Although some limestones form by inorganic chemical precipitation most limestones are biochemical because they are mostly composed by organisms. Examples of limestone include Coquina composed almost entirely of fragmented seashells and Chalk, composed largely of microscopic shells.

What is the chemistry of limestone?

The limestone consists mainly of calcium carbonate: CaCO3 ,Calcite. Like most other sedimentary rocks, limestones are composed of grains, however, around 80-90% of limestone grains are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. (i.e. travertine.)
