This study provides the first detailed documentation of calcareous nannofossil assemblages in Eocene subantarctic Eltanin piston cores recovered from the southeast Pacific Ocean. These Eltanin cores are important because they have been reported to contain ice-rafted quartz. The present study confirms early and middle Eocene ages for the cores and dates them more precisely using calcareous nannofossils. Semiquantitative study of the nannoflora indicates that they are of a warmer water character than those from the higher latitudes (such as Falkland Plateau, Maud Rise, and Kerguelen Plateau). This study concludes that it is unlikely for the ice-rafted quartz in the Eocene sections to be downcore contaminants from the overlying Neogene sediment and suggests that the grains are probably the result of Eocene ice-rafting from Antarctica when the Drake Passage was closed and water circulation patterns were different from those of today. |
