N2 - Shandite occurs in metadunite from the Isua supracrustal belt, west Greenland. It forms a thin (approx 10 mu m) continuous rim on heazlewoodite, Ni3S2, which also contains patches of cobalt-pentlandite, Co7.0Ni1.5Fe0.5S8. Mg- , Ni-rich magnetite is associated with the sulphide aggregates as well. The shandite may have formed by a continuous reaction of the form: pentlandite (Fe,Ni-rich, Co-poor) + H2O rt arrow cobalt-pentlandite + heazlewoodite + shandite + magnetite + H2S, where the water is supplied by the breakdown of serpentine. -L.T.T.
