 The sediments of this formation in "Smiłów Quarry" are mainly fine-grained Sandstones with small over-minerals.Diagonal layers and wave strata appear in them, where there is also traces of root plants with numerous plant remains.Juzuz Karaszewski observed in the "Drzewica Sandstone" vertically preserved plants, and on this basis he derived a possible Dune-related origin of these sediments.
