Stratigraphic and sedimentological studies of the Eleonore Bay Group (Precambrian) between 73° 30' and 76°N in East Greenland

Abstract

As part of the North-East Greenland Project 1988- 1990, a sedimentologieal study of the Precambrian Eleonore Bay Group between Grandjean Fjord and Bessel Fjord (75°-76°N) (fig. 1) was planned to start in 1988 with one two-man team and to eontinue in 1989 with two teams. This area was last visited in 1955 when Sommer (1957) as a member of Lauge Koeh's expeditions to East Greenland earried out the mapping. This work, however, only dealt with stratigraphie and teetonic problems, and sedimentological data, apart from gross lithologies, were not recorded. Unfortunately, the field work of 1988 quiekly revealed that the sediments had suffered from a relatively strong metamorphie recrystallisation, and henee it was generally not possibie to earry out detailed sedimentologieal work in this arear As a eonsequenee the team eoneentrated on stratigraphie problems, and atter 3 weeks the working area was moved southwards to Vibeke Sø (Hudson Land) and Brogetdal (Strindberg Land) (fig. 1) where the rest of the season was spent.
