Sequence (geology)
In geology, a sequence is a stratigraphic unit which is bounded by an unconformity at the top and at the bottom.[1]
Definition
In a more rigorous and general way a sequence is defined as a
"relatively conformable [...], genetically related succession of strata bounded by unconformities or their correlative surfaces"[2]
Special cases of sequences include type 1 sequences and type 2 sequences.[3] A related concept are parasequences. Contrary to their name they are not smaller sequences.
