The lithology and stratigraphy of the Jurassic sequence in the Danish Subbasin is described from 5 wells situated in the central region of the Danish Subbasin. The chronostratigraphic subdivision of the Lower Jurassic Fjerritslev Formation is discussed and modified in the light of new biostratigraphical and lithostratigraphical data from the five well sections. The Jurassic lithostratigraphic subdivision is amended. The F-Ia, F-lb, F-II, F-III, and F-IV members of the Fjerritslev Formation are redescribed and defined in relation to the reference section in the Hyllebjerg-1 well. The Haldager and Bream Formations are abandoned. The Haldager Sand, Flyvbjerg, Borglum, and Frederikshavn Members are elevated to the rank of formations.
