WebVarieties of limestone that contain abundant sand-size allochems like oöids and fossil fragments are, in at least a textural sense, types of sandstones, although they are not terrigenous siliciclastic rocks. Such rocks, called micrites when lithified or carbonate sands when unconsolidated, are more properly discussed as limestones.
