Sedimentary Chalk Rocks

Chalk: A biological limestone formed from shell debris

Chalk is widely known among the people of western Europe and a few other parts of the world because it is a bright white rock that can form vertical cliffs along shorelines. The chalk cliffs are eroded at water level by wave action, and as the base of the cliff is undercut, collapses occur when the undercutting reaches a vertical joint or other plane of weakness.

Chalk - Wikipedia

Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceousorganisms as water is e…
