Clay-with-Flints

In geology, Clay-with-Flints was the name given by W. Whitaker in 1861 to a peculiar deposit of stiff red, brown or yellow clay containing unworn whole flints as well as angular shattered fragments, also with a variable admixture of rounded flint, quartz, quartzite and other pebbles.

Occurrence

The Formation is associated with deposits of the Chalk Group, subsequent Palaeogene and Neogene strata, and occasionally Upper Greensand.

Formation

The formation is now considered to be a combination of residual and cryoturbated strata, and to be of a variety of ages.[1][2]
