|Name:||Named in 1980 by Paul Piret and Michelle Deliens in honor of Gordon Comblain [August 11, 1920 Hackney, London, England, UK - 1996 Brussels, Belgium]. Comblain, a Belgian citizen, worked as a mining engineer from 1946 till 1965 for the Société des Mines d'Etain du Ruanda-Urundi and did mining and exploratory missions in Central Africa. From 1965 until his retirement in 1985, he worked as a laboratory technician for the department of mineralogy of the Koninklijk Museum voor Midden-Afrika, Tervuren, Belgium.|
