Shale is usually found in thin layers. The silt or clay that composes shale is made of very small pieces of weathered rock. The pieces are from 1/16 to 1/256 of a millimeter in diameter. 5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments.
