Bogate spektrum jednoworkowych ziarn pyłku, przeważających nad formami dwuworkowymi, otrzymano z próbki pochodzącej z głębokości 4327,0–4335,0 m. Wiek próbki na podstawie mikroflory określono na dolny perm. Przynależnośc botaniczna całego zespołu wskazuje na dominację roślin szpilkowych.

Palinological research has been carried out on the sample from the depth of 4327.0-4335.0 m. After chemical maceration using first 36% solution of hydrochloric acid and then 45% solution of hydrofluoric acid, the macerat became decanted and sieved using nylon riddle of the diameter of 10μ. Such a condensed macerat was used to prepare standard microscope preparations which were then preserved using Petropoxy glue. This way, microflora associations were protected from drying. The preperations were subjected to microscopic planimetric analysis in a transmitted light. To obtain larger amount of palinological material, chemical maceration was carried out twice. Planimetric palinological analysis revealed the presence of a rich spectrum of the following monosaccatae pollen grains: Florinites luberae, F. grandis, F. minutus, F. pwnicosus, F. mediapudens, Potonieisporites novicus, P. rimosus, P. negleclus, P. grandis, P. permollis, P. lemniscatus, P. concinus, Wilsonites cf. vesicatus, Cordailina uralensis, Plicatipollenitesgondwanensis and Crucisaccites lalistilcatus. Among the bisaccatae pollen grains, the following spe-cics were determined: Gardenasporites pinnatus. Crustaesporites globosus, Vesicaspora potoniei, Pseudopodocarpus expresus and Jugasporites delasaucei. All these examples of microflora clearly indicate Lower Permian age. It significantly differs from the Carboniferous association determined below. The botanical attachment of the microflora studied confirms the domination of the conifers which replaced Carboniferous hygrophilous flora into xerophilous one at the turn of Carboniferous and Permian. The appearance of first bisaccatae pollen grains which predominate in Upper Permian (eg. Jugasporites delasaucei) indicates a permanent trend of dry climate changes into almost semidesertic climate of Upper Permian. The determined association of microflora may be compared with an association known from Lower Permian - Autunian of the Sudetic Mountains and Pre-Sudetic monocline (Dybova-Jachowicz, 1995) and also from Asselian of Donicck Basin, Ukraine (Inosova et al-, 1976). Photographic documentation was made by M. Jachowicz using Olympus BX50 microscope with 750x magnitude.
