What types of clastic rocks r made of particles of clay?

Clastic rocks made of particles of clay are primarily classified as shale. Shale is formed from the compaction and cementation of fine-grained sediments, predominantly clay minerals. Other types of clastic rocks, such as siltstone, may also contain clay particles but have a higher proportion of silt-sized grains. Overall, shale is the most notable clastic rock specifically composed of clay-sized particles.
