Mesozoic palynofloras from the Mac. Robertson shelf, East Antarctica: geological and phytogeographic implications

O'Brien, Philip Edward; Dettmann, M; Truswell, Elizabeth


Gravity cores taken from five sites in the Nielsen basin, a sinuous trough on the Mac. Robertson shelf of the East Antarctic continental margin, have yielded non-marine palynofloras of late Early Jurassic to Early Cretaceous age. The palynomorphs occur in glacimarine muds and are thus not in situ, but the composition of the samples indicates that no mixing of individual assemblages has occurred, and that the sediments were deposited very close to outcrop of the source of the palynomorphs.
