Name:
In recognition of Charles Edward Michener (Red Deer, Alberta January 1907- Toronto 15 October 2004), Canadian exploration geologist, International Nickel Co., who is credited with the discovery of a number of major ore deposits, including the Thompson nickel belt in Manitoba and a laterite deposit in Indonesia. Michener discovered and first studied the mineral that was later named after him (Horváth 2003).
Chemically similar to unnamed species: 'UM1961-11-Te:BiPd', 'UM1970-27-Te:BiPd', 'UM1976-31-Te:BiPdSb'. See also kotulskite, Unnamed (Rh-Analogue of Michenerite), and UM1997-55-Te:BiPd.
