摘要:
Clay and clayey sediments usually have a low content of pollen and consequently some form of enrichment is required before a pollen analysis can be performed. The cotton wool method offers the opportunity of concentrating pollen from samples containing clay in a quick and effective manner. It involves removing the clay fraction from the deflocculated sample by filtering through a cotton wool filter. The residue left on the filter is then removed and concentrated by density separation.
