Abstract
The present study is an attempt to determine local elements in pollen spectra obtained from analyses of various types of Postglacial organogenic sediments in Czechoslovakia. A survey of the local elements in algal gyttja (nekron mud), coarse detritus gyttja, brown moss peat, Carex peat, Phragmites peat, fen peat, Alnus carr (wood) peat, Sphagnum-Eriophorum peat, and Pinus carr peat is given in Table I. A short characterisation of the above-mentioned genetic types of sediments is also appended (pp. 166–167). From different types of sediments, several examples have been chosen to show the degree of possible error in quantitative ratios between the individual elements of pollen spectra. It is suggested that these errors may, in many cases, be corrected by eliminating local elements from the basic sum; but this elimination has to be differentiated according to the approximate floristic composition of the original peat-forming community, and it has to be performed separately for the different layers of the profile.
