Laminated silts and clays recovered by coring and drilling in Swansea Bay are shown to be of lacustrine origin. Similar deposits penetrated by boreholes onshore in the Swansea area have also been ascribed to a lacustrine origin by several authors; a map showing the shape and distribution of five lakes in this area has been produced. Stratigraphic relationships and palynological evidence indicate that the lacustrine conditions probably lasted from about 16,000 to 10,000 years B.P.
