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.[1]
Formation
The formation is now considered to be a combination of residual and cryoturbated strata, and to be of a variety of ages.[2][3]
