A METHOD FOR ESTIMATING THE MIGRATION TIME OF PLANT SPECIES WITHIN THE TIME RANGE OF 14C-DATING

Two hundred and fifty C-14 dates available from the French Massif Central, Germany and From High Belgium are discussed from a new point of view. It is shown that in an area of the French Massif Central as small as 100 x 100 km, Holocene pollen features in pollen diagrams can be treated as biostratigraphic tools delineating time ranges of several centuries. Larger time ranges characterize the Early Holocene warming (Quercus, Corylus), and shorter ones, the Middle Holocene (Tilia, Fagus). The method of calculation described in this paper can be applied within any area. (C) 1998 INQUA/Elsevier Science Ltd. All rights reserved.
