... minerals or mixtures. Thus, genthite is a mixture of 20 per cent pimelite and 80 per cent nickeoloan serpentine-group mineral; röttisite is pimelite; de saulesite is pimelite; revdanskite is chiefly pimelite; garnierite, nepouite, noumeite are mixtures of pimelite, nickel serpentine-group minerals...

... minerals in Ni-laterite deposits. The chemical and structural characterization of garnierite minerals from many nickel laterite deposits around the world show that this group of minerals is formed essentially by an intimate intermixing of three Mg-Ni phyllosilicate solid solutions: serpentine-népouite...

... are named falcondoite ( Springer, 1976 ; Tauler et al ., 2009 ). The common association of two or more components of these mineral groups ( e.g . SL and TL, TL and Sep) in white and greenish ore areas led us to adopt the field terms ‘deweylite’ and ‘garnierite’ for the white (Mg-rich) and green (Ni...

Figure 1 Garnierite, the serpentine-group mineral discovered by Jules Garnier, is the Ni ore that has been mined in New Caledonia since 1873. The strong green colour reflects its high nickel content (usually 20%–30%). More magnesian garnierite is light blue. The brown rocks are altered peridotite

... 1966 ). Since then, the term garnierite has been widely used in the literature to refer to the group of green, fine-grained, poorly crystallized, Ni-bearing magnesium phyllosilicates, including serpentine, talc, sepiolite, smectite, and chlorite, often occurring as mixtures (e.g., Faust 1966...

... and much of the orthopyroxene and serpentine minerals. Secondary minerals formed are predominantly hydrated ferric oxides (goethite); minor amounts of a montmorillonite mineral, chlorite, and talc were also identified. The kaolin group and bauxite minerals were not found. Except for garnierite...

More broadly, the improvement of band attributions especially in near infrared contributes to develop the infrared...
