Carbonate mineral

Kambaldaite, NaNi4(CO3)3(OH)3·3H2O, is an extremely rare hydrated sodium described from gossanous material associated with Kambalda type komatiitic nickel ore deposits at Kambalda, Western Australia , and Widgie Townsite nickel gossan, Widgiemooltha, Western Australia.

Kambaldaite crystallizes in the hexagonal system , is light green to blue, and forms drusy to mammilla encrustations on the matrix.

Kambaldaite was first described in 1985 from the gossan of the Otter Shoot nickel orebody, Kambalda, during mining of the gossans material. Kambaldaite, though in lesser and rarer amount, is also found in the Widgiemooltha nickel gossans, probably discovered there in the early to mid-1990s.
