The change from limnic to terrestrial sedimentation is regarded as a marker of the N/Q boundary in the Carpathian basin. It is roughly synchronous with the Matuyama-Gauss paleomagnetic reversal (million years). The boundary is easy to trace
in mountains, but more difficult to define in basins where oscillations of water level took place. DLO).
The Great Hungarian Plain is the largest sedimentary basin of Europe filled with great thicknesses of Neogene sediments. The complex mapping of deposits showed that during the Quaternary the maximum degree of subsidence was 700 m and in the lowlands
