A major unconformity separates it from the lower Tippecanoe sequence . The basal—that is, the lowest and oldest—units of the Kaskaskia consist of clean quartz sandstones eroded …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. At the cratonic margins the bounding unconformities tend to disappear in continuous ...

Cyclothems are cyclic stratigraphic sequences that are unique to the Pennsylvanian and earliest Permian periods within the US Midcontinent, that formed as a result of marine transgressions and regressions (rise and fall of sea level) related to the waning and waxing of ice sheets at the South Pole. The "perfect" Midcontinent cyclothem deposit ...

The possible affinity of the Sauk sequence with this pattern of cratonic differentiation is less clear. The lack of siguificant cratonic-interior Sauk record for anything except the Late Cambrian and Early Ordovician precludes observational data of stage 2, which might be expected to occupy a position in time immediately preceeding the ...The Sloss cratonic sequences record the history of this dynamic tectonic environment, in the form of episodes of transgression, regression and erosion and non-deposition, generated on a timescale of tens of millions of years. These sequences occur across the craton, on areas of platform, as well as in the four main intracratonic basins, yet ...
