Beerbower (1964) was the first to clearly distinguish between within-basin and extrabasinal sedimentary controls. The first, which he termed autocyclicity, refers to the redistribution of sediment within a depositional system as a result of processes inherent to the system, such as channel migration and bar development. As discussed in Sect. 18.104.22.168, during the 1950s and 1960s it was realized that fining-up-ward cycles in fluvial systems could be explained by such processes. The term autogenic processes is now preferred, because they are not necessarily strictly cyclic in nature. Much of the sedimentological research in the 1960s and 1970s was concerned with the recognition and description of autogenic processes, as discussed in Chap. 2. The purpose of the present chapter is to review the present state of our understanding of the subject. Extrabasinal, or allogenic (formerly allocyclic), processes, are discussed in Chap. 11.
