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. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.

Illite abundance may also relate to authigenic illite within exposed sandstones, or result from weathering of argillaceous sedimentary rocks (Pearson, 1990). Illite and related mixed layer minerals (e.g., illite-smectite) can be found particularly in arid and semi-arid regions, where poorly drained areas ensure minimum leaching.
