Comment on shear zones in the Navarana Fjord Escarpment, J.P.Koch Fjord, central North Greenland

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.
