Dr. John G. Spray
Planetary and Space Science Centre - Department of Geology
University of New Brunswick

Dr. Spray's research interests include the process of impact cratering on Earth, the Moon and Mars, as well as the meteoritic materials that come from other planets, asteroids and comets.

He studies high impact strikes on the earth and how the friction and shock of impact cause transformations in the earth's rocks and minerals. This includes detailed field studies (mapping, sampling and remote sensing) of impact sites like Sudbury, Charlevoix, Manicouagan and others, abroad.
