Anthony J. Naldrett

Anthony James "Tony" Naldrett, FRSC (1933 – 21 June 2020) was an English and Canadian geologist. He was an authority on the geology and origin of nickel-copper-platinum group element deposits, the tectonic setting in which they occur, the petrology of associated rocks, and controls on their composition. He was an expert on the reaction between sulfide and silicate melts, fractional crystallization of sulfide melts, and the role of hydrothermal fluids.
Early life.
Naldrett was born in England. Between 1951 and 1953, he was a pilot in the Royal Air Force.
In 1957, he obtained a degree in geology from the University of Cambridge. Later that year he moved to Canada, where he worked in Sudbury as a geologist for Falconbridge Nickel Mines. In 1959 he moved to Kingston, Ontario to attend Queen's University. He received an MSc (1961) and a PhD degree (1964) for his research on nickel deposits.
Career.
Naldrett took a position working in the Geophysical Laboratory of the Carnegie Institution of Washington. In 1967, he returned to Canada as an Assistant Professor at the University of Toronto. In 1972, he was appointed a full Professor, and University Professor in 1984. He worked there until his retirement in 1998. The university made him an Emeritus Professor.
Naldrett authored or co-authored 254 refereed publications, plus wrote or edited eight books covering his research in geology, mineralogy and chemistry of magmatic sulfide deposits and related rocks. His research covered most of the world's magmatic sulfide ores, including those at Sudbury, the Abitibi Belt, Voisey's Bay, the West Australian Widgiemooltha Komatiite deposits, the Zimbabwe Nickel deposits, deposits of the Raglan and Thompson belts, Norilsk, Pechenga, Jinchuan, the Duluth Complex, the Bushveld and Stillwater complexes, Zimbabwe's Great Dyke, and at the Lac des Îles igneous complex of northwestern Ontario.
In addition to his research, he consulted for over 35 companies including Chevron Corporation, Falconbridge Ltd., Western Mining Corporation, BHP Billiton, Rio Tinto Group, Cominco-American, Voisey's Bay Nickel, and Kennecott.
