PRE-VARISCAN BASEMENT ROCKS IN SOUTHERN POLAND - WHERE IS THE SOUTHEASTERN MARGIN OF EASTERN AVALONIA (CADOMIA)

Pre-Variscan basement in southern Poland is poorly exposed and thus kn own mostly from subsurface data. The availability of the latter is rev iewed for terrains located between the Sudetes and the East European P latform. In these terrains the following relationships have been docum ented: Cadomian granitoids capped by Variscan flysch, Palaeozoic platf orm strata, Palaeozic folded and partly thermally altered successions, and low-grade metamorphic rock overlain by Middle Cambrian strata. In view of their interrelationships the location of the Avalonia-Baltica suture in southeastern Poland is uncertain.
