This spring and summer there will be several opportunities to share research and discuss ideas about the Late Jurassic to Eocene evolution of the North American Cordillera and in particular the idea that the margin likely had a dominantly oblique-convergent component during this time. We invite submissions to the following:
2023 GSA Cordilleran section meeting in Reno, Nevada, May 17th-19th
Session T6. Late Jurassic to Eocene Tectonics of the North America Cordillera: Evolving and Emerging Models
Conveners: Basil Tikoff, Stacia Gordon, Andrew Barth, Cathy Busby, Robinson Cecil, Sarah Roeske, and Michael Wells
This session will investigate the Late Jurassic to Eocene tectonic history of the North American Cordillera, from Mexico to Alaska. We encourage contributions from geoscience disciplines that constrain unanswered questions including the timing of orogenic events, role of strike-slip faulting, subduction polarity, the size of closed ocean basins, etc.
This session will be run in a different format than normal sessions. Talks will be divided into three groups by region: northern, central, and southern Cordillera, and for each group, there will be keynote speakers that will give longer (30 min) presentations with different views of the Cordilleran history. Keynote speakers will include:
Northern Cordillera: Robinson Cecil (CSU-Northridge); Stephen Johnston (U. of Alberta); Terry Pavlis (UT-El Paso)
Central Cordillera: Peter DeCelles (U of Arizona); Spencer Fuston (U. of Houston); Bernie Housen (Western Washington U)
Southern Cordillera: Robert Hildebrand; Michelangelo Martini (Universidad Nacional Autónoma de México)
We hope these keynote talks will stimulate lots of discussion. After these presentations, we will have standard 15 mins talks of general contributions presenting recent to new data from the Cordillera.
