Recent study acquired new insights in the development of the Southern Permian Basin (SPB). Rather than one basin, the SPB actually comprises three basins, separated by subtle swells. These basins have both a different origin and subsequent history. High-resolution stratigraphic correlations of the Permo-Triassic interval were carried out to (i) align the various stratigraphies, and (ii) to define a basin-wide framework for the SPB area. A series of high-resolution paleogeographic maps capture the current insights in basin evolution.

Permian hydrocarbon plays extend over the entire SPB, whereas Triassic plays are restricted mainly to the western parts.
