“…In Britain most of these sites are found south of the limits of the maximum extent of Late Devensian ice, but there are exceptions to this pattern, e.g. northern Isles of Scilly (Scourse, 1991a) and Broughton Bay, Gower Peninsula (Campbell et al, 1982). In southern Ireland many of the raised beach sites lie within the assumed Late Midlandian ice limit.…”

“…In recent years the scope. of amino acid geochronology has widened, and recently we have been involved in determining amino acid D L ratios on whole valves and shell fragments from marine, glacial marine andlor till units (Nelson 1982;Andrews ef deposits on Baffin Island, in the Hudson Bay Lowlands, and around the shores of the Irish Sea (Andrews et al 1982).…”

“…Second, moraine sediments have indeed not been found overlying erratic‐bearing interglacial fossil beach deposits, as Bowen () considered important in arguing for a pre‐Devensian age, but: (i) the moraine is restricted to the limestone plateau well above any fossil beach fragments, and so lack of superposition is unsurprising; and (ii) moraine clast lithologies essentially differ little from those in glacitectonite of accepted Devensian age in Broughton Bay, where superposition has been observed (Campbell et al . ; Campbell ). At both sites, Welsh Coalfield lithologies dominate: these and more exotic lithologies with a west or northwest provenance have been reported from fossil beach and glacigenic sediments both in coastal sequences distal to the moraine and, more rarely, farther east in Gower (e.g.…”
