Global Stratotype Section and Point (GSSP) for the lower boundary of the Sakmarian Stage of the Cisuralian, the Permian (South Urals, Russia)
Abstract
Usolka Global Stratotype Section and Point (GSSP) for the base of the Sakmarian Stage of the International Permian Timescale is ratified for the first time in Russia. The deep-water condensed Usolka section and the subsidiary thick shallow-water Kondurovka section with abundant fossils were studied for justification of the base of the Sakmarian Stage taking into account all present-day international requirements.
