Limestone is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg (CO 3) 2 ). It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil ...

The dune-field, shown here, is fronted on the right side by a long sinuous slip-face down which sand avalanches. It is advancing landward into the forest (to the right) at approximately 1 m (3 ft) per year. Episodes of dune activity similar to this were occurring on Bermuda during the Pleistocene epoch.
