These sediments are dated by the 14C method in the case of organic remains, by counting annual laminations in lacustrine facies, and by dendrochronological method in the case of fluvial sediments.The existence of well dated profiles enables to reconstruct various climatic parameters like amplitudes of seasonal temperatures, types and frequency of extreme rainfalls and floods and, finally, to distinguish rare rapid changes and most frequent gradual ones. This reconstruction is based on the analogous effects of various types of present-day rainfalls.The current authors present a critical review of existing chronostratigraphic divisions starting from simple millennial division by Mangerud based on Scandinavian palynological stratigraphy of peat-bogs and S...

Vegetation on the Wawel Hill, Cracow (Poland) in the early Middle Ages based on the fragmentary pollen record. Archaeological research excavation in the basement of building No. 9. Sprawozdania Archeologiczne 73/2, 287-311. Palynological research was carried out on layers archaeologically dated to the early Middle Ages in the basement of the former Austrian hospital at Wawel. The interpretation was based on the sparse number of sporomorphs presented in the samples, not on the percentages. At the end of the first millennium, on the Wawel Hill and in its vicinity, an open landscape developed with a mosaic of plant communities, including ruderal ones, fields, pastures, and meadows, as well as bushes and forests. Sporomorphs reached the analysed area partially naturally, with pollen rain from plants growing at sites in the Wawel Castle itself and from the immediate or further surroundings of the Wawel Hill. Some sporomorphs reached ...

The deposit thickness (about 3.5 m) has permitted high resolution pollen, peat (including macrofossils) and lithology analyses. Vegetational and palaeoenvironmental changes in this part of the Roztocze were recorded in pollen spectra and organic deposits. Palynological evidence shows the typical Neoholocene succession, which corresponds with the phenomena described from central Europe: from mixed deciduous forests at the decline of the climatic optimum, through hornbeam- and beech-dominated forests to pine forests. Peat accumulation in the Kobyle Jezioro peat-bog started during increased climatic humidity at the beginning of the Subboreal, and originally a fen peat was formed. Raised bog peat layers make up the uppermost 80 cm of the deposit. Within the fen deposits can be found layers of transitional peat, indicating short-term episodes of water deficiency in the early Subboreal phase (short-term climatic dryness) and towards its end (drainage of the bog resulting from the lowering of the groundwater table in the source area of the Tanew River). The growth of the raised bog started at the beginning of the climate deterioration in the Little Ice Age, and the unstable climatic conditions are reflected in the numerous periodical mineral (aeolian) material supplies in the developing ombrogenic bog. The accumulation of the younger section of transitional and raised peats during the Little Ice Age reflects the local hydrological changes in the source area of the Tanew River.

This is especially so if the goal is to distinguish between two relatively close events. Proposed herein is a calculator, or alternatively a graph, which enables reading of the difference between two radiocarbon ages corresponding to their expected calendar ages. The result may surprise the less experienced 14C users. Such a calculation also indicates the time periods with high or low potential for application of the wiggle-matching method.

Floors of these basins, carved in soft shale-sandstone Krosno Beds, are covered with channel fluvial deposits and oxbow-lake sediments with lake chalk and peat accumulated in the Late Vistulian and Holocene. Since the early Atlantic Phase (ca 8,400–7,900 BP) the apparent acceleration of overbank (flood) deposition intermitting the peat accumulation is observed. The plant succession includes the Late Glacial (pre-Allerød, Allerød and Younger Dryas) with coniferous park forests, through mixed deciduous forests of the Holocene with elm, hazel, oak and lime as well as spruce-elm forests with alder in wetlands, up to present-day hornbeam forests (Tilio-Carpinetum of various types) and extra-zonal Carpathian beech forests (Dentario-GlandulosaeFagetum). Abies alba (fir) is frequent in both these association types. Firs...

In con nec tion with the West Carpathian pro ject the au thors have de vel oped the idea of graph i cally pre sent ing on the map a rate of change of the pol len per cent age. Such a map is based on the data from two time ho ri zons. The pre ci sion of such a type of map, which shows the %/change/100 yrs, and in which the value can be neg a tive as well as pos i tive, is lower that of a typ i cal isopollen map. How ever, this type of map gives a di rect in sight into changes in the plant cover, which are re lated to cli mate change.

This is expressed by a strong, rapid cooling in the middle part of the pine phase ending this interglacial (E7 regional pollen assemblage zone), and then a re-warming at the very end of this phase, immediately before the transition to the glacial conditions of the last glaciation (Vistulian, Weichselian, MIS 5d). We have characterized the regional distributionof these climatic fluctuations in Poland on the basis of isopollen maps prepared for the Eemian Interglacial based on palynological data from 31 Polish pollen profiles. These maps show unequivocally that the intra-interglacial cooling at the end of the Eemian Interglacial was a transregional phenomenon, which was reflected very clearly by a temporary openness of vegetation across the whole of Poland. It was associated with a distinct decrease in pine forest areas and an increase in birch forests and open communities of cold steppe type with a domination of Artemisia. The pronounced climate and environment instability during the last phase of the Eemian Interglacial may be consistent with it being a natural phenomenon, characteristic of transitional stages. Taking into consideration the currently observed global warming, coinciding with a natural cooling trend, the study of such transitional stages is important for understanding the underlying processes of climate change.
