Foraminiferal assemblages in deep-water sediments contain: (1) indigenous benthic taxa that represent combined bottom-water and bottom-sediment controlled benthic environments (biotopes); (2) planktonic taxa that settle, after death, from near-surface habitats into benthic biotopes; and, (3) allochthonous benthic shelf taxa that are transported downslope into deep-water biotopes either as empty tests or as displaced living populations. Each of these categories of foraminiferal taxa contained in deep-water foraminiferal assemblages carries information on the sedimentary processes, lithology, and reservoir properties of deep-water biotopes, and on derivative foraminiferal biofacies called litho-biofacies.
Turbidites and particularly associated poorly-sorted submarine fan deposits known as debrites are...
