Allocyclic Sequences (or Allogenic sequences)

Cyclic sequences

Sequences

 

 

Einsele et al (1991) note that processes that are influenced by events external to the depositional basin including climate, tectonic movement and eustasy primarily control these sequences. Beds of these cyclic sequences have often have widespread continuity with the processes involved having operated in several adjacent or widespread basins. Examples may include the sequences of Vail et al 1971.
