Quaternary palynology ‐ its scope, problems and potential uses

Abstract

Abstract During the past fifty years the scope of Quaternary palynology has widened appreciably. Many other kinds of microfossils besides pollen and spores are included in the field of study. The use of modern data processing methods and the scanning electron microscope are recent additions to the “tool box” of palynology. Research on autofluorescence of fossil pollen is one of several new techniques available to a palynologist concerned with redeposition of pollen. Quaternary palynology is being used in geological studies to identify and describe different facies in sedimentary basins in terms of palynomorph assemblages and sedi‐mentological characteristics. These Quaternary models are then used in the interpretation of pre‐Quaternary environments. There exist serious deficiencies, however, with regard to our current knowledge of palynomorph morphology and their dispersal, deposition, and preservation. The relationships between fossil palynomorph assemblages and the parent populations which produced them are insufficiently known. The true potential of Quaternary palynology is rather evident but cannot be fully utilized until the necessary information on basic palynology is forthcoming. It should be realized that long‐term, detailed studies must be undertaken, instead of seeking “instant” answers to our problems in Quaternary palynology.
