Palynological study of Recent Orinoco [Venezuela] sediments shows the relative influence of location of source area and transport by air and water currents on pollen dispersal. Distribution of fungi, cuticles, reworked material, Hystrichosphaeridae, and foraminifera have also been studied. Variations in microfossil content with depth in core samples are found to be related to depositional history. The significance of the results in palynological and paleogeographical studies of older sediments is discussed.
