Abstract
Summary: Boreholes at, and seaward of, Lantern Marshes shed additional information on the Quaternary evolution of the Orford, Suffolk, area. The logs indicate:(i) a more complex surface to the London Clay, which is shown to reach depths below those formerly thought;(ii) the reality of the lower planation surface previously recorded. The surface is, however, cut across Scrobicularia and Butley (Red) Crag to a greater extent than anticipated. It proves that at least part, and probably all, of the −8.5 to −11 m surface is post Ludhamian.(iii) a peat sample from −9.4 m indicates that relative mean sea level at 7010 B.P. was at approximately −10.7 m. The peat is overlain by shingle and confirms the residual shingle structures as later than that time.Keywords
