Flint.

Flint.

Flint, sometimes referred to as chert by geologists, is a cryptocrystalline form of quartz,  SiO2  Very often it is found in chalk deposits as nodules. These specimens which I collected from Sandringham warren in Norfolk interested me because of their non-nodular appearance. The one in particular seems to be a cemented collection of small irregular shaped pieces of flint. The location is from a footpath cutting through a small area of higher ground which exits the warren. Pieces of flint are eroding from the narrow cutting through which the footpath has been cut.
