29 buah dari lokasi MD 982155 untuk kepentingan biostratigrafi berdasarkan analisis foraminifera plankton dalam interval 1,5 meter. Pada kedua penampang bor inti tersebut hanya dijumpai satu zona foraminifera plankton Kuarter, yaitu Zona Globorotalia truncatulinoides. Untuk MD 982152, zona ini bisa dibagi ke dalam dua subzona, yakni Subzona-subzona Globorotalia crassaformis hessi dan Globigerinella calida, sedangkan untuk MD 982155, zona tersebut bisa dibagi lagi ke dalam tiga subzona, yakni Subzona-subzona Globorotalia crassaformis hessi Globigerinella calida, dan Beella digitata. Kejadian yang signifikan di kedua penampang itu adalah Datum Pemunculan Pertama dari Globigerinella calida dan Pemunculan Akhir dari Globorotalia crassaformis hessi. Pada MD 982155, dijumpai Pemunculan Pertama dari Beella digitata. Kata kunci: foraminifera plankton, Kuarter, biostratigrafi, Samudra Hindia. From IMAGES Expedition in Indian Ocean, 21 samples from MD 982152, and 29 samples from MD 982155 had been studied for the purpose of biostratigraphy based on planktonic foraminifera within 1,5 meter interval. In both sections, only one Quaternary zone is found, namely Globorotalia truncatulinoides Zone. For MD 982152, that zone can be subdivided into two interval subzones e.g. Globorotalia crassaformis hessi and Globigerinella calida calida. However, in MD 982155 Globorotalia truncatulinoides Zone can be subdivided into three subzones namely, Globorotalia crassaformis hessi, Globigerinella calida calida, and Beella digitata Subzones. The planktonic foraminifera event revealed in both sections are the First Appearance Datum (FAD) of Globigerinella calida calida and the Last Appearance (LAD) of Globorotalia crassaformis hessi. In MD 982155 the FAD of Beella digitata is found. Keywords: planktonic foraminifera, Quaternary, biostratigraphy, Indian Ocean.

Abstract:

I find myself in the position of discussing a rather unfortunate misnomer. In the first place, topics that traditionally have been called “quantitative biostratigraphy” seldom deal with quantities of anything. In the second place, much of “quantitative biostratigraphy” deals more with chronostratigraphy and geochronology than with biostratigraphy. The operational concept is time, not fossil content, although, of course, the fossil content is the starting point. Nonetheless, the phrase “quantitative biostratigraphy” is quite firmly entrenched in the working vocabulary and I will use it here. I will focus on three very different techniques that all involve stratigraphic correlation based on the ranges of fossils.

Abstract:

The Eocene carbonates of the south Sabzevar region in central Iran hold a rich Alveolina assemblage.Nine species including A. globula, Alveolina sp. 1, Alveolina aff. globula, A. regularis, A. globosa, A. pasticillata, A. laxa, A. pisiformis and A. cf. decipiens are identified through detailed analysis in thin section. The biostratigraphy obtained points to the early Ypresian Shallow Benthic Zones SBZ6 and partly SBZ7, indicating the occurrence of a lower Eocene carbonate system. The Alveolina biostratigraphy is correlated to the calcareous nannofossil biostratigraphy, and is assignable to the middle part of the NP10 Zone and especially with the CNE2 biozones. The evolutionary trends of A. globula and its dispersal through thewestern and central Neo-Tethys Ocean during theYpresian is here considered in relation with the occurrence of Alveolina sp. 1.

Abstract:

This first study on chitinozoans from Greenland has revealed representatives of twenty-two chitinozoan species recovered from Ordovician and Silurian beds in North Greenland. The Ordovician faunas are sirnilar to those described from North Arnerica, while the Silurian faunas are more sirnilar to those of Baltoscandia. Four distinct assemblages can be separated between Maysvillian - early Garnachian and Ludlow. The chitinozoan biostratigraphy is in agreement with that of the graptolites but differs from the conodont biostratigraphy.

