This cooperative study by Hungarian and American geologists and geophysicists, demonstrates the power of the combination of modern paleomagnetic techniques and seismic profiling in working out the stratigraphy of a basin, with only limited paleontologic and isotopic control. Indirect evidence suggests that lake levels in the Pannonian inland sea (a remnant of the Paratethys), although isolated from the world's oceans, were affected by eustatic sea-level changes. Four hiatuses identified by seismic profiles near the northern margin of the Pannonian Basin and inferred to represent non-deposition between 11.5 and 10.5, 7.9 and 7.6, 6.8 and 5.7, 5.4 and 4.6 million years ago. Comparing these hiatuses with the eustatic sea level change curves the accordance is close and systematic. This indicates that the sea level of the Pannonian Inland Sea that became gradually isolated from the world oceans fluctuated in the same phase as global sea level. The hiatus between 6.8 and 5.7 Ma is tentatively correlated with the Messinian global stage during which time evaporite deposition in the Mediterranean was widespread--the so-called Messinian salinity crisis.
