Popis: | An integrated magneto- and biostratigraphic study of the Jurassic-Cretaceous (J-K) boundary section at Kurovice, Czech Republic was carried out. The acquired paleomagnetic data showed dual polarity characteristic remanent magnetization (ChRM) with counter-clockwise rotation direction. Rock magnetic data indicated magnetite as the principal carrier of remanent magnetization as well as presence of e.g. hematite and goethite. Magnetozones from M21n up to M17r were identified and dated as early Tithonian (dinoflagellate Semiradiata and nannofossil NJT15b zones) to late early Berriasian (Calpionella elliptica and nannofossil NK-1 (sub)zones). |
