Submarine carbonate breccia beds—a oppositional model for two-layer, sediment gravity flows from the Sekwi Formation (Lower Cambrian), Mackenzie Mountains, Northwest Territories, Canada

Abstract

In the Sekwi Formation, carbonate breccia beds interbedded with slope sediments are interpreted as submarine sediment gravity flows that formed a two-layer deposit during a single transport event. They are intermediate between true slumps and turbidites and may initiate by slumping anywhere on the continental slope and rise. Textural characteristics of the deposits are a function of downslope transport distance.
