Abstract
Radiocarbon dates have been made on material from nine areas in northern Greenland (fig. 40). The results are given in the compilation of C14 dates (see Weidick, this report). The dates from area 5 have been given earlier (Weidick, 1977b). Comments on their significance are given below.
Highlights
The Holocene marine inundation in Olrik Fjord reached 45±5 m above sea level and modified the interglacial sediment locally; a shell sample previously dated from the eastern flan k of eastern Kugssuaq delta in Olrik Fjord (GGU 166125, 18 990±280 B.P., Weidick, 1976a) is from a site approximately 14 km east of the sites of GGU 226427 A & B)
Wood of interglacial age from Wa hington Land (GGU 206054, > 51000 B.P.) found at an attitude of 260-245 m above sea level must be situated well above the Holocene marine limit
In Hall Land, three new dates indicate an age for the marine limit (108±2 m above sea level) at 9500-10000 years B.P
Summary
The Holocene marine inundation in Olrik Fjord reached 45±5 m above sea level and modified the interglacial sediment locally; a shell sample previously dated from the eastern flan k of eastern Kugssuaq delta in Olrik Fjord (GGU 166125, 18 990±280 B.P., Weidick, 1976a) is from a site approximately 14 km east of the sites of GGU 226427 A & B). This date might be based on a mixed shell assemblage of Holocene and interglacial age (cf Weidick, 1976b).
