Description and Reasons for Notification:


The tufa deposit at Blashenwell Farm is important for Quaternary studies, providing a detailed record of molluscan biostratigraphy and environmental history during the early-and mid-Flandrian (mollusc assemblage zones b to d). It is particularly valuable for the length and continuity of the record and the dating potential provided by the presence of associated archaeological remains. Several radiocarbon dates are also available from the site.