Abstract:

The last decade saw a revival of the debate on the exact stratigraphical position of the Upper Ordovician P. linearis graptolite biozone. Chitinozoan biostratigraphy can be useful to help address this question. Here, we provide a high-resolution chitinozoan biostratigraphy through the Dicellograptus Shale Formation at Vasagård on the Island of Bornholm (Denmark), which recently also was subject to a thorough revision of its graptolite fauna, representing the Dicellograptus folicaceus, Dicranograptus clingani and Pleurograptus linearis biozones. We have identified close to 9000 individual chitinozoan vesicles from 26 samples through the upper c. 9m of the Dicellograptus Shale Formation. The Spinachitina cervicornis, Fungochitina spinifera and Tanuchitina bergstroemi chitinozoan biozones are identified, and their boundaries carefully calibrated against the revised graptolite biostratigraphy. A correlation with the chitinozoan biozonation in the British Cautley district, which has a predominantly Baltoscandian, mid-latitude signature and is well-correlated with the graptolite and shelly fauna biozones described from the historical type region, is established.

Abstract:

Abstract. The integrated use of calcareous nannofossil and dinoflagellate cyst events in a study of the late Pliensbachian–early Toarcian interval in central Italy has yielded a high resolution biostratigraphy. The use of both the first and last occurrences of selected taxa belonging to the two phytoplankton groups allows the dating of the sediments with a very refined detail, even when lithologies are unfavourable to the preservation of one fossil group. The evolutionary history of calcareous nannofossils and dinoflagellate cysts during the early Jurassic and its links with global events are responsible for the high potential of this integrated biostratigraphy.

Abstract:

Using new palaeomagnetic and biostratigraphic data, we revise the age-model for the middle Eocene, deep-marine Aínsa Basin (Spanish Pyrenees), a tectonically active basin formed at a convergent-plate margin. This new age model provides a framework for evaluating the depositional history and sediment accumulation rates. New integrated magneto- and biostratigraphy data identify two normal and two reverse chrons of the geomagnetic polarity timescale (C21r, C21n, C20r, C20n) and place these Upper Hecho Group deposits in the middle Eocene (Lutetian). Nannofossil analysis identifies a biostratigraphic range from Subzone NP14b in the Gerbe System to Subzone NP15b at the top of the Aínsa System using key, age-diagnostic marker species such as Blackites inflatus, Blackites piriformis and Coccolithus gigas. We also present new nannofossil biostratigraphy from the Lower Hecho Group. This new Aínsa Basin chronostratigraphy enables inter-basinal correlations between the proximal fluvio-deltaic Tremp-Graus Basin and the more distal Jaca Basin, thereby providing a better understanding of the basin evolution.Supplementary materials: Field photographs of the sampled sections, magnetostratigraphic results, biostratigraphy results, alternative age model scenario and discussion on previous age model are available at https://doi.org/10.6084/m9.figshare.c.5083076

Abstract:

Two new species, Calcidiscus salamis sp. nov. and C. odebodea sp. nov. are described from themarine offshore Niger Delta Neogene sequence. Calcidiscus salamis is structurally similar to C. fuscus but has a closed central area. Calcidiscus odebodea differs from C. leptoporous in having strongly curved sutures. The new forms consistently occur throughout the LateMiocene to Early Pliocene offshore eastern and western Niger Delta sequences. They have the same stratigraphic range: NN11-NN13 zones (Messinian to Zanclean). The combination of their widespread geographic occurrence and short stratigraphic rangemakes them excellent index species for the high-resolution biostratigraphy of theNiger Delta marine offshore sequences where most Calcidiscus forms have much longer ranges.

Abstract:

Abstract. A sequence stratigraphic analysis of well log, seismic, and biostratigraphic data has documented a pattern of cyclic sedimentation for the Palaeogene of the Central North Sea. Previously published research has also documented cyclic sedimentation related to sea level changes. Integrating Central North Sea subsurface sections with Palaeogene outcrop from NW Europe, using sequence stratigraphic first principles and the graphic correlation method, has produced a chronostratigraphic framework for the Palaeogene of NW Europe.Northwestern Europe basins (London–Hampshire, Paris, and Belgian) have shallow marine to nonmarine environments, revealing basinward and landward fades shifts indicating sea level changes. The problem correlating NW Europe with North Sea deposits has been addressed by correlating a biostratigraphy to the deep water deposits outcropping in Denmark. Once a biostratigraphy joining the subsurface and outcrops is built, key bounding surfaces are correlated between basins. We find that: (1) sedimentation in the deep basin occurs as depositional pulses, separated by time-correlative biostratigraphic data terraces (hiatal intervals), which correspond to persistent seismic reflectors; (2) not all sequence boundaries are resolvable by graphic correlation, but the method brackets packages defined by seismic, log interpretation and biostratigraphy; and (3) correlation with outcrops reveals the true significance of the hiatal intervals.

