ABSTRACT The morphology of the Mazury Lake District (north-eastern Poland) dates from 24-19 ka (main stadial of the youngest Vistulian glaciation). During this last glacial maximum (MIS 2) a belt with lacustrine basins was formed when the ice sheet retreated at the end of the Pomeranian phase. The ice-sheet retreat is morphologically also expressed by the occurrence of end moraines. The study area is situated in the Skaliska Basin, in the northern part of the Lake District (near the Polish/ Russian border), at the periphery of zone with end moraines. Originally the basin was an ice-dammed depression filled with melt water; the water flowed out into the developing Pregoła valley when the ice retreated and did no longer dam off the depression. The basin, which is surrounded by hill-shaped moraines, is filled now with Late Glacial and Holocene glaciolacustrine sediments. The organic sediments of the basin record the history of the Late Glacial and Holocene climatic changes in this region.

New radiocarbon dates obtained from Late Pleistocene and Holocene deposits of the southern, eastern, and northern shores of Lake Baikal in 1995–2001 are presented, and the most important results of paleoenvironmental studies based on C data are discussed. The following paleogeographic events were verified with the help of C dating: 1) first Late Pleistocene glaciation (Early Zyryan); 2) Middle Zyryan interstadial; 3) loess formation during the Late Zyryan (Sartan) deglaciation; 4) warm and cold events in the Late Glacial; and 5) vegetation changes and forest successions during the Late Glacial and Holocene.

This article is devoted to a review of the data on the chronology of the occupation of the Eastern Pamirs high-lands and the paleoecological reconstructions. At this moment it is known that there are two main episodes of the settlement of the region in the Final Pleistocene – Middle Holocene: 12–8 ka BP. (the main archaeological sites are the Istyk cave and the Kurteke grotto) and 8–6 thousand years ago (Oshkhona, Shakhty, Istykskaya cave, Kurteke). The review shows that these episodes coincide with the periods of the most favorable paleoclimatic conditions. The climate of the region in general is characterized as arid desert, with a predominance of open spaces of desert-steppe and desert appearance. The time intervals about 15–13 thousand years ago and about 9–8 thousand years ago are characterized with a transition from xerophilic groups to more mesophilic, which indicates a humidification of the climate during these periods. The researchers note that these climatic changes are likely to be pan-regional. The revealed cyclicality of climate changes in the Eastern Pamir region is comparable to archaeological data: the time intervals in when an increase in the climate humidity of the region is noted are similar to the intervals in when, according to archaeological data, the region was populated. Further paleoecological reconstructions of the Eastern Pamirs will reveal the connection between the cyclicality of climatic changes in the region and human settlement in its territory.

Abstract In the field seasons of 1990 to 2008 the Combined Prehistoric Expedition conducted an extensive archaeological, archaeozoological, archaeobotanical and geomorphological field work at more than a hundred sites in the Nabta, Kiseiba, El Kortain, Gebal El Beid, Gebel Ramlah and Berget El Sheb Areas, South Western Desert of Egypt. The research has helped to develop a long chronological sequence of Late Glacial and Holocene climatic changes in the region. The climatic sequence has been supported by more than 300 14C and OSL assays that permitted to place most of the climatic events in a firm chronological frame
