Dating Methods and the Quaternary
c01.fm Page 1 Wednesday, March 23, 2005 3:21 AM 1 Dating Methods and the Quaternary Whatever withdraws us from the power of our senses; whatever makes the past, the distant or the future, predominate over the present, advances us in the dignity of thinking beings. Samuel Johnson 1.1 Introduction The Quaternary is the most recent period of the geological record. Spanning the last 2.5 million years or so of geological time1 and including the Pleistocene and Holocene epochs,2 it is often considered to be synonymous with the ‘Ice Age’. Indeed, for much of the Quaternary, the earth’s land surface has been covered by greatly expanded ice sheets and glaciers, and temperatures during these glacial periods were significantly lower than those of the present. But the Quaternary has also seen episodes, albeit much shorter in duration, of markedly warmer conditions, and in these interglacials the temperatures in the mid- and high-latitude regions may have exceeded those of the present day. Indeed, rather than being a period of unremitting cold, the hallmark of the Quaternary is the repeated oscillation of the earth’s global climate system between glacial and interglacial states. Establishing the timing of these climatic changes, and of their effects on the earth’s environment, is a key element in Quaternary research. Whether it is to date a particular climatic episode, to estimate the rate of operation of past geological or geomorphological processes, or to determine the age of an artefact or cultural assemblage, we need to be able to establish a chronology of events. -

An Attempt at Correlation of Main Climatostratigraphic Units of the Quaternary in the Marginal Zones of Continental Glaciations in Europe
ANNALES UNIVERSITATIS MARIAE CURIE-SKŁODOWSKA LUBLIN - POLONIA VOL.XLVIII, 14_____________________________ SECTIOB_____________________________________ 1993 Instytut Geologii Uniwersytetu Warszawskiego Leszek LINDNER, Leszek MARKS An Attempt at Correlation of Main Climatostratigraphic Units of the Quaternary in the Marginal Zones of Continental Glaciations in Europe Próba korelacji głównych jednostek klimatostratygraficznego podziału czwartorzędu w brzeżnej strefie zasięgu zlodowaceń kontynentalnych w Europie INTRODUCTION Studies of the Quaternary palaeogeographical evolution in the marginal zone of conti nental glaciations in Europe must be based on good knowledge of rhythmus of climatic changes in that time. Such changes in most cases were expressed by coolings that favou red development of 8 continental glaciations (Fig. 1) and warmings which were typical of climatic conditions during 7 interglacials, all during this part of the Quaternary that is na med the Pleistocene (Figs 2-4). From a climatostratigraphic point of view these glacia tions and interglacials, together with preceding main coolings and warmings of the Early Quaternary (Prepleistocene) as well as the following - the youngest warming of the Holo cene, are considered to be the main units of the inland Quaternary (M. D. Baraniecka 1990; L. Li n d n e r 1991b). These units are more and more frequently correlated with the 18O stages that record the main Quaternary climatic changes in deep-sea sediments (D.Q. Bowen 1989; D.Q. Bowen etal. 1989; L.Lindner 1984,1988a,b, 1991 a, b;F. Wiegank 1982; 1987; L. N. Voznyachuk 1985; V. A. Zubakov 1986, 1988, 1990; V. A. Zubakov and 1.1.

Kasse Introduction Excursion site Beerse is situated in northern Belgium, approximately 30 km east of Antwerp and 9 km west of Turnhout (fig. 8.1 ). The undulating coversand landscape is 25 to 30 m above sea level. In this region Early-Pleistocene deposits occur close to the surface. They dip towards the North Sea basin, where the base of the Quaternary deposits is found up to 900 m below the surface, which illustrates the rapid subsidence of the North Sea basin during the Quaternary (Zagwijn, 1989). South of the excursion site the Early-Pleistocene units have been eroded, because of uplift of Belgium. The Early Pleistocene units are covered by a thin layer (1-2 m) of mostly eolian sand from the Weichselian period. Late Early- and Middle-Pleistocene deposits are missing because of erosion, which is expressed at the excursion site by a gravel-bed on top of the Early-Pleistocene sediments (see excursion site 9: Meerle). Due to the Middle- and Late-Pleistocene uplift and erosion the so-called Campine microcuesta developed, which consists of Early-Pleistocene compact clay beds (De Ploey, 1961 ). The cuesta slope dips to the north (0.1 %), while the steeper cuesta front dips south (0.2-0.5%) towards the Nete river, which flows to the west and discharges into the Scheidt near Antwerp. -

However recent investigations, often based on novel methods including the analysis of 22 commercial 3-D seismic datasets, have begun to add further detail to knowledge of the North Sea 23 Pleistocene succession. Here, we review the Quaternary geology of the North Sea area, summarising 24 the evidence for extents, configurations, and timing of former glacial activity, focusing attention on 25 key sites across the basin, and for the first time, integrating the stratigraphy with up-to-date 26 information on the geomorphic (morphological) framework of the Pleistocene sequence. -

Quaternary stratigraphy and palaeogeography of Poland. Acta Geo- logica Polonica, 66 (3), 403–427. Warszawa. Though the stratigraphical and palaeogeographical framework of the Quaternary in Poland is still to be completed, several crucial points have been confirmed recently. The preglacial series, accepted for years as belonging to the Lower Pleistocene, is undoubtedly of Early Pliocene age, with a huge hiatus above almost until the uppermost Lower Pleistocene. The earliest glaciation in Poland (Nidanian) occurred at about 900 ka BP when the ice sheet reached the mid-southern part of the country. The following Podlasian Interglacial embraced the Brunhes/Matuyama boundary in the middle, in a similar fashion to the corresponding Cromerian Complex in Western Europe. The late Early and early Middle Pleistocene interglacials in Poland comprised 2-3 optima each, whereas every one of the younger interglacials was characterised by a single optimum only. -

