A series of musical phrases where a theme or melody is repeated, with some change each time, such as in pitch or length (example: opening of Beethoven's Fifth Symphony ).Cratonic sequences were first proposed by Lawrence Sloss in 1963; [1] each one represents a time when epeiric seas deposited sediments across the craton, while the upper and lower edges of the sequence are bounded by craton-wide unconformities eroded when the seas receded.Three other sequences, Tippecanoe, Kaskaskia, and Zuni, reproduce these five stages with minor variations imposed by mean elevation of the cratonic interior with respect to base level. The Zuni sequence, because of the relatively high mean elevation of the craton, comes closest to mirroring the behavior of the Sauk. 1. Introduction. The Phanerozoic of North America is characterized by six major unconformity-bound "super" or "mega" sequences (Sloss, 1963, Sloss, 1988, Bunker et al., 1988, Van Wagoner et al., 1990).The oldest, the uppermost Proterozoic-Lower Ordovician Sauk sequence, represents over 120 m.y. of deposition (Palmer, 1981, Sloss, 1988) and can be divided into three subunits, Sauk I ...Multivariate sequence stratigraphy: Tackling complexity and uncertainty with ...
