Abstract

Tufa information began sometime after c9700 BP when the valley was relatively unshaded except for occasional patches of Betula woodland. An expansion of shade-demanding Mollusca occurs at c400 cm from the top; pollen analyses from these levels indicate the presence of Corylus avellana scrub. A radiocarbon date of 7360+ or -60 BP was obtained from charcoal from a buried soil between 345-350 cm. Above this point there is little change in the composition of the land Mollusca although a pollen from 150 cm indicates that Pinus sylvestris has now become an important forest constituent in the valley. Occurrence of the land snail Vertigo alpestris, known living at only 2 Scottish sites, is noteworthy. Cessation of the tufa formation probably occurred sometime after c6000 BP.-from Authors
