The Blanowice Beds are distributed in area between Częstochowa, Dębnik, Siewierz and Olkusz in the Silesian - Cracow Monocline.
The coals were mined there in the years 1818-1959.
The major plant bearing strata is exposed at Kierszuła near Poręba, where a identified spore-pollen assemblage comprises higher cryptogamic plants (Bryopsida, Selaginellopsida, Sphenopsida, Lycopsida, Pteropsida) and the gymnospermous (Pteridospermopsida, Cycadopsida, Bennettitales, Ginkgoaceae, Coniferopsida).
The Pollen of coniferous plants has been seen as connected with the Cheirolepidiaceae group, on an assemblage of herbaceous peat-bog vegetation, characterized by predominance of ferns, was most probably the parent material for that variety of coals.
The presence of fairly thick laminae of Vitrain in the Kierszuła middle layers indicates some phases with share of forest assemblage marked in area of contemporary peat-bog.
