Opis:
The malacofauna of the palaeolake deposits at Szymanowo (eastern Poland) was investigated. It represents the younger part of the climatic optimum of the Mazovian (Holsteinian) Interglacial (~MIS 11) and possibly the postoptimal period. The mollusc assemblage is composed of both standing and running water species, mostly connected with temperate climate. The presence of biostratigraphical indicators of the Mazovian, Viviparus diluvianus (Kunth, 1865), Lithoglyphus jahni Urbański, 1975 and Pisidium clessini Neumayr, 1875, is noteworthy. Variability in the structure and composition of the assemblage enables palaeoecological reconstruction. Changes in the water-level, vegetation and energy conditions are inferred from the malacological succession. Three stages of the lake development were distinguished. The first one is connected with deeper conditions and predominance of V. diluvianus and L. jahni. The second one, dominated by Bithynia tentaculata (Linnaeus, 1758), records a fall of the water-level and the growth of aquatic plants, evidenced by high frequencies of Valvata cristata Müller, 1774 and Acroloxus lacustris (Linnaeus, 1758). The third stage corresponds to another rise of the water-level and an increase in V. diluvianus, L. jahni, Valvata piscinalis Müller, 1774 and Pisidium henslowanum (Sheppard, 1823), which evidence some higher energy conditions.

Opis:
Eastern Poland is a region, where a lot of sites with detailed palynological records of the Mazovian (Holsteinian) Interglacial are located. The pollen succession of this interglacial in Eastern Poland has specific features: high proportions of Pterocarya pollen, the occurrence of Parrotia pollen and a distinct share of pollen of other exotic taxa, among others: Juglans, Ilex, Celtis, Buxus and Vitis. Palynological studies reveal variability proportions of Taxus in the Ma IV Taxus-Picea-Alnus zone. The presence of intra-interglacial cooling is distinct in sediments of this age.

Opis:
Gajec [Rze-1] borehole was drilled for needs of detailed geological mapping of Poland at the scale 1 : 50 000 (sheet Rzepin ). A deep tunnel valley was recognized in this borehole. It was eroded to 120 m below a see level in the Lower Miocene sediments. The tunnel was filled with 85 m thick series of sands, mud and dusty till deposited during the San Glaciation [the Elsterian Glaciation]. The sediments from the depth interval of 67,9 m - 57,1 m have been examined by palinological analysis. The data obtained indicate that the pollen succession from the Gajec section has features characteristic of the Mazovian [Holsteinian] pollen succession. These features are the high proportion of coniferous trees [Pinus, Picea, Taxus, Abies], and the association of Alnus with Picea and Carpinus with Abies, Quercus and Corylus as well the most abundant thermophilous elements. Warmth-demanding taxa are represented by pollen of Pterocarya, Celtis, Juglans, Buxus, Ilex aquifolium and Vitis.

Opis:
Lake sediments of the Mazovian Interglacial were found in boreholes Kasyldów and Wola Okrzejska 48, and deposits of the Eemian Interglacial were discovered in Wola Okrzejska 49 and Szczepaniec bore-holes. The pollen succession recorded in the lacustrine sediments in the pro-files Kasyldów and Wola Okrzejska 48 is characteristic for the Mazovian Interglacial, and those from the profiles Wola Okrzejska 49 and Szczepaniec typical for the Eemian Interglacial. The biogenic sediments in the Kasyldów and Wola Okrzejska (48) were accumulated in lakes, formed after meltdown of the Sanian 2 (Wilgian) ice-sheet. These sites are located within the Mazovian Lakeland, in the south-east of the Żelechów Upland. The glacial horizon of the Sanian 2 (Wilgian) Glaciation occurs under Mazovian sediments. The fluvioglacial deposits of the Wartanian Glaciation cover the lacustrine sediments. The Eemian sites at Wola Okrzejska 49 and Szczepaniec are located in the Okrzejka River valley, which was formed after the Wartanian Glaciation. The silts of the Wartanian Glaciation occur below Eemian deposits. The sands of the Vistulian Glaciation and peats of the Holocene cover the lacustine deposits of the Eemian Interglacial. These sites are important for stratigraphy of sediments, which fill the Okrzejka, Wilga and Mała Bystrzyca valleys.

Opis:
The paper shows results of pollen analysis of organic sediments from the site Malice (M1). The diagram includes 11 local pollen zones representing Mazovian Interglacial. Forest landscape in the vicinity of the site has changed together with the climate amelioration. In the beginning of the interglacial, birch and pine forests predominated in this area. Later, they were replaced by alder, spruce and yew communities, and next by multispecies deciduous forests and fir woods. Warm and humid climate of this interglacial is indicated for instance by high percentage of Taxus pollen (49%). According to Janczyk-Kopikowa, 1991 at the beginning of the pollen period III the pollen curves show that an intrainterglacial climate cooling might have taken place what has also been recorded in many pollen diagrams of this interglacial in Poland. Pollen succession from Malice, apart from features characteristic for the succession of Mazovian Interglacial, also shows many local features caused by differentiation of habitats, and various hydrological and microclimatic conditions. Similar features are also revealed from the succession at the site Konieczki located nearby. Despite the fact that the influence of oceanic climate in Mazovian Interglacial reached farther eastwards than it is now, the forest landscape of Poland was also regionally differentiated, although not as distinctly as it is today.

Opis:
The paper presents results of pollen analysis of organic sediments from the site Katowice 2. Six local pollen assemblage zones identified in the section represent the youngest part of Mazovian Interglacial. The pollen spectra of the basal part of the section display some changes indicative of intra-interglacial cooling, well recorded in many profiles of this interglacial in Poland. The forest landscape was subsequently dominated by hornbeam-fir communities which were replaced later by those of pine forests. In turn, taxa of thermophilous aquatic plants, represented by pollen Trapa and microsporangia Azolla filiculoides and Salvinia evidence of lacustrine environment. The results of pollen analysis of sediments from the Katowice site and those hitherto obtained from some other localities in western and central part of the Polish Uplands (Malice, Raków, Wielki Bór, Konieczki i Białe Ługi) became the basis for distinguishing seven regional pollen zones for this area. As compared to pollen succession from Podlasie and eastern Poland, the most significant differences concern the course of pollen curves of Carpinus and Abies and the sequence of their pollen culmination.
