Name:
Named in 2002 by Billy P. Glass, Shaobin Liu, and Peter B. Leavens in honor of Alan Forrest Reid (26 March 1931, Gisborne, New Zealand - 17 January 2013, Adelaide, Australia), Commonwealth Scientific and Industrial Research Organisation (CSIRO), who first produced the phase in high-pressure laboratory experiments in 1969. At CSIRO he was, at different times, Director of Minerals, Energy and Construction; Director of CSIRO's Institute of Energy and Earth Resources; and Chief of the Division of Mineral Engineering. He also analyzed Apollo lunar samples and codescribed the mineral tranquillityite.
Dimorph of:
A high-pressure polymorph of Zircon with the scheelite structure.
