White Coloured Chalk Powder is resistant to weathering and slumping compared to the clays with which it is usually associated, thus forming tall steep cliffs where chalk ridges meet the sea and is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite. The Powder can hold a large volume of ground water, providing a natural reservoir that releases water slowly through dry seasons. The Powder forms under relatively deep marine conditions from the gradual accumulation of minute calcite plates shed from micro-organisms called coccolithophores. The White Coloured Chalk Powder is capable of providing efficient performance.
