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.

Cratonic sequence is a(n) research topic. Over the lifetime, 3 publication(s) have been published within this topic receiving 34 citation(s).

Diatonic sequences preserve the interval size, but not the quality, to ensure that they stay within a single key.
