Two different modes of the origin of Pleistocene pediments: an example from the Central Moravian Carpathians, Czech Republic
The Pleistocene soft rock pediments in the Central Moravian Carpathians developeddue to different geomorphic processes. At a locality situated between Nesovice and Brankovicevillages, it was mainly downwearing of the former river terrace and the underlying Lower Miocenestrata due to development of a small flat, at present dry valleys (dells). At Slavkov u Brna(Austerlitz), in turn, the leading process affecting the same sediments as at the previous localityconsisted in the recession of the northern valley side of the Litava River. The main reason for thedevelopment of the lower segment of the pediment at Slavkov u Brna in the contact zone withthe Litava River terrace was surface runoff. The present appearance of the pediments at bothlocalities is an effect of periglacial processes active in the Middle and mainly Late Pleistocene.Thus, the same landforms (pediments) developed in comparable geologic and climate conditionsdue to different processes caused by local geomorphic factors.
