S ummary Samples from cores taken in the central and marginal areas of Hoxnian lacustrine beds at Marks Tey have been analysed for diatoms. Diatoms are extremely scarce in samples from the marginal areas. Non‐planktonic diatoms dominated the early parts of the interglacial. The change to planktonic dominance took place during the early‐temperate zone HoII. Stephanodiscus astraea var. minutula was the leading planktonic diatom. No diatoms have been found in deposits of post‐temperate age (zone HoIV), nor in the succeeding glacial deposits (Gipping Early‐glacial zone). In the Lowestoftian Late‐glacial deposits diatoms are scarce and corroded.
