regressive systems tract

The regressive systems tract was defined by Embry and Johannessen (1992). In his definition it lies above a transgressive systems tract and is overlain by the initial transgressive surface of the overlying transgressive systems tract. This complete sequence is know as a transgressive-regressive sequence (T-R sequence).

The sediments of this systems tract include the highstand system tract of Posamentier and Allen (1999), and the falling stage system tract defined by Plint and Nummedal, (2000) and/or the systems tract termed the early lowstand systems tract (ELST) (Posamentier and Allen, 1999).
