Abstract

Major erosion surfaces cutting into basement rocks define several submarine paleocanyons. Paleocanyon fills consist of large, lenticular conglomerate bodies that are 200-580 m thick and 3-6 km wide. The best example of these paleocanyons is located near the town of Stilo. The conglomeratic canyon fill and the adjacent muddy slope deposits are both overlain by a laterally continuous sequence, 160 m thick, composed of two units of fine-grained, thin-bedded turbidites alternating with two units of thicker sandstone and minor pebble-conglomerate beds. The paleocanyons probably originated as subaerial valleys in response to a major fall in relative sea level at 30 Ma and were later submerged by a combination of relative sea-level rise and concomitant tectonic activity. -from Authors
