Limestone - an overview ScienceDirect Topics

With one principal, and several other minor exceptions, most ancient limestone (and dolomite) deposits are analogous in character and origin to these modern carbonates of the Bahama Banks. The other principal volumetrically significant modern limestone deposits are the calcareous oozes that accumulate on the deep (3000 m+) ocean floors. These oozes are composed of the shells of carbonate-secreting

Limestone - an overview ScienceDirect Topics

Limestone areas throughout the Indonesian archipelago originate from jurassic, cretaceous, tertiary and quarternary times. Forests over limestone are usually a mosaic of rich and poor growth due to free-draining, steep slopes, water stress, high concentrations of calcium and magnesium, richer soils between jagged peaks and pinnacles.

Limestone Types, Properties, Composition,

Lithographic limestone is a type of limestone that contains fossils. Powered limestone is used in coal mines as a safety precaution because it absorbs pollutants. It can also be used on roofs to prevent or reduce weather or heat related roof damage. Its turns into the metamorphic rock marble when subjected to high amounts of pressure and heat.
