The buried western extension of the Navarana Fjord escarpment in central and western North Greenland

Abstract

Three lines of argument are presented in support of the existence and location of a presumed western buried extension of the Navarana Fjord escarpment: (1) comparison between sediment thickness of two adjacent sections on either side of the escarpment; (2) the occurrence of limestone boulder conglomerates at the base of the Merqujôq Formation; (3) abrupt changes in deformation style and intensity across the region controlled by the escarpment.
