Cratonic sequence.

A cratonic sequence is a very large-scale lithostratographic sequence that covers a complete marine transgressive-regressive cycle across a craton. They are also known as "megasequences", "stratigraphic sequences", "sloss sequence" or simply "sequences." Cratonic sequences were first proposed by Lawrence Sloss in 1963; each one represents a …31.

The time spans of cratonic episodes were: (1) Oscillatory—much of the Cenozoic, including the present, and the period from Pennsylvanian to Early Jurassic (time spans of Appalachian-Hercynian, Laramide, and late Alpine orogenies) ; (2) Emergent—latest Precambrian, early Middle Ordovician, and Early Devonian (lacunal intervals between ...

These interregional unconformities subdivide the cratonic stratigraphic column into six sequences—major rock-stratigraphic units (of higher than group, megagroup, or supergroup rank) which can be identified, where preserved, in all cratonic interior areas.
