Abstract

Close scrutiny of apatite fission-track data from Barrandian Lower Paleozoic rocks shows that previous interpretations involving a late Carboniferous to Permian heating stage and the extensive development of pre-Westphalian thrust tectonics are largely speculative. An alternative time-temperature path for the Barrandian sequence based on firmly established geological constraints and an improved version of the AFTSolve annealing kinetic model by Ketcham et al. (2000) is presented as evidence of a simple late Devonian to early Carboniferous Variscan peak heating, followed by a gradual Mesozoic to Tertiary cooling.