Abstract:

A rich larger foraminifera assemblage from the Eocene carbonates of the south Sabzevar region (Now-Deh section) in central Iran indicates a late Ypresian to early Lutetian age. Nine species of Alveolina d’Orbigny are studied for systematics and biostratigraphy. The assemblage includes A. minuta, A. decastroi, A. cremae, A. cremae elongata, A. decipiens ayrancensis, A. celali, A. rugosa, A. cuspidata, A. frumentiformis. We have also found nummulitids (genus Nummulites and Assilina) and orthophragmines identified as N. campesinus, N. praediscorbinus, A. placentula, A. praespira, A. reicheli, A. ex. intrec. laxispira-maior and Discocyclina archiaci bartholomei. The recovery of Alveolina cremae elongata, A. decipiens ayrancensis, A. celali, A. rugosa, A. cuspidata and Assilina praespira has permitted for the first time to extend their geographical distribution outside of the classical peri-Mediterranean area to the central Tethys regions. The obtained biostratigraphy points to the Shallow Benthic Zones SBZ11 to SBZ13, indicating the occurrence of a Lower–Middle Eocene carbonate system. Part of the age model is supported by the calcareous nannofossil biostratigraphy that belong to the NP14b and CNE8 biozones, recorded from the central portion of the studied section. Issues regarding the application of the SBZ into the Middle East domains are discussed in terms of relative stratigraphic position and biogeographic dispersal of some significant Alveolina species.

Abstract:

As the result of a study integrating lithostratigraphy and biostratigraphy of the Upper Paleocene (Thanetian) and Lower Eocene (Sparnacian-Ypresian) of the Paris Basin, a new lithostratigraphic unit, the Mont Bernon Group, can be formally recognized. The group includes four formational units: the Mortemer (Mortemer Limestone), the Vaugirard (Plastic Clay), the Soissonnais (Lignitic Clay of Soissons) and Epernay (Lignitic Clay of Epernay) formations and associated members. An integration of charophyte, dinoflagellate cyst and, to a lesser extent, calcareous nannoplankton biostratigraphy allows us to place the succession in an approximate, integrated biostratigraphic framework. Our introduction of a formal lithostratigraphic framework for the Upper Paleocene-Lower Eocene succession in the Paris Basin contributes to emphasize the distinctiveness of the Sparnacian deposits as an independent stratigraphic unit.

Abstract:

Real-time well site biostratigraphy monitors the stratigraphic progress of drilling wells and can show if the well is conforming or deviating from predicted stratigraphy; it can also show whether total depth criteria have been met. New technology implemented by BHP Billiton Petroleum on wells in the Gulf of Mexico make it possible to undertake well site biostratigraphy remotely. An automated microscope has been developed that can scan and photograph nannofossil slides at a quality almost indistinguishable from conventional microscopy. A technician present at the well makes a slide from ditch cuttings and places it on the microscope, where software scans the slide at several focus levels, compresses the files and transfers the images to the office. A biostratigrapher in the office looks at the images and makes taxonomic identifications. When implemented on the first well, the technology provided immediate results by being the first data acquisition process to recognise that a section was faulted out. Remote well site biostratigraphy also creates a verifiable record, making it possible to quality-control biostratigraphic interpretations; it also frees up space on the rig and improves health and safety for biostratigraphers. Delays in file transfers from the rig to the office are being addressed by reducing the size of the image files by discriminating the fossils from the background.

Acta Geologica Polonica, 63 (2), 223-237. Warszawa. The foraminiferal and radiolarian biostratigraphy of selected sections of the Zabijak Formation, the youngest sediments of the Tatra massif (Central Western Carpathians), have been studied. Benthic foraminifers, mainly agglutinated species, occur abundantly and continuously throughout the studied succession, while planktic foraminifers are generally sparse. Five planktic and two benthic foraminiferal zones have been recognized. The marly part of the Zabijak Formation comprises the Pseudothalmanninella ticinensis (Upper Albian) through the Rotalipora cushmani (Upper Cenomanian) planktic foraminiferal zones, and the Haplophragmoides nonioninoides and Bulbobaculites problematicus benthic foraminiferal zones. The radiolarians were recognized exclusively in the Lower Cenomanian part of the formation.

