Field Meeting of the International Subcommission on Carboniferous Stratigraphy 'The Historical Type Sections, Proposed and Potential GSSP of the Carboniferous in Russia', August 11-18, 2009

摘要

On August 11-18, 2009 a field meeting of the International Subcommission on Carboniferous Stratigraphy was held for the first time in Russia. The International stratigraphic scale (ISS) of the Carboniferous System subdivided into subsystems, series and stages was ratified by the International Union of Geological Sciences in 2004, but the boundary choices for most stages still remain unresolved. The importance of the meeting was emphasized by the fact that, of seven Carboniferous stages, five have been erected in Russia. However, their boundaries (except for the base of the Bashkirian) are not yet fixed, and their GSSPs are not yet chosen. Show less
