Coal-bearing conglomerates occur in the Menilite Formation of the Silesian Unit, outcropped in the village of Kobielnik. Coal particles are angular and differ in size (2 mm-6 cm). The examined coal shows rather predominance of vitrinite (collotelinite, collodetrinite, vitrodetrinite). However, the presence of inertinite (fusinite, semifusinite and inertodetrinite with rather accessory funginite and secretinite) is also significant. However, liptinite (sporinite, cutinite and resinite) also indicates its presence in the maceral composition. The results of both coal petrographic and palynologcal analyses were conducted with the intention of applying them to reconstruct environments of coalformation. Palynological studies revealed palynofacies consisting mainly of black palynoclasts ofrectangle or oval shape. Miospores are abundant and various in colour-from yellow to dark brown. The miospore assemblage is dominated by Lycospora and several other Carboniferous genera occur there. The presence of Radiizonates aligerens (Knox) Staplin, Jansonius, the guide species to the lower part of the Westphalian A (Langsettian) indicate that at least part of the coal pieces come from this part of the Pennsylvanian. The age position of the whole miospore assemblage should be determined as the Late Bashkirian-Moscovian (Westphalian). Additionaly, some older miospores, usually dark in colour, were found in this assemblage and they are considered as reworked.
