The outwash deposit is composed of 90 per centcobbles and 10 per cent shells (Parker 1968). The shells are mainly disarticulated. Parker (1968) recognized two distinct units at Churchhaven which heseparated accordingly to lithology and the mollusc fossils. He recognized thatthe lower unit was not a shoreline feature, but a lagoon floor deposit. Hebelieved the outwash deposit to be a 4,3 m shoreline. Davies (1973), on theother hand, recognized only

The outwash deposit occurs at varying altitudes in this region, that at4 m being the highest exposure. Pie diagrams comparing the molluscand ostracode assemblages from the two horizons (Figs. 8, 22) confirm Parkersinterpretation. But the field evidence shows that the shelly conglomerate isnot an in situ marine unit, but rather a colluvial deposit that has gravitated PLEISTOCENE HISTORY AND COASTAL MORPHOLOGY 107. Fig. 21.
