Absolute and relative pollen diagrams from northernmost Fennoscandia
Absolute and relative pollen diagrams from three radiocarbon‑dated lake sediment cores were used to illustrate the Flandrian vegetation history of an area between Lake Inari and Varangerfjorden in northernmost Fennoscandia. The area is traversed by the modern pine forest limit and by the Main sub‑st...
