Emmons, William Harvey 

Born Feb. 1, 1876, in Mexico, Mo.; died Nov. 5, 1948. American geologist.

Emmons received the Ph.D. degree from the University of Chicago in 1904. He became a teacher there in 1907 and a professor in 1909. From 1911 to 1944 he taught at the University of Minnesota and was director of the Minnesota Geological Survey.

Emmons’ chief works dealt with the theory of ore formation. Emmons proposed what is known as the batholithic conception, which considered the questions of the genetic relationship between hydrothermal deposits and intrusive rocks and the zonal arrangement of deposits in the roof of granitoid batholiths. He also described the processes of natural enrichment of ores in the zone of oxidation.
