Iversen suggested in 1936 that pollen analysis could be used to differentiate Quaternary tills. Heinonen (1957) distinguished various tills in Finland by pollen analysis. At Lindø, northeastern Fyn, in Denmark, boulder striations indicate three tills with different transport directions. These three tills, as sampled on one vertical section and a boring, differ in pollen and spore content, and three more horizons with unknown transport directions could be distinguished in the underlying tills. Extinct pollen and spore forms plus Varia pollen of pre-Quaternary age are particularly frequent in till horizons II, IV, and VI, and pollen and spores of extant taxa, mainly of Quaternary age, in horizons I, III, and V. Because till II came from the north, tills IV and VI probably also came from this direction, whereas tills I and III and probably V came from the southeast and east. The composition of the pre-Quaternary pollen and spore content does not vary substantially. The material is probably mainly early Tertiary and older, presumably originating in the Kattegat area. The Quaternary pollen and spore content is also uniform. It probably came from older tills with a high content of interglacial pollen. The age of interglacial peat smears in till III cannot be determined with certainty.
