Description
Area, 1.46 ha. 3.60 ac. Description This locality shows exposures of the controversial Lenham Beds;deposits variously assigned a Miocene, Pliocene or Pleistocene age by geological authors in the past. They are now, on the basis of their marine gastropod and bivalve fauna, placed in the Pliocene. Lenham Beds lithologies of sand, flints derived from the underlying Chalk and ironstone are present here in pipes up to six metres deep. This is an important site showing deposits from a period otherwise poorly represented in Britain.
