Introduction
My research focuses mainly on palynological analysis of Upper Cretaceous, Paleogene and Neogene sediments as well as reconstruction of ancient vegetation and palaeoclimate based on fossil spore-pollen assemblages. I am also interested in freshwater organic-walled algal microfossils (mainly Zygnemataceae and desmids) from Neogene deposits and reconstruction of the palaeoenvironment.

Pterocarya fraxinifolia, native to the southern Caucasus and adjacent areas, has been widely introduced in Europe. In this study, we investigate the following: (1) How did its current distribution form? (2) What are the past, current, and future suitable habitats of P. fraxinifolia? (3) What is the best conservation approach? Ecological niche model...

The paper presents results of a palaeobotanical investigation of the borehole core Komorniki 97/72 from the Ruja lignite deposit, Lower Silesia. In the deposit lignites of three (2nd Lusatian, 2nd A Lubin, and 1st mid-Polish) middle Miocene groups of seams are present. The lignites of the 1st and 2nd groups are important correlation horizons throug...

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-...

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...

The 1st mid-Polish group is the youngest among the main Neogene lignite seams in Poland. Lignites of this group developed in the middle Miocene in almost the whole of Poland, and therefore they are an important correlation horizon throughout much of the Polish Lowlands. A total of 30 palynological samples from the 3-metre thick seam from the Adamów...

The Miocene represents a time in Eurasia when evergreen and thermophilous dominated Paleogene vegetation was replaced by deciduous and temperate plants. Climatically, it is the transition from a greenhouse to an icehouse world, with the middle Miocene Climatic Optimum as the last warm episode of Earth history. Processes of plant evolution, transfor...

The Late Oligocene was a time period of substantial warming of West Antarctica and considerable reduction of the Antarctic ice-sheet that developed and expanded to sea-level during Early Oligocene. This warming event is recorded in the oceanic sediments by a negative shift of the δ 18 O curve and by findings of palynoflora in shallow shelf drilling...

The Zygnemataceae are an extant family of freshwater filamentous green algae which produce acid-resistant zygospores. Palynomorphs of probable zygmatacean affinity occur in sediments of the Carboniferous to Holocene age (van Geel & Grenfell, 1996). These algae reproduce using four types of spores, but only zygospores and probably aplanospores are a...

Project
sedimentological, mineralogical, petrographic, palynological, and geochemical characteristics of the sediments: underlying MPLS-1 (mainly sands), lignite-bearing (mainly lignites of MPLS-1), and overlying MPLS-1 (the so-called “Poznań clays”, mostly muds); determination of the depositional environment (river and mire types), which was related to the deposition of various lithologically rocks such as sands, lignites, and muds; new proposal of depositional and palaeogeographic models for 4 time periods: before ~15.5 Ma (sediments underlying MPLS-1), ~15.5–15 Ma (lignite seam, i.e. MPLS-1), ~15–13.5 Ma (grey clays overlying MPLS-1) and after ~13.5 Ma (“Poznań clays).
Project
The main aim of this project is to determine the changes of depositional environments in central Poland during the Mid-Miocene, that is, ca. 15±1.5 Ma. These changes will be presented in the context of climatic fluctuations and intense vertical movements of the Carpathian-Alpine orogen as well as slight lowering of the Polish Lowlands area. On the basis of preliminary studies, we believe that all lithologically varied the Mid-Miocene sediments in central Poland (sands, lignites and overlying muds, so-called "Poznań clays") are genetically related to different types of fluvial environment. Therefore, determining the river type (braided, meandering, anastomosing), in which environments were formed deposits of various lithologically (sands, lignites, muds) seems to be a very important part of this project.
Project
The main project objective will be to determine whether the observed differences in Campanian-Maastrichtian rock composition (expressed in literature by different lithological terms) are an effect of paleoecological perturbation during deposition (different bathymetry, nutrient influx and coccolith blossoms, rate of deposition) or of early and late diagenetic process (mechanical and chemical compaction, neomorphism, recrystallization and cementation) after the sediment disposition. Good understanding of the Late Cretaceous carbonate rocks formation and its later diagenetic transformation are crucial for further paleoecological and paleogeographical interpretations and global scale correlations (based on chemostratigraphy). This integrated multidisciplinary approach aims to understand how the sedimentology-diagenesis-shaped microtexture controls the properties of studied rocks. The matrix microtexture combined with identification of its main constituents are the key link between rock depositional/diagenetic history. The analysis will concentrate on the composition and origin of main constituents of Late Cretaceous rocks: bioclasts, micrite, quartz/biogenic silica and clay minerals. Integrated multidisciplinary studies will be focused on thin section analysis (under optical microscope), SEM-EDS analysis, XRD analysis, CL analysis, and stable isotope analysis (δ13C, δ18O).