Abstract:

The vertebrate fauna of the Leisey Shell Pit near Tampa Bay, Florida, represents one of the more significant Irvingtonian mammalian faunas of North America. The fossil vertebrates occur in thin bone beds bounded above and below by massive shell beds containing a rich invertebrate (chiefly molluscan) fauna. Debate has arisen concerning the precise age of the faunas at Leisey. Although generally agreed to be Pleistocene, estimates based upon vertebrate biostratigraphy suggest a somewhat older age than do estimates based upon molluscan biostratigraphy. To help resolve this controversy, 87Sr/86Sr ratios were determined on molluscan shells throughout the section. These ratios were then correlated to the global sea water 87Sr/86Sr curve for age detemination. The Sr isotopes support an early Pleistocene age for the vertebrate fauna and suggest a complex history for the shell accumulations.

Abstract:

Dispersed megaspores are known from almost all the Gondwana horizons though they are comparatively rare. Approximately, 36 genera and 110 species are known from the Gondwana sediments. The number of genera and species is almost equally divided between Permian and Mesozoic Gondwana. Most of the formations except Talchir, Barren Measures and Upper Tiki have marker megaspore taxa at generic level. The above-mentioned three formations have marker taxa only at the species level. At the present stage of our knowledge megaspores are found useful only for broader zonation. As far as age determination is concerned, the megaspores, as compared to other palynofossils, indicate younger ages.

Abstract:

AbstractRugose corals are one of the major fossil groups in shallow-water environments. They played an important role in dividing and correlating Carboniferous strata during the last century, when regional biostratigraphic schemes were established, and may be useful for long-distance correlation. Carboniferous rugose corals document two evolutionary events. One is the Tournaisian recovery event, with abundant occurrences of typical Carboniferous rugose corals such as columellate taxa and a significant diversification of large, dissepimented corals. The other is the changeover of rugose coral composition at the mid-Carboniferous boundary, which is represented by the disappearance of many large dissepimented taxa with complex axial structures and the appearance of typical Pennsylvanian taxa characterized by compound rugose taxa. The biostratigraphic scales for rugose corals show a finer temporal resolution in the Mississippian than in the Pennsylvanian, which was probably caused by the Late Paleozoic Ice Age that resulted in glacial–eustatic changes and a lack of continuous Pennsylvanian carbonate strata. The Pennsylvanian rugose corals are totally missing in the Cimmerian Continent. High-resolution biostratigraphy of rugose corals has so far only been achieved in few regions for the Mississippian timescale. In most regions, more detailed taxonomic work and precise correlations between different fossil groups are needed.

Abstract:

The Cretaceous record of the diatoms presented here outlines our understanding of their early morphological development. Recent documentation of well preserved Lower Cretaceous (Aptian/Albian) diatom assemblages provides a window into the early history of the diatoms and serves as a base for comparing their subsequent morphological changes. A brief review of diatom biology and morphology is provided to introduce this paper and that of Barron and Baldauf (this volume). Additional background information on the diatoms can be found in the works of Schrader and Schuette (1981), Tappan (1980), Bach and Burkhardt (1984), Barron (1985a, 1993), Fenner (1985), Ricard (1987), Bradbury (1988), Round et al.

Abstract:

Abstract. INTRODUCTIONIn May 1989 a British Micropalaeontological Society Symposium Meeting was held at the University of East Anglia under the title “Cenozoic Biostratigraphy and Global Change”. Fourteen lectures were given on this theme, many of them originating from investigations of DSDP/IPOD and ODP (Ocean Drilling Program) samples. All addressed the potential of micropalaeontological observations for interpreting the history of global and regional oceanographic and climatic change. Many results of this type of investigation are currently appearing in science journals such as “Paleoceanography” and “Palaeogeography, Palaeoclimatology, Palaeoecology” as well as in the “Proceedings of the Ocean Drilling Program”. British micropalaeontologists are taking an active part in this research, but relatively few of the resultant papers have so far appeared in the Journal of Micropalaeontology.Many of the lectures given at the May 1989 Symposium represented work already recently published, or due to be subsequently published in the Proceedings of the Ocean Drilling Program. Four papers, representing ongoing research not then due to be published, have been brought together here as a small thematic set, illustrating a variety of approaches to “Cenozoic Biostratigraphy and Global Change”. They range across Ostracoda, Coccolithophorida, Planktonic and Benthic Foraminifera, through the entire Cenozoic, including the latest Quaternary, and they include results from both the North Atlantic and Pacific oceans.TITLES“Global Change and the Biostratigraphy of North Atlantic Cenozoic deep water Ostracoda” - Robin C.
