Chronology of the Last Deglaciation in the Southeastern Baltic Region on the Basis of Recent OSL DatesThe study of the deglaciation chronology in the south-eastern Baltic Region belonging to the outer zone of the last Pleistocene glaciation has a long history. The Finnish investigator H. Hausen (1913) who worked in the north-western portion of the East-European Plain at the beginning of the 20thcentury was the first to attempt a reconstruction of the course of glacial retreat during the last glaciation. At that time investigators had no physical dating methods and the time scale based on varvometric method, introduced by the Swedish geologist G. de Geer (1912) who divided the deglaciation history of Scandinavia into Daniglacial, Gotiglacial and Finiglacial, each of which had different palaeoglaciological conditions. During last decades different dating methods, including14C, ESR, luminescence methods and10Be techniques have been used, but they could not help essentially improve the existing stratigraphical charts and many problems of topical interest in the history of deglaciation have not been solved yet. During last years the first two authors have studied the suitability of OSL method for the geochronological purposes, paying the most attention to the waterlaid sediments. In the first step they have found the most promising genetical varieties of glaciofluvial sediments (glaciofluvial deltas and sandurs) and in this paper they widened the study area to all three Baltic states with close cooperation with Latvian and Lithuanian colleagues. The obtained results demonstrated, that not all mineral grains in the uppermost glaciofluvial and glaciolacustrine sediments were fully bleached during the last deglaciation. Probably the older sediments also influenced to the luminescence results. It means, that stratigraphic conclusions based on single dates or their small sets are inadmissible and in each case luminiscence dating requires a verification using other methods.

A lot of work has been devoted to the study of the coastal zone of the southern coast of the Barents Sea. However, they are mainly devoted to the period of deglaciation of the territory and the subsequent marine transgressions. The Holocene period was less interesting for researchers, because it was believed that the coast was stabilizing by this time and almost no significant changes were taking place. In recent years, interest in the dynamics of the coastal zone of the last millennia is mainly associated with the problem of climate change and the melting of Arctic ice in the modern period. In this regard, the study of new sequences of the coastal zone of the Barents Sea is especially relevant. Recently, new studies of the Holocene history of the coastline of the northwestern coast of the Kola Peninsula have appeared, which change some prevailing ideas about the dynamics of the coastline in the Holocene period. The presented review is caused by the need to summarize new results and existing ideas.

The material in the article contains biographical information from the life and scientific activity of the doctor of geological and mineralogical sciences, professor, academician Academy of Sciences of the USSR A.D. Arkhangelsky. A wide range of the scientist is shown and a description of the main directions of research in the field of regional geology, fauna and stratigraphy of the Paleogene and Upper Cretaceous deposits of the Volga and Central Asia, lithology and paleography, issues of tectonics and the relationship of gravitational and magnetic anomalies with the geological structure of the territory of the USSR is given. The main attention is paid to his work in the study of the geology of oceans and seas. The main contribution of the scientist to the study of Mesozoic bauxites, their structure and mineral composition is described. On this basis, the scientist developed and substantiated a new sedimentary theory of their formation. This theory opened the possibility for geologists to approach the study of bauxite as sedimentary rocks; this played an important role in the search for new deposits of this valuable mineral. The complex of geological and geophysical work carried out by him on expeditions along the East European Plain provided an answer to important questions about the distribution of oil, coal and iron ores on the territory of the Russian Platform. Much attention was paid to the study of the geology of the Black Sea. Processing materials collected by a hydrographic expedition and a comparative study of the columns of the Black Sea silt and oil-bearing sediments of the Crimean-Caucasian region led the scientist to important conclusions about the conditions of accumulation of oil-producing suites. Long-year research A.D. Arkhangelsk sediments of the Black Sea, their lithology, geochemistry, structure, subsequent changes and deformations were summarized in a number of works, among which are “Conditions for the formation of oil in the North Caucasus” (1927), “Geological history of the Black Sea” (1932), “Geological structure and the history of the development of the Black Sea“ (1938), written together with N.M. Strakhov. In 1926—1928 Arkhangelsky lead the field geological survey work on the Kerch Peninsula for the study of oil fields.

The Ixil Maya area is located in Quiche Department of the north-western part of the Guatemalan Highlands. It has witnessed a continuous occupation since the 1st millennium BC till today. This archaeologically interesting region has provided many important discoveries of rare cultural mixture, with distinct features typical for both Maya Highlands and more distant Lowlands. Recently, the scholarly interest has focused on Chajul where a few years ago, in one of the local houses, well preserved wall paintings dated to the Colonial period were exposed by the house owner during the process of its renovation. With this extraordinary finding a question emerged - are we able to confirm the cultural continuity between the pre-Columbian settlers and modem Ixil who claim «to be always here»? This paper presents a brief outline of the history of the Ixil Maya. It also presents results of some recent and preliminary studies conducted by Polish scholars in this region.

Introduction. History of the North-West area of Novgorod land at the end of the XV century attracted the attention of researchers mainly in the socio-economic aspect. This is due to the fact that Novgorod scribal books are dated by the end of the XV century. From the standpoint of socio-economic history their value is not in doubt, but from an ethno-historical point their onomastic content is underestimated. Materials and methods. The main source of research was the scribe book of the Vodskaya Pyatina 1499/1500. The descriptive method of research is to identify and record the Baltic-Finnish oikonyms (names of rural settlements) and anthroponyms mentioned in the scribe books. Baltic-Finnish anthroponyms are identified on the basis of an analysis of formal indicators of borrowing the anthroponyms. Results and Discussion. There are several areas where the Baltic-Finnish oikonymy and anthroponymy were concentrated, namely Korboselsky graveyard in the northern Prinevye, Lopsky and Terebuzhsky graveyards in the southern Ladoga, as well as Dudorovsky and Izhora graveyards south of the Neva. Archaeological sources record a significant presence of the Izhora antiquities. The presence of Karelians is noted in the northern Prievye and southern Ladoga. Slavic onomastic materials are recorded throughout Orekhovsky and Ladoga counties, but to mostly in the cities of Oreshka, Ladoga and their nearest areas. Conclusion. By the end of the XV century the north-western graveyards of Novgorod land were inhabited by representatives of various ethnic groups: Slavs, Vodians, Izhora and Karelians, as evidenced by the data of anthroponyms and toponyms of the scribe’s books and confirmed by archaeological sources.

