The occurrence of native nickel-iron in the serpentine rock of the eastern townships of Quebec province / by E. H. Nickel. : M38-1/57-1960E-PDF

"Native nickel-iron has been found over a wide area in the serpentinized asbestos-bearing rock of the Eastern Townships of Quebec. The chemical composition (average of two analyses) is: nickel 71.0%, iron 25.3%, cobalt 3.5%, and copper 0.2%. The nickel-iron forms a single-phase alloy with a face-centred cubic structure and a cell constant which varies from 3.551 to 3.555 A. It occurs chiefly as tiny spheroidal grains, most of which are less than 10 microns in diameter, but also as larger crenulated grains up to 100 microns in diameter, and as acicular crystals up to 100 microns in length. The nickel-iron appears to have been formed as the result of the breakdown, during serpentinization of primary olivine and enstatite containing about 0.2% combined nickel."--Abstract.
