At the type locality, the Wolfe Creek meteorite crater, Carranya Station, Halls Creek Shire, Western Australia, reevesite occurs as an alteration product of the highly weathered iron-nickel meteorite, forming yellow fine-grained aggregates lining cavities and cracks. Associated minerals include goethite, nickel-bearing maghemite, jarosite, nickel-bearing serpentine, apatite and lipscombite (AM 52.1190-1197, HOM).
At the Bon Accord Nickel deposit, Barberton, Ehlanzeni District, Mpumalanga, South Africa, reevesite occurs as an alteration product of violarite in nickel ore at a contact between quartzite and ultramafic rocks.
