Short summary
The study presents and discusses mid- and near-infrared spectra of three Mg–Ni mineral series (serpentine-like and talc-like minerals, sepiolite) commonly found in reactivated faults and sequences of clay infillings of the New Caledonian Ni-silicate deposits. This spectroscopic study sheds light on the nature of the residual mineral phases found in the clay infillings (serpentine-like minerals) and reveals the aptitude of the newly formed minerals (talc-like minerals and sepiolite) to store Ni.
