Survey of pollen and spores, Deep Sea Drilling Project Leg 96.

Abstract

A preliminary palynological survey of 118 samples from the Mississippi Fan (Sites 615, 616 and 620) and from 2 intraslope basins (Sites 619 and 618) shows pollen in all samples. Reworked pollen is generally abundant, forming over 50% of the sum of pollen and reworked pollen. Concentration of nonreworked pollen is usually low (on the order of tens of hundreds of pollen grains per cubic centimeter wet sediment). Conifers, primarily Pinus, Picea and Tsuga, dominate Pleistocene marine pollen spectra; significant percentages of Quercus are present in Holocene sediments and in sediments deposited during oxygen-isotope Stage 5.-Author
