A cratonic sequence (also known as megasequence, Sloss sequence or supersequence) in geology is a very large-scale lithostratigraphic sequence in the rock record that represents a complete cycle of marine transgression and regression on a craton (block of continental crust) over geologic time.- The last Cratonic sequence began at the late Cretaceous - The Laramide Orogeny began at the start of the Tejas sequence - The mountain range that is the result of the Laramide orogeny is the Rocky Mountains.
