Upper Permian dykes in southern Scoresby Land, East Greenland

During field work in the Upper Permian of Scoresby Land, a number of thin lamprophyric dykes were found in the area around Revdal (fig. 36). Direct fjeld evidence indicates a Late Permian age for at least some of these dykes. Such dykes are known to occur elsewhere in East Greenland (Haller, 1971, fig. 122), where some are thought to be of Devonian age (Haller, 1971).
