Name:
Named by C. Milton in 1968 in honor of Julius Kambarage Nyerere (29 October 1964, Butiama, Tanganyika – 5 November 1985, London, United Kingdom), president of Tanganyika and then Tanzania 1964-1985. The original description contained only a name and composition. A later proposed name of natrofairchildite (in another paper that included data) was denied and nyerereite was given priority.
