Biostratigraphical correlation of spore and conodont zonations within Givetian and ?Frasnian of the Lublin area (SE Poland)

Givetian and ?Frasnian spores associated with conodont elements occur in two boreholes in the Lublin area allowing definition of the stratigraphical relationship of the first appearance or last occurrence of selected spore species and form features to the conodont division. Spore data from a section lacking conodonts but correlatable on lithostratigraphy with the conodont bearing one are also considered. The spore zonal scheme for Western Pomerania is correlated with the conodont zonation. The first occurrence of Chelinospora concinna (base of the Ex 2 Subbiozone) and Kraeuselisporites spinutissimus are probably within the range of rhenanus/varcus to ansatus Biozones, not above the ansatus Biozone. The first occurrence of Samarisporites triangulatus (base of the Ex 3 Subbiozone) is in the ansatus Biozone. The disappearance of Aneurospora extensa (base of the Aur Biozone) is within the range of ansatus to hermanni Biozones. The species Corystisporites pomeranius and multifurcate-spined spores appear in the falsiovalis Biozone, probably in the Upper falsiovalis Biozone. The first occurrence of Tholisporites densus (base of the Den Biozone) is somewhat higher but still in the same biozone.
