Komatiites contain some of the world’s highest-grade nickel-sulphide deposits. Accordingly, the development of reliable prospectivity indicators to guide exploration towards mineralised komatiite units has been a long-standing goal. Specifically, the development of effective resistate indicator minerals, analogous for example to the use of garnet in diamond exploration, would be pivotal in the exploration for mineralised komatiites.
