Corals deposit a skeleton made up of the mineral aragonite, which is a form of calcium carbonate (CaCO3). X-radiographs of coral skeleton slabs show alternating light and dark layers (bands) that are the result of seasonal changes in growth rate and differences in skeletal density. A couplet of light and dark layers (bands) represents 1 year of growth and can be used to determine the age of the coral by counting back and down the coral from the known year it was sampled.
