Three samples from Lower Venson Farm Borehole (TR35SW/27; TR3083 5305) were
examined. The foraminiferal faunas from 52 and 57 m depth indicate foraminiferal zone BGS13
and it is suggested that both are from the Lewes Chalk. The sample from 47m contains a fauna
from low within zone BGS14 and the very basal part of the Seaford Chalk (immediately above
the Upper East Cliff Marl, and lateral equivalents) is inferred
