Abstract

The Navarana Fjord Escarpment is a major sedimentological feature of the Franklinian Basin in North Greenland. A southern sequence of Ordovician-Silurian shelf carbonates forming the escarpment itself is juxtaposed across a steep scarp slope with a northern deep-water trough succession dominated by sandstone turbidites. The relief of the scarp can be estimated to many hundred metres on the basis of present-day exposures along Navarana Fjord and J. P. Koch Fjord, central North Greenland.

  • The Navarana Fjord Escarpment is a major sedimentological feature of the Franklinian Basin in North Greenland

  • The evolution of the Lower Palaeozoic basin in North Greenland was interpreted in terms of control by an east-west trending fault system by Surlyk et al (1980) and the Navarana Fjord Escarpment was originally ascribed to one of these faults; its significance has subsequently been discussed in a series of papers by J
