Sedimentological investigations of the Multicoloured 'series' (Eleonore Bay Group, Late Precambrian) in the Scoresby Land – Andrée Land region, North-East Greenland

The approximately 1200 m thick Multicoloured 'series' (bed-groups 7–13) and adjacent units of the upper Eleonore Bay Group have been the subject of detailed sedimentological investigation during 1989 in the area between northern Scoresby Land and Andree Land in North-East Greenland. The Mu...

More Information
Summary:The approximately 1200 m thick Multicoloured 'series' (bed-groups 7–13) and adjacent units of the upper Eleonore Bay Group have been the subject of detailed sedimentological investigation during 1989 in the area between northern Scoresby Land and Andree Land in North-East Greenland. The Multicoloured 'series' consists of alternating units, 100–300 m thick, of carbonate and siliciclastic deposits which are uniformly developed throughout the central fjord zone. It represents the transitional stage from a pure siliciclastic shelf environment to a carbonate platform environment. During its development initial carbonate sedimentation was repeatedly terminated by drowning and siliciclastic deposition, until a large carbonate platform represented by the overlying Limestone-Dolomite 'series' was firmly established.
