Lutite
Lutite (Latin lutum "mud") is a sedimentary rock with an average grain size of less than 2 µm. A lutite corresponds to rocks that can be assigned to clay stones . The term lutite is mainly used in the classification of limestones , where the grain size-dependent term mudstone does not make sense because it primarily only refers to siliciclastic rocks.
