Welcome to the website of the Subcommission on Triassic Stratigraphy (STS). Under the auspicities of the International Union of Geological Sciences (IUGS) and International Commission on Stratigraphy (ICS), the STS is charged with the establishment of a standard, globally applicable stratigraphic scale for the Triassic system.
Chair: Michael J. Orchard, Vancouver, Canada
Vice Chair: Marco Balini, Milano, Italy
Vice Chair: Yin Hongfu, Hubei, Peoples Republic of China
Secretary General: Christopher A. McRoberts, Cortland, USA
Following recent vote by STS, the new 2008-2012 (to take effect at the Olso IGC meeting) will be:
Chair: Marco Balini, Milano, Italy
Vice Chair: Mark Houslow, Lancaster, UK
Vice Chair: Jiannan Tong, Hubei, Peoples Republic of China
Secretary General: Christopher A. McRoberts, Cortland, USA
The Base of Carnian unanimously passed by both base-Carnian Task Group and STS!
The proposal by Mietto et al. (see Albertiana, v. 36, 2007) for the Global Boundary Stratotype Section and Point (GSSP) defining the base of the Carnian Stage of the Triassic has passed both the base-Carnian Task Group and STS voting membership by unanimous vote. Balloting is currently underway by the IGC voting membership.
The Triassic has a new GSSP! Base of Ladinian successfully ratified by IUGS.
The proposal by Brack et al.
for the Global
Boundary Stratotype Section and Point (GSSP) defining the base of the
Ladinian Stage of the Middle Triassic to be the base of
Eoprotrachyceras curionii at the Bagolino section of
Italy
has passed the ICS by majority vote and has been ratified by
the
IUGS at its recent meeting in Lithuania.

The STS publishes a semiannual Newsletter, Albertiana. Edited by Wolfram Kuerschner (Utrecht), Albertiana has its own website which can be found by clicking here.
Task Groups of the STS are organizational bodies created for the selection and definition of the lower boundaries of the stages of the Triassic System. Currently, there are six active task groups, and two inactive ones that have completed their tasks. Discussion forums for active Task Groups are only accessible to voting and corresponding members of the STS and require a password. Please email the STS chair if you would like to contribute to the discussions and were not provided with a password.

Lucas, chair.
*As of January, 2008, the base-Carnian Task Group has forwarded a GSSP proposal to the STS for balloting. The proposed boundary is defined at the first appearance of the ammonoid Daxatina canadensis (Whiteaves) which is coincident with the base of the D. canadensis subzone of the Trachyceras zone in the Prati di Stuores/Stuores Wissen section of northern Italy.
**In, 2005, the base of the Ladinian Stage was approved by the STS and ratified by the ICS and IUGS. The boundary is defined at the first appearance of the ammonoid Eoprotrachyceras curionii, in the Bagolino section, Province of Brescia, northern Italy.
***In 2001, the base of the Induan Stage (and therefore the Permian/Triassic boundary) was approved through majority vote by the STS and ratified by ICS (Yin et al., 2001). The boundary is defined at the first appearance of the conodont Hindeodus parvus at the base of Bed 27c of Meishan section D, Changxing County, Zhejiang Province, South China.
