Palynological samples from the Zaręby Beds (lower Carboniferous, Holy Cross Mountains) were investigated for palynostratigraphy and palynofacies. Samples, obtained from the Jabłonna IG 1 drill core (21 samples) and the Kowala Quarry (46 samples), allowed determinations of age, ranging from the HD (Cristatisporites hibernicus–Claytonispora disticta) miospore zones in the Kowala Quarry section, to the PC (Spelaeotriletes pretiosus–Raistrickia clavata) Miospore Zone in the Jabłonna section, which corresponds to middle and late Tournaisian. This confirmed the diachronism of these sediments. Land microflora and plant remains predominated over marine phytoplankton. The sections are diachronous; the palynofacies record is rather uniform at both sites, with a small difference in age between the investigated areas. The palynofacies study reveals the deposition close to the source area for the land material. Moreover, the presence of amorphous organic matter, obtained from black shales and cherts, suggests a relatively deep and anaerobic sea bottom conditions.
