Keck Alaska presents at Kelowna BC

Meghan Riehl (2014), Kate Kaminski (2014), traveled with Professor Garver and four other team members to the 2014 Cordilleran Tectonics Workshop to present their poster on the Cooling and exhumation of the Sitka Graywacke on Baranof Island in Alaska.

Kate and Meghan presented their thesis work on a single poster entitled: “Exhumation of the Chugach-Prince William terrane, Baranof Island, SE Alaska” Their work shows that this part of Alaska cooled rapidly after pluton intrusion in the Late Eocene and early Oligocene (c. 30 Ma).

The Keck Alaska research team has six students, all of whom presented three different posters that detailed results on the age of the Sitka Graywacke, its provenance, and the evolution of the Crawfish Inlet Pluton that intrudes these rocks in SE Alaska.

The Cordilleran Tectonics Workshop is an annual meeting held at Canadian universities, and it is attended by students, faculty, and professionals working on understanding the evolution of the Canadian Cordillera. The geology of Alaska, especially SE Alaska is particularly important because the rocks are allied with those of the outer belts of British Columbia.
