FOSSIL DIATOMS AND THEIR SIGNIFICANCE IN ARCHAEOLOGICAL RESEARCH

Abstract

Summary. The relationship between environmental archaeology and diatom analysis, a well established technique in palaeoecology, is explored. The development of diatom analysis for palaeoenvironmental reconstruction is briefly considered and flow diagrams are presented to illustrate laboratory techniques. Examples of research in Mexico, North America, Britain and Europe are discussed to illustrate the potential of diatom analysis as a means of assessing human impact on the environment, notably lake water quality, and as a means of elucidating the palaeoenvironmental conditions under which archaeological sediments have accumulated. Consideration is also given to the role of diatom analysis in examining land/sea‐level changes, especially those which may have affected prehistoric resource use, and to its significance in the reconstruction of local environments in and around archaeological sites. Finally, the potential of fossil diatoms for provenancing pottery is explored with particular reference to Dutch and Finnish examples.
