PERMIAN-TRIASSIC BOUNDARY DEPOSITS IN FRAMING STRUCTURES OF THE EAST SIBERIAN PLATFORM

Abstract

The first description of the stratotype of the Ust'-Kel'ter Horizon with its specific characteristics is given. A new stratigraphic unit, the Marininskii Horizon, is distinguished and substantiated, and its stratotype is described. The Marininskii and Ust'-Kel'ter horizons continue upward the succession of continental Permian-Triassic stratigraphic units of Siberia. Their recognition allows us to address the problem of age and correlation of the Permian-Triassic boundary deposits in the northern Siberian platform and its framing structures.
