Gravitational mass movements (landslides) have been one of the most efficient processes contributing to the morphogenesis of the Outer Carpathians formed of flysch, siliciclastic-clayey rocks. Such processes often produce non-karst caves in sandstones. Dating of calcite speleothems developed in caves hosted by sandstone with calcareous cement seems to be a suitable method to reconstruct phases of slope evolution in this region. The paper discusses the usefulness of radiocarbon (14C) and U-series dating of speleothems in non-karst caves in the reconstruction of mass movement chronology and evaluates possible reasons for discrepancies between both methods. The obtained speleothem age data are used to improve the existing knowledge on the chronology of mass movements during the Late Glacial and Holocene in the flysch Carpathians.
