Barry Butler studied geology at the University of Cambridge and then as a field geologist with the Attock Oil Company in Pakistan, before returning to Cambridge to do research on the Moine Schists in Ardnamurchan, Argyllshire, obtaining his Ph.D. in 1960. He moved to the University of Oxford as Lecturer in Mineralogy. He became interested in the mineralogy of slags and refractories used in the metal production industry, and in 1969 – 70 had a sabbatical year with the British Steel Corporation. For several years he was Managing Editor of the Journal of Petrology. In 1988 he published “Interpretation of Geological Maps”, co-authored with J.D.Bell. He has had a connection with the Open University since its foundation, as an examiner and student (gaining a degree in social sciences). For many years he was a tutor in geology, first in South Region and more recently in North Region. He is an active member of the North East Yorkshire Geology Trust – an organization whose mission is to promote the understanding of rocks and scenery.
