On the basis of profile and topography, three carbonateshelf margin configurations in North Greenland are identified as having been formed during the Silurian. They include escarpment margins which are abrupt and characterized by slope angles of 35/sup 0/ to 40/sup 0/; stepped margins consisting of blocks downstepping into the deep-water basin and with the slope angle inclined from a few up to 40/sup 0/; and ramp margins characterized by gentle slopes and lack of a pronounced break between carbonate shelf and deepwater basin. The carbonate-shelf margins are related to the Navarana Fjord fault and Permin Land flexure. The stepped margin had a similar origin and relation to controlling faults, but later shelf-margin downdropping of blocks may have been contemporaneous with shelf sedimentation.
