This variety of silica is termed ‘chert’, often referred to colloquially as ‘flint’ by the aboriginal inhabitants of the Cretaceous Chalk downlands of south-east England. Chert is a non-clastic cryptocrystalline variety of silica that occurs as nodules and horizons in limestones and sandstones ( Figure 14 ).Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.
