Cratonic sequence
The Kaskaskia sequence was a cratonic sequence that began in the mid-Devonian, peaked early in the Mississippian, and ended by mid-Mississippian time.

The Sauk sequence was the earliest of the six cratonic sequences that have occurred during the Phanerozoic in North ...Our study thus deciphers the exact timing and sequence of events through the early Darriwilian as follows (Fig. 8): Significant cooling first occurred around 469.2 Ma in the top of the B ...The Great Unconformity and Sauk Megasequence, plus the later planation surfaces, can be explained by Flood catastrophic processes. A possible model for the formation of these features follows. The early Flood unleashed the mechanism of the Flood, which I think was caused by impacts. 9 The very early Flood should be the most catastrophic part of ...
