Norman J. Silberling (1928-2011)

On September 27, 2011, Norm Silberling peacefuly passed away in Colorado USA. Norm was a principle contributer, along with Tim Tozer, on the development of the North American time scale for the Triassci and made significant advances to our undersanding of the complex history of the accreted terranes of the American Cordillera. A gentle man who selflessly shared his vast knowledge, he was always willing to provide assistance and sound advice

 

Albertiana moved to new server.

The official publication of the STS, Albertiana, is now avaialble on SUNY Cortland's webserver. The newly designed web presence should provide Triassic researchers a more stable and user friendy experience. Current issues and archived volumes can be downloaded in pdf format.

Timothy Edward Tozer (1928-2010)

On December 26, 2010, Tim Tozer passed away in Vancouver, B.C. Canada. He was a major figure in the Triassic world for many decades and contributed greatly to our science. In honour of his contributions, Michael Orchard held a special session on the Triassic at the 20th Canadian Paleontology Conference at the University of British Columbia, Vancouver, Canada. 19-22 August 2011.

 

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.

Stage Boundary Task Groups

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.

Listing of Task Groups

Base Rhaetian Task Group,
L. Krystyn, chair.
Base Norian Task Group, M. Orchard, chair
Base Carnian Task Group,
M. Gaetani, chair. Task Group work likely completed *
Base Ladinian Task Group,
A. Baud, chair. Task Group work completed **
Base Anisian Task Group,
E. Gradinaru, chair.
Base Olenekian Task Group,
Y. D. Zakharov, chair.
Base Induan Task Group,
Yin Hongfu, chair. Task Group work completed ***
Non-marine Boundaries Task Group,
S. 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.

Meetings


FUTURE MEETINGS

July 19-23, 2015. STRATI 2005. 2nd International Congress on Stratigraphy (Graz, Austria). The congress follows the invitation by the International Commission on Stratigraphy (ICS) of the International Union of Geological Sciences (IUGS) to be held in Graz (Austria), July 19-23, 2015. The congress will be open to all topics in stratigraphy. The technical program will range from the Archean to the Holocene, across all techniques and applications of stratigraphy and the discoveries that the stratigraphic record reveals about the Earth system. In addition, it will also serve as the primary venue for ICS business, for ICS subcommissions to meet and awarding the ICS stratigraphy prizes. For more information, visit the conference website here or downlowad the 1st circula here.

August 27 - September 1, 2015. 2nd Boreal Triassic Conference & 12th International Workshop on the Permo-Triassic (Svalbard). The conference is initiated by the International Triassic Workshop Group but is also open for all geologists. Extensive work on the late Permian and Triassic succession of Svalbard has taken place the last years. We thus expand our conference to present these results of interest to the scientific community and to the ongoing exploration companies now active in the Barents Sea. Just finished thesis work and ongoing work will also be presented, also in poster sessions. For more information, visit the conference website here or downlowad the 1st circular here.

 

PAST MEETINGS

2013

February 12-16, 2014. Pan-European Correlation of the Triassic: 11th International Field Workshop - NW Gondwana margin of the Neo-Tethys (Negev, southern Israel). This workshop offers participants the opportunity to Triassic succession in southern Israel (Negev, Makhtesh Ramon, Makhtesh Areif). The Triassic succession is outcropped in the region which is considered to be a future UNESCO Geo-park, named “Makhteshim Country”. This is not only because of the abundantly interesting geological sites, but also due to its archaeological and ecological value.

September 23-27, 2013. Pan-European Correlation of the Triassic: 10th International Field Workshop - Permian and Triassic of the eastern Iberian Ranges, Spain. This workshop offers participants the opportunity to study, Triassic and Jurassic sequences every day in the eastern Iberian Ranges, in Cuenca and Teruel provinces. Stops will include Permian and Triassic (continental and marine) sections as mentioned above. Description of the stops will be detailed in the second circular. Contact José López-Gómez for more information.
