The 12th International Symposium on the Ordovician System will be hosted on the campus of James Madison University in Harrisonburg, Virginia, June 8-11, 2015. Visit the web site at to download the Second Circular.

 The scientific sessions in Harrisonburg will be preceded and followed by geological excursions to study the Ordovician successions of the Appalachian Mountains of the Eastern US. A field excursion is also planned for the Ordovician carbonate and siliciclastic deposits of Oklahoma (site of the Katian GSSP), and a field excursion is planned to the spectacular succession of Ordovician dark shale in Idaho.  The 5 field trips are described in more detail in the Second Circular and on the web site.

Themes for the 12th ISOS include Ordovician climate, isotope stratigraphy, biostratigraphy, regional stratigraphy, paleoecology and paleobiogeography, and we welcome contributions on all aspects of Ordovician geology.

Please complete the pre-registration survey at or download the pre-registraion form from the ISOS2015 web site and submit it to 2015ISOS at<mailto:2015ISOS at>.

We look forward to seeing you in Virginia in 2015!
