The group was later extended to include the Mârmorilik Formation (Henderson & Pulvertaft 1987) originally considered to be of Archaean age (Henderson & Pulvertaft 1967) but later shown to be Palaeoproterozoic, resting with a depositional unconformity on Archaean gneiss (Garde 1978). Henderson & Pulvertaft (1987) suggested that the carbonatedominated Mârmorilik Formation in the south was laterally equivalent to the siliciclastic-dominated Qeqertarssuaq Formation in the north, the two subbasins being separated by a basement topographic high.</p>}, journal={GEUS Bulletin}, author={Guarnieri, Pierpaolo and Partin, Camille A. and Rosa, Diogo}, year={2016}, month={Jul.}, pages={63–66} }
