SKU: SEDROK045 Category:

This Middle Jurassic oolitic limestone is a carbonate rock made up mostly of ooliths (or ooids) which are sand-sized carbonate particles (0.25 -2.0mm) built up of concentric shells of precipitated calcium carbonate CaCO3. These layers were formed around sand grains or shell fragments that were rolled around in lagoons or on a shallow sub tropical sea floor, gathering layers of carbonate. Around the Cotswold Hills, the honey coloured stone has been the favoured building material for centuries & can be seen in many of the local picturesque hamlets. The rock tends to be a little more friable than the example from Yorkshire. Each specimen is supplied in a labelled card tray.
