Abstract

This paper presents descriptions and preliminary interpretations of sedimentary sequences exposed in coastal sections near Tors Cove, 40 km south of St. John's, on the Avalon Peninsula, Newfoundland. Interbedded diamictons and pebbly mud, up to 20 m thick in places, outcrop discontinuously along the coast and on offshore islands. Diamictons, which comprise the bulk of the coastal deposits, have a sandy matrix and generally appear stratified with some evidence of inverse grading. Erratics and striated clasts are common. Individual clast fabrics display a range of azimuths in a gridle-type pattern. These characteristics suggest a debris flow origin for the diamictons, possibly in an ice-marginal environment, as glaciers retreated inland to local ice centres on the Avalon Peninsula.
