Abstract/Summary This study discusses the results of using pollen concentrate for AMS C14 dating of sediments from the Ocean Drilling Program (ODP) 820 marine core and these dates are compared with existing AMS C14 dates derived from foraminifera for the same record. This will address the question of reworking, and consequent time lag between production and deposition of pollen in the Queensland Trough, as well as providing an additional age model from the terrestrial record (i.e. pollen) that can be directly compared with the existing age model derived from marine sediments (i.e. foraminifera). In addition, these results will contribute to our ability to interpret marine palynological records and provide additional insight into the sedimentological processes operating on the northeastern Queensland continental margin.
