However, a lacustrine phase followed by significant pedogenesis is also documented in the basal part of sedimentary cores from the centre of Lake Frome (Bowler et al., 1986;
De Deckker et al., 2011). By correlation to our Unit 1b, this may suggest MIS 5d ages for the basal weathered sediments in these cores followed by an episode of subaerial exposure in MIS5c, but more detailed chronological data are required to confirm this scenario.
