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. -

Through much of this period, the Earth's northern and southern regions were covered by kilometer thick glaciers. It is important to recognize that the Pleistocene was a series of real ice ages, separated by relatively short interglacial periods. The Pleistocene started 2.6 million years ago and lasted until the termination of the Weichsel glaciation about 11,711 years ago. Timeline of Earth's geological periods. Time progresses from right to left. The glowing inferno just after Earth was formed is named Hadean. In Archean water condensed and an atmosphere of nitrogen and methane was formed together with the first rocks that we know about. In Proterozoic cyano bacteria produced oxygen, which oxidized iron and methane, in the end of the period life emerged on the seabed. Phanerozoic represents the era in which there have been visible tangible life. It is divided in Paleozoic, Mesozoic and Cenozoic. Paleozoic was the period of early life. Mesozoic was the time of the dinosaurs, and Cenozoic is the era of mammals, which latter further is divided into Tertiary and Quaternary. -

Vegetation and Climate Changes at the Eemian/Weichselian Transition: New Palynological Data from Central Russian Plain
Polish Geological Institute Special Papers, 16 (2005): 9–17 Proceedings of the Workshop “Reconstruction of Quaternary palaeoclimate and palaeoenvironments and their abrupt changes” VEGETATION AND CLIMATE CHANGES AT THE EEMIAN/WEICHSELIAN TRANSITION: NEW PALYNOLOGICAL DATA FROM CENTRAL RUSSIAN PLAIN Olga K. BORISOVA1 Abstract. Palynological analysis of core Butovka obtained from the Protva River basin 80 km south-west of Moscow (55º10’N, 36º25’E) provides a record of vegetation and climate change in the central Russian Plain spanning the Last Interglacial and the beginning of the following glacial epoch. Pollen profiles of the Mikulino (Eemian) Interglaciation in the Central Russian Plain show a distinctive pattern of the vegetation changes, reflecting an increase in temperatures to- wards the optimum phase of the interglaciation followed by a gradual cooling. Rapid climatic deterioration, manifesting an onset of the Valdai (Weichselian) Glaciation, took place after a slower cooling accompanied by increasing humidity of climate during the post-optimum part of the Mikulino Interglaciation. The interglacial/glacial transition had a com- plex structure, being marked by a sequence of secondary climatic oscillations of varying magnitude. A decreasing role of mesophilic plants and an increase in abundance and diversity of the xerophytes and plants growing at present in the re- gions with highly continental climate in the Butovka pollen record suggests that during the Early Valdai the climate grew both more continental and arid. With this tendency at the background, two intervals of climatic amelioration can be dis- tinguished. Both of them are marked by the development of the open forest communities similar to the contemporary northern taiga of West Siberia. -
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.

Detailed sedimentology determined not only genesis of ice-contact (Welland) and glaciolacustrine (Nene) deposits but also provided insight on lake surface water levels. The ice-contact deposits recorded a constant lake level at the same height as alluvial remnants upstream in the Wel- land valley. These alluvial remnants are located where present tributaries join the Welland, indicating they were formed where influent streams entered a former lake and therefore can be interpreted as fluvial terraces resulting from local base- level rise. The glaciolacustrine deposits in the Nene valley recorded fluctuating lake levels, indicating that altitudinally separated sand and gravel bodies coinci- dent with these fluctuations and located where influent streams entered the lake also can be interpreted as fluvial terraces, but resulting from fluctuating baselevel. -
Pleistocene Glacial Limits in the Territory of Poland
Przegl¹d Geologiczny, vol. 53, nr 10/2, 2005 Pleistocene glacial limits in the territory of Poland Leszek Marks* Abstract.Thelimitsoffourmajoricesheets can be traced in the present landscape of Poland. Glacial deposits and ice-dammed lakes indicate a stream-like pattern of advancing ice bodies, dependent both on ice dynamics in the marginal zones and on the pre-existing landscape in their forefields. The southernmost extent of the Pleistocene ice sheets is indicated by the Scandinavian erratics and was formed by the South Polish Glaciations (Elsterian), partly replaced in the west by the Odranian of the Middle Polish Glaciations (Saalian I). The subsequent Wartanian Glaciation of the Middle Polish Glaciations (Saalian II) and the Vistulian Glaciation (North Polish Gla- ciation, Weichselian) were limited to areas further to the north. Key words: Pleistocene, glaciation limits, palaeo-ice streams Poland Systematic cartographic works, already carried 500km through for many years in Poland, supplied with abundant Estonia geological information that has been only partly used for geological maps, firstly the Geological Map of Poland in scale 1 : 200,000 and the Detailed Geological Map of Poland in scale 1 : 50,000.

Preliminary Analysis of European Small Mammal Faunas of the Eemian Interglacial: Species Composition and Species Diversity at a Regional Scale
Article Preliminary Analysis of European Small Mammal Faunas of the Eemian Interglacial: Species Composition and Species Diversity at a Regional Scale Anastasia Markova * and Andrey Puzachenko Institute of Geography, Russian Academy of Sciences, Staromonetny 29, Moscow 119017, Russia; [email protected] * Correspondence: [email protected]; Tel.: +7-495-959-0016 Academic Editors: Maria Rita Palombo and Valentí Rull Received: 22 May 2018; Accepted: 20 July 2018; Published: 26 July 2018 Abstract: Small mammal remains obtained from the European localities dated to the Eemian (Mikulino) age have been analyzed for the first time at a regional scale based on the present biogeographical regionalization of Europe. The regional faunas dated to the warm interval in the first part of the Late Pleistocene display notable differences in fauna composition, species richness, and diversity indices. The classification of regional faunal assemblages revealed distinctive features of small mammal faunas in Eastern and Western Europe during the Eemian (=Mikulino, =Ipswichian) Interglacial. Faunas of the Iberian Peninsula, Apennine Peninsula, and Sardinia Island appear to deviate from the other regions. In the Eemian Interglacial, the maximum species richness of small mammals (≥40 species) with a relatively high proportion of typical forest species was recorded in Western and Central Europe and in the western part of Eastern Europe. The lowest species richness (5–14 species) was typical of island faunas and of those in the north of Eastern Europe. The data obtained make it possible to reconstruct the distribution of forest biotopes and open habitats (forest-steppe and steppe) in various regions of Europe. Noteworthy is a limited area of forests in the south and in the northeastern part of Europe.
