Structural Geology and Tectonics Forum Program

June 11-18, 2012, Williams College, Williamstown, Massachusetts

Organizing committee: Paul Karabinos, Basil Tikoff, Richard Becker, Yvette Kuiper, Phil Resor, and Matty Mookerjee

This NSF-sponsored Forum brought together over 100 structural geologists to discuss important areas of research in structural geology, to share current research, and to take part in field trips and workshops. You can find more information about the 2012 Forum at the Structural Geology and Tectonics Forum web page. The next Structural Geology and Tectonics Forum will be hosted by the Colorado School of Mines during the summer of 2014.

The purpose of this web page is allow those presenters at the Forum who wish to do so to make their presentations available to people who could not attend the Forum.

Note: This page is incomplete and under construction. As workshop presenters submit their poster and PowerPoint files, we will link them to their titles below.
