The 14 outcrop samples range stratigraphically from Variscan crystalline basement through the deposits of Pennsylvanian and Permian to Triassic. Fission track data reveal significant cooling events in Mesozoic and Cenozoic. Apatite fission track data yield ages indicating Upper Permian annealing over 120°C of the Palaeozoic rocks, and Middle Triassic partial annealing (over 80°C). An overall burial is suggested deeper than 3 km, assuming thermal gradient of 30°C/km. Burial events (0.1 – 0.2 km/Ma) were found in latest Pennsylvanian and Early Permian in the central and western parts of the basin. Late Permian and Triassic burial events were identified in eastern part of the KPB – in TNSB.
