Palynological analysis of the Tomisławice opencast mine deposits has allowed reconstruction of the plant communities and investigation of the evolution of sedimentary environments at various stages of lignite-forming marsh development, recorded in the composition of pollen assemblages from deposits of the 1st Mid-Polish lignite seam (MPLS-1). Rich...

On overview of over a hundred years of history of Polish palaeobotanical research on the Paleogene and Neogene (formerly Tertiary) is provided. Profiles of the researchers who laid the foundations for the development of paleofloristic research are presented. In particular, we describe individuals who have made significant research contributions, in...

A b s t r a c t. In the northern Lublin region, the Eocene amber-bearing association has been recognized. It is a group of clastic deposits in which amber crumbs are scattered, and the characteristic feature of the association is the content of glauconite. The sedimentological and lithofacies studies allowed determining the conditions necessary for...

Many geological problems have not been convincingly explained so far and are debatable, for instance the origin and changes of the Neogene depositional environments in central Poland. Therefore, these changes have been reconstructed in terms of global to local tectonic and climatic fluctuations. The examined Neogene deposits are divided into a sub-...

Palynological research was performed on the first Mid-Polish lignite seam (MPLS-1) at the Jóźwin IIB open-cast mine. The extremely rich pollen assemblages allowed investigation of the development of phytogenic sedimentation and the succession of plant communities. The vegetation cover, representing peat accumulation and adjacent areas, was reconstr...

We reconstruct palaeoenvironmental conditions during the formation of the first Mid-Polish Lignite Seam (MPLS-1) of the Konin Basin of central Poland, which is of mid-Miocene age. In terms of macropetrography, the MPLS-1 comprises different lithotype associations, predominantly xylodetritic lignite, and represents the peat deposits of mires most li...

Lithological and palynological studies of Paleogene siliciclastic deposits from the Yantarny P-1 borehole located on the western coast of the Sambian Peninsula (Kaliningrad region, Russia) show that the succession is characterized by numerous sedimentary discontinuities related to lithification horizons and erosional surfaces. Sedimentary gaps are...

On the area of occurrence of rich lignite deposits in Western Poland, Brandenburg and Saxony, in the glaciotectonic deformation zone of the Muskau Arch, both Quaternary and the younger part of the Neogene sediments were extensively deformed. During this process, many fragments of some lignite seams have been uplifted to the soil surface in form of...

The latest edition of the methodology for the preparation of the Detailed Geological Map of Poland in the scale 1:50,000 (DGMP 1:50,000). This Map is elaborated in Polish on the base of geological mapping, especially drilled boreholes to subQuaternary basement as well as geological and geophysical surveys and laboratory studies. The whole edition c...

Pollen analysis has revealed the presence of the edmundi morphotype in the Paleogene and Neogene sediments of Central Europe. Its species, characterized by different morphologies, are mainly assigned to two families of extant plants-the Araliaceae and the Mastixiaceae-and compared to pollen of some genera (Diplopanax and Mastixia from the Mastixiac...

Brown coal and overlying sand strata from the Łukowa-4 borehole, located in the northeastern sector of the Carpathian Foredeep in Poland, were studied for palynology. These strata are underlain by Upper Eocene sands, and covered by Middle Miocene rocks. Coal beds yielded infrequent sporomorphs and freshwater algae Botryococcus. The presence of the...

The accumulation of large amounts of phytogenic matter, leading to the formation of lignite deposits of economic importance, has been determined by two groups of external factors: (a) climatic factors determining the indispensable production of organic matter and (b) geological factors allowing preservation of this matter in the sediment and its di...

Badawczy otwór wiertniczy w Wysokiej Wsi, zlokalizowany w centrum Wzgórz Dylewskich (NE Polska), osiągnął głębokość prawie 490 m, z czego na ponad 400m przewiercono utwory paleogenu i neogenu. W wyniku badań palinologicznych 47 próbek wyróżniono 13 zespołów palinomorf (sporomorfy, fitoplankton i zoomorfy) i datowano osady. Stwierdzono dwu- i trzykr...

The aim of the study was to identify and examine the Cenozoic strata in the southeastern margin of the Zittau Basin (Ohf e Rift) at the crossborder of Poland, Czech Republic and Germany, and to determine the age of the sedimentary and volcanic rocks related to synsedimentary volcanic events. The Opolno Zdrój PIG-1 borehole, located near the village...

The reported study focused on a complex analysis of Paleogene-Neogene section located at Łęczyce near Lębork (Eastern Pomerania). The lower part of the section is represented by Lower Oligocene to Miocene deposits, drilled by the Łęczyce-Tr well to the depth of 110 m. Its upper part consists of the Late Neogene succession exposed in the slope of th...

The Wysoka Wies̈ borehole located in the center of Dylewskie Hills (NE Poland) reached a depth of almost 490 metres, with more than 400 metres of the Paleogene and the Neogene deposits. Palynological studies were designed to determine whether this huge Paleogene and Neogene sedimentary complex is located in situ or it has been glacitectonically red...

Pollen, phytoplankton and microfauna from the Palaeogene and Neogene of two boreholes in NE Poland have been studied. Borehole Klucznik 1 is located in the Warmia area, and borehole Saplaty 3 borehole in the Mazury area. The oldest palynomorph assemblage comes from the Klucznik sediments; it consists of phytoplankton from the Early Palaeocene (Dani...

A continual record of Eggenburgian to Late Badenian deposition, mostly in non-marine environments during the Early Miocene and in marine settings during the Middle Miocene time periods, was studied in the Woszczyce IG1 borehole (Zawada Basin, the Upper Silesia segment of the Carpathian Foreland Basin). In addition to the earlier-described Early Mio...

Part 1. Detailed phytoplankton investigations were performed on the Paleogene deposits from the Pomeranian Lakeland. Phytoplankton assemblages were identified and described in 11 boreholes. 136 phytoplankton taxa have been identified. The taxa belong to the classes Dinoflagellata, Prasinophyta, Chlorophyta and to the Acritarcha group. On the basis...

Tertiary deposits in the Middle Vistula River valley have been palynologically studied. Sediments were investigated during research for several sheets (Deblin, Kozienice, and Pulawy) of the Detailed Geological Map of Poland in 1: 50,000 scale -. Seven palynological assemblages were recognized, containing Upper Paleocene, Middle and Upper Eocene, Lo...

Cretaceous /Tertiary boundary deposits from Kamienny Dól outcrop has been palynological studied. Among palynomorphs the main role plays phytoplankton - mostly Dinoflagellata cysts. Pollen grains of vascular plants. Bryophyta spores and hyphae were met sporadically. Single palynoclasts were the black, not transparent, probably woods debris. Analysis...

Detailed palynological analysis of palaeotropical and arctotertiary geofloristic elements throughout the Neogene has resulted in a general reconstruction of the Central European vegetation. A careful vegetational representation has been established for crucial floristic episodes i.e. Eggenburgian, Badenian and Pontian. These pictures exhibit a diff...
