Pelite (Greek pelos, clay) is a descriptive name for a clastic rock with a grain size of less than 1/16mm (originally sand or silt). Examples include slate and mudstone. The equivalent Latin-derived term is lutite. Pelite is more commonly used for a metamorphosed sediment (which should technically be called a metapelite).
