Late Devensian and early Flandrian vegetational history and deglacial chronology of Western Argyll
… stadial became increasingly arid. One site was C 14 dated, but results showed errors due, perhaps, to graphite in shallow till in the catchment. The early postglacial pollen sequence was examined in detail with regard to the consistency of representation of pollen-types, possible syncroneity and …
