UNDECIDED AND DEBATABLE QUESTIONS OF MESOZOIC AND CENOZOIC GEOMORPHOLOGY, PALEOGEOGRAPHY AND GEOLOGY OF SOUTH SIBERIAN MOUNTAINS

Abstract

During excursions and field meetings associated with All-Russian Conference on arguable problems of geomorphology paleogeography and geology of South Siberian Mountains some interesting results were obtained: 1 - several new paleo-seismodislocations were discovered; 2 - tracers of Middle Pleistocene glaciation of piedmont type were revealed; 3 - new data were obtained which proves the absence of Upper Cretaceous marine sediments in the southeastern Altai in contrast to previous opinion (Zhykin et al., 1999).