S. COOKE Department of Geology, Dalhousie University, Halifax, N. S. Introduction Although coring devices capable of collecting stratified samples from the deep sea floor were developed forty years ago, it is mainly in the last decade that major syntheses of stratigraphic data from many such cores have been undertaken. The recognition of alternating "warm" and "cold" microfaunas in the cores invites comparison with the records of glacial and interglacial events on the continents and it might be anticipated that correlations would soon emerge. -
Polish Pleistocene Stratigraphy - a Review of Interglacial Stratotypes
Netherlands Journal of Geosciences — Geologie en Mijnbouw | 84 - 2 | 61 - 76 | 2005 Polish Pleistocene stratigraphy - A review of interglacial stratotypes A. Ber | Polish Geological Institute, 00-975 Warsaw, Rakowiecka 4 Str., Poland. Email: [email protected] Manuscript received: February 2004; accepted: January 2005 Abstract | The Pleistocene stratigraphy of Poland is based on palynological analyses of buried organic lake sediments and dating with radiocarbon or thermoluminescence (TL), as well as on the lithologic-petrographical analyses of tills and other glacigenic deposits to which TL-dating was also applied. Rarely were sediments of the stratotype interglacial profiles to which palaeomagnetic methods and TL-dating were applied, examined by mineralogical, chemical and isotopic 5180 and 513C analyses, except the Augustovian, Mazovian and Eemian interglacials. The data was recorded in both exposures and boreholes. Overall, tills of 8 glaciations have been identified: Narevian (Menapian), Nidanian, Sanian 1 (Elsterian 1), Sanian 2 (Elsterian 2), Liviecian (Fuhne), Krznanian (Drenthe), Wartanian (Warthe) and Vistulian (Weichselian). Substantial palynological evidence with complete pollen sequences and absolute dating exists for organic sediments of five interglacials: Augustovian (Bavelian Complex or Cromerian I), Ferdynandovian (Voigtstedt), Mazovian (Holstein), Zbojnian (Domnitz) and Eemian. Other interglacials, i.e. Malopolanian (Cromer Complex - II or III Interglacial) and Lubavian (Schbningen) are not sufficiently supported -
Stratigraphy and Paleoecology of the Late Pliocene and Early Pleistocene in the Open-Cast Mine Hambach (Lower Rhine Basin)
Netherlands Journal of Geosciences / Geologie en Mijnbouw 81 (2): 193-199 (2002) Stratigraphy and paleoecology of the Late Pliocene and Early Pleistocene in the open-cast mine Hambach (Lower Rhine Basin) G. Heumann1 &Th. Litt1 1 Institut fur Palaontologie der Universitat Bonn, Nussallee 8, 53115 Bonn, Germany e-mail: [email protected], [email protected] (corresponding author) Manuscript received: December 2000; accepted: January 2002 Abstract More than 400 samples for paleobotanical and sedimentological investigations were collected from Late Pliocene and earliest Pleistocene beds in the open-cast lignite mine Hambach. They were analysed to obtain information about the paleoecology and paleoclimate of this time interval. The sedimentation type changed from a high-energy meandering fluvial system to floodplain, swamp and oxbow lake sedimentation. The typical Tertiary floral elements decreased with the onset of increasingly cooler climatic conditions and disappeared at the beginning of the Pleistocene to be substituted by a impoverished and cold- adapted flora. These combined litho- and biostratigraphic investigations led to an improved and reproducible separation of Late Pliocene from Early Pleistocene deposits.

Stratigraphy and Extents of Pleistocene Continental Glaciations in Europe
acta geologlca polonica Vol. 38, No. 1-4 Warszawa 1988 LESZEK LlNDNER Stratigraphy and extents of Pleistocene continental glaciations in Europe ABSTRACT: Evidence is presented for subdivision of the Quaternary in Central Europe into 8 continental glaciations (Narew = Menap; Nida = Glacial A; San 1 = Glacial B = Elster 1; San 2 = Elster 2; Liwiec = Fuhne; Odra = Drenthe = Saale 1 + 2; Warta = Warthe = Saale 3; Wisla = Weichsel = Vistulian) separated by 7 interglacials (podlasian = Cromerian I; Malopolanian = Cromarian 11; Ferdynand6w = Cromerian III + W = Voigtstedt; Mazovian = . Holstein s.s.; Zb6jno = Domnitz; Lubawa = Riigen; Eemian). All glaciations were expressed by advances of Scandinavian icesheets onto the territory of Poland. There is still no evidence of the presence of one (? or two) earliest glaciations and also of the Liwiec Glaciation in the West European Lowland. During the Liwiec Glaciation the Scandjnavian icesheet has not advanced the East European Lowland, similarly as it did not occupy the East Russian Plain during the Nida Glaciation. In the British Isles the first three glaciatiQns were expressed by a development of local ice caps. During the successive glaciations (San 2 = Anglian; Odra = Wolstonian; Wisla = Devensian) these caps expanded so much that they contacted with the Scandinavian icesheet. INTRODUCTION Studies of the Quaternary in Europe are mainly focused on investigations of continental (Scandinavian) glaciations and separating interglacials. Separa tion of these units, their age and extents as well as paleontologic documenta tion supply with principal data for reconstruction of the rhythm of main climatic changes during the Quaternary (cl KUKLI\. 1977, ZUBAKOV & BORZENKOVA 1983, LINDNER 1984, BOW EN & at. 1986, BRUNN ACKER 1986, SHOTTON 1986, ZAGWUN 1986).
