Blanowice Formation
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 (Horstisporites). On the upper strata, “sub-coal beds" cover the sequence VII-lower VIII (Pliensbachian-Toarcian transition), while the uppermost part of VIII is identified with the Ciechocinek Formation. The "Blanowice Formation" has been known for decades thanks to the abundant Plant fossils and plant roots, but mostly due to the "Blanowice Brown Coals", where the oldest Biomolecules found worldwide have been recovered. The Mrzygłód mine dinocyst assemblage is taxonomically undiversified, containing specimens that are good age indicators al lowing relatively precise suggestion of its age. "Luehndea spinosa", with a single recovered specimen spans between the Late Pliensbachian (Margaritaus) to the Lowermost Toarcian (Tenuicostatum). Other ocal dinocysts such as "Mendicodinium" range Late Pliensbachian–Aalenian, a wider stratigraphic range. The lower part of the formation is coeval in age with the Gielniów Formation and Drzewica Formation (Southern and central Poland), Lobez Formation and Komorowo Formation (Pomerania), Olsztyn Formation (Baltic German-Polish transition), the lower part of the Rydeback Member of the Rya Formation (Southern Sweden), lower Fjerritslev or Gassum Formation (Danish Basin), lower and middle Bagå Formation (Bornholm), Neringa Formation (Lithuania). The Upper part is coeval with the lowermost upper Rydeback Member, upper Gassum Formation and lower Lava Formation (Lithuania).
