Shelf-Edge Architecture and Bypass of Sand to Deep Water: Influence of Shelf-Edge Processes, Sea Level, and Sediment Supply

摘要

Analysis of two Maastrichtian depositional cycles from the Lewis–Fox Hills shelf margin (S. Wyoming, U.S.A.) demonstrates that rivers played the driving role in the bypass of sand to deep water. Waves and tides were of less importance, but they had a significant influence on the relative storage and architecture of sand along the shelf edge, which in turn appear to have been driven by relative sea level and sediment supply.