AbstractThe woolly mammoth (Mammuthus primigenius) was widespread in almost all of Europe during the late Pleistocene. However, its distribution changed because of population fluctuations and range expansions and reductions. During Marine Oxygen Isotope Stage 2 (MIS 2), these processes were highly dynamic. Our analyses of 318 radiocarbon dates from 162 localities, obtained directly from mammoth material, confirmed important changes in mammoth range between ~28.6 and ~14.1 ka. The Greenland stadial 3 interval (27.5–23.3 ka) was the time of maximum expansion of the mammoth in Europe during MIS 2. The continuous range was soon fragmented and reduced, resulting in the disappearance of Mammuthus during the last glacial maximum from ~21.4 to ~19.2 ka in all parts of the North European Plain. It is not clear whether mammoths survived in the East European Plain. The mammoth returned to Europe soon after ~19.0 ka, and for the next 3–4 millennia played an important role in the lifeways of Epigravettian societies in eastern Europe. Mammoths became extinct in most of Europe by ~14.0 ka, except for core areas such as the far northeast of Europe, where they survived until the beginning of the Holocene. No significant correlation was found between the distribution of the mammoth in Europe and human activity.

<p>A detailed pedocryostratigraphic scheme of the Late Pleistocene periglacial region of the East European Plain has been developed on the basis of study of the paleorelief, sediments, paleosols, and cryogenic horizons. OSL and <sup>14</sup>C-dating of paleosols and sediments in Aleksandrov quarry and in other sections made it possible to substantiate this scheme and correlate it with analogous ones for different regions of Europe. The loess-paleosol sequence in Aleksandrov quarry (51º05'N, 36º08'E) does not have an analogous with respect to the completeness in the whole East European Plain. In the filling of paleobalka the Ryshkovo paleosol of the Mikulino interglacial (MIS 5e) is observed. Over this paleosol, the Valdai soil-sediment series (MIS 5d – MIS 2) is located. It includes four interstadial soils, two of them of the Early Valdai (Kukuevo and Streletsk ones), and two, sometimes three, of the Middle Valdai (Aleksandrov, Hydrouzel и Bryansk ones). The OSL date, 127 ± 8 ka BP, (beginning of MIS 5e) was obtained for a sample taken from the bottom of the Ryshkovo soil. The interglacial soil is overlain by the Seym layer formed mainly from destroyed and redeposited horizons of this soil. For the upper part of the Seym layer, OSL dates of 115 ± 7 ka BP and 112 ± 20 ka BP were obtained (MIS 5d). But the process of burial of Ryshkovo soil in the bottom of the paleobalka began at the end of the interglacial after a catastrophic forest fire. Large post-permafrost deformations - pseudomorphosis is confined to Selikhovodvor loess - MIS 4 (65 ± 8 ka BP). Two soils occurring between Seym and Selikhovodvor loesses: Kukuevo and Streletsk - Early Valdai (MIS 5c and MIS 5a). For Mlodat loess which separates those two soils (MIS 5b), OSL dates of 91 ± 1 and 89 ± 7 ka BP were obtained. For paleosols of Middle Valdai (MIS 3), <sup>14</sup>C-dates were obtained: Aleksandrov (53.742 - 2.124 ka cal BP) and Bryansk soils (37.618 ± 0.668 ka cal BP). For Tuskar loess, which separates Alexandrov and Bryansk soils, OSL dates of 50 ± 3 and 51 ± 3 ka BP were obtained. The new stratigraphic scheme of Late Pleistocene agrees with the ideas of researchers from Eastern, Central, and Western Europe , which allows the following correlations. The identified paleosols correspond to the following intervals: Ryshkovo – Eemian interglacial (127-117 ka BP); Kukuevo to Amersfoort + Brørup – Saint-Germain 1 (105-95 ka BP); Streletsk – Odderade to Saint-Germain 2 (about 85-75 ka BP); Aleksandrov to Oerel (56-53 ka BP); Hydrouzel to Moershoofd – Poperinge (44-45 ka BP) and Hengelo (40-38 ka BP); and Bryansk (33-27 ka BP) to Stillfried B, Denekamp or Grand Bois interstadials. The reconstructed Late Pleistocene loess-paleosol sequence has the most similar structure with loess-paleosol sequences of Ukraine, with sequence Dolní Věstonice in Moravia (Czech Republik), Stillfried in Austria and Mainz-Weisenau in the Rhenish area (Germany), and other archives. <strong>This work was supported by RFBR, grant N19-29-05024 mk. </strong></p>

Chapter 4 summarizes the construction, subsistence, and social correlates of Huaca Prieta, a mound site in the lower Chicama Valley on the north coast of Peru, from the earliest evidence of human presence in the Late Pleistocene (ca. 12,500 14C BP) through abandonment at 3,800 14C BP. Marine resources were important throughout the sequence, which saw an early advent of agriculture and increasing population, complexity, and monumentality.
