The Jurassic of Denmark and adjacent areas occurs mostly in the subsurface and research has thus focussed on the wealth of borehole and reflection seismic data resulting from over thirty years of hydrocarbon exploration. The Jurassic of East Greenland, in contrast, is exposed in spectacular cliffs along fjords and mountainsides and has come to be regarded as a unique field laboratory, particularly amongst those working on the Norwegian shelf--the conjugate margin of East Greenland. This bulletin presents the results of a period of intensive research into the Jurassic in the late 1980s and 1990s. Following detailed chronostratigraphic and biostratigraphic reviews of the Jurassic of Northwest Europe, the successions of Denmark and East Greenland are subjected to a range of stratigraphic, sedimentological, structural and geochemical studies that together provide the basis for a detailed comparison of the Jurassic evolution of the East Greenland and Danish sedimentary basins.
