Like most other sedimentary rocks, most limestone is composed of grains.Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.These organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die.Other carbonate grains composing limestones are ooids, peloids, intraclasts, and extraclasts.
