Dear Colleagues:
We would like to draw your attention to the symposium entitled:
Development of Accretionary Orogens: a Symposium Celebrating the Career of Cees van Staal –
which will take place during the 2017 GACMAC, in Kingston, Ontario, May 14-18, 2017
This symposium celebrates the outstanding contributions of Cees van Staal to the understanding of orogenic processes. We welcome the presentation of new data and concepts concerning the development of modern and ancient accretionary orogens. This session is intended to highlight both recent advances in our understanding of accretionary orogenic processes, and the major problems that remain. Topics might include (but are not restricted to) mechanisms of subduction initiation; development of fore-arc, arc, and back-arc structures and magmatism; relationships between accretionary processes and mineral deposits, processes leading to accretion and terminal collision, crustal growth and consumption, cratonization, accretionary orogenic processes through time, and analytical approaches to solving tectonic problems.
The conference website is: http://www.kingstongacmac.ca/
Kingston is accessible via Toronto (3 hours via train), Ottawa (2 hours by bus), or Montreal (2.5-3 hrs hours by car) airports.
In conjunction with the meeting, Cees will co-lead a 5-day field trip (with Alex Zagorevski) across the island of Newfoundland. The Newfoundland Appalachians trans-island field trip (Stephenville to Gander) will take participants to some of the best preserved ophiolites, melanges and island arc terranes in the Appalachian mountain belt. Crossing several suture zones, including the main Iapetus suture, participants will explore the tectono-stratigraphy of the various oceanic and micro-continental terranes and their tectonic complex tectonic interactions during successive accretion to a progressively expanding composite Laurentia from the Early Ordovician to Devonian. The trip will show spectacular geology framed by the beauty and ruggedness of Newfoundland. After the trip is over, participants will be invited to launch Cees on a Viking sailing ship in St. John’s Harbour in the direction of the Valhalla orogen (sensu Cawood et al., 2010)!
Please feel free to forward this message to colleagues who may be interested.
Regards to all. We hope to see you in Kingston.
