North America, for example, has four cratonic sequences dated to the Paleozoic. In each sequence, rocks indicate that the North American craton was covered by transgression of a shallow sea, which then regressed. The study of cratonic sequences is called sequence stratigraphy. • In sequence stratigraphy, rocks are studied within a time- stratigraphic framework related to facies and bounded by unconformities.

and Transvaal supergroups in South Africa; and (3) cratonic rift basins, of which an example is the Ventersdorp in South Africa.
