Abstract
The 40K-40Ar radiometric whole-rock analyses of a series of samples mainly from lava flows intercalated between the fossiliferous sediments of several sites of the Ceské Stredohorí Mountains (Northern Bohemia) has made possible to get results generally ranging between 38.3 ± 0.9 Ma and 23.7 ± 1.3 Ma. They mostly characterize Oligocene ages and, more precisely, the Stampian. They are parallelized with informations provided both by the flora and the lower vertebrate fauna (mainly the fish-fauna) of the studied fossiliferous localities.
