Named in honor of John (Joe) Eric Harms, former chief geologist of Broken Hill Pty., a large Australian mineral and petroleum-producing company. During his pioneering geological exploration in Western Australia, Harms discovered and recognized the Spider, Goat Paddock and Teague Ring impact structures. In the course of a 30-year career with BHP, he led in the discovery of major iron-ore, nickel and zinc-lead deposits, which have contributed importantly to the economy of Australia. (M 27329) _ _.
