Pot and gutter casts from the Chapel Island Formation, Southeast Newfoundland; discussion and reply

Abstract

Myrow has recently presented a case for pot and gutter casts produced by erosion under unidirectional flow. Most pot and gutter casts are considered to be storm generated features initially under strong offshore-directed unidirectional flow. the currents that produce the structures are related to nearshore marine setting, where sediment by-passes proximal area, and where erosion is the dominant process. Pot and gutter casts are recognised a wide range of environments from tidal flat to submarine fan. It should be noted that linear erosional structures, which have been given various names (such as linear scours, longitudinal furrows), but falling under the general umbrella term of gutter casts, are also known in ancient fluvial deposits.
