• How is limestone formed? What is limestone? Limestone

    Some limestones are made of, or incorporate fragments of, preexisting limestones (detritus). In shallow waters, fringing reefs, barrier reefs, atolls and limestone shorelines are eroded by the sea. The resultant sediment is transported by currents and deposited on the flanks of the reefs and in sheltered lagoons.
