Garnierite is a hydrosilicate mineral of nickel and magnesium, often associated with laterite deposits. It is generally green in color, ranging from light to dark green, due to its nickel content. Garnierite is mainly found in tropical and subtropical regions where climatic conditions favor the formation of laterites. It forms by alteration of ultrabasic rocks rich in olivine, such as peridotites and dunites, in the presence of water. Garnierite is an important source of nickel, and is therefore widely exploited for the extraction of this metal. Its density varies between 2.2 and 2.6, and its hardness on the Mohs scale is generally 3 to 4.
