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.

Loose, solid particles that can originateby (1) weathering and erosion of preexisting rocks, (2) chemical precipitation from solution, usually inwater, and (3) secretion by organisms.

Sandstone, a sedimentary rock, is formed when grains of sand are compacted and cemented together over thousands or millions of years. The sand grains often are composed of the minerals quartz or feldspar that were worn off other rocks and ground down into pebbles.
