Ingressions arise from the rise in sea ​​level or the lowering of land masses. Areas affected by ingressions are called ingression coasts . Characteristic for ingressions is a transition from freshwater ( limnic - fluvial ) and mainland sediments to marine sediments in the deposition sequence of sedimentary rocks without special transgression horizons such as e.
