Cratonic sequence.

Cratonic sequences are large-scale lithostratigraphic units representing major transgressive-regressive cycles bounded by craton-wide unconformities. They are convenient for studying the geologic history of the Paleozoic because the transgressions are commonly well preserved. They are widespread and easy to map and correlate.
