Abstract
Sediment and peat chronologies have been further improved allowing alternative radiometric methods to complement14C dating. Lacustrine and coastal marine sediments as well as peat deposits in various parts in Scandinavia are studied using137Cs,210Pb,14C and other methods primarily to evaluate the210Pb but also to extend the14C chronology. The sampling sites have various sources of input and are characterized by different geochemical, depositional, and post-depositional conditions.
