Title from cover. Includes bibliographical references. "Fossil pollen concentration is relatively low in cores of sand-rich nearshore lacustrine sediment because pollen is hydraulically equivalent to, and tends to be associated with, the silt-clay component of the sediment. Concentration can be increased to levels suitable for pollen dating by removing the sand fraction by decantation and then applying the standard Quaternary pollen-preparation procedure (Faegri and Iversen, 1964) to the silt-clay residue"--Introduction, page 1.
