The calcareous nannofossil assemblages recovered from Site 677A range in age from latest Miocene (NN11) to latest Pleistocene. The consistently high sediment-accumulation rate (mean of 48 m/m.y.) coupled with little dissolution of carbonate has ensured that generally rich, well-preserved coccolith assemblages occur at this site. Exceptions are the Pliocene/Pleistocene boundary sediments, which show evidence of dissolution, and upper Miocene basement sediments, which show evidence of diagenetic overgrowths.The apparent paradox of the occurrence of large numbers...
