N2 - In the Rinkian belt of West Greenland, reworked Archaean gneisses are
overlain by supracrustal successions of the Palaeoproterozoic Karrat
Group, defined by Henderson & Pulvertaft (1967) as comprising two
formations: the Qeqertarssuaq Formation and the Nûkavsak Formation. 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.
