Some of the country's foremost geologists and geophysicists will gather at Bowdoin College Saturday, April 16, to share ideas on conducting research using an Electron Backscatter Diffractometer (EBSD).
The daylong symposium, "Microstructure Analysis Using Electron Backscatter Diffraction," is being sponsored by Bowdoin's Kibbe Science Lecture Fund.
Bowdoin was among the first American colleges or universities to add an EBSD to a Scanning Electron Microscope (SEM). The College acquired the EBSD in 2003 thanks to the work of Associate Professor of Geology Rachel J. Beane and a National Science Foundation Grant.
In geology, EBSD is a powerful tool for the observation and analysis of mineral lattice structures. The method is being increasingly used, as more colleges and universities are now learning about the technique and working to establish EBSD labs.
The Bowdoin symposium will bring together scientists who are at all levels of EBSD research, from those just starting to learn about applications relating to the technique to those who are doing cutting edge experiments at the highest level.
Schedule of presenters:
Donna L. Whitney, Professor of Geology and Geophysics, University of Minnesota-Twin Cities
"Metamorphic Microstructures and Mountains"
David J. Prior, Professor of Geology, University of Liverpool
"Watching Metamorphic Processes Happen: High Temperature Experiments Inside an SEM"
Greg Hirth, Associate Scientist, Department of Geology and Geophysics, Woods Hole Oceanographic Institution
"Lattice Preferred Orientations in Naturally Deformed Peridotites: A Link from the Lab to Mantle Dynamics"
Michael John Cheadle, Associate Professor of Geology and Geophysics, University of Wyoming
"Seismic Properties from EBSD Measurements: The Example of Mantle Peridotites"
Interest Group Discussions
The symposium is open to the public and admission is free. Registration begins at 8:30 a.m. in the Druckenmiller Hall Atrium. All presentations will take place in Cleaveland Hall, Room 151. A lunch buffet will be offered at noon in the Druckenmiller Atrium.

The Kibbe Science Lecture Fund was established in 1994 by Frank W. Kibbe '37 and his wife Lucy K. Kibbe. The fund is used to support lectures by visiting scholars on "topics deemed to be 'on the cutting edge' or associated with new developments or research findings in the fields of Astronomy or Geology."
