Father of modern geochemistry and global change
Fyfe was the first student from his one-room school to attend university. He received his BSc in 1948 from Otago University, New Zealand, followed by his MSc (1949) and PhD (1952). Early in his career, he made important contributions to the knowledge of isomorphism, studying the behaviour of rock-forming minerals under high temperature and stress. His investigation of metamorphism—the chemical and physical transformation of rocks under pressure and stress at the base of mountain systems—revolutionized the field of metamorphic petrology. While Dean of Science at UWO (1986-90), he established the Interface Science Research Centre. Fyfe’s Canadian research effort focused on the role of fluids and tectonics in creating deposits of precious metals, particularly gold. He did research on a range of biosphere-geosphere interactions, including the role of micro-organisms in concentrating metals and the role of geothermal systems in creating ocean nutrients. Concerned with the environmental implications of human energy consumption, Fyfe conducted research into problems associated with burning coal. His knowledge of the geology of ancient rocks and the movement of fluids in the Earth’s crust were key to research into the possibility of safe geological disposal of high-level nuclear waste. He was also involved in soil erosion studies and prevention. He led the establishment of the Global Change program, a comprehensive international investigation of Earth’s life-support systems.
