| contents | Benthic foraminifers have been studied in about 900 samples from Sites 642, 643, and 644 (ODP Leg 104, Voring Plateau), ranging in age from Eocene to Holocene. This sequence has been subdivided into seven assemblage zones. The Eocene to middle Miocene deposits are characterized by an agglutinated fauna. This reflects an environment causing dissolution of calcareous tests rather than the original living fauna. The upper Miocene to middle Pliocene deposits contain a diverse benthic foraminiferal fauna dominated by calcareous forms. The uppermost part of the sediment record, deposited during late Pliocene to Holocene, is characterized by many barren intervals and samples containing shallow-water species as well as ice-rafted material indicating glacial periods. Interglacials are reflected in samples containing a true oceanic foraminifer assemblage and no coarse clastic material. |
