Parasequences: Allostratigraphic misfits in sequence stratigraphy

Parasequences were introduced as the building blocks of seismic-scale systems tracts in the context of low-resolution seismic stratigraphy. Pitfalls of this concept relate to the definition of parasequence boundaries as lithological discontinuities that mark episodes of abrupt water deepening. With this general meaning, ‘flooding surfaces’ may be facies contacts within transgressive deposits, or may coincide with different types of sequence...
