Classification of sedimentary rocks

Some examples of sedimentary rocks. Chalk is a fine-grained limestone, usually formed by compacted microscopic animals called foraminifera. Chert is a fine-grained hard sedimentary rock composed of microscopic silica grains, and has a flat fracture. Flint is a variety of chert (mostly of upper Cretaceous age) that has a conchoidal fracture.
