Facies variation and trace fossil assemblages of the Vardekløft and Olympen Formations of Jameson Land and Scoresby Land, central East Greenland

Abstract

In connection with the systematic mapping programme carried out by the Geological Survey of Greenland in the Scoresby Sund region of central East Greenland during 1968-1972, the Jurassic sediments of Scoresby Land and Jameson Land were mapped and a lithostratigraphical scheme established(Bromley et al., 1970; Surlyk & Birkelund, 1972; Surlyk et al., 1973). Among the established tormations, the Vardekløft Formation and the Olympen Formation ot the Middle and Upper Jurassic showed remarkable variation in thickness and facies within the area studied. In order to get a more detailed picture of this pattern a closer study of a number of selected sections has been carried out (fig. 24).
