Highlights

Inclined heterolithic stratification (IHS) is a common sedimentary structure.  Sisulak and Dashtgard point out that this sedimentary structure recently has been recognized in a variety of sedimentary environments, and document the sedimentological and ichnological character IHS in a tide-influenced, fluvially dominated portion of the Fraser River.  The results indicate that the sedimentologic style and bioturbation patterns of IHS are closely related to seasonal cycles of freshwater discharge.  These insights provide an actualistic example of IHS, and an enhanced conceptual model for its deposition and internal heterogeneity.
