Patterson, R.T., and Luternauer, J.L. 1993. Holocene foraminiferal faunas from cores collected on the Fraser River delta, British Columbia: a paleoecological Interpretation: Current Research, Paper 93-1A:245-254.
Interpretation of sedimentary environments are made based on the foraminiferal faunas recovered from four cores (FD90-A, FD90-B, FD91-1, and FD91-2) collected on the Fraser delta. These relatively short cores (<55 m) are primarily comprised of prodelta sands overlying ancetral Strait of Georgia mud and silt. The muds and silts are characterized by a low diversity foraminifera fauna, dominated by Buccella frigida, Cribroelphidium excavatum, and Elphidiella hannai. This fauna is typical of low salinity, neritic depth conditions. foraminifera are virtually absent from the prodelta sands as the winnowing conditions prevalent during deposition of this unit made colonizaiton difficult.
