Sequence (geology)
From Wikipedia - Reading time: 3 min
In geology, a sequence is a stratigraphic unit which is bounded by an unconformity at the top and at the bottom.[1]
Definition
[edit]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 and related concepts
[edit]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.
