Sedimentological observations in middle and late Triassic rocks, Jameson Land Basin, central East Greenland

Abstract

The middleand late Triassic rocks of Jameson Land and the nearby part ofthe Scoresby Land area in central East Greenland (fig. 33) were studied during the 1975 field season as part of a 2½-year joint GGU-University of Copenhagen project. The work entailed the detailed measurement of several sedimentological sections. Emphasis was laid on the primary sedimentary structures and a large number ofpalaeocurrent measurements were carried out. The ultimate goal of this approach is to understand the palaeogeographical evolution ofthe sedimentary basin during middle and late Triassic time. This note is a preliminary account and delineates only the sedimentary history ofthe basin in very broad terms.
