ABOUT THE PROBLEMS OF STRATIGRAPHY VENDIAN AND PALEOZOIC OF THE NORTH ALTAI
The Vendian and lower Paleozoicis well studied. Controversial is the age of revenue and Charysh Suite. Fractional dismemberment lithologic-stratigraphic sections of the Ordovician and Silurian cannot be extended to the entire territory structure-facies zones due to weak paleontologicheskii of isoindole. The Devonian deposits are the most difficult to study. This is due to the focal distribution of volcanism, frequent changes in marine conditions continental, both laterally and vertically and complex allochthonous structure of the territory. The dismemberment and correlation of Devonian deposits is controversial in some cases. It isestablished that the Basargin location of the middle Devonian flora has elements protopteridae lower EMC age.
