In geology, clay-with-flints was 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.

WebThese flints are reworked and likely derived from clay-with-flints that outcrop on the slope. Coarse anorthic iron nodules with a diameter of around 500 μm provide a further indication of ex situ formation and increased erosive processes (Fig. 9 H). Those iron nodules characterize the SU G, as we can also see it on the PCA analyses (§4.2.4).
