Miospore assemblages from the Łobżonka Formation from three boreholes situated in the Laska–Czaplinek zone in Western Pomerania represent the lower part of the Lycospora pusilla (Pu) Biozone established for that area. An assemblage from one sample may represent this zone or the preceding Prolycospora claytonii (Cl) Biozone. This indicates that the sequences investigated may be attributed to the lower Viséan, and that the lower part of one of these may represent the uppermost Tournaisian. It is suggested that the part of the Łobżonka Formation studied is the lateral equivalent of the lower (but not the lowermost) part of the Drzewiany Formation of the Koszalin–Wierzchowo zone.

The Early Carboniferous age of the flysch succession in the Moravian-Silesian zone has been based principally on lithological correlations with the stratotype goniatite-bearing section. Its uppermost part-the Kyjovice Formation in the region of Toszek (Poland)-has been studied palynologically for the first time. Miospore assemblages of the upper part of the Western European nitidus-carnosus (NC) miospore Zone of the early Serpukhovian have been distinguished. This agrees well with a general stratigraphic range of the Kyjovice Formation within the Go-E1a goniatite zones.

W badawczo-poszukiwawczym otworze Tarnawa 1, zlokalizowanym około 25 km na wschód od Myślenic, przeprowadzono badania sporowe utworów klastycznych karbonu w interwale głębokości 4407,0 –4585,0 m. Dotyczyły one wyłącznie osadów płonych. Stwierdzono w nich asocjacje o typie mieszanym, skomponowane z taksonów charakterystycznych zarówno dla górnowizeńskich, jak i dolnonamurskich zespołów sporowych, w większości reprezentujących mikroflorę typową dla zony sporowej NC (nitidus-carnosus), odpowiadającej najwyższej części brytyjskiego piętra brigant (= zona goniatytowa P2) i piętru pendlej (= zona goniatytowa E1) w schemacie Claytona i in. (1977). Istotny udział w spektrum stanowiły również taksony zon sporowych asbu: TC (tessellatus-clavata) i NM (nigra–marginatus) — Perotrillites tessellatus, Raistrika nigra, Triquitrites marginatus oraz brigantu: VF (vetustus–fracta) — Potoniespores aff. delicatus Playford, cf. Potoniespores delicatus sensu Playford, Tripartites distinctus i Murospora cf. partenopia. Najmłodsze oznaczone gatunki sporomorf sugerują jednak arnsberski wiek asocjacji, poprzez związek z zoną sporową TK (triangulus–knoxi) (Clayton i in., 1977).

Deep, test-exploratory borehole Tarnawa 1 from the hydrocarbons penetrating zone is situated 25 km east of Myślenice, between Wianiowa IG 1 borehole in the West and Rajbrot 2 in the East (Carpathians, Poland). Coal-bearing clastic sediments of the Lower Carboniferous have been ascertained there only on lithological and geophysical data (Daran et al., 1997) and originally biostratigraphically unconfirmed. Mixed spore associations have been distinguished in the depth interval between 4585,00 m and 4407,00 m. Composed principally of Brigantian and Pendlcian taxa they also contained species characteristic for Asbian-Brigantian standard spore zones: TC (tessellatus-clavata) represented by Perolrillites tessellatus (Staplin) Neville, Potoniesporcs aff. delicalns Playford, Poloniespores delicatus sensu Playford, NM (nigra-marginatus) characterized by Ra-istrickia nigra Love, Triquitrites marginatus Hoffmeister, Staplin, Molloy, Tripartitcs distinctus Williams and VF (vetustus-fracla), as well as the elements of microflora typical for the Lower Namurian: Punctatisporites sinuatus (Artüz) Neves, cf. Crassispora kosankei? (Potonié et Kremp) Smith et Butterworth, cf. Florinites sp.?, Mooreisporites fustis Neves, Moreisporites trigallenis Neves (G. Clayton ct al., 1977; R. Neves, 1958, 1961). Index taxa: Bellispores nitidus (Horst) Sullivan and Reticulatisporites carnosus (Knox) Neves made possible their correlation with Brigantian-Pendleian standard spore zone NC (nitidus-carnosus) of the unified palynostratigraphic scheme of the Carboniferous for the Western Europe, whereas the abundance of Mooreisporites spp. might have suggested their correlation with younger Amsbergian spore zone TK (trianguhis-knoxi) (G. Clayton et al., 1977).
