Abstract
The Lower Palaeozoic stratigraphy of the East Greenland Caledonides, from the fjord region of North-East Greenland northwards to Kronprins Christian Land, is reviewed and a number of new lithostratigraphical units are proposed. The Slottet Formation (new) is a Lower Cambrian quartzite unit, containing Skolithos burrows, that is present in the Målebjerg and Eleonore Sø tectonic windows, in the nunatak region of North-East Greenland. The unit is the source of common and often-reported glacial erratic boulders containing Skolithos that are distributed throughout the fjord region. The Målebjerg Formation (new) overlies the Slottet Formation in the tectonic windows, and comprises limestones and dolostones of assumed Cambrian–Ordovician age. The Lower Palaeozoic succession of the fjord region of East Greenland (dominantly limestones and dolostones) is formally placed in the Kong Oscar Fjord Group (new). Amendments are proposed for several existing units in the Kronprins Christian Land and Lambert Land areas, where they occur in autochthonous, parautochthonous and allochthonous settings.
Highlights
The Lower Palaeozoic stratigraphy of the East Greenland Caledonides, from the fjord region of North-East Greenland northwards to Kronprins Christian Land, is reviewed and a number of new lithostratigraphical units are proposed
This paper documents the key stratigraphical observations on Lower Palaeozoic rocks made during expeditions from 1993 to 1995 by the former Geological Survey of Greenland (GGU) to Kronprins Christian Land and Lambert Land (78°–82°N), and the 1997–1998 field work by the Survey in the Kong Oscar Fjord region (72°–75°N)
The Lower Palaeozoic sediments of Kronprins Christian Land and Lambert Land (Fig. 2) were deposited on a subtidal to peritidal platform that constituted the south-easternmost part of the Franklinian Basin (Higgins et al 1991), and lay at a marked inflexion of the Laurentian margin where it turns through 90° between the present-day E–W-trending coast of North Greenland and the N–S-trending coast of East Greenland
