Abstract
The dolomitized Hopegate Formation, a late Pliocene raised reef, formed rocky shorelines of two distinct morphologies during the Sangamonian (=oxygen isotope substage 5e; late Pleistocene). The older shore (130,000 yr bp) is typified by re-excavated coastal cliffs and a sloping shore platform ('Type-A Platform') that formed the substrate for the growth of the Falmouth Formation reef during a sea-level highstand. The younger shore (105,000 yr bp) formed after regression and the deposition of the Falmouth Formation, and is comprised of sea cliffs, a horizontal shore platform (= reef terrace) and a marked seaward drop ('Type- B Platform'). Deposition of the Falmouth Formation thus led to a gross change in shoreline morphology during a geologically brief time interval.....
