Abstract:

In the last 10 years the Subcommission on Triassic Stratigraphy increased speed in the definition of the GSSP of the Triassic Standard Global Chronostratigraphic Scale. In 2001 the base of the Induan has been defined in China and few years later in 2005 the base of the Ladinian has been defined in Italy. Among the GSSP candidate sections which are at the present under discussion there are two sections in Italy with a great potential. Prati di Stuores/Stuores Wiesen (Dolomites) has been finally selected by the Task Group as the only candidate for the base of the Carnian stage and the final ballot is in progress. Pizzo Mondello (Agrigento) is one of the two candidates for the definition of the base of the Norian stage and a final decision is expected by 2009.
The italian successions exposed in Lagonegro and western Sicily might also have some potential for the definition of the base of the Rhaetian, but more work is necessary to come to a selection of a possible candidate section.
