Abstract
It is common practice to count charcoal particles alongside pollen and non‐pollen palynomorphs in palynological samples. The classification of material as charcoal is dependent upon a number of morphological criteria which, in certain geological zones, could be misclassified. In a preliminary study we tested the effects of different preparation techniques on the count result of charcoal from the same samples of Greenland lake sediments. We demonstrate that the use of hydrofluoric acid has a major impact on the number of recorded charcoal particles. We show that detrital biotite is responsible for a large fraction of the particles misclassified as charcoal and suggest that by using a neodymium magnet any inaccuracy can be minimised. This protocol was then applied to further samples which removed the biotite fraction from the total charcoal count.
