rhythms and cycles

sequence

tempestite

turbidite

Auto cyclicity refers to cyclic deposition that is not forced by external factors like climate cycles. What results are the auto genetic sequences. (Dott, 1998, Einsele et al 1991) notes that autocyclic sequences are primarily controlled by processes that occur in an evolving sedimentary prism. The beds of these sequences have limited continuity. Examples include non-periodic K-bentonite beds, seismically deformed horizons (seismites), tempestite, or turbidite beds, migration and superposition of channel and lobe systems in fluvial settings, deltaic systems and deep-sea fans.
