Eric Walter Mountjoy PhD, FRSC was an award-winning Canadian emeritus professor at McGill University. He was a foremost expert on sedimentology, Devonian reefs, carbonate diagenesis, porosity development and the structure of the Rocky Mountains. His research has provided useful applications to the petroleum industry.

Early life[edit]

Mountjoy was raised near Calgary, Alberta in the 1930s and 1940s. Regular visits to the nearby mountains led him into a career of geological research.

He obtained a B.A.Sc. from the University of British Columbia in 1955 and a Ph.D. from the University of Toronto in 1960.


From 1957 to 1963, Mountjoy worked for the Geological Survey of Canada, first as a Technical Officer, then as a Geologist.

He left the survey to be an Assistant Professor at McGill University. In 1969, he was promoted to Associate Professor. In 1974, he was made a Full Professor. Between 1993 and 1998, Mountjoy was a Logan Professor. At the time of his death (2010) he was professor emeritus, Department of Earth and Planetary Sciences, McGill University.

Most of Mountjoy’s research has concentrated on Jasper Park's Miette area, and in particular on its exposed coral reefs from the Devonian period (395 million to 345 million years ago).

Mountjoy with Queen's University professor, Raymond A. Price have mapped most of the Canadian Rockies between Banff and Jasper. This work produced cross-sections, which have become classic representations of the structure of a thrust-fold mountain belt and have been published in many textbooks.

He has also studied ancient and modern reef geology, carbonate petrology and diagenesis, carbonate reservoirs and stratigraphy. He has visited and applied his knowledge to the geology of Australia, China and Germany.

He has directed the research of over 50 master's and doctoral students, many of whom have gone on to become professors.

Mountjoy died June 18, 2010 in Montreal, Canada.
