Abstract. Central Europe was affected by a compressional tectonic event in the Late Cretaceous, caused by the convergence of Iberia and Europe. Basement uplifts, inverted graben structures and newly formed marginal troughs are the main expressions of crustal shortening. Although the maximum activity occurred in a short period between 90 and 75 Ma, the exact timing of this event is still unclear. Dating of start and end of basin inversion is very different depending on the applied method. On the basis of borehole data, facies and thickness maps, the timing of basin re-organisation was reconstructed for several basins in Central Europe. The obtained data point to a synchronous start of basin inversion already at 95 Ma (Cenomanian), 5 Million years earlier than commonly assumed. The end of the Late Cretaceous compressional event is more difficult to pinpoint, because regional uplift and salt migration disturb the signal of shifting marginal troughs. Unconformities of Late Campanian to Paleogene age on inverted structures indicate slowly declining uplift rates.

Short summary
Basin Inversion in Central Europe is believed to start during Late Cretaceous (MIddle Turonian) and to proceed probbaly until the Paleogene. Data from different marginal troughs in Central Europe point to an earlier start already in the Cenomanian. The end of inversion is overprinted by general uplift, but probably occurred already in the Late Campanian to Maastrichtian. Both start and end occurred with low rates of uplift and subsidence.
