In 1836 Rose (Phil. Mag., viii, p. 30) described a series of marine deposits in the Nar Valley, associated with the brick clay of that neighbourhood. Later work revealed that these beds were widely distributed to the south-east and east of King’s Lynn, and were to be correlated with very similar gravels at March and Whittlesey. Further correlation outside this area is uncertain, but following Boswell’s scheme (1932, pp. 72, 75) the March-Nar marine episode may be classed with the well-known estuarine sections at Kirmington, Lines.: moreover, he refers all gravels containing Corbicula (including the Barrington gravels) to this period. The same author regards the uppermost boulder clay at Kirmington as of Upper Purple age, and “apparently not the equivalent…of the Brown boulder clay of Hunstanton”
