(Lower Chalk, Red Chalk and Carstone) - 2005

At Hunstanton the Lower Chalk overlies a conspicuous bed called the Hunstanton Red Rock (forma or Red chalk). Although these two beds the Lower Chalk and Red Rock (also known as Red Chalk) are different in appearance, a mineral analysis shows that there is a gradual passage between them which is one of the reason why the Red Rock is also known as the 'Red Chalk'.

(Lower Chalk) - 2003

The sandy constituents and the distinctive heavy minerals of the Carstone continuing to the top of the Red Rock, but in diminishing amount. When compared with evidence of fossils of the basal Carstone beds, it seems rather strange that these show no continuity. In the Carstone, fossils are restricted to this base, and only some 35ft of Carstone intervene between this horizon and the fossiliferous beds of the Red Rock.

(Carstone) - 2003

Three bands can be recognised in the Hunstanton Red Rock, the lowest is deep-red and gritty and contains abundant quartz pebbles; the middle is a rough nodular red limestone; and at the top is a bed of hard light-red or pink mottled limestone.

(Red Chalk) - 2003

The fourth ice-advance gave rise to a reddish brown boulder clay, found not only at Hunstanton but other places on the northern coast of Norfolk. The erratics are different from those of previous glaciations; they include grits and igneous rocks similar to those found in the Cheviot hills.
