Chromatic sequences differ from diatonic sequences in that both the size and quality of the interval of transposition is maintained throughout the sequence. Diatonic sequences preserve the interval size, but not the quality, to ensure that they stay within a single key. Remember, with all sequences, the voice leading must be consistent within ...

The 4Internally, Megasequences consist of sequences, usually arranged in sets, reflecting comparable depositional process. These sequences are usually referred to as third-order depositional sequences and reflect a duration of between 0.5 and 3 Ma (Haq et al., 1987), although the original definition of Vail et al. (1977a) carried a range of 1–10 Ma.Cratonic sequence in North America / From Wikipedia, the free encyclopedia.

Sequence stratigraphy is an informal chronostratigraphic methodology that uses stratal surfaces to subdivide sedimentary successions. Unlike most traditional lithostratigraphic units (NACSN, 1983), which are defined as regionally mappable packages (members, formations, groups) of similar lithologies (rock types), sequence stratigraphic units trend across traditional lithostratigraphic ...
