Excerpt from Proceedings of the Linnean Society of New South Wales, Vol. 118: June, 1997 Samples of about 1 cm3 of sediment, taken at m intervals throughout the core, were prepared using kohand HF digestion, and acetolysis (moore et al. Known quantities of Alnus rugosa pollen were added to the samples in order to obtain concentra tion (absolute) values for pollen and charcoal. Residues were mounted in silicone oil. Quaternary pollen and spores were abundant and well preserved at almost all levels. Thus in spite of a small component of degraded, reworked Fermo - Triassic palynomorphs in a number of samples, significant redeposition of those of Quaternary age (by water as a result of riverbank erosion, for example) seems unlikely. At least 300 grains and spores of terrestrial taxa (excluding exotic pollen) were counted at each level, and formed the sum for the percentage calculations. Charcoal frequencies were obtained using the point count method (clark Both percentage and concentration pollen data were obtained. Separate pollen diagrams (figs 3 and 4) were drawn using the tilia computer package of ec. Grimm, Illinois State Museum, and both were zoned independently by.
