Marine regression

As regression (from Latin regredior, regress ) is referred to in geology the retreat of a shoreline and it provoked changes in the Sedimentationsdynamik of the sedimentary basin affected. A regression may be the result of tectonic elevation of a land mass, the progressive Einschüttung of sediments in the coastal area of ​​a land mass or a reduction in the global ( eustatic ) sea-level, for example, by climate-induced binding of water in continental ice masses.

A regression manifests itself in the sedimentary sequence by a shift from, for example, a more marine depositional environment to a more terrestrial Ablagerungsmillieu or, not infrequently, in the form of hiatuses.

In contrast, the transgression, when the shoreline moves inland.
