In 1994 Dave Prior (now at Otago University) realised the potential of EBSD for Earth Science research. It was in common use in Materials Science and Metallurgy but Since then Dave Prior, John Wheeler, Alan Boyle and Elisabetta Mariani have moved the technique and applications forwards, with other Liverpool staff (Dan Faulkner, Richard Worden, Prof. Yan Lavallee, Jim Marshall) involved in particular projects. In 1999 we were funded for a new machine with a bespoke design including a hot stage which allows us to research into metallurgy as well as geoscience.
