context_page_description: The Blanowice Formation is a geologic formation in Częstochowa, Poland. It is late Pliensbachian-Lowermost Toarcian age. Vertebrate fossils have been uncovered from this formation, including tracks. Along with the Drzewica Formation is part of the Depositional sequence IV-VII of the late lower Jurassic Polish Basin, with the IV showing the presence of local Alluvial deposits, with possible meandriform deposition origin, dominated in Jagodne and Szydłowiec, while delta system occurred through the zone of the modern Budki. Deposits of sequences IV, V, VI and VII make up the Blanowice Formation, being all four sequences are of Pliensbachian age, documented by megaspores. On the upper strata, “sub-coal beds" cover the sequence VII-lower VIII, while the uppermost part of VIII is identified with the Ciechocinek Formation. The Blanowice Formation has been know for decades thanks to the abundant Plant fossils and plant roots, but mostly due to the Blanowice Brown Coals, where the oldes Biomolecules found worldwide have been recovered.
