Samples of Danish glacial sediments have been analysed for palynomorphs. It is shown that the majority of dinoflagellates and acritarchs are reworked from the pre-Quaternary subground. On the basis of an approximate stratigraphic grouping of the palynomophs, the microplankton content can be divided in a parautochtonous and an allochtonous group relative to the local pre-Quaternary subground. Thus, the matrix of the glacial deposits appears to have been transported considerably shorter than the clasts. This indicates that the majority of clasts in Danish tills has been transported during several cycles of reworking and deposition.
