Late‐Glacial radiocarbon‐ and palynostratigraphy on the Swiss Plateau

摘要: A detailed late-glacial radiocarbon stratigraphy for the Swiss Plateau has been established on basis of over 90 accelerator 14C dates terrestrial plant macrofossils. Two plateaux constant.,14C age were observed, occurring at 12,700 B.P. and 10,000 The consequences these palaeo-ecological investigations are threefold: (1) a more refined dating within is not possible, (2) in teleconnections between different sites (if based concerning periods around B.P.) events considered synchronous which only plateau constant age, (3) exact time-depth relationship therefore influx calculations made impossible during periods. comparison ages derived from terrestrial, telmatic limnic material yields proposal modifying zonation system Welten Late-Glacial. By retaining limits chronozones (at 13, 12, 11 10ka by refining palynostratigraphic criteria biozones, separation chrono- biozonation beginning Belling Younger Dryas becomes obvious.
