Resumen


Se propone a continuación una revisión estratigráfica del Criogénico terminal, el Ediacárico y el Cámbrico temprano en la Platafora Siberiana. Todas las unidades estratigráficas neoproterozoicas tardías llenan la cuenca remanente de Sayan. El registro sedimentario se adscribe al grupo Criogénico terminal y Ediacárico de Oselok y a la formación inferior cámbrica Ust’-Tagul. Se pueden subdividir en miembros a partir de su característico contenido en Dickinsonia.

Palabras clave
