In the light of the latest data the rock succession of Iceland has
considerably smaller gaps. Paleobotanical and paleozoological in-
vestigations of the Soviet Expedition (1, 15, 21), supplementing
earlier works, and certain recent absolute age determinations (17,
26 and the data of our Expedition) allow us to suggest a strati-
graphical scheme of Iceland, as seen on Table 1. The distribution
of separate stratigraphic division is shown in Fig. 1.
In the absolute chronology, the Miocene layer of plateau-basalts
covers the period from 16 to 5.5 million years before present. Using
the flora M. Akhmetiev has defined three horizons: Lower-Middle
