Evoy, R.W., Moslow, T.F., Patterson, R.T., and Luternauer, J.L. 1993. Patterns and variability in sediment accumulation rates, Fraser River delta foreslope, British Columbia, Canada. Geo-Marine Letters, 13:212-218
Minimum sediment accumulation rates on the Fraser River delta foreslope exhibit a high degree of spatial variation, with accumulation rates ranging from 0.50 to 3.0 cm/yr. Accumulation rates generally increase towards Sand Heads channel, the active foreslope depocenter. Sedimentation rates and patterns and micropaleontological assemblages are interpreted to reflect reintroduction of older sediment from upslope via slumping and sediment-gravity flow processes. Such processes account for the bulk of sedimentiton in much of the subaquaeous delta. These processes provide a mechanism for sand bypassing of the delta plain and foreslope and for deliver of coarse-grained sediment directly to prodelta and basinal environments.
