The Museum Collection: Rock and Stone Samples
The rocks of the Cotswold Hills in the west of the Bradford Hundred are largely limestones and calcareous mudstones and clays. They include the fine building stones that are called Bath Stone and were important in the local economy. The lower land to the east has more of the clays with some limestone bands.

A piece of pisolite from old quarries at Avoncliff, Westwood. It is a limestone rock that is largely made up of relatively large disc-like grains that precipitated from warm lime-rich sea water in tropical conditions.
