John Green received his Bachelor's degree from Dartmouth College and did his graduate work at Harvard, receiving a Ph.D. (1960). He joined the University of Minnesota, Duluth in 1958. Green's interests are in mineralogy and petrology, volcanology (especially plateau lavas), geology of the Lake Superior region and the Midcontinent Rift System, and environmental geology.
