Clay-with-Flints

In geology, clay-with-flints is the name given by William 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.[1]
